The Exacticide Bed Bug carpet treatment applicator was designed to push CimeXa dust deep down into the carpet fibers for the most effective bed bug elimination. Bed Bugs migrate across carpets to beds and furniture in search of a blood meal. CimeXa Dust is an effective bed bug carpet treatment, as it stops foraging Bed Bugs in their tracks. See The Entomologist at University of Kentucky test results in PCT Mag, Aug 2014. (Exacticide is needed but not included with this item.)
