A number of the synthetic pyrethroid insecticides can work against larder beetles (and many other insects due to their broad spectrum of activity). Active ingredients in this group include: bifenthrin, cyfluthrin, cypermethrin, lambda-cyhalothrin, deltamethrin, permethrin, and others. Many of the product labels will list larder beetles or other beetles from the same family (Dermestidae, or the “carpet beetle” family).
