<p>A composition for the control of insects in the form of a substantially anhydrous gel comprises a pyrethrin or pyrethroid active ingredient, a solvent carrier, a carboxyvinyl polymer and a neutralizing agent for the carboxyvinyl polymer. Preferably, the gel evaporates to leave a film of material with insecticidal and insect-repelling properties. The gel has sufficient viscosity that it may be applied to precise locations on the skin.</p> |
