Do you suspect you have an insect infestation? Let Catchmaster do the detective work for you! Catchmaster Insect Traps and Monitors are glue boards that use a food grade molasses to attract, catch, and monitor insects. These pre-baited traps can be used to determine the species, the location, and the severity of insect infestations. These insect traps and monitors can be used anywhere, and the adhesive backing ensures that the product will stay exactly where you put it, including on walls, baseboards, behind appliances or any other area where insects might crawl or where you suspect insect activity.
