Aerosol stable foam insecticide bait composition suitable for crawling insects which comprises a film forming edible foam carrier, an attractant suitable to be carried by the foam and a toxicant which should be non-repellent, is disclosed. The foam is comprised of a film forming water soluble polymer which contains an emulsifier. The composition is formulated so that it can be pressurized within a container. Upon release into a crevice, the foam expands and coats the entire intersurface, then contracts upon drying to present a passageway for the insects to contact the toxicant. The film forming polymer may be of an edible nature such that social insects such as ants will carry away pieces of the edible foam carrier into their nests where it will be fed to others within the colony thereby controlling or eradicating the colony. |
