Why Late-Summer Wasps and Hornets Turn Aggressive — and When D.C.-Area Homeowners Should Call a Pro

My Pest Pros urges families to have nests removed before Labor Day gatherings and fall yard work

FAIRFAX, VA, UNITED STATES, September 1, 2026 /EINPresswire.com/ -- If the wasps around your deck seem bolder this month than they did in June, you are not imagining it. Late August is the busiest stinging-insect season of the year across Northern Virginia, Maryland and Washington, D.C., and My Pest Pros is urging homeowners to have nests handled professionally before Labor Day gatherings and fall yard cleanup.

The reason is straightforward: colonies reach their largest size of the year in late summer, and the food they have relied on all season starts to run short. That sends far more insects toward patios, grills, trash cans and picnic tables. University of Kentucky Extension entomologists note that yellowjackets are among the most unpredictable stinging insects in the country and will usually sting when a nest is disturbed — which is exactly what happens when one gets bumped, mowed over or trimmed into.

"A nest that was a nuisance in June is a real hazard by the end of August," said Brett Lieberman, Founder of My Pest Pros. "The nest doubled or tripled in size while nobody was looking. That is why families who never had a problem all summer suddenly have one right when they want to be outside."
Homeowners who spot a nest can schedule same-day or next-day treatment by calling My Pest Pros at 703-665-4455 or visiting https://mypestpros.com/.

My Pest Pros recommends leaving removal to a licensed professional when:
-The nest is near a door, deck, patio, playset or walkway
-The nest is in the ground, where its true size cannot be seen from the surface
-The nest is inside a wall, soffit or attic, where sealing the opening can push activity indoors
-Anyone in the household has a sting allergy, or reaching the nest would require a ladder

Until the nest is treated, families can lower the odds of a sting by keeping drinks covered outdoors, closing trash and recycling lids tightly, clearing fallen fruit from the yard, and walking calmly away instead of swatting.

"Every year we treat nests people found the hard way, usually with a lawnmower or a hedge trimmer," Lieberman said. "It takes us a few minutes. Waiting is
what makes it dangerous."
