Lanternflies in Arlington

Published on July 17, 2025

While early detections were sporadic, we now anticipate that spotted lanternflies are here to stay in Arlington. Their population will continue to grow, but over time natural predators may begin to recognize them as a food source, which may help reduce their numbers.

Those who are certain they’ve identified a spotted lanternfly are encouraged to help slow the spread by squashing them on sight, destroying egg masses, and checking for them on cars or moving boxes before traveling. Please use insecticides sparingly as they could harm beneficial insects nearby.

Anyone who is unsure about identification, they should visit the County’s website for more information and photos.
