Great defense option against cockroaches under appliances, sinks, furniture, around drains, along closet shelves, ledges, cabinets, drawers, cracks, & crevices. A non-repellent powder roaches do not avoid. When they get near it, the electro-static charged powder clings & is carted back to their nests. One pound of Roach Powder treats up to 2,000 square feet. For best results, the powder should be used in every room of a building. Simply sprinkle the powder over the desired area.
