Gypsy Moth Suppression Program

The gypsy moth is a serious pest of forests,
shade and fruit trees, and ornamentals in
the northeastern United States.  They were
brought to the U.S. from Europe in the 1860s
to cross-breed with the silkworm to improve
silk production.  Some of the insects escaped
captivity and became established in the
surrounding forest.

Although the gypsy moth can cause sub-
stantial defoliation that may lead to tree
mortality, the greatest public concern often
results from the nuisance problems these
insects cause.  Not only can the caterpillars
completely strip trees and shrubs of their
leaves, they also become bothersome as they
crawl on structures, sidewalks and patios,
and the continuous rain of droppings under
infested trees can be very messy.
