Anyone every get tiny moth- like creatures on your screen doors?

I live in suburban Dallas and about a week ago I found dozens of tiny mothy bugs on the inside and outside of my second level screen door and the same scenario in another room’s screen window. I think they died after a cold streak but they came back! I thought (gulp) that they might be fruit flies but I can find no source of them in other areas of the house, even flying around the rooms with the screens. What the heck are these guys?
