Who should I call for a wasp nest in New Hampshire?

Call a licensed commercial pesticide applicator holding NH Category F1 certification — the 'Industrial, Institutional, Structural, and Health Related Pest Control' credential under RSA 430. F1 is the correct category for structural stinging-insect work in NH. Anchor Pest Services holds license #782664 (category F1), is insured, and is a NEPMA member. NH law requires both applicator certification under Pes 300 and product registration under RSA 430:36 before any legal commercial wasp treatment. Before booking any exterminator, ask for their NH license number and category — any legitimate operator will provide it without hesitation.

Can Anchor come the same day in Manchester?

Often yes, scheduling permitting. Anchor is based at 700 Harvey Rd, Bldg 1, Manchester, NH 03103 and serves Manchester, Nashua, Concord, Derry, Bedford, Salem, Hudson, Amherst, Auburn, Goffstown, Hooksett, Litchfield, Loudon, Milford, and Bristol. Call (603) 785-0118 for current availability. Peak season (August through mid-September) is the busiest window; earlier and later in the season same-day availability tends to be higher. The flat one-time rate applies regardless of when you book.

Will Anchor kill honey bees?

No. Species confirmation is the first step of every service call, and confirmed honey-bee colonies are never treated. UNH Cooperative Extension notes that beekeepers 'do not like being called to remove a honeybee colony, only to discover that they are wasps' — correct identification before any treatment is the professional standard. If Anchor's technician identifies honey bees, the colony is referred to a licensed NH beekeeper for live relocation at no cost to you. Only confirmed pest wasps and hornets (paper wasps, yellowjackets, bald-faced hornets, European hornets) are treated.

Is Anchor licensed and insured?

Yes. Anchor holds NH commercial pesticide applicator license #782664, category F1 (Industrial/Institutional/Structural/Health-Related) under RSA 430, and is insured. Category F1 is specifically the NH certification required for structural stinging-insect control. Anchor is also a member of NEPMA (New England Pest Management Association). The products used — Tempo 1% Dust (EPA 432-1373), Drione (EPA 432-992), and Delta Dust (EPA 432-772) — are all confirmed on NH's 2026 product-registration list under RSA 430:36, coded 'G' (general use under commercial license).

Is the treatment safe for kids, pets, and my well or septic system?

The core treatment products are dusts applied directly into the nest void or wall cavity — they are not broadcast-sprayed in living space or poured into drains. EPA-registered product labels (Tempo, Drione, Delta Dust) specify void/crack-and-crevice use and prohibit water contamination. Anchor follows label law under its F1 license. As a precaution, keep people and pets out of the treatment area during application and follow the re-entry interval on the product label. The technician can walk you through specifics for your property. If stinging occurs before or after service, the Northern New England Poison Center is available 24/7 at 1-800-222-1222 for NH/ME/VT.

What products does Anchor use for wasp removal?

The core products are three EPA-registered insecticide dusts confirmed on NH's 2026 NHDAMF product-registration list: Tempo 1% Dust (cyfluthrin 1.0%, EPA Reg. 432-1373), Drione Insecticide (pyrethrins 1.0% + piperonyl butoxide 10% + amorphous silica gel 40%, EPA Reg. 432-992), and Delta Dust (deltamethrin 0.05%, EPA Reg. 432-772). A note on Delta Dust: its label restricts it from use on overhead nests — Tempo or Drione are the correct choices for aerial applications. Where appropriate, a supporting exterior perimeter spray (Onslaught, esfenvalerate 6.4% liquid, EPA 1021-1815) may be used for exterior/perimeter knockdown — note this is a liquid concentrate, not a dust, and its NH registration has not been independently confirmed; verify current status with NHDAMF (603) 271-3550.

Do I need a contract or ongoing service?

No. Anchor's Wasp & Hornet removal is a one-time service — no contract, no quarterly visits, no seasonal perimeter plan, no subscription. You pay one flat one-time rate for the single treatment, and the ~30-day re-treat guarantee covers you if activity resumes within that window. If you want to reduce the likelihood of future nests, the most effective step is physical exclusion — caulking and screening vents, cracks, and gaps in late winter or spring before queens scout for nesting sites. See /wasp-species/wasp-prevention for the full evidence-based spring-sealing guide.

What does a licensed wasp service call actually include?

A licensed Anchor technician follows an 8-step process: (1) species confirmation before anything else; (2) full PPE per label requirements; (3) EPA-registered dust injected at the nest entry or wall void; (4) 24–48-hour die-off window for the colony to self-contaminate; (5) nest knockdown and removal once activity stops; (6) sealing entry points against re-nesting; (7) optional supporting exterior perimeter spray where appropriate; (8) follow-up under the ~30-day re-treat guarantee. Treatment timing is set per the species, nest location, and access so the full colony is dosed — daytime, evening, or after dark; when a low-light approach is used, a red-filtered light helps because UNH Extension notes wasps cannot see red light well. The full field-ops detail is at /wasp-species/wasp-nest-removal.

Do repellents or fake wasp-nest decoys work instead of professional removal?

Not reliably. Physical exclusion (caulking, screening) is the only tactic with strong evidence for preventing new nests. Fake-nest decoys have weak, anecdotal support and any effect fades after early season. Peppermint and essential-oil sprays show brief deterrence in some lab studies but are not durable on an active nest in the field. Bait traps catch foraging workers but never the queen or brood — UNH Extension warns NH homeowners explicitly: 'Don't rely on yellow-jacket traps. They don't control northeastern U.S. species.' If you already have an active nest, no repellent or trap eliminates it. See /wasp-species/wasp-prevention for the full evidence-graded comparison and /wasp-species/wasp-trap for the trap-specific honest assessment.

Overview

Wasps in NH — here's who to call, what they're licensed to do, and how pricing works

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 does pricing work? 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 the nest entry or void so the entire colony is dosed. The full process is detailed at our sister page, /wasp-species/wasp-nest-removal.

As for pricing: one flat rate. Anchor charges a single flat one-time rate for Wasp & Hornet removal — no tiers, no contract, no per-nest upcharge, same rate regardless of season, colony size, or nest height. A ~30-day re-treat guarantee is included. Instead of a vague 'call for quote' range that shifts once someone shows up, Anchor holds to one flat one-time rate. Call (603) 785-0118 for your quote.

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') — one of the timing factors Anchor's F1-licensed technician weighs on each job.

Who you're hiring — Anchor's credentials, process, and flat one-time rate

Our field process

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.

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.

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.

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.

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.'

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.

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.

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

Return visit if needed within ~30 days

Anchor's flat one-time-rate 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.

EPA-registered products we use

All 4 products carry valid EPA registration numbers and are labeled for wasp and hornet control.

Tempo 1% Professional Dust Insecticide (Bayer/Envu)

NH Registered

Cyfluthrin 1.0% — NOT beta-cyfluthrin; confirmed from EPA-stamped label

In-void nest dust; labeled for wasps, hornets, bees, yellowjackets in wall voids, cracks, and crevices; for use only by pest management professionals and commercial applicators; label directs treating 'wasp and bee nests in the evening when the insects are less active and are inside the nest'

EPA Reg. #432-1373

Drione Insecticide (Bayer/Envu) — desiccant dust

NH Registered

Pyrethrins 1.0% + piperonyl butoxide 10.0% + amorphous silica gel 40.0%

Classic void and desiccant dust; drill-blow-reseal protocol; label: 'For best results check nests carefully one or two days after treatment to ensure complete kill, then remove and destroy nest'; industrial/commercial use only

EPA Reg. #432-992

Delta Dust / DeltaDust (Bayer/Envu) — waterproof dust

NH Registered

Deltamethrin 0.05%

Waterproof crack-and-crevice and void dust; LABEL RESTRICTION: 'Do not use this product to treat overhead nests' — use Tempo or Drione for aerial/overhead nests; not excluded from NH (CA/NY/AK/DC/MD only)

EPA Reg. #432-772

Onslaught Microencapsulated / Evercide Esfenvalerate 6.4% CS (MGK) — FLAGGED LIQUID, NOT DUST

Esfenvalerate 6.4% — liquid microencapsulated suspension concentrate, diluted with water before application

Supporting exterior/perimeter knockdown ONLY — crack-and-crevice spray and perimeter band around structure. NOT an in-void nest dust. NOT tied to any recurring plan. One-time supporting step only.

EPA Reg. #1021-1815

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 one-time rate. The license number, category, and product reg numbers were all provided in writing.

Scope: Flat one-time rate — no documentation surcharge

Scenario · Bedford

Eave nest — homeowner had received three vague phone estimates

A Bedford homeowner contacted three exterminator services and received vague phone estimates that all amounted to 'depends on the nest.' None would commit to a firm rate before seeing it in person. Looking for a straight answer, the homeowner found Anchor's flat one-time rate.

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

Scope: Flat one-time rate — all-in
