How to get rid of yellow jackets
Yellow jackets nest underground or in wall voids and can have thousands of workers by late summer. Ground nest treatment is doable for an experienced DIYer with the right dust — apply at full dark, do not plug the entrance immediately. Nests inside walls are a pro job.
Tools
- ✓Puffs dust into the nest entrance from a distance. Far more effective than spray for ground nests.
- ✓Backup option if you don't have a duster.
- ✓For finding the nest entrance at night.
Materials
- +Pro-grade pyrethrin dust with silica gel carrier. Best single product for ground nests.
- +More accessible alternative if Drione isn't available locally.
- +If you don't have a duster, this can work as a backup — but dust is more effective inside underground tunnels.
- +Long sleeves, pants tucked into boots, gloves, hat, and a face covering. Multiple stings are likely if anything goes wrong.
Steps
-
1
Locate the entrance during daylight
Watch workers entering and exiting in late afternoon. Mark the exact entrance with a small stake or stone 2 feet away — you'll need to find it in the dark.
-
2
Wait until full dark
Yellow jackets stop flying at dusk and most return to the nest. Treat between 10pm and 4am. Use only a red-filtered flashlight.

3
Puff dust into the entrance
Stand back at arm's length. Puff 3–5 strong shots of dust directly into the entrance hole. Workers carry the dust deeper into the nest as they walk through it — this is why dust beats spray.
-
4
Do NOT plug the entrance immediately
Counterintuitive but critical — leave the entrance open. Workers leaving and returning carry dust to every corner. Plugging the hole traps the colony but doesn't kill them fast enough; some chew out a new exit.

5
Walk calmly away and stay back for 48 hours
Don't return to inspect. Stay 20+ feet from the entrance for 48 hours.

6
Check activity at 48 hours and re-treat if needed
If you still see foragers entering or exiting, apply a second dose at the next full-dark window. Most nests are 90%+ dead after one treatment.
