(No-See-Ums, Biting Midges)

Several different species of midges may be encountered both inside the home and outdoors. Midges are small flies that range in size from 1/16 to ½ inch long. They range in color from light tan to light green to nearly black, depending on the species. Midges are often confused with mosquitoes. Midges are either non-biting or biting insects. Indoor varieties are non-biting and are more of a nuisance insect. Biting midges, often called no-see-ums, can be a nuisance to campers, fishermen, gardeners, and others who spend their time outdoors. The bites are irritating and painful. Biting midges can also be vectors of disease in humans and animals. Biting midges do not establish themselves inside homes or apartments.

Midges develop in wet areas such as lakes, ponds, slow-moving streams, drainage ditches or even wet mud. Large numbers of midges normally emerge at sundown and gather in swarms. Since these insects are attracted to light, they are often found near homes and structures. Some species are small enough to go through window screens and infest indoor areas.

Look for habitats where these insects can develop; i.e., drain away areas of standing water if possible. Reduce overall lighting on the outside of the home or consider yellow lights instead of white. Eliminate situations where indoor lights are shining directly through windows, or cover your windows by closing blinds and curtains.
