Yes. According to the manufacturer Gentrol Point Source is effective for carpet beetles. The disc contains the Gentrol Insect Growth Regulator (IGR) hydroprene for 90-day control of roaches and other stored product pests, like carpet beetles. Activating Gentrol Point Source is as simple as squeezing the raised end of the plastic disc. This releases Gentrol IGR onto a filter paper. From there, it moves up to 75 square feet, damaging pests and preventing them from reproducing.
