Carpet Beetle Larvae: Persistent but Manageable Household Guests

A homeowner found carpet beetle larvae near stored dog food and, despite rigorous cleaning—vacuuming, sealing containers, relocating food—still spotted one larva daily. The expert reassured: dermestid beetles are ubiquitous in homes. Complete eradication is rarely possible, but numbers decline once the source (spilled pet food, woolens, dead insects) is removed.

If the infestation was recently cleaned up, residual larvae can persist for months before dwindling. Seeing an occasional larva doesn't mean a new infestation. Continue good sanitation; the population will stabilize at a low, unnoticeable level.
