darkling beetle

6036  Hey there, I am from the Cowichan Valley in BC and have just tonight found around 10 of these beetles in my house. They are black, not particularly shiny, quite rounded body with 3 defined segments. They’re all about an inch long or so.  I usually wouldn’t think much of seeing a bug or two get in, being raised around wildlife and forests and all that, but I thought seeing this volume of the exact same size and type of bug in one night might be cause for concern. We first saw in the bathroom, then bedroom and spare room when checking corners and around some laundry. We found a couple dead ones too which were likely stomped by accident. We are pretty clean folk and our place is newly renovated. We only just moved in about 2 months ago. My hope, based on other photos on this site, is that this is just happenstance and they came in as babies on the load of wood I brought in the other day and aren’t pests. I haven’t been able to see an exact match so I’m hoping for help here! I hate creepy crawlers and the fact we keep finding these is going to make it hard to sleep! Thanks! Jane

This is a darkling beetle (Coleoptera: Tenebrionidae), it resembles Eleodes pimelioides; see https://tinyurl.com/y7hwfl9q for an image. The larvae of these beetles are known as false wireworms, and feed on the roots of grasses. The adults are harmless nuisance pests.  Ed Saugstad, retired entomologist; Sinks Grove, WV.
