Awareness and Treatment for Lantern Flies Nest in the Fall
Fall is when spotted lanternflies lay their egg masses, making it a critical window for detection and treatment. Each mass can produce dozens of nymphs by spring, so destroying them now heads off next year's infestation, the same nymphs covered in the early warning signs to watch for.
Egg masses show up as grayish-brown, mud-like smears about an inch long and three-quarters of an inch wide. They can turn up on almost any flat surface: trees, rocks, fences, vehicles, outdoor furniture. That's why properties in Windsor often find them on more than just the trees themselves.
To destroy egg masses, scrape them into a container of rubbing alcohol or hand sanitizer. Just scraping them onto the ground isn't enough, since the eggs can still hatch, and if you're already seeing tree disease symptoms tied to lanternflies, it's worth pairing egg removal with a targeted spraying visit.
For trees with heavy infestations, professional fall treatment reduces adult populations before they lay eggs, and a round of tree trimming afterward clears out the branches they favor most. Contact us for a lanternfly management plan built around your property.
