The Department of Agriculture, Trade, and Consumer Protection (DATCP) conducts aerial sprays to slow the spread of gypsy moth in western Wisconsin. Traps are installed prior to the appearance of adult moths to determine where small, isolated populations may be present. These populations are then targeted using aerial sprays every spring and summer. To learn more about the program and find treatment updates, visit the DATCP webpage.
During the spring and summer months, aerial spray information is frequently updated on the toll-free gypsy moth information line: 1-800-642-MOTH. Press 1 to listen to a recording about the latest updates, including treatment locations, timing and completion. You can also subscribe to receive email updates about spray plans (scroll to "Plant Industry," click on "Spray Plans") or follow DATCP on Facebook or Twitter.
