If you’ve spent any time outdoors this spring in Eastern Iowa, you’ve probably seen them. Swarms of black flies –most people call them gnats – that surround their victims in a frenzied cloud.
Bug experts say there’s not much you can do to protect yourself against black flies. The pests come out during the day; while mosquitoes come out toward evening, so you can either lock your doors and stay inside or put up with the huge welts they’ve been known to leave.

Removing the gnats’ habitat can reduce their population, as well as the number of mosquitoes, which start to appear about the time the gnats die. Linn County Public Health monitors for mosquitoes, which carry risk of diseases such as West Nile virus. Residents can report bad infestations to the health department at (319) 892-6000. Workers are using larvicide to control mosquito larvae in standing water, but the same can’t be used against black flies, which live as larva in fast-moving water such as rivers.
