Evaluation of efficacy of selamectin, fipronil, and imidacloprid against Ctenocephalides felis in dogs

Abstract

Selamectin is as effective as fipronil and imidacloprid in reducing C felis infestation in dogs housed for 3 months in a flea-infested environment under conditions known to support the flea life cycle, and in protecting against subsequent weekly challenges with C felis for an additional 2 months.
