Checkered beetle

6388  I found this in my bed in late May, just found another flying inside of my lamp last night. I have about 5 bites. The bites are mosquito like bumps that are extremely itchy even beyond 1 week. Very small. Black body with red stripe. Will have to zoom in picture to get best look. What is this? Should I get my house sprayed? Burlington, ON L7M 4A4 Canada

 

Number 6388. It’s a checkered beetle (Coleoptera; Cleridae). No need to be concerned about this one. Not only would it not be responsible for any bites but it is a beneficial predator on other small arthropods.
