CimeXa Insecticide dust is labeled for control of bedbugs, fleas, ticks, lice, roaches, ants, firebrats, silverfish, spiders and mites. It may also be used for the prevention and treatment of drywood termites. The broad label allows the product to be used to treat cracks, crevices, voids, mattresses, carpets, pet rest areas, attics and many other areas. The engineered silica-based dust has exceptional absorption of water(in liquid form) and oil, destroying the insect's waxy cuticle, causing rapid dehydration and death. The standard usage rate is 2oz per 100 square feet.
