The effectiveness of solvent-based deltamethrin sprays at 0.025 and 0.05% concen tration, resulting in 0.029 and 0.052% oww, respectively, were evaluated against the larvae of the case making clothes moth Tinea translucens Meyrick and the furniture carpet beetle Anthrenus flavipes LeConte. Deltamethrin spray at 0.025% concentration provided a high degree of protection to wool fabric from the larval damage of insect pests even after 30 months of ageing in dark storage. A spray of 0.029% oww delta methrin also protected the fabric after five drycleanings from the Tinea translucens larvae.
