Planes to spray for gypsy moths in western WI


LA CROSSE (WKOW) – Single-engine planes will be flying across western Wisconsin this week to spray for gypsy moths.

The planes will drop pheromone flakes, which are about the size of a grain of rice, that trick adult male moths from finding females.  The flakes do not kill the insects but disrupt mating.

The spraying does not affect organic certification and it is not toxic to people, animals and other plants.

The invasive moth feeds on the leaves of oaks, crabapple, maples, birch and other species of trees and shrubs.

The spraying will run from Thursday to Saturday in parts of La Crosse, Jackson, Clark, Eau Claire, Chippewa and Taylor counties if the weather cooperates.
