Ectoparasite control compositions

摘要

Provided are ectoparasite control compositions, a method of controlling an ectoparasite and uses of a composition for controlling an ectoparasite. The ectoparasite control compositions comprise a solvent and 1-methyl-2-nitro-3-Ä(3-tetrahydrofuryl)methylÜguanidine, wherein said solvent contains mainly N-methyl-2-pyrrolidone. The methods of controlling an ectoparasite, comprise applying to a host animal, an ectoparasite control composition which comprises a solvent and 1-mediyl-2-nitro-3-Ä(3-tetrahydrofuryl)methylÜguanidine, wherein said solvent contains mainly N-methyl-2-pyrrolidone.
