Identification

The four most commonly encountered Carpet Beetles are the Black Carpet Beetle, Varied Carpet Beetle, Common Carpet Beetle and Furniture Beetle. Of these, the Black Carpet Beetle causes the greatest damage to fabrics. They are about an eighth of an inch long, oval-shaped, and shiny black with brown legs. The other beetles are rounder, smaller, and come in various patterns of white, brown, yellow, and orange with a gray to yellow underside.

Carpet Beetle larvae are about a quarter of an inch long and wider at the end of the body than at the head. These “infant” bugs appear to be hairy and have light and dark-brown stripes across the body. The larvae also have three dense tufts of bristles at the rear-end that extend outward when disturbed.

Education

Carpet Beetles can mate and reproduce without feeding. Depending upon the species, a female can lay 30 to 100 eggs in lint, floor cracks, or other dark, protected areas as well as behind and under baseboards. It takes about one to three weeks for the eggs to hatch in larvae. At this stage of development, the larva will shed its skin five to 12 times during a nine to 36 month-period. Eventually, the larva will develop into pupa, which usually lasts six to 24 days. Adults may not emerge for another three weeks.

Carpet Beetles prefer to live and breed in dark, undisturbed areas, including:

  • Closets
  • Attics Along and under carpet edges
  • Underneath upholstered furniture
  • In boxes where woolens and furs are stored

They may also live in air ducts where they like to feed on lint, pet hair, and other bits of debris. Adults are usually found feeding on flowers, but are sometimes seen indoors around light fixtures and windows on the south side of house.

Larvae are most likely seen on walls, along baseboards, or on counters. They feed on various textile materials and items composed of animal fibers including wool, furs, silk, feathers, felt, and leather. Polyester, rayon, and other synthetic fabrics are rarely attacked unless heavily soiled with food stains or body oils. Occasionally, the larvae will also feed on seeds, pet food, or cereal products in the kitchen or pantry.

As the larvae tend to wander from room to room, the infestation can spread throughout the house. Carpet Beetles may be coming from an abandoned bird or yellow jacket/wasp nest, or from a dead mouse or squirrel in the wall. As such, serious infestations of Carpet Beetles can develop undetected in a home, causing significant damage to clothing, bedding, floor coverings, and other articles. It is very important to locate the source as best as possible so that a professional can handle the infestation effectively.

Customer Preparation

Inside:

  • Check all potential food sources inside the house
  • Dry clean or launder woolens and other susceptible fabrics before storing. This not only removes perspiration odors that are attractive to Carpet Beetles, but also kills any eggs or larvae that may be present
  • Pack articles with mothballs or flakes in tight-fitting containers. Do no use insecticides to treat clothing. However, mothproofing solutions may be applied to susceptible clothing by professional dry cleaners
  • Vacuum routinely to effectively remove Carpet Beetles as well as any hair or lint, which may support future infestations.
  • Pay particular attention to the edges of carpets, along baseboards, underneath furniture, and similar “quiet” areas where Carpet Beetles prefer to feed

Outside:

  • Pick up any items from the floor (e.g., clothing, toys, newspapers, shoes, etc.)
  • Do all dry cleaning, then store in plastic clothing bags to reduce future infestations
  • Remove all items from infested closets and drawers

Customer Expectations from Treatment

In response to treatment, Carpet Beetles will act abnormally prior to death. The insects will come out of hiding and run across hard flooring or crawl two to three feet up walls to die. After this initial flushing, the abnormal activity should steadily decrease, but may take three to four additional flush cycles before the beetles under the carpet are completely reached. Keep in mind, our products kill Carpet Beetles on contact and act as a repellant by leaving a long-term residue that outlasts the lifecycle of the bugs.
