What Does a Lanternfly Nest Look Like

The spotted lanternfly may be pretty, but this invasive insect threatens New York City trees and the Northeast. As a tree service committed to protecting the health of trees in the Bronx and Manhattan, we want to help you identify spotted lanternfly nests so you can take action.

Spotted lanternflies don’t build traditional nests, but they lay egg masses on tree trunks, branches, and other outdoor surfaces. Here’s what to look for:

  • Appearance: Egg masses resemble patches of light brown or gray mud smeared across a surface. Older egg masses might appear cracked.
  • Location: Check tree trunks and branches, rocks, outdoor furniture, grills, vehicles – any smooth surface. They have a preference for the invasive Tree of Heaven.

Identifying Spotted Lanternfly Egg Masses: More to Know

  • Time of Year: Egg masses are common in fall and winter but can be present at any time.
  • Honeydew and Sooty Mold: Lanternflies leave sticky “honeydew” that attracts black sooty mold. Look for dark patches beneath trees.
  • Swarms of Adults: In late summer and fall, you might see groups of these striking insects with spotted wings and bright red hindwings.

Why Spotted Lanternflies Are a Problem

Spotted lanternflies feed on tree sap of local trees. This damages and weakens trees, making them vulnerable to other diseases and pests. They threaten parks, landscapes, and even crops like grapes.

What to Do if You Find a Spotted Lanternfly Nest

  1. Don’t Panic! Take a photo and note the location, but infestations can be managed.
  2. Report It: Contact New York’s Department of Agriculture and Markets (https://agriculture.ny.gov/spottedlanternfly).
  3. Scrape and Destroy: If you can safely reach the egg mass, scrape it into a container filled with rubbing alcohol or hand sanitizer. Double bag and dispose. Wear gloves.
  4. Call the Professionals: Our experienced tree service team can assess the situation, identify other potential infestations, and provide treatment solutions.
