Control Methods

Contact-kill insecticides like pyrethrin, insecticidal soap, and spinosad provide immediate pest knockdown but require direct contact and thorough coverage.

Insect growth regulators like neem oil's azadirachtin prevent insects from molting and reproducing — slower than contact kill but with longer-lasting suppression.

Smothering insecticides block insect breathing pores with oils or soaps. Physical mode of action means resistance cannot develop.

Physical barriers prevent pest access without chemicals — row covers, kaolin clay particle film, and diatomaceous earth all work through obstruction rather than toxicity.

Biological controls use living organisms — predatory insects, parasitic wasps, fungi, and bacteria — to suppress pest populations. They are self-sustaining once established.

Some DIY pest remedies work well (neem soap spray, castile soap) while others are mostly myths (garlic pepper spray, coffee grounds). Know the difference before…
