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!
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.
