Entomology (Study of Bugs)/What could this be?


I live in Northern Ontario.  Just recently our house has a hard shelled, reddish brown bug with a round body and then the small head, with tiny legs (unsure how many) and is maybe 3 mm,s round. It seems to bite at night however the bites can't be felt. The only way we know it bites is from the tiny spots of blood found on the sheets.  Until the other day these bugs were confined to the bedroom, but we have found it now in the bathroom.  Do you know what this could be?


I think there may be two different things going on. The small hard-shell beetles are probably carpet beetles, see http://www.livingwithbugs.com/carpet_beetle.html for pictures. The bites may be caused by bed bugs, see http://www.livingwithbugs.com/bed_bug.html for details. Let me know what you think after looking over this material. Post a follow up if this raises questions.

I can answer questions in any area of entomology (study of insects, spiders, mites, ticks, and other terrestrial arthropods). Contact me about home and garden insects, insects that bite and sting, and insects that damage homes such as carpenter ants and termites.
