About Seattle, WA's Carpet Beetles

Carpet beetles in Seattle, WA


  • Carpet beetles are varied in color, generally being black or brownish and often speckled.
  • Carpet beetles have complete life cycles, and may take up to three years to complete a life cycle.
  • Their eggs hatch in 17 to 18 days.
  • The adults live short lives from 14 to 40 days.
  • The larvae hatch and emerge in the Spring and will usually be found where the carpet meets the walls, and on the walls and ceilings.
  • They may infest odd areas such as wall or ceiling voids, attics, rodent baits, wasp and hornet nests, and animal trophies.


  • The larvae alone are responsible for damage to commodities.
  • Larvae feed on a wide variety of materials including; hair, fur, feathers, hides, horns, carcasses, dead insects, cereal, stored grain, nuts, seeds, cayenne peppers, and flour.
  • They love your clothes, will eat your drapes and make a mess out of your carpet. They hide in the wall and you won't find them until its too late!
  • Varied carpet beetles will feed on the food products in pantries.
  • The adults feed largely on pollen and nectar and are commonly carried into homes on flowers. A number of carpet beetles require pollen for successful production of eggs.


  • On furs they will cut the hairs at the base and leave the hide undamaged giving a bare appearance.
  • On fabrics they mostly graze on the surface but can also make irregular shaped holes. They may burrow through packaging when seeking food.


Often the Pest-A-Way Barrier is all that is really needed to control adult carpet beetles on the outside of a home. And by preventing them on the outside, the probability of an interior infestation is greatly reduced. In the case of an interior infestation an inspection/treatment will be necessary.
