The Victor M327 roach and insect traps are prebaited with Victor’s highly effective roach pheromone attractant and a food scent to lure roaches in. Each case comes with 150 larger traps that can be split along a perforated edge to create 300 smaller traps. The traps can be mounted on almost any surface. Victor M327 Roach Pheromone and Insect Monitor Traps contain no poisons and will not harm children or pets. These traps are perfect not just for roach control, but to monitor early warning signs of a potential german roach problem in apartments, houses, etc. (in other words, these traps will catch the very first roaches in a premature infestation, allowing you to take action early, rather than later). A must have with any roach control program.
