Wasp Nest Under Deck: Safe Treatment for Ground-Level Infestation

A homeowner reports "a bazillion" wasps or hornets flying around a ground-level deck, entering/exiting a partial bag of mulch under a canoe. One sting has already occurred.

Assessment

The nest is likely under the canoe, possibly inside the mulch bag. The exact entrance may be difficult to locate.

Treatment Protocol

1. Timing: Treat after sunset when wasps are less active
2. Product: Use a "wasp & hornet" jet aerosol (20+ ft range)
3. Application: Spray the entire area where wasps enter/exit
4. Safety: Plan an escape route; wear protective clothing
5. Follow-up: Monitor for activity; retreat if needed
