Darkling beetle
#5549 Hi there, I live in Toronto, Canada. I recently moved in to a friend’s apt while he’s away for 2 months. I have felt itchy since the first morning I spent here, I also found what I thought could be bite marks on my hamstring and quad, I suspected that it could be a bed bug issue so I started checking the mattress. I found two 2 bugs on his mattress/box spring; I am attaching a picture of each. I am confident that they are not bed bugs but I still need to find out what they are so I can take the most appropriate plan to get rid of the itchiness. Any help would be greatly appreciated, thanks for your time!
This is a darkling beetle (Coleoptera: Tenebrionidae). Depending on its size, it could be either a mealworm adult (Tenebrio sp. – see http://tinyurl.com/puwfch2) or a flour beetle (Tribolium sp. – see http://tinyurl.com/zy5bfxj). As these can infest dry stored food products, you should check your food storage areas for signs of infestation. They would not be responsible for any bites or itchiness.
