Hi! Every year starting in July or August I get these tiny flying insects inside my house. They come in through the window screens and then through the window frame of the closed windows. They are really tiny and sort of look like a flea but wings. They have clear wings and a black body. They are attracted to light. I have searched for hours but can not find out what these are. They do not bite. I took pictures of the ones that are on the fly window strips but did not see any place to attach them to this email. Any help you can give me to identify these is greatly appreciated. Thank you

From the images sent outside of this system, and with consultation from our state extension entomologist, I beleve these insects are dark-winged fungus gnats, Family Sciaridae. All fungus gnats feed on decaying organic matter. Outdoors this is mulch, composts from the compost pile, soils with a high organic matter content, etc. they are part of a natural cycle, while at times can be bothersome. Usually worse with constant moisture keep the organic matter wet. Fungus gnats with wings can travel short distances, so the source may not be your own yard. Consider contacting your local County Extension Service for a more localized focused response to this situation.
