Stopping the influx of flies before they happen is the most recommended of all flying ant treatments
. Locating any ant hills outside and treating with spray or power insecticide will prevent flyers from mating and quite possibly make a dent in the population of the colony. It may take several treatments before it is effective, but it could be because thousands of ants are involved. If a flying ant infestation is of significant proportions, it may be necessary to call in a professional for flying ant treatments.
