Drugstore beetle

7325.       These “beetles” fly and are approx 3-4mm in length. They are coming in through our very tightly sealed windows!!! It’s been -40C here recently. We have never had bugs in our house before and find this quite alarming! We are not finding them in food but mostly they stay close to the window area or sometimes on the wall close to a light. What do I need to do to kill these!! Thnx for your help!! PS We are located in southern SK- Saskatoon, SK. Canada

Number 7325.       This appears to be a drugstore beetle, Stegobium paniceum (Coleoptera: Anobiidae). This is a cosmopolitan pest species that can infest a very wide variety of dry stored food products. See Drugstore beetle detailed information .
