Black Flag Ant and Roach Killing Chalk, properly applied, forms barriers over which insects must crawl to enter the facility or to get to and from food and water. These barriers are formed by drawing treatment bands. These treatment bands must intersect without breaks or gaps for complete and effective barriers. A single band or bands, the width of the chalk, is effective. Wider bands are unnecessary.
