According to an update from the City of Janesville, they are continuing their efforts to remove spongy moths from Lustig Park. Spongy moths are an invasive, nonnative insect that can cause significant damage to oak trees by feeding on leaves in their caterpillar stage. If uncontrolled, the caterpillars can significantly impact the health and longevity of trees. The Janesville parks division has now begun aerial applications of horticultural oil via helicopter to control hatched caterpillars in the upper canopy. The next treatment is scheduled for Monday, May 16 as early at 5 a.m. The park will remain closed for part of the day following the application. If you have any questions on the project, call the Janesville Parks Division at (608) 755-3025.
