How to get rid of a wasp nest
Small, accessible paper wasp nests can be handled at dusk with a jet-stream wasp spray from 15+ feet away. Anything inside a wall, above ladder height, or larger than a softball is a call for a pro — and yellowjackets are a different problem (see that guide).
Tools
- ✓Reaches 20+ feet so you stay back. Look for 'kills on contact, sprays up to 20 feet'.
- ✓Wasps can't see red light. For inspecting at dusk without alerting them.
Materials
- +Industry-standard jet stream. 27 ft range, dielectric (won't conduct if hits wiring).
- +Backup choice if Spectracide isn't available.
- +Full coverage. No exposed skin while spraying.
- +For knocking down the empty nest the next morning.
Steps
-
1
Identify the species and nest size
Paper wasps build small, open-celled umbrella nests under eaves — manageable. Bald-faced hornets build large football-shaped enclosed nests — call a pro. Yellowjackets are typically in the ground — see that guide.

2
Plan your escape route
Know exactly which direction you'll walk after spraying. Clear obstacles. Keep your back to your retreat. Never spray while standing on a ladder.
-
3
Wait until full dusk
Wasps return to the nest at dusk and become sluggish in cool, dark conditions. Treatment at 9pm on a warm summer night kills nearly the entire colony.

4
Spray a sustained jet stream into the nest entrance
Stand 15–20 feet back. Aim for the entrance opening. Spray a sustained stream for 8–10 seconds. Don't move closer — the spray reaches farther than the wasps will.

5
Walk calmly away
Do not run, do not swat at any wasps in the air. Walk to your planned retreat. Stay indoors until morning.

6
Knock down the empty nest the next morning
Most wasps will be dead by morning. Use a long stick or broom to knock down the nest. Discard in a sealed bag. Scrape residue off the surface — the pheromone scent can attract new colonies.
