How to Get Rid of Bald-Faced Hornets

Pro recommended
The honest answer is: don't attempt to remove a bald-faced hornet nest yourself. This species builds large, enclosed, basketball-sized paper nests that can house up to 700 workers, mounts a genuinely coordinated defense when disturbed, and can spray venom toward the eyes — and nests are frequently high in trees or under eaves, adding ladder-fall risk on top of the sting risk. What you CAN safely do yourself is identify the nest, keep household members and pets away from it, and use prevention (blocking potential nesting recesses in early spring, since nests are annual and not reused) to discourage a repeat next year. For an existing nest, call a licensed pest control professional with the right equipment and protective gear.

The verdict on Bald-Faced Hornet DIY

Pro recommendedPro only

Pro-recommended — a large, aggressive aerial nest is genuinely too dangerous to DIY.

The bald-faced hornet is actually an aerial yellowjacket that builds a large, enclosed gray paper nest — Penn State Extension notes colonies can reach "100 to 400 workers," and Orkin reports nests "as large as a basketball" with up to 700 workers. It's aggressive when disturbed, stings repeatedly, and can spray venom toward the eyes. Nests are also frequently high in trees, on utility poles, or under eaves — exactly the combination (height + coordinated defense) that turns a DIY attempt into a fall-and-multiple-sting incident. The honest DIY-appropriate piece of this job is identification, distance, and prevention; nest removal belongs to a licensed pro.

The playbook

The 5 DIY methods — honestly graded

Every approach graded for this species, in IPM order — prevention first, chemistry late. Pick a method to see how it works, the steps, and what it actually takes.

Prevention / Exclusion

Situational

Reduces the chance of a NEW nest forming; does nothing for one that already exists.

Bald-faced hornet nests are annual — the whole colony dies off at the first hard frost except for new queens, who overwinter and start fresh nests elsewhere the following spring. Monitoring likely nesting spots in early spring can help you spot and address a new nest while it's still small.

Best for: Catching next year's nest early and routing it to a pro before it grows

  1. Monitor in early spring

    Check trees, eaves, sheds, and utility poles for a small, early-stage nest starting in April–May, before it grows large.

  2. Call a pro for any nest you find

    Even a small bald-faced hornet nest is best handled by a professional given this species' defensive behavior — don't attempt removal yourself.

Reality check

Why DIY falls short here

Not scare tactics — the specific, proportionate reasons a home attempt can stall for this species.

Height and ladder risk

Aerial nests are often high in trees, on utility poles, or under eaves — a ladder combined with a defensive swarm response is a serious fall-injury risk.

Coordinated colony defense

With up to 700 workers, the colony mounts a coordinated response to disturbance rather than a few individual stings, so a botched DIY attempt risks multiple stings at once.

Venom can be sprayed toward the eyes

Bald-faced hornets can spray venom, making face and eye protection essential — protection a homeowner attempt often skips.

Straight talk

How risky is it, really?

An honest read — most nuisance species are genuinely low risk, and we say so.

High risk

This is one of the cluster's genuinely elevated-risk species for the general population, not just for allergic individuals — large colonies mount a coordinated, repeated-sting defense when disturbed, and nests are frequently in hard-to-reach locations that add fall risk to any DIY attempt.

When to call a pro

This One's Not a DIY Job

Up to 700 aggressive workers in a nest that's often high off the ground is a genuine safety risk, not a weekend project. Anchor Pest Services removes bald-faced hornet nests safely across southern and central New Hampshire. Family-owned since 2017, NH license #782664.

Call a pro when…

  • Any active nest — this species is pro-recommended at baseline, not just for large or hard-to-reach nests
  • A nest near an entry, walkway, or play area (added urgency)
  • A nest high in a tree, on a utility pole, or under an eave (ladder risk)
  • Anyone in the household has a known stinging-insect allergy (added urgency)

General Pest Control

This is the cluster's clearest call-a-pro case. Given the colony size, aggression, and typical nest locations, Anchor's licensed technicians handle bald-faced hornet nests with the right equipment and protective gear — don't attempt this one yourself.

Keep them out

  • Monitor likely nesting spots (trees, eaves, sheds, poles) in early spring
  • Keep household members and pets away from any nest you spot
  • Call Anchor at the first sign of a nest rather than waiting for it to grow
New Hampshire context

Bald-faced hornets in New Hampshire

In New Hampshire, bald-faced hornet colonies build through spring and summer and peak in size by late summer, then die off — except for new queens — around the first hard frost, roughly October 19–29 in Manchester (NOAA). An empty gray paper nest spotted in bare winter trees is not a danger and won't be reused, but a nest found during the active season should be treated as a call-a-pro situation, not a DIY project.

Peak season

Late summer, when colonies reach maximum size

Before you treat

Make sure it's a Bald-Faced Hornet

Two quick detours worth taking — confirm the ID, then learn what drew it in so it doesn't come back.
