Diet & Feeding

Keratin-rich animal fibers including wool, cashmere, mohair, fur, feathers, and felt. They will also eat accumulated human hair or pet dander.

Risks & Benefits

Risks: Significant pest of textiles; larvae can cause expensive and irreparable damage to clothing, rugs, and furniture. Benefits: In nature, they help break down animal matter, but inside homes, they offer no benefit.
