What's That Bug? does not endorse extermination

Slow moving, tick-like bug
December 23, 2009
Hi bug people!
I have continuously seen these bugs in my bathroom, usually on the floor. I have never seen them anywhere else in my apartment. At first I thought they were ticks, but they crush very easily, and are round but don’t appear to be filled with blood. They move very slowly and the one I took a picture of was also moving very cautiously, exploring everything with its antennae. Not sure if this is normal, but when I used a flash, the bug appeared reddish (3rd photo). Otherwise, it appears black. It is also very very small, maybe about 1/2 cm. I’d really like to ID this bug to make sure it’s not posing any kind of risk to me by being there! Thanks in advance!

Dear EG,
This is a Spider Beetle, Gibbium aequinoctiale, a common pest of stored foods.  The origin of the beetle is unknown as it now has a cosmopolitan distribution.  Though you are finding them in the bathroom, unless you also store food there, you should look for the infestation in the kitchen.

    I probably have spider beetles. They are the dice of a tick or smaller. Do not move for days at a time. Looks like a bit of dirt but smear when they are crushed. They are in my powder room and along the crevice where carpet meets the woodwork under my living room windows. I also see some in the master bath on the floor. I am in a townhouse on a slab send I have two cats.
