Protect yourself from an array of creepy crawlers, including the deadly ‘big 3’- black widow, hobo spider & brown recluse- with terro’s non-toxic spider & insect traps. Each package includes four ready-to-use glue traps. The spider traps can be folded to prevent children & 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 & kill a large# of spiders & other crawling insects. Pesticide free & easy-to-use, spiders, scorpions, ants, cockroaches, crickets & other crawling insects are captured by the trap’s sticky surface where they get stuck & die. For best results, replace the spider traps every three months or when the trap becomes full of spiders & insects.
