Ag Department works to slow down Gypsy Moth spread in La Crosse County

La Crosse, WI (WXOW) -

LA CROSSE, Wis. (WXOW) – The Wisconsin Department of Agriculture flew over 13,000 acres in La Crosse County this week to spray fields to prevent a spread of Gypsy Moths.

The spray, which is “pheromone”, makes it difficult for male moths to mate with female moths. They spray these fields because the moth is quite destructive to trees and shrubs.

“The product that we use it's absolutely non-toxic to people, to pets, to animals, to birds, insects. It's not even toxic to the Gypsy moth,” Public Information Officer for the Department's Gypsy Moth program Rick Hummell said.

The Department will spray the insecticide along the Minnesota and Wisconsin border, and be used in Eau Claire and Dunn counties next week. “It (the moth) weakens the trees. It makes them susceptible to insects, to other diseases, and it would repeat defoliation and there's some evidence that yes, they'll kill the tree,” Hummell said.

Gypsy moths only lived for a few weeks at a time and look to reproduce quickly. The spray confuses the moth, and prevents the male moth from mating with a female moth in the short lifespan.
