Cover the dish with plastic wrap and secure it with a rubber band, then poke small holes in the plastic wrap. Gnats will be attracted to the scent of the vinegar, enter through the holes and get trapped in the dish. You can also try this with red wine in place of vinegar.

  • Dry out breeding sites: Gnats breed in damp environments, so keep your environment as dry as possible. Fix any leaks in pipes, faucets or any other areas where water might accumulate.

Sweat, breath, tears and body heat are the most significant attractants, according to Orkin, because gnats are drawn to the salts, minerals and other nutrients found in human sweat.

Also, avoid wearing strong fragrances or scented lotions and use insect repellents, particularly during peak gnat activity periods.

Are gnats harmful to humans?

Gnats are generally not harmful to humans. However, some species can bite and one of the most common types in Arizona is the biting midge, also known as no-see-ums.

Biting midges are tiny flies that can deliver painful bites. They are most active during dawn and dusk and are often found near bodies of water, such as ponds, lakes or marshy areas. Their bites can be irritating and cause itching, redness and minor swelling. Using insect repellent and wearing protective clothing can help.

Finally, regularly clean up decaying organic matter, such as fallen leaves or fruits, to minimize gnat breeding grounds, according to Orkin.

What months are gnats most active?

In Arizona, the peak gnat activity months are generally from April to October. During these months, the conditions are more favorable for breeding, leading to increased gnat activity.

How long does a gnat infestation last?

In Arizona, the duration of a gnat infestation can vary depending on the species of gnat, environmental conditions and the effectiveness of control measures.

Typically, gnat infestations in Arizona can last from a few days to a few weeks, according to the University of Arizona. However, with proper control and prevention, you can significantly reduce their numbers and eliminate the infestation within a matter of days to a few weeks.
