Subject: They're Here. Here's Your First Briefing.
🌡️ Your Area This Week
The mid-Atlantic is past 810 growing degree days — the threshold that triggers adult SLF emergence. Adults are out, feeding, and building toward peak numbers. Your highest-impact window is right now.
🔪 This Week's Mission
Hang a circle trap on your highest-pressure tree — today. If you have a Tree of Heaven on or adjacent to your property, that is your primary trap location. Wrap the circle trap snugly at chest height. Check it every 3–5 days. Empty into soapy water.
📍 Notable Sightings
- → First adults confirmed in Warren County, VA — western frontier expanding
- → Heavy aggregations in Howard County, MD — second year of significant presence
- → Loudoun County, VA reporting earlier-than-average adult emergence
