Trapper Monitor & Insect Trap is a non-poisonous glue trap that captures and monitors insects. Use it to accurately determine the location, species and severity of insect infestations. The sturdy, 7×3.5-in. cardboard trap can be used whole as a large trap, or separated along perforated lines into three smaller traps. Its adhesive backing sticks to nearly any clean surface. The trap contains space to record the date and location of use. For cockroaches, use the trap with scented Trapper Roach Attractant Tablets. These non-poisonous pellets attract roaches to the glue.
