Licensed Wasp Exterminator in Manchester NH — Flat $399 Removal

TL;DR

In New Hampshire, wasp and hornet removal requires a licensed commercial applicator. Anchor Pest Services holds NH pesticide license #782664, category F1 (Industrial/Institutional/Structural/Health-Related under RSA 430), is a NEPMA member, and has operated from Manchester since 2017. One flat $399 covers a one-time Wasp & Hornet removal — species confirmed before any treatment, honey bees referred to a licensed NH beekeeper for live relocation rather than treated, and a ~30-day re-treat guarantee included.

Overview

Wasps in NH — here's who to call, what they're licensed to do, and what it costs

When you search 'wasp exterminator near me' in New Hampshire, you are really asking three questions at once: Is this business actually licensed? What will they do when they get here? And how much will it cost? Those three questions are the ones every competing pest-control page dodges. This page answers all three in plain terms.

Anchor Pest Services holds NH commercial pesticide applicator license #782664, category F1 — the 'Industrial, Institutional, Structural, and Health Related Pest Control' subcategory of Category F under RSA 430, administered by the NH Department of Agriculture, Markets & Food (NHDAMF) Division of Pesticide Control. NH law requires both applicator certification under Pes 300 and product registration under RSA 430:36 before any commercial stinging-insect treatment can legally happen. Anchor meets both requirements. The business has been operating from Manchester since 2017 and holds NEPMA (New England Pest Management Association) membership.

As for what the job includes: no product touches your structure until the technician confirms the species. That matters because a ground yellowjacket colony, an aerial paper-wasp nest, an enclosed bald-faced hornet nest, and a honey-bee colony each call for a different approach — and honey bees are never treated. Confirmed honey-bee colonies are referred to a licensed NH beekeeper for live relocation. For confirmed wasps and hornets, the licensed technician follows an 8-step field process built around EPA-registered dusts injected at dusk or after dark, when the entire foraging force is home. The full process is detailed at our sister page, /wasp-species/wasp-nest-removal.

As for the price: one number. Anchor charges a flat $399 for one-time Wasp & Hornet removal — no tiers, no contract, no per-nest upcharge, same price regardless of season, colony size, or nest height. A ~30-day re-treat guarantee is included. Industry-survey aggregators publish ranges from '$300 to $700 on average' (HomeGuide 2026) up to '$100 to $1,300' (Angi/This Old House 2026). Those ranges are real — but they are estimates compiled from many providers, none of whom quote you a number up front. Anchor's number is $399.

New Hampshire context

Licensed wasp control across southern and central New Hampshire

Anchor serves 15 cities across four counties from its Manchester base: Manchester, Nashua, Concord, Derry, Bedford, Salem, Hudson, Amherst, Auburn, Goffstown, Hooksett, Litchfield, Loudon, Milford, and Bristol — covering Rockingham, Hillsborough, Merrimack, and Strafford counties, with the Lakes Region served secondarily. All work is performed under NH license #782664, category F1, and uses products registered on NH's 2026 NHDAMF product-registration list. NH wasp season in the southern tier peaks August through mid-September, when paper wasp and yellowjacket colonies reach maximum size and defensiveness — and when most removal calls come in. Manchester-area colonies can stay active until the first hard frost, which falls around October 19 (50% probability) or October 29 (80% probability) per NOAA 1991–2020 normals, roughly two to three weeks later than Concord or Keene. That means Manchester homeowners can face active nests well into late October.

Species present in NH

  • Northern paper wasp (Polistes fuscatus)
  • European paper wasp (Polistes dominula)
  • Eastern yellowjacket (Vespula maculifrons)
  • German yellowjacket (Vespula germanica)
  • Bald-faced hornet (Dolichovespula maculata)
  • European hornet (Vespa crabro)

UNH Cooperative Extension notes that NH wasp activity peaks in late summer and advises treating nests after dark using a red-filtered flashlight ('wasps can't see red light well') — the protocol Anchor follows under its F1 license.

Cost drivers

  • Nest location (aerial/accessible vs. wall void vs. attic vs. underground) — moves the industry-survey estimates, NOT Anchor's flat $399
  • Colony size — moves industry estimates; Anchor's price is the same regardless
  • Species (yellowjackets vs. paper wasps vs. hornets) — moves industry estimates, especially yellowjackets
  • Season — many providers charge more in peak August–September; Anchor's flat $399 does not change
  • Number of nests — industry estimates sometimes charge per nest; Anchor's flat $399 covers the service call

Disclaimer

Industry-survey estimate based on national cost aggregators (HomeGuide, Angi, This Old House 2026). These figures represent ranges compiled from many providers across the US — they are NOT Anchor's pricing. Anchor Pest Services charges a flat $399, one-time, regardless of season, colony size, or nest location. Always confirm current pricing directly with any provider before booking.

Our 8-step field process

  1. 01
    1

    Species confirmation before any treatment

    5–10 min

    The technician identifies the species — paper wasp (Polistes), yellowjacket (Vespula), bald-faced hornet (Dolichovespula), European hornet (Vespa crabro), or honey bee — before opening any product. A ground yellowjacket colony, an aerial paper-wasp comb, and an enclosed bald-faced hornet nest each call for different tactics; honey bees are never treated and are referred to a licensed NH beekeeper for live relocation. Species misidentification is the single most common cause of DIY failure and the reason honey bees are needlessly killed.

  2. 02
    2

    Full PPE per label requirements

    2–5 min

    The applicator dons label-required protective equipment — gloves, eye protection, veil, and precautions against dust inhalation per product Safety Data Sheets — before approaching the nest.

  3. 03
    3

    EPA-registered dust injected at nest entry or wall void

    5–15 min

    A NH-registered labeled dust — Tempo 1% Dust (cyfluthrin 1.0%, EPA 432-1373), Drione (pyrethrins 1.0% + PBO 10% + silica gel 40%, EPA 432-992), or Delta Dust (deltamethrin 0.05%, EPA 432-772, not used on overhead nests per label) — is injected at the nest entrance or into the wall void. Dust is preferred over liquid sprays in voids because returning foragers track the active ingredient deep onto brood and the queen, reaching the whole colony rather than just surface workers.

    Delta Dust label: 'Do not use this product to treat overhead nests' — Tempo or Drione used for aerial and overhead applications. Onslaught (esfenvalerate 6.4% liquid, EPA 1021-1815) may be applied to exterior cracks and perimeter as a supporting spray; it is a liquid SC, not a dust, and its NH registration has not been independently confirmed — verify with NHDAMF (603) 271-3550.

  4. 04
    4

    Die-off window — 24–48 hours

    24–48 hours (no re-entry to treatment area)

    The colony is left to self-contaminate. All three NH-registered dusts direct checking the nest 'one or two days after treatment to ensure complete kill' before removal. The interval is biologically meaningful: foragers returning to the nest carry the dust to brood and the queen; newly hatched adults also contact residual product.

  5. 05
    5

    Knockdown and nest removal

    10–20 min

    Once activity has stopped, the nest is physically removed and discarded. Product labels specify: 'remove and destroy nest to prevent emergence of newly hatched insects.'

  6. 06
    6

    Entry-point sealing

    10–20 min

    Gaps, cracks, and voids used by the colony are caulked or screened to prevent re-nesting by future queens. UNH Extension recommends caulking and screening vents, cracks, and windows as part of any professional wasp service.

  7. 07
    7

    Exterior knockdown — supporting, optional

    5–15 min

    Where appropriate, a supporting exterior perimeter spray (esfenvalerate, Onslaught, EPA 1021-1815 — a liquid microencapsulated concentrate, not a dust) is applied to cracks, crevices, and a perimeter band around the structure. This is a one-time support step, not a recurring treatment. NH registration for Onslaught has not been independently confirmed — flagged; verify with NHDAMF Division of Pesticide Control, (603) 271-3550.

    Onslaught is a liquid SC, never an in-void nest dust. Not tied to any recurring plan.

  8. 08
    8

    Follow-up under ~30-day re-treat guarantee

    Return visit if needed within ~30 days

    Anchor's flat $399 service includes a ~30-day re-treat guarantee. If wasp activity resumes at the treated site within approximately 30 days, the technician returns at no additional charge. Contact Anchor at (603) 785-0118.

DIY OK if…
  • The nest is a small (golf-ball size or smaller), early-season, exposed paper-wasp umbrella comb on a flat surface — UNH Extension notes some early colonies 'can just be squashed against the eaves with a board'
  • You can treat it well after dark (≥2 hours) with a red-filtered light — UNH notes wasps cannot see red light well, and treating at night brings the full foraging force home
  • No one in the household has a known sting allergy
  • The nest is not in a wall void, attic, or any enclosed cavity
  • You can retreat immediately after treatment and stay clear for a full day — UNH: 'After spraying, don't linger nearby. Walk away immediately'
Call a pro if…
  • The colony is inside a wall void, attic, soffit, or any enclosed cavity — sealing it traps workers who then chew inward through drywall into living space
  • The species is a yellowjacket or hornet — larger colonies, more aggressive defense, often hidden in hard-to-reach locations
  • The nest is large, high, or requires working within one to two feet of an active colony
  • Anyone in your household is allergic to wasp venom — UNH: 'don't try it yourself if you are highly allergic to stings. Call an exterminator instead'
  • You cannot confirm the species and risk treating honey bees that should be relocated

Why DIY fails

  • Surface aerosol sprays agitate void-nesting colonies without reaching the queen or brood — the colony persists or shifts deeper into the wall; EPA-registered dusts that foragers track to the queen are far more effective in voids
  • Sealing a live wall-void entry traps workers inside who then chew through drywall into living space — always treat first, seal after the colony is dead
  • Shop-vacs agitate the colony and release live, stinging wasps rather than eliminating them
  • Boiling water on a wall-void colony does not penetrate to the nest, scalds the applicator, and soaks drywall and insulation
  • Gasoline and fire: a homeowner in Grand Blanc Township, Michigan — not NH — attempted to kill garage wasps with a bug/smoke bomb, ignited the structure, and burned it to the ground while stored fireworks exploded (CBS News/CNN, 2017). No gasoline, fire, or smoke bombs near a wasp nest, ever

Illustrative scenarios

Composite examples drawn from typical southern-NH calls — not real homeowners.

Scenario · Manchester

Multi-unit rental property, wall-void yellowjacket colony

A Manchester landlord needed documentation that a licensed commercial applicator had treated a stinging-insect problem at a multi-unit property — the property manager required proof for insurance and tenant records.

Outcome: Anchor's F1 license documentation, treatment records, and EPA-registered product logs satisfied the requirement. Flat $399, one-time. The license number, category, and product reg numbers were all provided in writing.

Range: Flat $399 one-time — no documentation surcharge

Scenario · Bedford

Eave nest — homeowner had received three 'call for quote' estimates

A Bedford homeowner contacted three exterminator services and received vague phone estimates ranging from '$200 and up' to 'depends on the nest.' None would give a firm number before seeing it in person. Looking for a published price, the homeowner found Anchor's flat $399.

Outcome: One technician visit, species confirmed (European paper wasp), nest treated and removed, flat $399, ~30-day re-treat guarantee included. No surprise upcharge.

Range: Flat $399 — one-time, all-in
