When Do Wasps Get Aggressive in Nebraska?
Wasps are most defensive in late summer and early fall, when nests are largest and food sources shrink. Yellow jackets and hornets guard their nests closely, so do not approach or spray one at close range.
Why late summer
Nests grow all season. By August and September they hold hundreds of workers, and the colony turns to sweet foods and protein from picnics and trash.
Safety tips
- Keep children and pets away from the nest area
- Do not swat at wasps near food
- Cover trash and drink cans outdoors
- Avoid strong perfumes outside in late summer
When to call
Call for nests near doors, play areas, decks and in wall voids, or if anyone in the household has a sting allergy.

Frequently Asked Questions
Can I spray a nest at night?
Small nests are sometimes sprayed at night, but stings can still happen. Large or hidden nests are best handled by a professional.
What if the nest is inside a wall?
Do not seal the opening. A technician can treat the nest through the opening.
