Abstract A pest control composition in a solid stick form is provided for topical application around the neck or on the face of domesticated animals such as dogs, cats, cattle, horses and the like to control fleas, lice, ticks, flies, and like pests. Topical application about the neck or face of the animal in an amount ranging from about 0.1 to 0.3 grams, preferably about 0.13 to 0.25 grams, per kilogram of body weight results in the elimination of all fleas at the end of twenty to twenty four hours, a single application being effective for one to two weeks in most cases without evidence of irritation to the animal. The stick composition of the present invention comprises 0-(2isopropoxyphenyl)-N-methyl-carbamate as the active ingredient uniformly dispersed in a compatible solid base material and in a stable state. The present invention provides a pesticidal package for applying the composition to the neck or face of the animal.
A pest control composition in accordance with claim 1, wherein said composition additionally contains not more than 0.1 percent by weight of a bitter tasting compound.
