📋 Steps
1
Confirm wasps vs bees — different rules apply
Wasps (paper wasps, yellow jackets, hornets): smooth, shiny, slender body; aggressive nest defenders; no honey in nest. Bees (honey bees, bumble bees): fuzzy, stout; less aggressive generally; honey bees may make honey. Never exterminate honey bees — contact a local beekeeper for free removal. Treatment approach differs completely.
2
For paper wasp nests under eaves (small, accessible)
Apply commercial wasp freeze spray (Raid Wasp & Hornet) at night when all wasps are in the nest and temperatures are below 60°F. Spray directly into the nest opening from 15 feet. Apply for 5-6 seconds. Retreat immediately. Wait 24-48 hours before checking. If no activity, remove and bag the nest in morning.
3
For large paper nests or bald-faced hornet nests
These can contain thousands of aggressive defenders. Do not attempt DIY removal of large nests. Professional treatment with appropriate PPE is the safe approach. Attempting DIY removal of a large active hornet nest is among the most dangerous pest situations a homeowner can encounter.
4
For underground yellow jacket nests
Wait until full dark (30+ minutes after sunset). Apply Delta Dust with a hand bellows directly into the entrance hole — 3-4 firm puffs. Step back 15 feet immediately. Do NOT seal the entrance tonight. Return in 48 hours — if no activity, fill the hole. This approach achieves 90%+ kill rate without triggering defensive response.
5
For nests inside walls (heard buzzing inside)
Do not attempt DIY. Professional treatment required. Injecting pesticide into a wall void without knowing the exit allows surviving wasps to find alternative routes into living space — potentially through outlets, baseboards, and ceiling fixtures. A PCO treats from outside and manages the ventilation carefully.
💡 Tips
- Yellow jackets that feel cornered are the most dangerous stinging situation — never seal a nest entrance while wasps are alive inside; always leave an escape route until the population is dead
- If anyone in your household has a known bee or wasp sting allergy, have your EpiPen accessible before any wasp nest treatment and have a second person present
- Some wasp species are seasonal — wait until October when colonies die naturally if the nest location allows it; the nest will be abandoned and can be removed without any chemical treatment
- Don't be fooled by a 'quiet' nest in the morning or on cool days — wasps resting inside are alert and will defend the nest when disturbed
