Carpet beetles in bed can be a distressing discovery, especially when you're expecting a restful night's sleep. These tiny insects can infest bedding, mattresses, and even clothing, leaving behind tiny holes and a trail of waste. But what causes carpet beetles to take up residence in our beds, and how can we prevent them from becoming unwanted guests?
The Life Cycle of Carpet Beetles
Carpet beetles are the larvae of various species of beetles, including the common carpet beetle (Anthrenus scrophulariae) and the varied carpet beetle (Anthrenus verbasci). These larvae can survive for up to 2 years, during which time they feed on keratin, a protein found in animal hair, skin, and feathers.
Identifying Carpet Beetles in Bed
Carpet beetles in bed can be difficult to detect, but there are some telltale signs to look out for. Check your bedding and mattress for:

- Lace-like patterns or small holes in fabric
- Small, oval-shaped eggs or larvae
- Brown or black fecal spots
- A musty or unpleasant odor
