The Current Gypsy Moth Advance
The current gypsy moth line of advance is in western Wisconsin, and as far south as North Carolina. The main gypsy moth line of progression is very near Iowa. It is considered to be about 25 miles east of the Mississippi River. To see what Iowa has been doing to manage the gypsy moth, please view our Gypsy Moth Management page.
Northeast Iowa and southeast Minnesota are now considered to be in the transition zone before the advancing front. If you reside in Iowa and you suspect gypsy moth as a new introduction to your area, please let us know by going to our Contact us page. We would be interested in taking a closer look.
