Superior, WI (NNCNOW.com) --- Planes were flying over Superior Tuesday as the Wisconsin Department of Agriculture continues aerial spraying treatments to fight against the spread of gypsy moths.
Agriculture experts say gypsy moths, in their caterpillar stage, are among the most destructive and invasive species in forests across the U-S.
In an effort to reduce the population and slow the spread, pheromone flakes were dropped in an aerial spray across Douglas County today.
The pheromones are designed to disrupt the mating process of the insects.
"You have to picture that so many worms are eating trees that in July you could have an entire hill completely defoliated, looks like the middle of the winter."
The spraying wrapped up in Superior this afternoon but will continue in Washburn County before heading to Minnesota's Iron Range.
