Pest Control Products for Spider Elimination
Spiders (including Black Widow, Brown Recluse and others) are more difficult to kill with pesticides than other household pests. Care should be taken when choosing a residual insecticide spray and insecticide dust in pest control programs targeting spiders. Insecticide sprays listed can be used for indoor and outdoor general purpose household pest control. Dust and aerosols are mainly used for cracks and crevices (places where spiders and other bugs hide or enter a structure.) Crack and crevice work is very important when eliminating spiders.
Products can be purchased individually:
