To maximize effectiveness, you should reapply after heavy rain or if you notice pests returning. Regular application helps maintain the insecticide’s protective barrier and keeps your garden healthier.
Can Soap Sprays Harm Beneficial Insects in My Garden?
Imagine your garden as a delicate symphony, where beneficial insects are the silent conductors. Soap spray impact can sometimes harm these helpful creatures if used excessively or incorrectly.
