I just moved into a house and I've noticed that it has quite a few of what I think to be flour beetles. They're dark-ish brown and don't have ridges like bedbugs do, they're smooth, and they're pill shaped. I think I've seen one or two in the kitchen but I mostly see them outside and in my bedroom. I found two dead ones on the side of my bed and found one crawling around on my sheets today. I've had bedbugs before, am using the same mattress that had them which is covered with a bedbug proof sheet with a certified bed bug proof seal on it that the exterminators put on the mattress, and these bugs don't look anything like any bedbug I've ever seen. They also don't seem to bite me, so I'm pretty sure they aren't bedbugs. I don't know why they're in my room though, I've heard they're more common in the kitchen. Is it more likely these are a different kind of beetle? If they are flour beetles, why are they in my room?
