A pest notice is useful when it tells you what changes for your visit. Start with the location, the dates, and the instructions from the agency responsible for the park or treatment.
Check the location before changing plans
Regional pest guidance does not establish that a particular park has an infestation or a closure. On this site, a documented park impact appears on that park’s page. Regional notices are labeled separately.
Treatment schedules can change
Maryland’s Department of Agriculture publishes spongy moth treatment schedules and maps. Its schedule distinguishes planned treatment from completed treatment and explains that weather can delay or cancel a scheduled application. Follow the agency’s latest update when planning around treatment work.

Follow current official instructions
MDA maintains identification, reporting, and movement guidance for spotted lanternfly. Read the current agency page and linked instructions rather than relying on an old county list or social media post.

Check the park before leaving
Read the park’s official notices for any area-specific restrictions. A treatment announcement alone does not establish that a park is closed. Look for an explicit access instruction and its effective date.
