Abstract: The invention provides an ectoparasiticidal formulation which comprises an ectoparasiticidal agent, preferably the pyrethroid permethrin, as the pesticidally-active ingredient, together with a crystallization inhibitor selected from the group consisting of alkyl-substituted pyrrolidones, and optionally, one or more organic solvents and/or co-solvents. Preferably, the crystallization inhibitor is N-octyl pyrrolidone, and the organic solvent, if present, preferably comprises diethylene glycol monoethyl ether. The ectoparasiticidal formulation surprisingly yields a significantly enhanced speed of kill. Methods for manufacturing the formulation, as well as methods for treating animals infested with ectoparasites, are also disclosed.

Abstract: A method of and a composition for treating a parasitic infestation in an animal and/or its environment is provided. The method includes providing an ectoparasitcidal formulation which comprises two or more IGRs, in which the IGRs may be selected from the same IGR class or from different IGR classes (excluding two or more juvenile hormone mimic IGRs selected from S-methoprene, hydroprene and pyriproxyfen) and regardless of whether each IGR is mobile or non-mobile or is capable or incapable of translocation in the environment.

Abstract: Methods and formulations for treating animal ectoparasites, effective against parasites such as fleas and ticks are provided. The methods comprise topically co-administering a non-mobile insect growth regulator, a mobile insect growth regulator, and an adulticide to the animal. Parasiticidal formulations for treating animal ectoparasites are also provided, which can be safe to use and avoids the many common deleterious side effects of conventional topical formulations. The topical formulations comprise a combination of two insect growth regulators and an additional insecticide. The topical formulation can be packaged together or packaged so that active components are stored separately prior to administering the topical insecticide formulation to the animal.
