Protect yourself from an array of creepy crawlers, including the deadly “Big 3”- black widow, hobo spider and brown recluse- with TERRO’s non-toxic spider and insect traps. Each package includes four ready-to-use glue traps. The spider traps can be folded to prevent children and pets from coming in contact with the non-toxic sticky surface, or they may be used unfolded to lie flat. TERRO Spider & Insect Traps are an excellent way to capture and kill a large number of spiders and other crawling insects. Pesticide free and easy-to-use, spiders, scorpions, ants, cockroaches, crickets and other crawling insects are captured by the trap’s sticky surface where they get stuck and die. For best results, replace the spider traps every three months or when the trap becomes full of spiders and insects.
