GUIDE · UPDATED JUNE 2026 · RE-VERIFIED QUARTERLY

The best exterminators in Park Slope, by what's in your walls

By Victor S. · Founding editor of The Park SloperUpdated June 6, 2026 · ~2,400 words · 10 min read

Something's in the wall, or scuttling across the kitchen at 2 a.m., or worse, you've spotted a bite pattern on the sheets. In a borough where the rat is practically a civic mascot and the brownstones share walls, a good exterminator is less a luxury than a fact of life.

Six picks, by what you're actually dealing with. Each one a New York State DEC-registered pesticide business, the credential every company applying pesticides for hire in New York is required to hold, and that we confirmed currently active in the state registry.

Best for rodents (mice & rats) without the upsell

Alley Cat Exterminating Co Inc

$$ · mice & rats · owner-run, no upsell

The pick when you've got mice or rats and want someone straight with you about it. Alley Cat is an owner-run Brooklyn firm (Don Clark) that neighbors on Park Slope Parents praise for the opposite of a hard sell: thorough work, child-safety care, text-back availability, and at least one report of refusing payment when results weren't guaranteed. It handles rats, mice, bed bugs, and general pests, and its DEC registration covers structural and rodent control.

Skip if: You need a big-name firm with a 24/7 dispatch line and an online portal, or a commercial contract. Alley Cat is a small owner-run operation, which is the point, but it's not a corporate service desk.

Best for eco-conscious households with kids and pets

Alternative Pest Control Inc

$$ · eco-friendly · kid & pet safe

The pick when you want the treatment thought through around a toddler and a dog. Alternative Pest Control has worked NYC since 1992, and its owner, Ernie Schicchi, is an Associate Certified Entomologist and rodent specialist. Brownstoner's Home Pros directory praises it as knowledgeable, professional, and genuinely considerate of kids and pets in what it puts down. It covers insects, bed bugs, and rodents, and its DEC registration includes termite control.

Skip if: You want a same-day, lowest-bid one-off and don't care about the products used. Alternative's edge is a careful, entomologist-led approach, which isn't built for a race to the bottom on price.

Best established local with a dedicated Park Slope service area

Ecology Exterminating Service Corp

$$ · since 1973 · low-toxic methods

The longtime local. Ecology has run since 1973 and keeps a dedicated Park Slope, Clinton Hill, and Fort Greene service page, so it knows the brownstone-block layout. Park Slope Parents call it reasonably priced, efficient, and careful to avoid dangerous chemicals. It handles the full Brooklyn roster (bed bugs, rats and mice, roaches, termites, ants, bees and wasps, even humane bird removal) and leans on low-toxic methods and Xcluder rodent exclusion.

Skip if: You want a boutique, single-specialist outfit. Ecology is a broad, established general exterminator; if you specifically want, say, a bed-bug-only specialist, there are narrower picks here.

Best for bed bugs and sealing entry points (exclusion work)

Evergreen Eco Pest Control Inc

$$ · bed bugs · finds the cracks

The pick when the real fix is finding where they're getting in. Evergreen handles bed bug detection and extermination plus mice, and Park Slope Parents (including a 2026 review) praise it as discreet, professional, and thorough at locating cracks and entry points, then recommending the repairs. Neighbors note it returned twice for free and stood behind a job guarantee. It's eco-positioned, using biodegradable, water-soluble products.

Skip if: You want the absolute lowest one-time spray and aren't interested in the exclusion (sealing) work. Evergreen's value is in finding and closing entry points, which is the part that actually keeps them out.

Best for the stubborn case after other exterminators failed

M & M Pest Control Inc

$$$ · the hard cases · documented & guaranteed

The pick when someone else already struck out. Park Slope Parents credit M & M with solving persistent problems other exterminators couldn't, through comprehensive entry-point sealing, documentation, and work guarantees. It handles bed bugs, mice, moths, and ants with pet-friendly treatments. It's based in Long Island City and travels to Brooklyn, and neighbors are candid that it's expensive. When the cheaper route already failed, the effective one tends to be worth it.

Skip if: You want the cheapest option for a routine, first-time problem. M & M is the heavy artillery for stubborn cases; for a single mouse sighting in an apartment, it's more than you need.

Best closest-to-Park-Slope independent for bed bugs

NYC Pest Control & Trapping, Inc.

$$ · bed bugs · 5-star Yelp intake

The pick for a Brooklyn independent that's easy to reach when a bed-bug problem has you rattled. The firm (which markets as New York Pest Control) carries 5 stars across 23-plus Yelp reviews, with intake staff repeatedly praised for empathy through what is a genuinely awful ordeal. It's profiled as a Brooklyn bed-bug specialist. Confirm the current service address when you call, since the public registry lists a different Brooklyn zip than the firm's marketed location.

Skip if: You want a large firm with multiple crews on call, or a one-stop for termites and wildlife. This is a bed-bug-focused independent; match it to the problem it's known for.

In short: Alley Cat for rodents without the upsell, Alternative for eco-conscious homes with kids and pets, Ecology for an established local that knows the Slope, Evergreen for bed bugs and sealing entry points, M & M for the case nobody else could crack, and NYC Pest Control & Trapping for a close-by bed-bug independent.

What does an exterminator cost in Park Slope?

Pest-control pricing depends on the pest, the size of the place, and how many visits the job really needs, so the honest answer is a range, not a number. Across NYC, a typical pest-control service runs about $257, usually $163-$353, with individual visits commonly $110-$290 (Angi, 2026).

JobTypical NYC / Brooklyn range
Single service visit~$110-$290
One-time mouse job~$150-$250 (near $200 for a single apartment)
Bed bugs (whole home)~$600-$740, usually over multiple visits
Bed bugs (one-bedroom, Brooklyn list price)from ~$750, with a guarantee
One-time one-family treatment (Brooklyn)~$425 (rodents included)
Monthly recurring plan~$89-$249

Two things to budget for honestly. Bed bugs and rodent exclusion are multi-visit by nature: a single spray rarely ends it, and one NYC exterminator's published price guide (Private Exterminator, 2025) puts bed-bug jobs in the high hundreds precisely because they take repeat treatments. And one Brooklyn firm's published price list (Abolish Pest Control, 2026) starts a one-family treatment around $425 and bed bugs from about $750 for a one-bedroom, plus $100 per extra bedroom. A phone quote with no inspection, especially for bed bugs, is a placeholder at best. The real number comes after someone has seen the problem.

Frequently asked questions

How much does an exterminator cost in Park Slope?
Cite the range, not a single number. NYC pest-control guides put a typical service around $257, usually $163-$353, with individual visits commonly $110-$290 (Angi). A one-time mouse job runs about $150-$250, near $200 for a single apartment trap-set, more for a whole house. Bed bugs are the big one: roughly $600-$740 to clear a home, almost always over multiple visits, with specialized treatments spanning $150-$1,250 by scope. Brooklyn list pricing puts a one-time one-family treatment around $425 and bed bugs from about $750 for a one-bedroom. Rodent exclusion and bed-bug work are multi-visit by nature, so budget for the follow-ups.
Do exterminators in New York need a license?
Yes. Any business that applies pesticides for hire in New York must hold a commercial pesticide-business registration from the New York State Department of Environmental Conservation (DEC), and individual applicators must be certified. This is the consumer-protection credential for the trade: it means the company is on the state's books and accountable for what it puts in your home. Every pick on this list was matched, by legal business name, to a currently active DEC registration. A handyman 'who knows a guy with spray' is not a registered pesticide business, and hiring one carries real risk.
How do I verify an exterminator's DEC pesticide-business registration?
Look them up in the state's public registry. New York's DEC publishes a 'Currently Registered Pesticide Businesses' dataset on the state open-data portal, searchable by business name. Confirm the legal business name matches the company you're hiring (not a similar one), that the status reads currently registered, and that the expiration date is in the future. Ask for the registration number and check it yourself. It takes a couple of minutes. Every pick here was verified this way, and the registration numbers are on each card.
What are the red flags when hiring an exterminator?
A few. No DEC registration number when you ask for one, or a number that doesn't match the company name in the state registry. Pressure to sign a long recurring contract before anyone has seen the problem. A quote given over the phone with no inspection, especially for bed bugs. Vagueness about what product is being applied around kids or pets. And no written guarantee on jobs (rodents, bed bugs) that genuinely need follow-up visits. A registered, reputable exterminator inspects first, names the product, and stands behind multi-visit work.
What pests are most common in Park Slope brownstones?
The Brooklyn staples. Rats and mice top the list, especially where old buildings, gardens, and construction meet; the brownstone rat is practically a neighbor. Bed bugs travel between attached homes and apartments and are the most stressful to clear. Roaches, carpenter ants, and termites show up in older wood-and-masonry buildings, and raccoons occasionally set up in a cornice or under a roofline. Attached row houses share walls, so a problem next door can become yours. Sealing entry points (exclusion) matters as much as treatment here.
Should I expect a guarantee or follow-up visits?
For rodents and bed bugs, yes. Those problems are rarely solved in one visit: rodent control pairs treatment with sealing entry points, and bed bugs almost always need multiple treatments to break the cycle. Several picks here (Evergreen and M & M among them) are praised specifically for documentation, entry-point sealing, and standing behind the work with return visits. Ask up front what the job includes, how many visits are expected, and what the guarantee covers before you agree to anything.

How do you verify an exterminator's DEC registration?

Here's the consumer-protection rule worth knowing before you let anyone spray in your home: in New York, any business that applies pesticides for hire must hold a commercial pesticide-business registration from the state Department of Environmental Conservation (DEC), and the individuals doing the work must be certified applicators. This isn't optional, and it isn't the same as a generic business license. It's the credential that puts a company on the state's books and makes it accountable for what it puts in your walls.

To check it: search the DEC's "Currently Registered Pesticide Businesses" dataset on the New York State open-data portal by business name. Confirm three things. The legal business name matches the company you're actually hiring, not a similarly-named one (this trips people up: "New York Pest Control" and "NYC Pest Control & Trapping" are not automatically the same entity, and there are unrelated copycats out there). The status reads currently registered. And the expiration date is in the future.

Why it matters: the registration ties a company to the state's enforcement record and confirms it's legally allowed to apply pesticides near your kids and pets. A handyman with a can of something from the hardware store is not a registered pesticide business. Every pick on this list was matched, by legal name, to a currently active DEC registration, and each registration number sits right on the card. Ask any exterminator for theirs and look it up. It takes two minutes.

What should you ask before hiring an exterminator?

Five questions sort a registered pro from a risky spray-and-pray:

  1. What's your DEC pesticide-business registration number? (Then look it up.)
  2. Will you inspect before you quote, especially for bed bugs?
  3. What product are you applying, and is it safe around kids and pets?
  4. How many visits does this job usually take, and what's the guarantee?
  5. Do you handle the sealing (exclusion) work, or just the treatment?

For rodents and bed bugs, that last pair matters most. Sealing entry points and returning for follow-ups is the difference between a problem solved and a problem postponed.

How did we vet these exterminators?

Two filters. Community signal: every pick here turns up where Park Slope neighbors trade names for this stuff. That means Park Slope Parents, the Brownstoner Home Pros directory, and Yelp, plus each company's own site. The registration: we matched every name, by legal business name, to a NYS DEC pesticide-business registration reading currently registered in the state's public dataset, with a future expiration (the earliest is February 2027). All six sit in DEC Region 2, the five boroughs, and serve Brooklyn.

A few names neighbors love didn't make it, and the reason is the whole point of this guide. Cobble Hill Exterminators, Essential Pest Control, and a Brooklyn "Arrow" listing all carried real community goodwill, but none could be matched to a confirmed DEC pesticide-business registration in the state dataset. Absence from the registry means we can't confirm the company is legally registered to apply pesticides, so they were held back rather than listed on reputation alone. Two practical notes worth a phone call: the state registry has no street addresses (city and zip only), so the addresses and service areas here come from each company's own site. And for NYC Pest Control & Trapping, the registry lists a different Brooklyn zip than the firm's marketed Gowanus location, so confirm the current service address when you call.

This isn't a hands-on test, and nobody pays to be on this list. Written by Victor S., founding editor of The Park Sloper. Park Slope is our neighborhood and the only one we cover. Last refreshed June 6, 2026; next refresh September 2026.
