FYI. From the DNR:
Gypsy moth spraying by the Wisconsin Department of Natural Resources (DNR) and the Wisconsin Department of Agriculture (DATCP) is expected to start this week in some counties. The projected dates to spray in the identified West Bend zone are May 12 - 15, 2010. Because spraying depends on appropriate weather conditions, this plan is subject to change.
Planes fly low and loud when spraying and may be single-engine yellow planes or red-and-gray twin-engine planes with 2 tail wings at the back.
To view the specific sites that will be sprayed in each county, visit http://gypsymoth.wi.gov. At the right-hand side of the page, click on the blue or yellow county you would like information about on the Wisconsin map. On the page that comes up next, you can open detailed PDF documents that show maps of the spray areas.
All sites will be treated with the active ingredient Btk. Btk is the common abbreviation for a naturally-occurring soil bacteria that, when eaten by gypsy moth caterpillars, causes them die within a few days. Btk is generally not harmful to people, pets or other wild species. The formulation to be used this spring has been listed by the Organic Materials Review Institute as acceptable for use in organic food production. However, if you are concerned, you may wish to avoid areas to be sprayed on the day that spraying occurs or simply stay inside with the windows closed during and for 1/2 hour after the spray treatment has been completed.
You can stay updated by calling the Gypsy Moth Information Line at 1.800.642-6684 (1.800.642-MOTH) and choosing Option No. 1.
