Forty of the 50 U.S. states have at least one of targeted pests under federal quarantine, according to www.hungrypests.com, which is run by the U.S. Department of Agriculture. All of the 50 states that are listed have suitable habitats for more than one of the pests.
European Gypsy moth
The European Gypsy Moth is such a huge threat because its caterpillars feed on over 300 species of trees/shrubs and have ravenous appetites. The caterpillars defoliate trees, this makes the trees vulnerable to other diseases and pests. Some signs might include visible egg masses, caterpillars and adult moths, along with defoliated trees. The moth has been found in states such as Connecticut, Delaware, the District of Columbia, Illinois, Indiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, New Hampshire, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia and Wisconsin. Kentucky is considered to be at high risk.
