If high numbers of bites are observed, hold off irrigation in the vicinity and allow moist spots to drain and dry. Reduce breeding sites: Common breeding sites in community environments include over-irrigated turf and landscapes (Figure 6), splash pads (Figure 7) and poorly drained areas in parks and grounds, as well as indoor potted plants. In urban areas, they can breed in any muddy or moist location, such as over-irrigated mulch or sod, tree holes, new construction sites, indoor plant pots, and even water from air-conditioners. They are also reported from plains as well as mountain areas. Both sexes cause great annoyance during outdoor activities, in almost any habitat near water sources such as near springs, ponds or lakes, river banks, beaches, and swamps. They are usually active during dawn or dusk, and often go unnoticed owing to their small size. No-see-ums are seen in largest numbers in the summer, but in places with warm winters, they can occur year-round. One species (Culicoides sonorensis) is known to transmit the bluetongue virus, a serious disease of sheep and cattle. are known to cause an allergic reaction known as ‘sweet itch’ in horses. Vectors: Some of the blood-feeding species vector pathogens including bacteria, viruses, protozoa and filarial worms. Sensitive persons may develop long-lasting painful and itchy lesions. The welts or blisters can break open and bleed on scratching, and the itching may continue. The females feed on blood from various host animals including humans and cause painful and irritating bites, that may be accompanied by allergic reactions.īites usually appear as small red welts (about 1/8 th inch in diameter ) or water-filled blisters, that itch intensely (Figure 3). Both males and females feed on pollen and nectar, but the males are not a biting concern to humans or other animals. On close observation or under a microscope, they may appear like miniature mosquitoes (Figure 2).īiting concerns: Adult females need blood meals for their eggs to develop. They have short, stocky bodies with a shiny thorax (back) (Figure 1). They belong to the insect order Diptera, which also includes mosquitoes, midges and other biting and non-biting flies.Īppearance: The adults are small, dark flies, 1/8th to 1/4th inch in length, barely visible to the naked eye. No-see-ums in Arizona mostly belong to the genus Culicoides, in the family Certopogonidae. They are also known as punkies or sand flies. These bites may be from small biting midges, often called “no-see-ums”. Occasionally people are aware of small insects flying around them, but do not actually see them biting. However, sometimes all that can be seen are the bites, leaving the affected persons wondering what bit them. Some of these are from insects that can be seen, for example, mosquitoes.
