The AdultAdults are tiny (about 1/8 inch), round, and look like "mottled" ladybugs. They have a pattern of black, white, and orange scales on their backs.
The LarvaeThis is the destructive stage. The larvae are "fuzzy" or bristly little worms, often golden-brown or dark brown.
The EggsThey lay tiny, white eggs in dark, undisturbed places like the back of a closet or under heavy furniture.
The DietCarpet beetle larvae eat organic fibers. This includes wool, silk, fur, feathers, leather, and even dried pet food or dead insects inside your walls.
Hiding in the ShadowsThey prefer dark, undisturbed areas. You might not see the beetles, but you will find "shed skins" (molts) left behind by the larvae as they grow.
Seasonal ShiftsAdult beetles often fly inside in the spring (attracted to flowers), but the larvae stay inside year-round, slowly eating away at rugs and clothing.
Why do I have an itchy rash? I don't see any bugs.Some people are allergic to the tiny hairs on the carpet beetle larvae. This causes "Carpet Beetle Dermatitis"—a red, bumpy rash that is very frequently mistaken for bed bug bites.
Are they eating my cotton shirts?Generally, no. They prefer animal-based fibers (wool/silk). However, if your cotton shirt has food stains or sweat on it, the larvae may chew through it to get to the organic residue.
How do I stop them?Frequent vacuuming—especially in corners and under furniture—is the best defense, along with storing seasonal wool clothing in airtight bins.
