1 of my tenants has either fruit flies or Drain flies. Recently, this flies just appeared. There in the kitchen, garbage, bathroom, in the bed rooms a little bit, and even in the refrigerator. I know we had a moisture problem in the crawl space due too the heat pump from the old HVAC. We're using windows units temp. So the unit been off for a few weeks which means there wasn't any water dripping down there lately. Do you think the flies are coming from the crawl space up through the ac vents ? Are the coming from the drainers ? Where can they be coming from ? And how do I fix this issue ASAP ? Thank you. !!

Get a pest control company to tell you what kind of fly they are and what their likely source is. My guess is phorid fly and they're coming from the drains.
