How to Identify Spotted Lanternflies on Your Property
See a gray “mud smear” on a tree trunk, fence post, or even your patio furniture? That can be a spotted lanternfly egg mass.
If you’ve been searching “spotted lanternfly what to do,” you’re not alone. As this invasive pest spreads, many homeowners are unsure what steps to take first or how serious the problem might be.
Notice sticky drips and black sooty mold later in the year? That can be lanternfly honeydew.
Either way, late winter into early spring is a great time to act calmly and early.
What’s Happening and Why It Matters
Spotted lanternfly is an invasive, sap-feeding insect that can build up in noticeable clusters. The honeydew they produce can attract nuisance insects and contribute to sooty mold.
In North Carolina, the pest overwinters as egg masses. Egg masses can most likely be observed from mid-October through spring, and each mass can contain about 30-50 eggs.
Egg masses can be laid on tree bark and on smooth, man-made objects, which is one reason they spread so easily. Understanding what to do about spotted lanternflies early can help slow the spread and protect nearby trees and plants.
Spotted Lanternfly: What to Do Next (Step-by-Step)
1) Confirm what you’re looking at
Egg masses are grayish-brown, about 1 to 1.5 inches long, and often look like dried mud.
2) Scout the “usual suspects” first
Spotted lanternfly feeds on many plants (over 100 species) and has a strong preference for tree-of-heaven (Ailanthus altissima).
If you know you have tree-of-heaven nearby, check it and nearby trees through the season.
Also check outdoor items that move or get stored outside (firewood, trailers, grills, lawn gear).
3) Scrape and destroy egg masses you can safely reach
Homeowners are encouraged to scrape and destroy egg masses.
A simple method:
- Hold a bag or container underneath.
- Scrape with a plastic card or putty knife.
- Seal and crush, or dispose in sealed trash.
If egg masses are high up, numerous, or over a roofline, skip the ladder and call a pro.
4) Reduce “hitchhiking”
If you travel through known infested areas, check vehicles and outdoor-stored equipment for insects or egg masses.
5) Be careful with tree-of-heaven removal
Tree-of-heaven is invasive and a major host for spotted lanternfly.
Simply cutting it down usually won’t kill it because it resprouts, so control can require a plan that prevents regrowth.
6) Report what you find
If you think you’ve found spotted lanternfly in North Carolina, take a clear photo and report it to the state experts.
When to Call a Pro
Call a qualified professional when:
- You’d like a property-wide plan to protect high-value trees and reduce nuisance issues.
- Egg masses are out of reach or you’re seeing a lot of them.
- You suspect tree-of-heaven and want it identified and handled safely.
