I'm hoping someone could help me. We just purchased our 8 baby chicks about 2 weeks ago and after reading the forums, and this thread in particular, I decided to start raising mealworms as a treat for them. I ordered 2000 mixed size from Amazon and received them today. I dumped the burlap bag into my substrate and 2 different size beetles came out with the larvae. I believe the single, larger beetle is the mealworm beetle but I'm not sure what the smaller beetles are (there are lots of them). I suspect it is a foreign grain beetle but I want to make sure before I start killing them off. Here is a picture of the smaller beetle (bottom middle against the side of the bin) next to a mealworm.
My current plan is to leave the single mealworm beetle in with the larvae, pick out and kill all other "grain" beetles, and move pupae and beetles out to other drawers as I get them. It seems like too much work to create a whole additional drawer for a single good beetle. Any other suggestions?
Thank you for any advice!
