I have these small black flies that congregate on my carport, or any other dead air spaces. They dart back and forth, to and fro. They don’t gather where the dog poop is, so they’re not looking for that like regular straight flying flies. These little beggers sometimes get in the house. I don’t think they follow me around, but they always seem to be in the same room where I am. Sometimes, in the evenings, I catch them at the windows and squirt them with a mixture of Dawn detergent and water. It never fails. If I wait to the darkness of evening, turn off all of the lights in the house, then go into the bathroom, leave the door open and the bathroom light on, they’ll come in there. When they try to hide they find the dark shaded spots, like around the vanity, in the trash can, or under the toilet. I try to flush them out and force them to fly into the shower where they are limited in flight and I can liberally spay.
