Madison - Aeriel spraying to protect trees from defoliation by gypsy moth is expected to take place in Milwaukee and Wauwatosa this week, perhaps as early as Tuesday, May 26th. Milwaukee County has requested this spray treatment in several parks where gypsy moth populations are high.
Spraying is weather dependent and will begin after the Memorial Day holiday, when weather conditions are favorable. Program staff look for calm to light wind and no rain in the immediate forecast.
Typically, spraying begins at dawn, although it can occur any time of day as weather allows. Spray planes fly low and are noisy. The twin engine plane used in this spring's Suppression Program is louder than other planes used in previous years to protect Milwaukee and Wauwatosa parks and properties from gypsy moth damage. Residents should be aware and expect a potential early morning flight.
Residents in treatment areas may wish to stay indoors with the windows closed or avoid areas to be sprayed while spraying is taking place. The spray is not harmful to people or pets but can be sticky. It is easily washed off with soap and water.
DNR offers two ways for residents to stay notified of spray plans:
