The best flying insect trap refills match your trap model, target flying pests, and replacement routine—not just the largest pack. My best overall pick is the Zevo Flying Insect Trap Refill Cartridges, 4 Count for shoppers who want brand-matched replacements, while the Raindot 40-Pack Sticky Refill Sheets stands out for compatible Safer Home traps and the RESCUE! Reusable Fly Trap Refill suits outdoor use. The main tradeoff is between convenient, device-specific cartridges and larger adhesive-sheet multipacks that may offer more replacements but require careful compatibility checks. Some options are meant for indoor light traps, while outdoor attractant refills serve a different purpose and are not interchangeable. Read on for the full comparison, selection criteria, and advice on choosing refills that fit your setup.

Key Takeaways
- Compatibility matters more than pack size: Raindot‘s 40 sheets are specifically listed for several Safer Home models, while M364-compatible cartridges such as Raindot‘s 16-pack and Dickinda‘s 10-pack serve a different trap family.
- Brand-matched refills simplify selection: Zevo, STEM, Ortho, and Safer Home options are easier to evaluate when the buyer already owns the corresponding device, but the products are not automatically interchangeable.
- Multipacks serve different replacement habits: The 24-board Dichroma pack and 40-sheet Raindot pack suit buyers who want a stock of adhesive replacements; smaller cartridge counts may be easier to store and manage.
- Indoor light-trap refills and outdoor fly-trap refills are separate categories: RESCUE! is explicitly for outdoor use, so it should not be treated as a replacement for an indoor glue board or light-trap cartridge.
- Compact and insecticide-free needs narrow the field: Zevo Compact targets compact traps for gnats and fruit flies, while STEM lists insecticide-free cartridges; buyers should choose around their device and stated use, not assume one refill fits every pest or trap.

More Details on Our Top Picks
Zevo Flying Insect Trap with 3 Refill Cartridges
Best for starting from scratch, this Zevo set includes the trap device as well as three refill cartridges, so it is a more complete purchase than refill-only options such as the Ortho Home Defense Max refills, which require a compatible trap already in hand. Its stated target is gnats, making it a focused choice for buyers dealing with that pest rather than seeking broad coverage across several insect types. The tradeoff is limited product detail: the information provided does not explain how the device operates or identify which replacement cartridges fit it. Compared with the Safer Home SH503 cards, whose SH502 compatibility is specified, this kit leaves more uncertainty for future replenishment. I would choose it when the included device is the priority, but look for clearer compatibility details if refill availability is your main concern.
Pros:- Includes one trap device and three refill cartridges
- Targets gnats
- Provides a ready-to-start option rather than a refill-only pack
Cons:- The description gives little detail about how the trap operates
- Compatibility and replacement options are not specified
- The stated target is narrower than products listing several insect types
Best for: Someone who needs a trap device and initial refills in one package, especially for a gnat problem.
Not ideal for: Owners of a specific plug-in trap who only need confirmed compatible refills, since compatibility details for this kit are limited.
- Brand:ZEVO
- Package contents:1 device and 3 refill cartridges
- Unit count:4
- Target species:Gnats
- Model number:Model 4
- Manufacturer part number:003
Our verdict“Choose this Zevo kit if you need both a device and gnat-focused refills, but favor a model-specific refill pack when compatibility certainty matters more.”
Safer Home Flying Insect Trap Glue Card Refills, 3-Pack
For Safer Home SH502 owners, these three StickyTech cards offer a clearly matched replacement rather than a trial-and-error fit. They are designed to capture fruit flies, gnats, moths, and other flying insects indoors, while keeping caught insects hidden from view—a practical difference from exposed adhesive sheets. Insert a card into the compatible trap and replace it when full or every 30 days. That schedule is clear, but it also means this small pack may not suit someone seeking a long supply. The Raindot 16-pack for M364, M364A, and Max offers more cards, but it does not fit the SH502; these Safer Home refills make more sense when exact model compatibility matters more than quantity. Skip them if you do not own the SH502.
Pros:- Specifically designed for the Safer Home SH502
- Targets fruit flies, gnats, moths, and other flying insects
- Captured insects are hidden from view
- Cards are simple to insert and replace
Cons:- Compatible only with the SH502 trap
- The three-card pack requires regular replenishment
- Cards should be replaced when full or every 30 days
Best for: Safer Home SH502 owners who want indoor refills for multiple flying-insect types and prefer captured insects kept out of view.
Not ideal for: People without the Safer Home SH502 plug-in trap, or buyers seeking a larger refill supply between replacements.
- Brand:Safer Home
- Model:SH503
- Quantity:3 glue cards
- Compatible device:Safer Home SH502 plug-in fly trap
- Technology:StickyTech adhesive cards
- Replacement interval:When full or every 30 days
- Intended use:Indoor flying insect control
Our verdict“Pick these cards if you own the SH502 and value a precise fit and concealed capture over a larger refill count.”
Raindot Flying Insect Trap Refills, 16-Pack, Compatible with M364, M364A, and Max
The broadest stated compatibility in this group makes Raindot a practical pick for households with an M364, M364A, or Max plug-in trap. The 16 sticky refills provide a deeper supply than the three-card Safer Home SH503 pack, while tool-free installation keeps changes simple. Their adhesive surface is intended for fruit flies, gnats, mosquitoes, and other flying insects indoors, giving this option a wider stated target range than the gnat-focused Zevo kit. The tradeoff is that “multi-model” still means only the listed models: these are not universal sheets, and they are designed for indoor use. I would choose Raindot when a compatible trap and frequent refill needs make pack size useful; buyers with an SH502 should instead select the specifically matched Safer Home cards.
Pros:- Compatible with three listed trap models
- Includes 16 sticky refills
- Targets fruit flies, gnats, mosquitoes, and other flying insects
- Installs without tools
Cons:- Compatibility is limited to M364, M364A, and Max models
- Designed for indoor use
- Requires a compatible trap and cannot serve as a standalone catcher
Best for: Owners of M364, M364A, or Max plug-in traps who want a sizable indoor refill supply for several flying-insect types.
Not ideal for: People with other trap models, including Safer Home SH502 owners, or anyone seeking a refill for outdoor use.
- Brand:Raindot
- Pack count:16
- Compatibility:M364, M364A, and Max plug-in insect traps
- Trap type:Sticky insect trap refill
- Intended use:Indoor flying insect trapping
- Color:White
- Item weight:1.6 ounces
- Item dimensions:1 x 1 x 1 inches
- Power source:Hand-powered
Our verdict“Choose Raindot for a substantial refill supply if your trap is one of the three listed models; otherwise, its compatibility range is a hard limit.”
Ortho Home Defense Max Indoor Flying Insect Trap Refills, 3 Cartridges
Up to three months of indoor protection is the clearest planning detail among these small refill packs, making Ortho a useful choice for buyers who want a stated coverage window. The three sticky cartridges target gnats, fruit flies, and house flies, a broader named set than the gnat-only Zevo kit. But this is not a complete trap: the compatible Ortho Home Defense Max plug-in device is sold separately. That limits its appeal to existing owners and makes it less suitable for someone starting from zero. Compared with the Safer Home SH503 cards, Ortho names house flies and provides an up-to-three-month claim, while Safer Home specifies replacement when full or every 30 days. Choose based on your trap model and preferred replacement guidance, not on refill count alone.
Pros:- Targets gnats, fruit flies, and house flies
- Three cartridges provide up to three months of protection when used as directed
- Designed for straightforward replacement
- The stated coverage period helps buyers plan changes
Cons:- Requires the separately sold Ortho Home Defense Max trap
- Compatible only with the specified device
- Cartridges still need periodic replacement
Best for: Owners of the Ortho Home Defense Max Flying Insect Trap who want three cartridges and a stated coverage period for common indoor flies.
Not ideal for: Buyers without the Ortho plug-in device, or those who need refills for a different trap model.
- Brand:Ortho
- Model number:4663505
- Part number:4663505
- Included:3 glue trap refill cartridges
- Coverage:Up to 3 months
- Compatible device:Ortho Home Defense Max Flying Insect Trap, sold separately
- Target insects:Gnats, fruit flies, and house flies
Our verdict“Choose Ortho if you already own its plug-in trap and value a stated coverage period; skip it if your device is another brand.”
Dickinda Flying Insect Trap Adhesive Refill Cartridges, 10-Pack, Compatible with M364 and M364A
Odorless adhesive is the distinguishing feature here, paired with ten cartridges for M364 and M364A traps. That makes Dickinda a more focused alternative to the Raindot 16-pack: Raindot covers three listed models and names a wider set of target insects, while Dickinda offers odorless refills for two specified models. Installation is straightforward—peel off the protective film and position the adhesive side facing the lamp—but these cartridges are replacements only, not standalone traps. Change one when its surface fills or its adhesion declines, so the pack count does not mean a fixed service period. I would pick this option when odorless adhesive and M364/M364A fit are the priorities; skip it if you use a Max model or want compatibility spelled out for more trap types.
Pros:- Odorless adhesive
- Includes 10 refill cartridges
- Designed for M364 and M364A traps
- Peel-and-insert installation requires no power source
Cons:- Cannot be used without a compatible trap
- Compatibility is limited to M364 and M364A
- Replacement timing depends on surface coverage or declining adhesion
Best for: M364 or M364A owners who prefer odorless adhesive refills and want a ten-cartridge supply.
Not ideal for: Owners of Max or other trap models, and anyone needing a standalone insect trap rather than replacement cartridges.
- Brand:Dickinda
- Quantity:10 refill cartridges
- Compatible models:M364 and M364A
- Adhesive:Odorless
- Dimensions:3.8 x 3.1 x 0.06 inches
- Color:Blue
- Power source:None
Our verdict“Choose Dickinda if you have an M364 or M364A and want odorless adhesive refills, but pick Raindot for a larger pack and an additional listed model.”
Dichroma Flying Insect Trap Replacement Glue Boards, 24-Pack
The broadest stated trap compatibility sets these boards apart: they fit BURLAN QH009A and Stingmon traps as well as Catchmaster Vector 9 and Wdoog models. That makes this a practical choice when you need refills for one of several specific devices, rather than the Safer Home-specific Raindot sheets. The 24-board pack also gives you more replacements on hand than JIMMY’S GARDEN’s 10-count listing, though JIMMY’S quantity information is inconsistent. Each Dichroma board is rated for up to two weeks, so frequent catches or heavier insect activity can use up the supply sooner than the pack count suggests. These are adhesive boards only: you need a compatible trap already, and they do not replace an outdoor bait-and-water system such as RESCUE!.
Pros:- 24 replacement boards provide a substantial on-hand supply
- Compatible with four named indoor trap model lines
- Targets mosquitoes, fruit flies, gnats, and other small insects
- No power source is needed for the boards
Cons:- Compatibility is limited to the listed trap models
- Each board is rated for no more than two weeks of use
- The trap device is not included
Best for: Owners of BURLAN QH009A, Stingmon, Catchmaster Vector 9, or Wdoog indoor traps who want a multi-board supply.
Not ideal for: People with Safer Home or Zevo traps, or anyone looking for a complete trap rather than replacement glue boards.
- Brand:Dichroma
- Quantity:24 glue boards
- Compatible models:BURLAN QH009A, Stingmon, Catchmaster Vector 9, Wdoog
- Target insects:Mosquitoes, fruit flies, gnats, and other small insects
- Maximum use per board:Up to 2 weeks
- Color:White
- Power source:None
Our verdict“Choose Dichroma if you own one of its listed trap models and want a larger refill supply across several compatible device lines.”
Raindot Fly Trap Sticky Refill Sheets, 40 Pack, Compatible with Safer Home SH502, SH503, 23005-06, and DT3005W
Forty sheets in one pack make Raindot the high-count pick for households already using one of its named Safer Home traps. Compared with the 24-board Dichroma pack, it offers more sheets, but that larger count does not make it a universal refill: compatibility is restricted to Safer Home SH502, SH503, 23005-06, and DT3005W. The adhesive backing allows tool-free replacement, which is useful when a sheet needs changing without extra parts or tools. Each sheet measures 3.81 by 3.14 inches, so check that format against your trap before buying. Like the other indoor glue-board options, these sheets are disposable and must be replaced after catching insects; they are not a substitute for RESCUE!’s outdoor water-activated fly bait.
Pros:- 40 sheets provide the largest stated sheet count among these indoor glue-board picks
- Adhesive backing supports tool-free replacement
- Targets flies, fruit flies, moths, and mosquitoes
- Sheet dimensions are provided for a fit check
Cons:- Compatible only with the specified Safer Home models
- Used sheets need to be replaced rather than reused
- The trap itself is not included
Best for: Safer Home SH502, SH503, 23005-06, or DT3005W owners who want a large supply of quick-change sheets.
Not ideal for: Owners of other trap brands or models, since the listed compatibility is limited to four Safer Home models.
- Brand:Raindot
- Quantity:40 sheets
- Compatible models:Safer Home SH502, SH503, 23005-06, DT3005W
- Sheet dimensions:3.81 x 3.14 inches
- Target insects:Flies, fruit flies, moths, and mosquitoes
- Color:White
- Power source:Manual
- Model number:N-002
Our verdict“Pick Raindot if you have a listed Safer Home trap and want a large stock of simple, tool-free replacement sheets.”
JIMMY’S GARDEN Flying Insect Trap Refill Cartridges, 10 Count
Peel-and-insert replacement is the main draw here: the adhesive cartridge is designed to be swapped without handling a loose glue board. It targets a broad mix of indoor flyers, including flies, fruit flies, gnats, moths, and mosquitoes, giving it wider stated coverage than RESCUE!’s refill, which is for flies and outdoor use. The tradeoff is fit certainty. JIMMY’S GARDEN says these work with compatible plug-in traps but does not name specific models, while Zevo explicitly lists its standard and MAX devices. There is also a quantity discrepancy: the title says 10 count, but the specs say 8 pieces. I would verify the delivered quantity before relying on this as a planned supply, and skip it if your trap’s compatibility is not confirmed.
Pros:- Adhesive cartridges target several kinds of flying insects
- Replacement process uses a peel-off protective layer and insertion
- Intended for indoor use across multiple spaces
- Manual cartridges do not need their own power source
Cons:- Specific compatible trap models are not named
- Quantity is inconsistent between the 10-count title and 8-piece specification
- The compatible trap device is not included
Best for: Indoor plug-in trap owners whose device is confirmed compatible and who prefer inserting a cartridge over handling a loose sheet.
Not ideal for: Buyers who need a clearly specified trap fit or a dependable stated quantity, given the generic compatibility and conflicting count details.
- Brand:JIMMY’S GARDEN
- Quantity stated:10 count in title; 8 pieces in specifications
- Compatibility:Compatible plug-in flying insect trap devices; specific models not listed
- Capture method:Adhesive sticky surface
- Intended use:Indoor
- Item dimensions:1.3 x 0.37 x 5.8 inches
- Color:Gray
- Model number:ZCB015
Our verdict“Consider JIMMY’S GARDEN if your plug-in trap is confirmed compatible and cartridge-style changes matter more than precise count information.”
RESCUE! Reusable Fly Trap Refill – Outdoor Use – 6 Pack
A water-soluble attractant pouch gives RESCUE! a different job from the indoor adhesive refills in this roundup. Drop a pouch into a compatible RESCUE! Reusable Fly Trap, add water, and hang it outdoors to target house, blow, bottle, and other nuisance flies. Unlike the Zevo adhesive cartridges, this is not designed to catch insects discreetly inside the home; it is meant to draw flies to an outdoor trap. Placement matters: the instructions call for hanging it at least 20 feet from living areas, and the product is for outdoor use only. That distance and the scent may make it a poor fit for small patios or spots close to doors. It also requires the matching reusable trap, which is not included with the refill pack.
Pros:- Targets several common nuisance and filth fly types
- Water-soluble pouch is used by adding water to the trap
- Six refills are included
- Made in the USA
Cons:- For outdoor use only
- Must be placed at least 20 feet from living areas due to scent
- Requires a compatible RESCUE! reusable trap
Best for: People with a RESCUE! Reusable Fly Trap who need an outdoor refill for nuisance and filth flies away from living areas.
Not ideal for: Indoor users, owners of adhesive-light traps, or anyone without room to place a scented fly trap at least 20 feet from living areas.
- Brand:RESCUE!
- Model number:FTA-DB12
- Quantity:6 refills
- Target species:House, cluster, blow, bottle, flesh, and other flies
- Use:Outdoor; hang at least 20 feet from living areas
- Trap compatibility:RESCUE! Reusable Fly Traps
- Style:Hanging
- Origin:Made in the USA
Our verdict“Choose RESCUE! for outdoor fly control with its matching reusable trap, not as a refill for an indoor light-and-glue device.”
Zevo Flying Insect Trap Refill Cartridges, 4 Count
Hidden adhesive capture makes Zevo the clearest choice here for indoor users who want trapped insects kept out of view. These cartridges work with standard Zevo and Zevo MAX traps, whose blue and UV light draws flies, fruit flies, gnats, and other flying insects onto the adhesive surface. Compared with the broad but model-specific sheets from Raindot, Zevo provides a straightforward fit for two named Zevo device types; it will not fit the other trap brands in this group. The odor-free, dye-free design supports discreet use, while the four-cartridge pack is smaller than Raindot’s 40-sheet supply or Dichroma’s 24 boards. Cartridges need replacement once full, and the lighted trap device is required but not included.
Pros:- Compatible with standard Zevo and Zevo MAX traps
- Hidden adhesive surface keeps captured insects out of view
- Odor-free and made without added dyes
- Designed for continuous day-and-night use in the compatible trap
Cons:- Requires a compatible Zevo trap, which is not included
- Four cartridges provide fewer replacements than the Raindot and Dichroma packs
- Cartridges must be replaced when full
Best for: Owners of standard Zevo or Zevo MAX indoor traps who want used insects concealed on an adhesive cartridge.
Not ideal for: People without a compatible Zevo device or buyers seeking a high-count stock of replacement boards or sheets.
- Brand:ZEVO
- Quantity:4 cartridges
- Compatible devices:Zevo MAX and standard Zevo flying insect traps
- Target insects:Flies, fruit flies, gnats, and other flying insects
- Material:Plastic
- Color:White
- Model number:Model 4
- Manufacturer part number:ZEV-018568
Our verdict“Choose Zevo if you own a compatible Zevo light trap and value concealed, odor-free indoor capture over a larger refill quantity.”
Shootingstar 40-Pack Replacement Glue Boards for Safer Home Indoor Fly Traps
Forty boards make this the strongest pick for households that go through flat refills often. Each paper board is rated for up to three weeks, and compatibility covers specific Safer Home and DynaTrap indoor traps, including the SH502, SH503, DT3005W, and DOT 23005-06. Compared with the Raindot 40-pack in this roundup, the main distinction is brand and stated compatibility; buyers should match the model number rather than assume the boards interchange. These boards target mosquitoes, moths, flies, and other small flying pests, but they are replacement inserts, not a standalone trap. You’ll also need to peel away the plastic cover and fit each board into the device. This is a practical stock-up option, though it is a poor fit for anyone with a different trap system.
Pros:- Includes 40 replacement boards
- Compatible with four specified Safer Home and DynaTrap models
- Each board is rated for use up to three weeks
- Targets several small flying pests indoors
Cons:- Compatibility is limited to the listed trap models
- Requires removing the protective cover and inserting each board
- Does not include a trap
Best for: Owners of a listed Safer Home or DynaTrap model who want a large supply of indoor glue-board refills.
Not ideal for: People with Zevo, STEM, or M364-style cartridge traps, or buyers who want refills that need no manual insertion.
- Brand:Shootingstar
- Quantity:40 boards
- Material:Paper
- Compatible models:Safer Home SH502, SH503; DynaTrap DT3005W, DOT 23005-06
- Target pests:Flies, mosquitoes, moths, and other small flying pests
- Recommended use:Indoor
- Use duration:Up to 3 weeks per board
- Item weight:0.37 kg
Our verdict“Choose this pack if you own a compatible Safer Home or DynaTrap unit and want a substantial reserve of paper boards.”
STEM Flying Insect Light Trap Refill Cartridges, 8 Count
This eight-cartridge pack is the larger of the two STEM options here, making it a sensible choice for existing STEM Light Trap owners who prefer to keep replacements on hand. Like the six-count STEM refill, it uses insecticide-free, odorless sticky cartridges for indoor use and targets mosquitoes, gnats, moths, house flies, and fruit flies. The extra two cartridges make this the better fit for a household expecting regular use; they do not change the device compatibility or remove the need to replace cartridges after they catch insects. Compared with the Zevo Compact refills, STEM’s stated pest list includes mosquitoes, while Zevo is designed for its own Plant and Compact traps. The limitation is firm: these cartridges are for the STEM Light Trap, not a general-purpose refill.
Pros:- Eight cartridges per pack
- Insecticide-free and odorless
- Targets mosquitoes, gnats, moths, house flies, and fruit flies
- Designed for easy replacement in the STEM Light Trap
Cons:- Compatible only with the STEM Light Trap
- Cartridges must be replaced after use
- Effectiveness depends on use as directed
Best for: STEM Light Trap owners who want a larger supply of odorless, insecticide-free cartridges for indoor use.
Not ideal for: Buyers without a STEM Light Trap or anyone seeking refill sheets that fit a different trap brand.
- Brand:STEM
- Compatible device:STEM Light Trap
- Quantity:8 cartridges
- Pest-control method:Sticky refill cartridges
- Insecticide-free:Yes
- Target insects:Mosquitoes, gnats, moths, house flies, and fruit flies
- Intended use:Indoor
Our verdict“Pick the eight-count STEM pack over the six-count version if you already own the device and want more replacement cartridges in reserve.”
STEM Flying Insect Light Trap Refill Cartridges, Insecticide-Free, 6 Count
For a STEM Light Trap owner who wants a discreet, odorless refill, this six-count pack keeps the choice straightforward. Its sticky cartridges are described as insecticide-free and designed to catch mosquitoes, gnats, moths, house flies, and fruit flies when used as directed. That makes it a more clearly specified option than the Husaco six-cartridge refill, whose compatible trap details are limited. The tradeoff is that STEM’s cartridges only fit the STEM Light Trap, so the broader pest list does not mean broader device compatibility. Compared with the eight-count STEM pack, this version provides fewer replacements; choose it when six cartridges suit your expected use rather than paying for a larger stash in the same trap system. It is not a standalone trap or a universal sticky insert.
Pros:- Insecticide-free sticky cartridges
- Odorless and discreet for indoor settings
- Designed to capture several common flying insects
- Clearly identified compatibility with the STEM Light Trap
Cons:- Requires a compatible STEM Light Trap
- Six cartridges provide fewer replacements than the eight-count STEM pack
- Cartridges need replacement after use
Best for: STEM Light Trap owners who prioritize odorless, insecticide-free indoor refills and need a six-cartridge supply.
Not ideal for: Shoppers with another brand of trap, or STEM owners who want the larger eight-cartridge pack.
- Brand:STEM
- Compatible with:STEM Light Trap
- Quantity:6 cartridges
- Pest-control method:Sticky refill cartridges with light trap
- Insecticide-free:Yes
- Target insects:Mosquitoes, gnats, moths, house flies, and fruit flies
- Manufacturer:SC Johnson
- UPC:197981005138
Our verdict“Choose this six-pack for a compatible STEM trap when odorless, insecticide-free refills matter more than getting the larger pack.”
Zevo Compact Flying Insect Trap Refills for Gnats and Fruit Flies, 6 Count
These six covered cartridges suit Zevo Plant and Zevo Compact owners who want to remove captured insects without handling the sticky surface. The covered design keeps the catch out of sight, a useful distinction from the exposed paper boards in the Shootingstar 40-pack. Zevo’s blue and UV light trap is aimed at flies, fruit flies, and fungus gnats, so this refill choice is especially relevant near plants, kitchens, and other indoor trouble spots. Its main limitation is placement: the product notes that competing light can reduce effectiveness, which may restrict where the trap works well. The six-cartridge count also offers less stock than the large Shootingstar board pack, but these are different formats and neither fits the other’s devices. Match the refill to the exact Zevo model.
Pros:- Covered design keeps trapped insects out of sight
- No-touch cartridge replacement
- Uses no sprays or insecticides
- Designed for Zevo Plant and Zevo Compact traps
Cons:- Compatible only with Zevo Plant and Zevo Compact devices
- Competing light sources can reduce effectiveness
- Six cartridges may be a limited supply for frequent replacement
Best for: Zevo Plant or Zevo Compact owners who want hidden catches and no-touch cartridge changes near plants or kitchens.
Not ideal for: People with other trap brands, or households that cannot place the trap away from competing light sources.
- Brand:ZEVO
- Quantity:6 cartridges
- Compatible devices:Zevo Plant and Zevo Compact
- Target species:Flies, fruit flies, gnats, and other flying insects
- Trap type:Blue and UV light
- Power source:Electric (trap)
- Material:Plastic
- Item weight:2.88 ounces
Our verdict“Choose these Zevo refills if hidden catches and no-touch changes matter and you own one of the two specified trap models.”
Husaco Flying Insect Trap Refills, 6 Cartridges
Husaco offers a six-cartridge set for buyers who already know their trap takes this refill format and want replacements aimed at flies, fruit flies, gnats, and moths. Its listed dimensions—5.5 x 3.5 x 0.1 inches—make the cartridge size clear, while the lack of a power source confirms these are passive refills rather than a complete trap. Compared with the Zevo Compact refills, Husaco does not specify a compatible device family or describe a covered, no-touch design. That uncertainty is the deciding drawback: the product data says “compatible flying insect traps” but does not identify models. I would verify fit with the trap maker before ordering. If model-specific compatibility matters, the named STEM or Zevo options are easier to match confidently.
Pros:- Six cartridges included
- Targets flies, fruit flies, gnats, and moths
- Specified dimensions help buyers check physical fit
- No power source is needed for the refill itself
Cons:- Compatible trap models are not identified
- The refill pack does not include a trap
- No use duration or replacement interval is provided
Best for: Owners of a flying insect trap who can confirm that its cartridge dimensions and fit match this Husaco refill.
Not ideal for: First-time refill buyers or anyone unable to verify compatibility, since specific supported trap models are not listed.

Our verdict“Consider Husaco only if you can confirm cartridge compatibility with your existing trap, since its model guidance is less specific than Zevo’s or STEM’s.”
How We Picked
I compared the 15 options by the factors that determine whether a refill will be useful after purchase: listed device compatibility, refill format, stated use, and replacement quantity. I gave priority to clear model or brand matching because a large pack has little value if its adhesive boards or cartridges do not fit the trap. I also separated indoor light-trap refills from outdoor fly-trap refills rather than ranking unlike products as though they served the same job.
The order favors options with a clear role and a practical match for a recognizable buyer need. Brand-specific cartridges and established device families lead for shoppers seeking a straightforward replacement; compatible multipacks rank well for buyers who value having more boards on hand, provided the listed fit matches their trap. Compact, insecticide-free, and outdoor-focused picks earn distinct places for their narrower use cases, while generic or less-defined compatibility makes a product harder to recommend broadly. Product claims and pack counts are treated as stated; I do not assume unlisted performance, lifespan, or fit.
Factors to Consider When Choosing Best Flying Insect Trap Refills
Before choosing a refill, start with the trap you own and the space where it operates. Fit, placement, and replacement needs shape the decision more than a high sheet count alone. These broader checks can help prevent a refill purchase that is inconvenient or incompatible.
Match the Refill to the Exact Trap
Identify the trap’s brand and model before comparing refill packs; product names that share terms such as “flying insect” do not establish compatibility. Check the device label, manual, or existing refill for a model number, then compare it with the refill’s listed compatible models. A close visual match is not enough because cartridges may differ in shape, attachment points, or dimensions. If a listing names several models, confirm that yours appears in that list rather than relying on a broad brand name. When the model is uncertain, choosing the original device brand is often a simpler path than taking a chance on a larger third-party pack.
Separate Indoor Light Traps From Outdoor Fly Traps
Refills are designed around different trap systems, so the intended setting is a functional distinction, not just packaging language. Indoor light traps commonly use adhesive cards or cartridges positioned inside a device, while an outdoor reusable fly trap may use a different refill approach. Do not substitute an outdoor product for an indoor cartridge unless the manufacturer lists that use and fit. Also think about where a trap can be placed: an indoor device needs an outlet or suitable surface, while outdoor systems may need a location away from doors and seating. Choosing the right setting first helps avoid judging a refill by features meant for another kind of trap.
Choose Pack Size Around Your Replacement Routine
A larger multipack can reduce how often you reorder, but it only helps if you have a compatible device and a place to store unused boards. Estimate how many traps you operate and how frequently you expect to replace a refill, using the device maker’s instructions rather than assuming a fixed lifespan. Adhesive surfaces may need attention sooner in a busy area or when they collect debris, while a lightly used trap may not justify a large stock. Smaller packs can suit first-time buyers who want to confirm fit before committing to more. Treat pack count as convenience and inventory, not proof of stronger attraction or longer service.
Consider the Pest and the Trap’s Job
Refills do not all target the same flying-insect problem, and a trap designed around small indoor pests may not serve as an all-purpose fly solution. Check which insects the device and refill name explicitly address, then pair that with where the insects appear. If the issue is concentrated around fruit, drains, plants, or outdoor waste, the source may need attention alongside trapping. A refill can collect insects near the device but cannot correct conditions that keep drawing them in. Avoid selecting a pack solely because its label says “fly” or “insect”; look for a match between the listed target, the trap, and your setting.
Weigh Brand-Matched Convenience Against Third-Party Packs
Original-brand refills can make replacement selection more straightforward because they are sold for a known device family. Third-party compatible packs may provide more adhesive pieces or a different pack size, but buyers take on the work of checking model fit and refill dimensions. A low-friction purchase is often worth more than spare boards that sit unused or fail to attach properly. Compare the exact model list, cartridge or sheet format, and quantity before choosing between branded and compatible options. If compatibility details are vague, favor a clearly listed fit over an appealing count.
Check Storage and Handling Needs
Refills are consumables, so storage matters when buying several at once. Keep unused adhesive surfaces protected from dust, heat, and accidental contact, following any package directions; exposed sticky areas can become less useful before they reach the trap. Consider whether you have room to store a large carton and whether each refill is individually protected. For homes with children or pets, follow the device and refill instructions for placement and handling, and keep replacement parts out of reach. A practical pack is one you can store cleanly and use as intended, not simply the one with the most pieces.
Frequently Asked Questions
Can I use a third-party refill in my Zevo or Safer Home trap?
Only if the refill listing names your exact trap model or the manufacturer confirms compatibility. Similar-looking adhesive cards can differ in size, mounting points, or cartridge shape, so appearance alone is not a reliable fit check. Compare the model number on your device with the compatible-model list before ordering. If the listing does not identify your model, a brand-matched refill is the less uncertain choice. Keep the packaging until you confirm that the refill seats correctly in the trap.
Are 40- or 24-count glue-board packs a better choice than smaller cartridge packs?
A larger board pack makes sense when you already own a compatible trap and expect to replace boards regularly. It is not automatically the better buy if your device uses cartridges, if the boards do not fit, or if you cannot store the extras cleanly. Smaller packs can be a sensible way to verify fit and replacement habits before keeping a larger supply at home. Compare the refill format as well as the number of pieces. The best pack size is the one you can use before storage or compatibility becomes a problem.
Do indoor flying insect trap refills work in outdoor fly traps?
Usually, no: indoor light-trap cartridges and outdoor reusable fly-trap refills are built for different devices and settings. The RESCUE! option in this roundup is labeled for outdoor use, while the Zevo, STEM, Ortho, and Safer Home products are associated with indoor trap systems. Follow the product’s stated use rather than trying to adapt one refill to another trap. Outdoor placement can also affect where insects gather, so keep traps away from spots where people eat or sit when the instructions call for that separation. If you need both indoor and outdoor control, choose a refill intended for each device.
Should I choose an insecticide-free refill if I have children or pets?
An insecticide-free claim can help narrow the options, and STEM explicitly describes its light-trap cartridges that way. It does not mean every part of the trap is risk-free or that placement and handling instructions can be ignored. Check the full product and device directions, including how to install and dispose of adhesive boards. Position the trap where children and pets cannot interfere with it, especially if it uses an electrical device or exposed adhesive. If safety details are unclear, consult the manufacturer before use.
How can I tell whether a refill pack is right for gnats or fruit flies?
Start with the trap model, then check whether the refill and device explicitly name the pest you are trying to catch. Zevo’s compact refill is labeled for gnats and fruit flies, but that does not make it a universal fit for every compact trap. Small flying insects can also come from different sources, so placement and removing the source may matter as much as the refill. Use the device instructions to place the trap near the activity without blocking its intended operation. If the refill does not list your trap model or target use, do not infer suitability from the product title alone.
Conclusion
For most buyers who already own the matching device, my best overall choice is the Zevo Flying Insect Trap Refill Cartridges, 4 Count, a straightforward brand-matched option. The best value for frequent replacement is the Raindot 40-Pack Sticky Refill Sheets when the buyer has one of its listed Safer Home models; the high count is useful only with a confirmed fit. For a best premium-style brand-matched pick, consider the STEM Flying Insect Light Trap Refill Cartridges, 8 Count if you own a compatible STEM trap and want a larger brand-specific supply. Beginners should start with a refill explicitly made for their trap—Zevo, STEM, Ortho, or Safer Home—rather than guessing at third-party compatibility. For specific needs, choose Zevo Compact for a compatible trap targeting gnats and fruit flies, STEM’s insecticide-free cartridges if that stated feature matters, or RESCUE! for its labeled outdoor use. If none of those match your device, check the model number first; fit is the deciding factor across this lineup.
