I am not sure what bug this is, but hope is not a bedbug...
I found it on my bedroom and I have seen one on my kitchen. I am attaching a picture. Note that are not precisely flat, but a little round shaped.

Thanks very very much

Hi, Silvia:

Relax, they are definitely *not* bed bugs....

This is at least the third question I have had in the last month that included images of "spider beetles."  Yours represents one of three possible species, either this one:

or one of these two:

They are harmless, but may occasionally infest stored foods in the pantry, especially flour and other grain-based substances.  It would be a good idea to check the cupboards for any potential sources of the beetles and discard the infested goods.

Store all vulnerable foodstuffs, including dry pet food, in glass, metal, or plastic containers with tight-fitting lids.  Cardboard boxes and plastic bags offer no barrier to stored product pests.

Please consider sending me these images, as I'd like to do a blog post about them that I can refer people to.  Thank you (bugeric24ATyahooDOTcom).

I answer insect and spider identification questions ONLY. Attach images if possible. No "what bit me?", "what do I feed this bug in captivity?", or science fair project questions please. NO TECHNICAL QUESTIONS ABOUT INSECT PHYSIOLOGY.
