Abstract

Mixtures of (a) bis-(2-X-phenyl)carbodiimides in which X is an alkyl or cycloalkyl group, which carbodiimide may be further substituted on each phenyl group by one or more halo, alkyl or cycloalkyl groups, and (b) quaternary ammonium compounds demonstrate superior ectoparasiticidal properties. Ectoparasiticidal compositions comprising these carbodiimides and quaternaries are described.
