Spotted Lanternflies: (SLF) is an invasive insect present in Chester County and surrounding areas. SLF threatens agriculture, tree health and it is a nuisance pest. Chester County is within the SLF quarantine zone. Check for and remove SLF egg masses from late fall to early spring. Remember that egg masses may be underneath your car or in your wheel well. During all other times of the year, check for nymphs and adults, and keep your windows rolled up when you park. Don’t store things or park under infested trees, and do not transport firewood. Inspect your vehicle for SLF before traveling.
What to do
The Spotted Lanternfly (SLF) nymphs will be hatching as early as late April.
