Carpet beetle (likely Varied Carpet Beetle or Black Carpet Beetle)

Natural Habitat

Indoors, especially in undisturbed areas rich in organic matter like carpets, rugs, upholstered furniture, clothing, stored foods, and animal products (e.g., fur, wool, silk, feathers, dried pet food).

Diet & Feeding

Larvae feed on natural fibers (wool, silk, fur, felt), dried animal products, stored grains, and sometimes synthetic fibers if mixed with natural ones. Adults feed on pollen and nectar outdoors.

Behavior Patterns

Larvae are the damaging stage, often found in dark, undisturbed areas. They are slow-moving and prefer animal-based materials. They go through several instars before pupating. Adults are attracted to light and often found near windows; they do not eat fabric. The life cycle can take several months to a year depending on conditions.

Risks & Benefits

Risks: Significant pests of homes and museums, causing damage to textiles, clothing, carpets, and stored products. Can trigger allergic reactions in some individuals due to shed larval skins or excrement. Benefits: Outdoors, they act as scavengers, breaking down organic materials, and adults contribute to pollination.
