Flies reproduce rapidly in warm weather, increasing their population. Although they have a short life cycle, flies have an extremely high reproductive capacity and feed on diverse food sources. They are also strong fliers, as anyone who has tried to catch them in full flight can attest! Reduction of breeding sites will dramatically reduce the population in a given location. Surface sprays should be applied to where flies are likely to rest during the night or periods of inactivity. They are also attracted to baits because of their scavenging nature.
