Abstract
Crawling insects are caused to abandon sites they have infested or prevented from infesting other sites by preparing dispersions from selected minus 10 micron particles and forming a film on the surface to be protected. Different insects can selectively be controlled by adjustment of the particle sizes in the dispersion.
