Spotted Lanternflies: What Homeowners in Massachusetts and Connecticut Need to Know
If you've noticed large groups of colorful insects gathering on trees, fences, patios, or outdoor furniture, you may be looking at spotted lanternflies. While these invasive pests don't bite or sting, they can cause significant damage to trees, crops, and ornamental plants, making them a growing concern throughout Massachusetts and Connecticut.
What Are Spotted Lanternflies?
The spotted lanternfly (Lycorma delicatula) is an invasive planthopper native to Asia. Since arriving in the United States, it has spread rapidly across the Northeast, threatening vineyards, orchards, forests, and residential landscapes.
Adult spotted lanternflies are about one inch long with gray wings covered in black spots. When they open their wings, they reveal bright red and black hindwings that make them easy to recognize.
Why Are They a Problem?
Unlike many household pests, spotted lanternflies don't damage homes or bite people. Instead, they feed on the sap of more than 70 different plant species using piercing mouthparts.
Heavy infestations can:
Weaken trees and shrubs
Stress grapevines and fruit trees
Reduce plant growth
Leave behind large amounts of sticky honeydew
Encourage the growth of black sooty mold
Attract nuisance insects like wasps, bees, and ants
The sticky honeydew can coat decks, patios, vehicles, outdoor furniture, and playground equipment, creating a messy nuisance around your property.
How Do They Spread?
One reason spotted lanternflies have expanded so quickly is their ability to hitchhike.
Their egg masses can be laid on almost any smooth surface, including:
Firewood
Outdoor furniture
Vehicles
Campers and trailers
Landscaping equipment
Pallets
Stone and building materials
Because the egg masses blend in so well, they're often transported long distances without anyone realizing it.
What Do Egg Masses Look Like?
Spotted lanternfly egg masses are typically about one inch long and resemble a smear of gray or tan mud. As they age, the covering may wear away, revealing rows of seed-like eggs underneath.
Egg masses are commonly found on:
Tree trunks
Fence posts
Outdoor furniture
Sheds
Firewood
Rocks
Recreational vehicles
Checking these surfaces before moving them can help prevent the spread of this invasive insect.
How Can You Help?
If you find spotted lanternflies on your property:
Avoid transporting firewood or outdoor items from infested areas without inspecting them first.
Scrape egg masses into a container filled with rubbing alcohol or hand sanitizer to destroy the eggs.
Remove tree-of-heaven when appropriate, as it is one of the insect's preferred host plants.
Report sightings if requested by your state's agricultural or environmental agencies.
Even simple actions by homeowners can help slow the spread of this invasive pest.
Does Pest Control Help?
Professional pest control can help reduce spotted lanternfly populations around your home, particularly when adults or nymphs are gathering in large numbers on ornamental trees and landscaping. However, because these insects are widespread and highly mobile, no treatment can completely eliminate them from an area.
An integrated approach, including monitoring, reducing attractants, inspecting for egg masses, and targeted treatments when appropriate, is the most effective strategy for managing spotted lanternflies.
Protect Your Property
Spotted lanternflies are more than just an outdoor nuisance. Their feeding can weaken valuable trees and plants while creating sticky, unsightly messes around your home. The mess they leave behind is also known to attract nuisance insects like wasps and hornets.
