MOTHPROOFING STUDIES WITH FENVALERATE1

Abstract

Fenvalerate (cyano(3-phenoxyphenyl)methyl 4-chloro-α-(l-methylethyl)benzeneacetate) applied to woolen cloth as a pressurized solvent-based formulation protected the cloth against feeding damage by larvae of the black carpet beetle, Attagenus unicolor (Brahm), of the furniture carpet beetle, Anthrenus flavipes LeConte, and of the webbing clothes moth, Tineola bisselliella (Hummel), both initially and after the treatments had aged for 15 months. The fenvalerate treatments that had aged for 6 months were also effective against the adults of the above species of fabric insects.
