Introduction to Carpet Beetles
Carpet beetles are a common household and commercial pest in Central, VA. They are known for damaging clothing, furniture, carpets, curtains, and other fabric items. Four different species live in Central, VA, and each can harm your possessions, making it important to understand their behaviors, habitats, and the best ways to keep them out of your home.
The 4 Species of Carpet Beetles in Virginia
Common Carpet Beetles (Anthrenus scrophulariae)
Adult common carpet beetles are tiny, oval-shaped bugs that grow only about 2 to 4 millimeters long. They usually look black with colorful, patterned scales on their backs, but as they get older, those scales can fade or wear off, leaving them looking dull or discolored.
Varied Carpet Beetles (Anthrenus verbasci)
Adult varied carpet beetles are small bugs, about 3 to 5 millimeters long, with a black shell patterned in brown, white, and sometimes yellow. At first glance, they can look like tiny ladybugs, but their colors set them apart. Their young, called larvae, are brown, hairy, and more destructive than the adults.
Furniture Carpet Beetles (Anthrenus scrophulariae)
Adult furniture carpet beetles are very small, rounded insects that grow about 2 to 3.5 millimeters long. They’re mostly black but have yellow and white scales on their backs and legs, giving them a speckled look. Their colors can vary, and unlike other carpet beetles with long, narrow scales, these beetles have rounder, oval-shaped scales.
Black Carpet Beetles (Attagenus unicolor)
Adult black carpet beetles are small, dark brown to black insects that grow about 3 to 5 millimeters long. Their larvae look very different, with longer bodies covered in bristles at the tail end.
Carpet Beetle Habitat
Carpet Beetles live and thrive indoors and outdoors in Central, VA. Outside, they are found near pollinating flowers, abandoned bird and wasp nests, and abandoned spider webs. Inside your home, they enjoy dark, quiet areas where products made of natural fibers are present, such as closets, attics, and under furniture. Their larvae feed on carpets, rugs, clothing, upholstered furniture, curtains, and other products made of wool, cotton, and other animal-based fibers. If they get inside, they can easily spread and go unnoticed until damage appears.
Lifestyle and Behavior
Adult carpet beetles prefer to be outdoors, but they are attracted to light and often sneak inside buildings through doors, windows, or on flowers. Adults only feed on pollen and nectar, but their larvae are damaging to fiber materials. Carpet beetle larvae feed on a multitude of things including:
- Animal products like wool, silk, fur, leather, hair (including human hair), feathers, and pet dander.
- Food: Flour, grains, cereals, spices, seeds, and pet foods usually found in a pantry.
- Debris: Lint, dead insects, and debris in abandoned nests.
Carpet beetle larvae have also been found feeding on piano felts!
Are Carpet Beetles Dangerous?
Carpet beetles do not bite humans or pets, but they can cause serious problems around your home. Since they can go undetected for a long period of time, the larvae can seriously damage clothing, carpets, and furniture.
Carpet beetle larvae also shed hairs, which can irritate skin and be confused for insect bites. Even though they don’t spread disease, they are an unsightly and unwanted pest.
DIY Pest Control for Carpet Beetles
There are a few steps you can take to protect your home or business from an invasion of carpet beetles. First, you should thoroughly clean your home by vacuuming carpets, rugs, and upholstered furniture. This will remove larvae and eggs before they can spread.
Second, wash all clothing, curtains, and bedding in hot water to eliminate any hidden adults, larvae, or eggs. You should also store unused clothing in sealed containers and keep food in sealed packaging.
Finally, dust all surfaces, baseboards, and seal any cracks in windowsills and doorframes. If the infestation is stubborn and you can’t get rid of the beetles, consider calling a local pest control service.
