ST. PAUL, Minn. - The fight is on to keep biting gnats from bothering Minnesotans this summer.
The Metropolitan Mosquito Control District is treating sections of Twin Cities metro area rivers to reduce gnat numbers. The insects develop in flowing water.
Walz said that gnat bites can be worse than a mosquito's bite.
A MMCD staff member, John Walz, said that the treatment is very specific and only targets gnats.
"After we treat, we can go downstream and pick up a branch that are hanging in the water where the larvae are or anything that they're hanging on to, look at it and go, "OK, all these gnat larvae are dead and everything else is alive.' And well, that's how specific the material is."
The treatment targets four difference species and can cut the population by more than 80 percent.
