Whenever we try and control things like roaches many times we reach for chemicals. Dust, bait, sprays, fogs, you name it. But try adding something like Cryonite and a vacuum from Atrix to your tool box. A dynamic duo for sure, The Batman and Robin of pest control tools. This pair will insure success and greatly reduce the amount of toxicant you place into a clients home or business. BTW that suit is from Mattress Safe and is the best thing to be wearing in bug infested situations. Keeps you from bringing home more than just the bacon.
