How to Get Rid of Cicada Killer Wasps

DIY-friendly
Despite their intimidating 1.5–2 inch size, cicada killer wasps are solitary ground-nesters that don't defend their burrows the way social wasps do, and the large ones dive-bombing people are males, which have no stinger at all — females sting only if handled or stepped on. In most cases the honest, correct answer is to simply tolerate a burrow or two, since they're beneficial predators of cicadas. If you want fewer of them nesting in your lawn, maintain thick, well-watered turf and mulch bare, sandy patches — cicada killers strongly prefer bare, dry, loose soil in full sun and avoid wet or dense-turf areas. Chemical treatment is rarely necessary and reserved for large aggregations right next to a walkway or patio.

At a glance

  • Difficulty: Beginner
  • Time: An afternoon of lawn care, or none at all if you choose to tolerate them
  • Cost: Low — grass seed, mulch, or nothing
  • Success: High — tolerance or simple turf/soil changes resolve most situations

The verdict on Cicada Killer Wasp DIY

DIY-friendlyBeginner

DIY-friendly — and often the honest answer is you don't need to do anything at all.

The eastern cicada killer is one of North America's largest wasps at 1.5–2 inches, and that size scares people into thinking it's dangerous — it's the opposite. This is a SOLITARY, ground-burrowing wasp that doesn't defend its burrow the way social wasps do. The large males that patrol and dive-bomb people have no stinger at all; entomologist Justin Schmidt calls the species "gentle giants of the wasp world." Females have a stinger used to paralyze cicadas but sting only if mishandled or stepped on. For most homeowners, tolerating a burrow or two, or making the lawn less attractive to nesting, is all that's needed.

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

Works well

The most reliable fix if you want fewer of them nesting — cicada killers strongly prefer bare, dry, sandy soil in full sun.

Cicada killers select bare, loose, well-drained soil for their burrows. Thickening turf, watering regularly, and mulching bare patches removes the soil conditions they're looking for, encouraging them to nest elsewhere.

Best for: Reducing nesting in a lawn or garden bed over a season

  1. Thicken and water your turf

    Overseed bare or thin patches and water regularly through summer — cicada killers avoid consistently moist, dense-turf areas.

  2. Mulch bare, sandy patches

    Cover bare soil near walkways, patios, or garden beds with mulch to remove attractive nesting substrate.

  3. Fix drainage issues

    Correct low spots or drainage problems that leave soil dry and loose in a way that draws nesting females.

Reality check

Why DIY falls short here

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

Fear-driven overreaction

People treat this "gentle giant" as a serious threat because of its size, spending effort and chemicals on a species that's genuinely low-risk and beneficial.

Recurring bare, sandy soil

Without turf and drainage fixes, the same bare patches re-attract new females year after year, undoing any one-time treatment.

Misidentification as the "murder hornet"

Cicada killers are sometimes confused with the Asian giant hornet, which causes needless alarm — the Asian giant hornet is not established in New Hampshire or the eastern U.S. at all.

Straight talk

How risky is it, really?

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

Low risk

This species' size dramatically overstates its actual danger. Males cannot sting under any circumstances, and females — despite carrying a stinger built to paralyze cicadas — sting people only if handled or stepped on. Entomologist Justin Schmidt describes them as "gentle giants of the wasp world," and per National Geographic, a female's rare sting reportedly hurts less than a sweat bee's.

When to call a pro

Even Low-Risk Pests Deserve an Honest Answer

Cicada killer wasps look alarming but are among the safest stinging insects to have in your yard. If you'd still like an assessment, Anchor Pest Services serves southern and central New Hampshire. Family-owned since 2017, NH license #782664.

Call a pro when…

  • A large aggregation of burrows directly beside a walkway, patio, or play area you can't route around
  • You'd prefer a professional turf/soil assessment to discourage nesting long-term
  • Anyone in the household has a known stinging-insect allergy and wants extra caution (though baseline risk here is genuinely low)

General Pest Control

Most homeowners never need a pro for cicada killers — tolerance or simple turf changes resolve the situation. Anchor is available if a large aggregation sits somewhere you truly can't avoid.

Keep them out

  • Maintain thick, well-watered turf through summer
  • Mulch bare, sandy patches near walkways and beds
  • Fix drainage issues that leave soil dry and loose
New Hampshire context

Cicada killer wasps in New Hampshire

In New Hampshire, cicada killer females dig burrows in bare, sunny, well-drained soil through mid-to-late summer (roughly July–September), provisioning each with paralyzed cicadas for their larvae. Activity winds down well before the first hard frost, around October 19–29 in Manchester (NOAA), and burrows can simply be filled and the turf improved once activity stops for the season.
