Turn to TERRO Roach Magnet to trap roaches, spiders, scorpions and other insects. With the TERRO Roach Magnet, you’ll be able to defend your property thanks to the Exclusive Pheromone Technology infused in the trap glue. Cockroaches are attracted to these pheromones, which draws these repulsive insects into the trap where they become stuck and die. Each package includes 12 TERRO Roach Magnet traps.
