The spotted lanternfly (SLF) has the potential to greatly impact agricultural crops and hardwood trees. This insect feeds on the plant sap of many different plants including grapevines, maples, black walnut, and other important plants in New Jersey. Learn more about the SLF, find homeowner and business resources, and find permit training information.

Emerald Ash Borer was discovered in New Jersey in May 2014 in Somerset County, and as of October 2015 has also been found in Bergen, Burlington, Essex, Hunterdon, Mercer, Middlesex, and Monmouth counties. Infestations throughout the U.S. and Canada have killed tens of millions of ash trees since 2002. Report signs of the beetle to the Department of Agriculture at 609-406-6939.

In the U.S., spotted lanternfly is an invasive species that could be very devastating to some New Jersey crops and hardwood trees. New Jersey populations were first detected in 2018 and are currently primarily distributed along the state's border with Pennsylvania. In response, the NJ Department of Agriculture has issued an eight-county quarantine. People and businesses traveling in and out of these counties (Burlington, Camden, Gloucester, Hunterdon, Mercer, Salem, Somerset, and Warren) should inspect their vehicles for hitchhiking SLF as well as inspect outdoor items such as firewood, paving stones, lawn equipment, etc. for egg masses; see Checklist for Residents Living in Spotted Lantenfly Quarantine Areas [PDF, 222 KB]. Quarantine compliance will reduce the spread of SLF to new areas and counties thereby protecting New Jersey resources including forests and agriculture.
