A spot-on pesticidal composition consisting of about 1% to about 20% (w/w) fipronil, about 1% to about 20% (w/w) etofenprox, about 1% to about 20% (w/w) insect growth regulator, 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.
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 consisting of about 1% to about 20% (w/w) fipronil, about 1% to about 20% (w/w) etofenprox, about 1% to about 20% (w/w) insect growth regulator, and 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, etofenprox, and insect growth regulator 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.
