How Does Ortho Home Defense Work Against Earwigs?
Ortho Home Defense contains active ingredients such as bifenthrin and deltamethrin, which are synthetic pyrethroids. These compounds disrupt the nervous system of insects, leading to paralysis and death. When sprayed in areas where earwigs are likely to enter, such as doorways, windowsills, and along the foundation of your home, it creates a protective barrier that prevents these pests from invading.
