Abstract
A spot-on pesticide composition for animals, specifically mammals, including dogs and cats, which composition comprises a combination of fipronil and etofenprox as the active components, in doses and proportions which are parasiticidally effective against a variety of insects and pests, and in a formulation which is convenient for local application to the mammal's skin, preferably localized over a small surface area.

A spot-on pesticidal composition consisting of about 1% to about 20% (w/w) fipronil, about 1% to about 20% (w/w) etofenprox, about 55% to about 80% (w/w) of an organic solvent selected from the group consisting of acetyltributyl citrate, fatty acid esters, diisobutyl adipate, acetone, acetonitrile, benzyl alcohol, butyl diglycol, dimethylacetamide, dimethylformamide, dipropylene glycol n-butyl ether, ethanol, isopropanol, methanol, ethylene glycol monoethyl ether, ethylene glycol monomethyl ether, diethylene glycol monoethyl ether, monomethylacetamide, dipropylene glycol monomethyl ether, liquid polyoxyethylene glycols, propylene glycol, 2-pyrrolidones, N-methylpyrrolidone, ethylene glycol, diethyl phthalate, and ethoxydiglycol, and optionally 0% to about 10% (w/w) of an antioxidant.
A method of killing insect and pest pupae and adults on an animal, which method comprises:
- administering a localized cutaneous application between the shoulders of the animal, a spot-on composition comprising about 1% to about 20% (w/w) fipronil, about 1% to about 20% (w/w) etofenprox, about 55% to about 80% (w/w) organic solvent selected from the group consisting of acetyltributyl citrate, fatty acid esters, diisobutyl adipate, acetone, acetonitrile, benzyl alcohol, butyl diglycol, dimethylacetamide, dimethylformamide, dipropylene glycol n-butyl ether, ethanol, isopropanol, methanol, ethylene glycol monoethyl ether, ethylene glycol monomethyl ether, diethylene glycol monoethyl ether, monomethylacetamide, dipropylene glycol monomethyl ether, liquid polyoxyethylene glycols, propylene glycol, 2-pyrrolidones, N-methylpyrrolidone, ethylene glycol, diethyl phthalate, and ethoxydiglycol, and optionally 0% to about 10% (w/w) of an antioxidant, wherein the composition is administered in a volume sufficient to deliver a dosage of fipronil and etofenprox ranging from about 0.1 mg/kg to about 40 mg/kg of animal weight, and wherein at least 90% efficacy against insect and pest pupae is achieved.
