No one wants roaches in their home or business. Turn to TERRO Roach Magnet to trap these repulsive insects. With the TERRO Roach Magnet, you'll be able to defend your property from roaches and several other insects, including ants, centipedes and others. These traps will also capture spiders and scorpions, too. The TERRO Roach Magnet uses Exclusive Pheromone Technology that is included in these traps. Cockroaches are attracted to these pheromones, which draws them into the trap where they become stuck and die. Each package includes 12 TERRO Roach Magnet traps, so you can achieve maximum coverage around your home or business. When the trap gets full of insects and spiders, throw it away and set another.
