The NJ Department of Agriculture has designated Hunterdon County as a quarantine county for the Spotted Lanternfly. Please take a moment to review the following information to understand the impact of this invasive pest and what to do if you see it in our area.
The Gypsy Moth, commonly recognized in the larva stage as the caterpillar covered with spiky hair and rows of blue and red warts, is one of the most notorious pests of hardwood trees in the Eastern United States. Since 1980, the gypsy moth has defoliated close to a million forested acres each year.
Gypsy moth larvae prefer hardwoods, but may feed on several hundred different species of trees and shrubs. In the East, it prefers oaks, apple, sweetgum, speckled alder, basswood, gray and white birch, poplar, and willow, but may also target cottonwood, hemlock, southern white cedar, and native pines and spruces.
Homeowners can consider one or more tactics to help reduce gypsy moth infestation on their property:
- Remove objects around the outside of the home that provide shelter for gypsy moth larvae and pupae, such as flaps of bark, dead tree branches, dead trees, boxes, cans, or old tires.
- Destroy egg masses found on outbuildings, on fencing, and in woodpiles. Egg masses can also be destroyed by painting them with commercially available products, such as liquid detergents.
- Place burlap wraps around trees to serve as a shade trap for older larvae when they seek out protected resting places during the day. The larvae can be manually collected and destroyed.
- Use barrier bands, such as double-sided sticky tapes, or sticky material such as Tanglefoot, petroleum jelly, or grease, to prevent larvae from crawling up the trunks of susceptible trees.
