You stop dreading your own kitchen. You stop finding them behind the stove, under the fridge, or worst of all in the bathroom at 2 a.m. That’s the real outcome. Not a treatment certificate on your counter. An actual end to the problem.
In Richmond Hill, cockroach infestations don’t always start where you think they do. A lot of the homes here especially in the 11418 and 11419 ZIP codes are converted Victorian row houses that are over a century old. Shared walls, aging plumbing, and original wood framing give cockroaches more entry points and travel corridors than most people realize. Treating your unit alone, while the problem lives in the wall cavity between you and your neighbor, is why so many DIY attempts fail.
The dense stretch of roti shops, bakeries, and groceries along Liberty Avenue creates a persistent pest pressure that radiates into the surrounding residential blocks. If you’ve been dealing with a recurring cockroach problem and you live near that corridor, that context matters and it changes how the treatment needs to be approached. Getting it right the first time means fewer callbacks, less disruption to your household, and a home that stays clear.
We’re a family-owned business based in Brooklyn, founded over 40 years ago by Richard Kourbage Sr. Richard Kourbage Jr. joined in 1987, and we’ve been operating continuously ever since through every regulatory change, every housing cycle, and every shift in the communities we serve across the five boroughs, including Richmond Hill and the surrounding neighborhoods in Queens Community Board 9.
Our team collectively brings more than 100 years of hands-on pest control experience. That’s not a number we throw around to sound impressive it means your technician has likely seen your exact situation before, in a building just like yours, on a block not far from yours. We hold a consistent A+ rating with the Better Business Bureau of New York State, and every treatment we perform uses only NYS Department of Environmental Conservation registered materials.
We serve homeowners, renters, property managers, and commercial clients throughout Richmond Hill, Woodhaven, Kew Gardens, and the surrounding neighborhoods. If you’re a landlord managing a converted multi-family on a tree-lined block in North Richmond Hill, or a restaurant owner on Liberty Avenue facing a DOH inspection, we’ve worked with clients in both situations and we know what each one actually requires.
It starts with a proper inspection, not an assumption. Before anything gets applied, a technician walks the space kitchen, bathroom, basement, utility areas and identifies what species you’re dealing with, where they’re coming from, and what’s allowing them to stay. In Richmond Hill’s older homes, that often means checking plumbing penetrations, shared wall voids, and basement access points that a less thorough inspection would completely miss.
From there, the treatment is built around what was actually found. German cockroaches the small, fast ones you see in kitchens and around appliances respond best to targeted gel bait and crack-and-crevice treatment, not broadcast spraying. American cockroaches, the large ones Richmond Hill residents often call “waterbugs,” typically need drain treatment and entry-point sealing to stop them from emerging through the sewer system during heavy rain. These are two different problems that require two different approaches. Applying the wrong one wastes your time and your money.
After the initial treatment, we’ll walk you through what to expect over the following days and whether a follow-up visit makes sense for your situation. For property managers or building owners dealing with cockroach infestation across multiple units, we can coordinate treatment building-wide which is often the only way to fully resolve a problem in Richmond Hill’s attached row house stock. We also offer ongoing maintenance schedules monthly, every other month, or quarterly so the problem doesn’t come back six months later.

Every cockroach pest control service in Richmond Hill starts with a full inspection not a walk-through glance, but an actual assessment of where the infestation is, how it got there, and what’s sustaining it. From there, treatment is applied using NYS DEC registered materials by certified technicians who are licensed, bonded, and fully insured. You’ll know exactly what’s being used, how long to stay out of treated areas, and what precautions are needed especially important in households with children, elderly family members, or pets.
For residential clients in Richmond Hill’s converted Victorian homes, that often means gel bait placement in kitchens and bathrooms, crack-and-crevice treatment along baseboards and plumbing penetrations, and drain treatment if waterbugs are part of the problem. For commercial clients particularly food businesses along Liberty Avenue or Jamaica Avenue we understand the NYC Department of Health inspection process and what it takes to get back into compliance. A cockroach sighting during a DOH inspection results in critical violations that can directly affect your letter grade. That’s not a situation where you want to experiment with a company that doesn’t know the process.
We also issue Demolition Clearance Certificates to the NYC Department of Health, which is relevant for Richmond Hill property owners going through renovation or demolition work. And for qualifying customers, we offer a 10% senior discount because a lot of the long-time homeowners in this neighborhood have been here for decades and deserve straightforward, honest service at a fair price.
Those are American cockroaches what most people in Richmond Hill and across Queens call “waterbugs.” They live in the sewer system, not in your home, and they come up through floor drains, basement sump pits, and aging utility penetrations when conditions push them upward. In Richmond Hill’s older homes many of which were built between 1890 and 1915 the basement plumbing and drain infrastructure is often original or partially replaced, which means there are more gaps and entry points than you’d find in a newer building.
This problem tends to get worse after heavy rain events, when the sewer system gets overwhelmed and cockroaches migrate upward to escape. It’s not a sign that your home is dirty. It’s a structural and seasonal issue that’s specific to South Queens neighborhoods with aging infrastructure. The fix involves treating the drains directly and sealing the entry points where they’re getting in not just spraying the surface. If you’re only seeing them occasionally and they’re always large and reddish-brown, that’s almost certainly what you’re dealing with.
Yes and in Richmond Hill’s attached row houses and converted Victorian multi-family buildings, this is one of the most common reasons a cockroach problem keeps coming back after treatment. German cockroaches travel through shared wall voids, plumbing chases, and the spaces around pipes and electrical conduits that run between units. If a neighboring unit has an active infestation and yours doesn’t get treated at the same time, the population simply relocates and rebuilds.
This is why treating a single unit in an attached building is often a short-term fix. The more effective approach is coordinating treatment across the affected units ideally with the landlord or property manager involved. Under NYC Administrative Code Section 27-2018, building owners are legally required to maintain apartments free of pests. If your landlord isn’t addressing the problem building-wide, tenants have the right to file a complaint through 311. We work with property managers throughout Richmond Hill and Queens Community Board 9 to handle multi-unit infestations the right way treating the building-level problem, not just the unit-level symptom.
German cockroaches the most common species in NYC apartment buildings have developed significant resistance to the synthetic pyrethroid sprays sold in most hardware stores. When you spray them, the ones that survive pass that resistance on to their offspring. Over time, the spray stops working almost entirely, and you’ve also scattered the population deeper into wall voids and appliance motors where it’s even harder to reach them.
Professional cockroach control uses a different approach. Gel bait treatments work by letting cockroaches carry the bait back to the harborage site, where it spreads through the population including the ones you never see. Crack-and-crevice treatments target the specific areas where cockroaches actually live, rather than the open surfaces they cross. The combination is categorically more effective than a can of spray, and it doesn’t drive the infestation further into the building. If you’ve been spraying for weeks and still seeing cockroaches every morning, the spray isn’t the answer.
For most residential treatments in Richmond Hill, you’ll need to be out of the treated areas for a few hours typically two to four hours after application, depending on what’s being used and where. Your technician will walk you through the specific re-entry time before anything is applied, and will tell you exactly what precautions to take, especially if you have young children, elderly family members, or pets in the household.
The treatment itself usually takes between one and two hours for a standard apartment or single-family home, though larger multi-family buildings or heavily infested properties can take longer. Because many Richmond Hill residents have long commute times the neighborhood’s average is around 66 minutes each way we work to schedule efficiently so the treatment doesn’t require you to take a full day off work. After the visit, you may see increased cockroach activity for a few days as the population is disrupted. That’s normal. It typically settles within one to two weeks as the treatment takes full effect.
Cockroaches carry pathogens on their bodies and in their droppings bacteria that can contaminate food surfaces and contribute to food-borne illness. But the health concern that gets less attention is cockroach allergens. Cockroach droppings, shed skins, and saliva are documented asthma triggers, particularly for children. Queens has historically high rates of childhood asthma, and cockroach allergen exposure in the home is one of the contributing factors that researchers have consistently identified.
In Richmond Hill’s multi-family buildings especially the converted Victorian row houses where multiple households share plumbing and wall spaces a cockroach infestation in one unit can spread allergens throughout the building, not just the unit where the visible population is concentrated. If someone in your household has asthma or respiratory sensitivities, getting the infestation fully resolved not just reduced matters more than it might seem. Every treatment we perform uses NYS DEC registered materials applied by certified technicians, so you’re not trading one health concern for another.
Yes we offer a 10% senior discount on cockroach pest control services. Richmond Hill has a significant population of long-time homeowners who have lived in and maintained their properties for decades many of them in the Victorian and Edwardian homes that define the neighborhood’s historic character. These are people who’ve invested their lives in their homes, and pest control should be accessible to them without being a financial burden.
If you or a family member qualifies, just mention it when you call. The discount applies to residential cockroach control services and can be combined with our standard service offerings, including initial treatment and ongoing maintenance schedules. For homeowners in the 11418 or 11419 ZIP codes who want to stay ahead of the problem rather than dealing with a full infestation every summer a recurring maintenance plan combined with the senior discount is often the most cost-effective approach over time.
