Spotted Lanternfly: America's Most Wanted Invasive Pest

The invasive pest threatening US crops, forests, and agriculture across 17 states

Arrived in 2014, Now in 17 States

First detected in Pennsylvania in 2014, it has spread to 17 states. The USDA estimates $554 million in annual agricultural losses.

$554M Annual Threat to US Crops

Lanternflies feed on grapes, apples, hops, peaches, and 70+ plant species. Honeydew excretions cause black sooty mold, devastating orchards.

How to Stop the Spread

Check vehicles before traveling. Scrape egg masses. Report sightings. States have quarantine zones. Biological control with Asian wasps is being tested.

Tree of Heaven: Its Deadly Host

Tree of Heaven (Ailanthus altissima) is the primary host. It grows in roadsides and forests across the East Coast.

Climate Change Is Making It Worse

Warmer winters allow more eggs to survive. Scientists project expansion into the Midwest and South as temperatures rise with climate change.

Report. Contain. Protect.

If you see a spotted lanternfly, report it to your state agriculture department immediately. Every sighting helps protect American farms and forests.
