What did the 2025 quarantine repeal change for Winchester homeowners?
Virginia's spotted lanternfly quarantine is gone: VDACS repealed it as of March 27, 2025, so Winchester and Frederick County households face no state limits on transporting the insect, or anything carrying it, within Virginia. It began here on May 28, 2019, grew to a dozen counties and ten cities, and ended once VDACS found it had stopped slowing the insect.
The habits the quarantine encouraged are still worth keeping. Look over your car, camper, boat trailer and outdoor gear before a trip, especially from late summer through winter, when adults and egg masses are around. One egg mass riding on a trailer tongue or a pallet of patio pavers can start a new infestation in a county that had none.
Shipping is where rules can still bite. A Winchester-area business sending regulated articles to a state or country with import restrictions may still need VDACS paperwork, such as a permit, a compliance agreement or a phytosanitary certificate, so ask the agency before the load goes. Over the line in West Virginia, the West Virginia Department of Agriculture sets its own rules, so homeowners in places like Inwood or Bunker Hill should check with that agency.
Why is the spotted lanternfly such a concern in the Winchester area?
Winchester is where Virginia first detected the spotted lanternfly, in January 2018, so it has had years to spread through yards, fencerows and woodlots here. The surrounding orchard country raises the stakes. The insect feeds on more than 70 plants, including grapes, apples, stone fruit and hops, and is considered a threat to the region's orchards and vineyards.
Virginia Tech's Alson H. Smith Jr. Agricultural Research and Extension Center, on Laurel Grove Road, studies the lanternfly alongside the brown marmorated stink bug. How much fruit loss the insect causes in any given year is still being measured, so be wary of confident predictions in either direction.
In a home yard the damage is mostly nuisance. A backyard grape arbor or a young peach tree can take a beating, but the usual complaint is honeydew: a sugary drip that coats decks, cars and furniture and soon grows a black film of sooty mold.
Does tree-of-heaven make a lanternfly problem worse?
It often does. Tree-of-heaven (Ailanthus altissima) is generally described as the spotted lanternfly's preferred host, and yards with a stand of it often see heavier numbers. Removing or treating those trees can help a lot, but the insect feeds on dozens of other plants, so taking out tree-of-heaven alone rarely ends the problem.
Tree-of-heaven is an invasive tree that sends up root suckers when it is cut, so felling a big one without treating the stump can leave a thicket of sprouts the next summer. Some property owners keep one or two as trap trees and have them treated, then remove the rest. Talk with a certified arborist or Virginia Cooperative Extension before cutting anything large.
- Long compound leaves with many paired leaflets
- Smooth, pale gray bark on younger trunks
- A sharp, unpleasant smell when a leaf or twig is crushed
- Clusters of papery seeds hanging on some trees from late summer into winter
When should spotted lanternflies be treated in the Shenandoah Valley?
Timing follows the insect's calendar. Egg masses laid in fall sit on bark, stone and outdoor items through winter, nymphs hatch from about May, and winged adults show up from about July into late fall. Scraping fits the cold months, while sprays and host-tree treatments target the nymph and adult season.
Valley weather nudges these dates a week or two either way, and yards up toward Great North Mountain can run a little behind the valley floor. The Shenandoah Valley pest calendar lines lanternflies up with stink bugs, ticks and yellowjackets, which helps when one visit can cover more than one problem.
- Late fall to early spring: find and scrape egg masses on trunks, stone walls, firewood, trailers and patio furniture
- About May and June: small black nymphs with white spots climb trunks and tender growth
- Early to mid summer: older nymphs turn red, black and white and crowd vines and young trees
- About July until hard freezes: adults gather on host trees, drip honeydew and lay the next round of eggs
Can I handle spotted lanternflies on my own?
For light numbers, yes. Scraping egg masses, swatting nymphs and hanging enclosed circle traps on trunks are all reasonable homeowner steps that cost very little. It is time to call when several trees are covered, honeydew is ruining a deck or car, or the egg masses sit too high to reach safely from the ground.
Leave open sticky bands off your trees. They trap songbirds, small mammals and helpful insects, and Extension guidance generally favors enclosed circle traps instead. If you use a garden insecticide, read the label for fruit trees, grapes and blooming plants before spraying anything near the harvest or the bees.
If you find lanternflies somewhere they have not been seen before, the Virginia Cooperative Extension office for Frederick County, on North Kent Street in Winchester, or VDACS can tell you whether to report them.
