Carpet Beetle (Larva)

Natural Habitat

Indoor environments, specifically within carpets, upholstery, closets, and baseboards; also found in bird nests outdoors.

Diet & Feeding

Larvae consume natural fibers such as wool, silk, fur, feathers, and hair, as well as dead insects and dried food products. Adults feed on pollen and nectar.

Behavior Patterns

Larvae are avoidant of light (negatively phototactic) and prefer dark, undisturbed areas. They undergo a long larval period lasting several months to over a year before pupating into beetles.

Risks & Benefits

Risks: Significant household pest that causes damage to textiles, clothing, and rugs. Larval hairs can cause 'carpet beetle dermatitis' (allergic skin reactions). Benefits: In the wild, they act as scavengers by breaking down organic animal matter.
