How to Report a Sighting

The Department no longer request sighting reports for spotted lanternfly (SLF) since populations have been detected throughout the entire state. In the beginning it was very important for the public to provide sighting reports and we would like to thank you for the support. Staff has confirmed SLF in all three counties of Delaware.

Now (September-April) is the time to search for egg masses on trees, shrubs, and other ornamentals. If you find an egg mass, use a stiff card (similar to a credit card) or a putty knife to scrape the egg mass into a Ziploc bag or other container. To ensure the eggs are killed, add rubbing alcohol or an alcohol-based hand sanitizer. Seal the bag or container and discard it. Remember that some egg masses will be unreachable in the top branches of trees, but every egg mass you destroy does make a difference.

Registration and training is available online at no cost through the Delaware Department of Agriculture.
