Hi, the entrance to my apartment complex has this weird fly problem that no one seems to be able to solve. There's a bunch of little flies that like to hover in a circle about 5 feet in radius and they spend the entire day there just "hovering." The problem doesn't occur at night. So far we've tried to aim a huge industrial fan at the swarm but then they just hover a few feet to the left or right of where the fan is blowing. There is no way to use electrical devices near that area so that is out of the question.
Does anybody have any secret methods to getting rid of these pests? Thanks!
