A bit strange, but here it goes;
Two winters in a row now I have had these flies showing up in the house only in the wintertime, they are about the size of a regular housefly, but have spotted wings. I have seen them at other homes as well, does anyone know anything about this type of fly, I searched the web and cannot seem to find it.
One or two show up everyday, just drives me nuts because I keep a clean house, where are they coming from?

there is a name (can't remember) for them and they are pretty common. you notice them in the winter b/c they are a little more adept than regular houseflies at staying alive in cold places. i've seen them alive in some funny places in the dead of winter where you would think they should be frozen solid. usually, stuck in some little nook in cranny in the freezing cold. they aren't able to move but shiver like crazy in what i can only assume is some type of survival mechanism.

Lund, they are otitid flies and belong to the family Otitidae. They don't hurt anything and you only see them in winter as they overwinter as adults. They come out in ones and twos because the places they are hiding warm up occasionally and they become active again. They will leave the house in the spring. They best way to keep them out is to treat with a residual insecticide in the fall before they try to enter the house. Depending on the type of siding you have will dictate what to use. Check with the entomology dept at NDSU for recommendations. Hope that helps.

It's really not that difficult. It depends on the siding type as i said. My aunt and uncle have them all winter too. It would take a bit of time, but a good crack and crevice treatment with a residual pyrethroid insecticide around the foundation, along the seams in the siding, the eaves, and around the door should knock them down pretty good. It would help to keep the ladybugs out as well. The time to spray would be about the time the house flies start hanging around on the south and west sides of the houses every fall. Best advice without seeing each individual case would be to call the Ento dept and expain the problem. They can recommend some applicable pesticides and application times and methods. They are a nuisance, but don't do any damage to the home. Hope it works out.

Back in my college days while building homes, I was told these were not a native species but introduced from Mexico and were transplanted here via insulation from there. Thus the term "attic fly"
Not sure if this is true or not, just what I was told. The old builders I worked with said they had never seen these here in ND until about 12-15 years ago.

Very interesting, Thanks for the inputs. I will be using the perimeter spray next fall for sure. I am not Bug Phobic at all, they are just sort of a creepy thing, middle of winter and all.

I talked to one guy that pulled a few strips of siding off his house in the winter to cut a hole to gain access to some plumbing. He said when he cut the styrofoam insulation out from under the siding, there were millions of "attic flies" everywhere. He immediately called an exterminator, thinking that they were eating the insulation or that he had a major infestation. He was told that it was actually quite common for them to get under the siding like that and it was nothing to worry about. Kind of a pain in the arse though.
