What are these gnat size pests

Asked July 29, 2019, 1:45 AM EDT

These bugs are located in our bonus room, we find several dead on the couch daily and seem to come out at night when we watch tv. They ate micro or gnat sized. What are these pesty things?

Judging by the wing venation, this is a minute scavenger fly. These can be very common flies, but usually outdoors. These breed in decaying organic matter generally. So I would have you check window screens, make sure sink drains are clean and working properly, look at the potting soil around house plants to make sure it is not too wet, etc.
