Gypsy moths are a serious problem in pockets of Rock County.
UW Extension Horticulture Educator Mike Maddox says the moths don't kill a tree, but he wants to have a discussion with property owners about whether it's cause for panic. He says a large area of Beloit, a pocket north of Janesville and the south side of Janesville are infested with the moths.
Maddox is starting a series of educational events at Rotary Botanical Gardens with a discussion about gypsy moths August 7.
