Yes, the label states that you should spray once a month for best results. It is also very important that the source of the infestation (where the damaging larva is harboring) is discovered and eliminated, not just the visible adult insects you see wandering around. Until you find out what that is and deal with it you will continue to get more of the carpetbeetles emerging from hiding. Carpet beetles may be as likely to feed on grain based food materials as they are on animal byproducts. Pet foods stored in forgotten places, baking goods left too long in the cupboard, rodent baits tossed in the attic - all of these are quite susceptible to carpet beetle feeding. Plus, you also have the typical carpetbeetle diets of dead insects (wasp nests in the attic, dead insects in window sills), feathers (bird nests, dead birds), hair (dead rodents, wool products, trophy mounts), and other things made from animal byproducts. Once the source of the infestation is removed or cleaned, use Suspend SC and Gentrol IGR once a month until all of the beetles are gone.
