The Massachusetts Department of Agricultural Resources has officially confirmed established populations of the invasive Spotted Lanternfly (Lycorma delicatula) across Middlesex County, including Natick.

While completely harmless to humans and pets, these invasive plant-hoppers feed on sap from over 70 plant species, including local maples, grapevines, and fruit trees. They excrete a sticky waste called “honeydew” that promotes destructive sooty mold growth. 

The state advises residents to take the following steps. 

Kill adults on contact (the squish technique): Spotted lanternflies jump forward, not backward. Approach them directly from the front and stomp/squish them head-on.

Alternatively, spray them directly with a mixture of concentrated liquid dish soap and water to immobilize and kill them.

Scrape & destroy egg masses: Locate gray, mud-like egg masses on trees or outdoor surfaces. 

Using a plastic card or putty knife, scrape the eggs directly into a sealed container filled with rubbing alcohol or hand sanitizer. Simply scraping them onto the ground will not stop them from hatching. 

Report sightings: Help state entomologists track the spread by logging a photo and location.
