Hi Betsy The "ant" is a rove beetle (Staphylinidae) - just an accidental intruder, and not a threat other than providing food for pests like *Anthrenus*. The crime scene is evidence of active *Anthrenus *infestation - these are typical remains with frass after a good feed. In the top of the picture, you can see some fine hairs which the *Anthrenus *larva has shed while making its escape. It may be wise to replace the blunder traps more regularly - no point in leaving food around to keep the *Anthrenus *population going. Best wishes Tony Irwin
