Yellowjackets & Bald-Faced Hornets: Late-Summer Nest Surges & Safety
By late summer in the Glens Falls and Adirondack region, stinging insect calls pick up fast. I hear the same story every August and September: “We were just mowing the lawn and the ground erupted with yellowjackets!” or “There’s a giant gray football-shaped nest in my tree—what do I do?”
If you’ve lived here long, you know how aggressive yellowjackets and bald-faced hornets can get once their colonies peak. Here’s what I look for, how I stay safe, and why calling a professional for hornet and wasp control is always the best move.
Why Stings Spike in Late Summer
- Colony growth: Yellowjacket and hornet nests start small in the spring but can reach thousands of workers by August and September.
- Aggression: As colonies mature, food demands increase and the insects become more protective of their nests.
- Nest locations:
- Yellowjackets often build in the ground, old rodent burrows, or wall voids.
- Bald-faced hornets build large aerial paper nests in trees, shrubs, and under eaves.
Once disturbed, these insects defend aggressively, stinging repeatedly.
What I Watch for in Upstate NY Homes
- Ground nests in lawns, near fences, or under decks.
- Aerial nests on maple trees, pine branches, or building soffits.
- Increased traffic of insects flying in and out of a single hole.
- Buzzing near playsets or grills, especially in August cookout season.
I encourage homeowners to scan their property regularly starting in June. Catching a nest early keeps it from reaching dangerous size.
Why DIY Isn’t a Safe Option
I know the temptation to grab a can of spray at the hardware store, but here’s why I don’t recommend it:
- Aerosols only reach the insects you can see—leaving the colony alive and angry.
- Spraying during the day, when the colony is active, can provoke a swarm.
- Sealing a nest entrance without eliminating the colony can drive yellowjackets indoors or deeper into the structure.
- Multiple stings pose serious allergy risks.
For significant nests, professional treatment is simply the safer choice.
My Approach to Stinging Insect Calls
When I handle yellowjacket or hornet removal in Glens Falls:
- Confirm species and nest type (ground vs. aerial).
- Schedule for cooler evening or early morning hours when activity is lowest.
- Use targeted, label-compliant treatments that eliminate the colony quickly.
- Remove or secure the nest site when possible.
- Discuss prevention—sealing wall voids, screening soffit gaps, and limiting food attractants like uncovered garbage or fallen fruit.
Prevention Tips for Homeowners
- Seal gaps in siding and soffits before spring to reduce nest sites.
- Cover trash bins tightly; yellowjackets forage for protein and sweets.
- Keep outdoor food covered during barbecues and picnics.
- Inspect decks, sheds, and play equipment for small starter nests in early summer.
