What harm do gypsy moths do?
Gypsy moth caterpillars feed mostly on deciduous trees and shrubs. When an infestation progresses, serious defoliation may occur and repeated defoliation may kill the trees. Equally offensive are the thousands of caterpillars and their droppings in residential areas and around home sites. The Asian Gypsy moth feeds on a much broader range of host plants than the European Gypsy moth.
