Gypsy Moth


Gypsy Moth


The gypsy moth, Lymantria dispar, is one of North America's most devastating forest pests. The species originally evolved in Europe and Asia and has existed there for thousands of years. In either 1868 or 1869, the gypsy moth was accidentally introduced near Boston, MA. Since then it has spread throughout most of the contiguous United States.

The primary detection method for this invasive pest is through the use of pheromone traps which strongly attract the male moths, trapping them in a glue material. The detection of moths in traps would result in the placement of additional traps and/or egg mass survey around the find locations. To date, gypsy moths have not been detected within our county.
