Spotted Lanternfly Information

Spotted LanternflyThe spotted lanternfly is a serious invasive pest that feeds on sap from over 70 different plant species. It excretes honeydew while feeding, which results in mold covering the plant and anything nearby. While spotted lanternflies do not directly hurt humans or animals, they can negatively impact our agriculture, economy, and everyday life.  

According to the New Jersey Department of Agriculture (NJDOA), Monmouth County is in the "spotted lanternfly quarantine zone". Most spotted lanternflies reach adulthood by September and lay eggs through December.

The NJDOA is urging anyone who comes across the insect to destroy it immediately to help slow the spread. The Middletown Health Department also encourages residents to utilize the NJDOA's checklist for spotted lanternfly quarantine areas, in an effort to stop the spread. You can also learn how to make your own spotted lanternfly circle trap with Penn State Extension.
