What is this bug that is black or dark brown, has an elliptical shape, can fly, but rarely does, doesn’t have noticeable wings, is drawn to light, but sometimes sits in my sink, and is seen most during the late afternoon. they mostly walk but can fly. Mostly seen in late afternoon and evening on the windows or sink or ceiling. Attracted to light above sink when it’s on. And most importantly how can I get rid of it?
