Yes, Permethrin SFR 36.8% can be used for carpet beetle larvae. You will need to use 1 2/3 fl. oz. for each gallon of water to get a 0.5% ratio. When using this product for carpet beetles the label states to apply the spray evenly to rugs, carpets, along baseboards and edges of carpeting, under carpeting, rugs and furniture, in closets, on shelving, and wherever else these insects are seen or suspected. For the best control of immature stages, we recommend adding an IGR (Insect Growth Regulator) to your insecticide, such as NyGuard EZ1.
