(AP) - Soggy conditions have produced a bumper crop of gnats in the Iowa City area, leaving residents with little choice but to swat the insects until conditions dry out.
Cool spring temperatures kept gnat eggs dormant until later in the season. The eggs then hatched at once when temperatures warmed in late May.
Patrick O'Malley, a horticulture specialist with Iowa State University, says the presence of gnats has intensified over the last few weeks as a result.
City officials recommend residents take personal gnat control, including bug spray and even dryer sheets. They also say the gnat lifespan only lasts about a month, so residents should experience relief soon.
