Public Meeting Scheduled on the 2018 Gypsy Moth Suppression Program in Dane County

5201 Fen Oak Drive – Conference Room 121

Madison, WI 53718


Dane County Parks, the Wisconsin Department of Natural Resources, the City of Madison, the City of Sun Prairie and the Dane County Tree Board will hold a public information forum about the 2018 Gypsy Moth Suppression Program in Dane County on February 12, 2018.  The meeting will be held at 6:00 pm at the Lyman Anderson Agriculture and Conservation Center, 5201 Fen Oak Drive, Madison WI 53718.  Representatives will provide information on the biology and life cycle of the gypsy moth and discuss gypsy moth management and control.  Questions from the public will be welcomed.


The gypsy moth can be a serious tree pest.  In large populations, gypsy moths can defoliate trees and kill those that are already under stress.  In addition, some people experience allergic reactions caused by contact with gypsy moth egg cases or caterpillars. The Gypsy Moth Suppression Program is intended to help reduce these effects.  In mid-May to early June, a small low-flying airplane will apply Foray®, a bacterial insecticide containing Bacillus thuringiensis kurstaki (Btk).  Btk is a naturally occurring strain of soil bacteria that is commonly used by organic gardeners to control pests. Btk has no apparent toxicity to people, animals, or insects other than caterpillars.


For 2018, there are 7 proposed treatment blocks in the City of Madison, covering approximately 500 acres.  There is 1 proposed treatment block in the City of Sun Prairie covering approximately 50 acres.
