Protect yourself from an array of creepy crawlers, including the Big 3 - brown recluse, black widow and hobo spiders - with non-toxic TERRO spider and insect traps. 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, ants, cockroaches, crickets and other crawling insects are captured by the sticky surface on the TERRO spider and insect trap where they get stuck and die.
