Black Flag Ant & Roach Killing Chalk forms barriers which insects must crawl over to enter the home or to get to and from food and water. These barriers are formed by drawing treatment bands around such areas as baseboards, door frames, underside of shelving and cabinet drawers.
Controls ants and roaches for up to 8 weeks! It is odorless and does not stain. Each chalk provides protection that you can see where you applied – ants and roaches pick up tiny particles and die in minutes. Patented chalk dispenser is child-resistant and keeps chalk away from the user’s hands.
Great for treating baseboards, moldings, around plumbing, dark corners in closets, around doors, ventilators, windows and other openings. Also treat undersides of work tables, storage shelving, floor drains, garbage rooms, locker rooms, switch boxes and the back of switch plates.
