Bathroom Fly

I’ve got a bug for you!!
These first started appearing in our bathroom early last spring. (2005) It seems like there is always one or two in our bathroom every morning. This is before the showers start and there hasn’t been any activity in the bathroom overnight. They don’t fly fast and easy to squash. They’re about the size of a pencil eraser. It’s annoying as hell! Mater bathroom (where they’re appearing) is on the 2nd floor of a 2 story house in Omaha, Nebraska. Any help as to what they are and where they’re breading? Don’t be confused by the picture. It might look like a common housefly, but it’s not. It’s smaller and doesn’t fly as fast.
Thanks in advance.

Hi Tim,
This is a Bathroom Fly, Clogmia albipunctata. Indoors, they breed in sink traps, drains and dead flow areas in household plumbing.
