The natural predators of flies are several small insects found in North America. These insects feed on the larvae of flies and prevent them from breeding, which in turn helps keep the population down. Most species of fly predators do not pose a threat to humans. Some companies sell fly predator products in combination with other types of pest control products. These products contain a variety of species, including Muscidifurax raptorellus, Muscidifurax zarapto, and Spalangia cameroni.
Hover flies are a family of flying insects that are beneficial to plants. They hover over flowers, feeding on their pollen and nectar. They are pollinators and predators, and their larvae feed on aphids and other insects. Although they may look like bees, these flies do not sting or bite humans.
Although many fly predator products are marketed for farm owners and equestrians, most people can benefit from their use. The products can help protect pets and children from disease-causing insects, and can reduce the number of flies in the area. Furthermore, they can make outdoor activities more pleasant, and reduce fly infestations all year round.
Flies are often predated by bigeyed bugs, which are predacious predators of flies. They feed on the larvae of insects and their eggs, and sometimes even the adults of these pests. Their prey include small, gray, silver-white, or black insects. They are commonly found in agricultural systems and are attracted to plants and flowers.
