Abstract: A method is set forth of controlling pests such as termites. The method comprises mixing a residual pesticide with a foaming agent, water and air to produce a temporary non-solidifying pesticidal foam having an expansion ratio, defined as the ratio of the final foam volume to the sum of the volumes of the pesticide, the foaming agent and the water, of between 20 to 1 and 5 to 1. The foam is applied at a locus whereby it contacts a surface which defines the locus, and thereafter deposits the pesticide on the surface and dissipates, so as to provide residual pesticidal action on the surface.
