Spotted lanternflies have established populations in nearly 150 Massachusetts communities, prompting state officials to warn that eradicating the invasive insect from the region is unlikely. According to the Massachusetts Department of Agricultural Resources (MDAR), the pests now occupy every region of the state except the Cape and Islands.
Spotted Lanternflies Invade Nearly 150 Massachusetts Communities
First identified by their gray wings with black spots and red hindwings, spotted lanternflies do not bite, sting, or pose a direct threat to humans and pets. However, MDAR reports that the insects feed on the sap of more than 100 plant species, causing serious injury to vulnerable trees and crops.
Honeydew Residue and Sooty Mold Damage
As the insects feed, they excrete a sticky fluid called honeydew that coats trees, vehicles, decks, and outdoor surfaces. According to MDAR, this substance attracts bees, wasps, and ants while fostering the growth of a dark, unsightly fungus known as sooty mold.
Recognizing Grayish Mud-Like Egg Masses
In the late summer and fall, female lanternflies gather in large groups on trees and buildings to lay eggs. These egg masses measure about an inch long, feature a flat, grayish texture, and often resemble a simple smear of mud on outdoor surfaces.
Four-Step Citizen Containment Action Plan
State officials ask Massachusetts residents to actively participate in containment efforts by following four key management steps:
- Inspect vehicles: Check cars and trucks before leaving known infested zones and remove any hitchhiking insects.
- Vacuum pests: Search homes and businesses for live lanternflies and use a vacuum cleaner to remove them.
- Destroy egg masses: Scrape off and crush grayish egg masses found on outdoor surfaces.
- Report new sightings: Take photographs of suspected lanternflies in unconfirmed areas and submit reports via mass.gov/slf.
Management Guides for Heavy Infestation Zones
Property owners located within heavily infested zones can consult the official MDAR Spotted Lanternfly Management Guide for detailed pest control strategies and containment guidelines.
