Larva of a darkling beetle

7301.      We are experiencing a lot of sawdust on the floor of our log cabin. We keep sweeping it up, but it is there again in a couple of days. Obviously, something is eating the wood, so we sprayed the logs with Raid, and the insect/larva pictured was found on the floor a short while later. About six others also were found a couple at a time, in varying sizes, after repeated Raid sprayings. Some of the insects were much thinner and shorter. This was one of the bigger ones.However, Raid did not kill it. Could you tell me what kind of bug this is? We want to get an expert in to deal with this, but don’t know what insect is eating the wood. Thank you. Hagar, ON. Canada

 

Number 7301.  This appears to be a larva of a darkling beetle (Coleoptera: Tenebrionidae) in the genus Tenebrio, These may bore into rotten wood, but will not damage sound wood. They primarily feed on damp/moldy grains and the like. Darkling beetle detailed information
