The spotted lanternfly (Lycorma delicatula), and spongy moth (Lymantria dispar) formerly known as the gypsy moth, are two invasive insects that lay eggs on trees and other flat surfaces.
Winter is an ideal season to check your trees and backyard for egg masses that could be from these pests and to scrape them off. Removing found egg masses helps to suppress new populations of these invasive species that would otherwise hatch in the spring.
Review the information below to learn how to recognize the egg masses of spotted lanternflies and spongy moths and what to do if you find them.
WHAT TO DO
- Scrape found egg masses off using a putty knife or thick plastic card. Extend your reach using telescoping extension poles with attached scrappers (view photos of this technique).
- Dispose of eggs in a container with some dish detergent, hand sanitizer or rubbing alcohol.
- For spotted lanternfly, save the bag and report it to the contact above.
- For spongy moth, dispose of the bag in the garbage.
