The RESCUE! Spider Trap catches a variety of biting and poisonous spiders common in the home, including: black widow spiders, brown recluse spiders, sac spiders, hobo spiders, jumping spiders and wolf spiders.It works with four entrances and hundreds of glue dots, allowing spiders to travel to the interior of the trap instead of merely congregating on the edges -- allowing many more to be caught. Spiders cannot remove themselves from the glue and eventually expire. And with two sides of glue, a quick flip of the trap keeps you in the spider-catching business. Rescue Spider Trap, 3 pack: Exclusive glue dot pattern allows more spiders to be caught Decorative plastic shell Thin shape allows placement in narrow spaces Sturdy plastic shell withstands crushing or bending Ready to use; nothing to assemble Two sides of glue for double the use Attractive, yet inconspicuous
