Spotted Lanternfly Population Decline in New Jersey: What Experts Say

The invasive Asian spotted lanternfly has plagued New Jersey since 2018. Over time, these pests have spread across the state, harming crops and plants. They have declined in several New Jersey areas, according to reports.

Experts attribute this population drop to many factors. Lanternfly populations may have suffered from this year’s harsh winter. The insect’s multiplication has depleted its main food sources, like the tree of heaven, which they need to survive and reproduce.

Officials warn that the spotted lanternfly remains dangerous despite this decline. The insect threatens grapes, apples, and hops. Plants are badly harmed by its feeding habits, which promote sooty mold growth.

The New Jersey Department of Agriculture is fighting the spotted lanternfly. Quarantine, sighting reporting, and public education are attempts.

The current population decline is positive, but scientists caution that spotted lanternfly comeback in New Jersey requires ongoing monitoring and prevention.
