Discovering tiny, dark beetles in your home can be unsettling—especially when you realize they might be black carpet beetles. These small pests are notorious for damaging fabrics, carpets, and stored items.
This guide will help you identify black carpet beetles, understand the damage they cause, and learn effective control methods to protect your belongings.
Identification: What Do Black Carpet Beetles Look Like?
Black carpet beetles (Attagenus unicolor) are small, oval-shaped insects. Here’s how to recognize them:
Size: About 1/8 to 3/16 inch long (3–5 mm).
Color: Shiny black or dark brown.
Shape: Oval and slightly elongated.
Larvae: Fuzzy, carrot-shaped, and brown or golden, often mistaken for small caterpillars.
Adult vs. Larvae: Adults are the most visible, but larvae cause most of the damage.
You may find adults near windows or light sources, while larvae hide in dark, undisturbed areas like closets, under furniture, or inside stored boxes.
Damage: What Harm Do Black Carpet Beetles Cause ?
Black carpet beetles are destructive pests, especially in their larval stage. They feed on a variety of natural fibers and materials:
Fabrics: Wool, silk, cotton, and synthetic blends (if soiled with food or sweat).
Carpets and Rugs: Natural fibers are at risk.
Stored Items: Furs, feathers, leather, and even stored food products.
Other Materials: Upholstered furniture, clothing, and bedding.
Signs of an infestation include:
- Holes or irregular damage in fabrics and carpets.
- Shed larval skins in undisturbed areas.
- Tiny, dark beetles or larvae spotted in your home.
