Pro-Pest R.T.U. Roach & Crawling Insect Traps are pre-baited with an enticing food lure in the glue. Simple to use, just remove the release paper, fold in to rectangular trap and it’s ready. A discreet and slim design allows the traps to fit under equipment, under & behind furniture, in cabinets, along baseboards etc. They have a printed black interior that is designed to take advantage of the fact that cockroaches and other insects prefer dark places for harborage. Both ends of the trap have 45-degree sloped entry ramps. The forward momentum of the cockroach takes them over the slopes and onto the glue surface where they cannot escape. Wings over center window entries keep out dust and provide air flow to disperse attractant.
