Practical identification guidance

How to confirm Carpet Beetles

Adult carpet beetles are small, rounded beetles; their banded, hairy larvae are the stage that damages natural-fiber materials.

Check these details

  • Look for adults at windows and larvae in dark textile storage areas.
  • Check for irregular surface grazing, shed skins, and lint or hair accumulations.

Avoid a false match

Lady beetles resemble some adults, while clothes moth larvae may cause similar fabric damage.

Best next step

Identify the larval food source before vacuuming and treating affected materials.
