Description

Diet

Carpet beetles are well known for eating away at our carpets and rugs. Their diet consists of feathers, furs, insects, dead animals, processed human food, skins, cotton, silk, and wool.

Predators

A variety of predators like ants and spiders will feed on carpet beetle larvae. No predators will exclusively eat carpet beetles and the larvae will hide in dark places to avoid them.

Life Cycle

All carpet beetles will go through metamorphism during their lives. They will pass through the egg, larval, and pupal points to reach full maturity. This can take two months to many years. Female carpet beetles can lay over 100 eggs which can hatch after 7–35 days. Four generations of carpet beetles can develop every year. It can take 9 months to 2 years for a carpet beetle to become a full adult. However, adults only survive for a couple of weeks. On the plus side for the beetles, the adults are skillful fliers and can live for many weeks without food.

Signs you have an infestation

Signs that you have an infestation is spotting their pellets and skin. You should also expect to see the adult beetles and their larvae. Adult guernsey carpet beetles have patches of brown, white, and black. They move slowly and if you touch them they will roll over. Identify the source of the infestations by looking where there is more beetles, skins, and feces.

Outdoor Treatment

First of all get rid of all nests and hives in your backyard. Those are great places for beetles to nest which you do not want. Then, spray liquid insecticide around the perimeter of your house. Make sure so wear proper clothing at all times before you do this.

Indoor Treatment

Vacuum your whole entire house especially where you think the infestation is. Throw away any items that are already infested. Wash all your clothing and fabrics with soap and hot water. If you want, you can go the extra length by steam cleaning your furniture and carpentry.

Prevention

Close your screen less doors and windows at all times to prevent the beetles from entering your house. Inspect all plants and flowers before they enter your house. Store unused clothing in airtight containers and let your clothing get some sunlight everyday.
