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 are ready to use either flat or folded, and can fold up to prevent children and pets from touching the sticky surface. Use around the home against baseboards, in corners, behind doors, and underneath furniture.
