Gypsy Moth

Outbreaks of gypsy moth are not frequent but are unpleasant to live with when they do occur. Learn more about why populations grow and collapse and how you can deal with their impact.

Gypsy moth (Lymantria dispar L) caterpillars feed on the leaves of oaks, aspen, crabapple and many other types of trees. Outbreaks of gypsy moth are not frequent but when they occur, it can be unpleasant to live, work or recreate in an affected area. Gypsy moth caterpillars can be so abundant that many trees will be completely defoliated by early July. Several areas in Michigan experienced gypsy moth outbreaks during 2019, and populations may be high in some areas again during summer 2020. The links below provide information about gypsy moth, how it affects your trees and options for dealing with this invasive pest.
