Introduced into the United States from Europe in 1869,the Gypsy Moth is an invasive non-native insect with larvae that feed on many North American trees and plants. Gypsy Moth caterpillars prefer oaks and aspen, but are known to feast on more than 300 species of tree and shrubs. The caterpillars have insatiable appetites and can defoliate trees causing them to be vulnerable to diseases and other pests which can eventually kill the tree. Since their introduction into the United States, the Gypsy Moth has spread throughout the eastern seaboard, south into Georgia and west into Wisconsin and Missouri. The Gypsy Moth Suppression Staff work to monitor and treat for this damaging invasive pest in order to protect our valuable trees throughout Bay County.
