All About Brooklyn Mice Pest Control Services (2026 Complete Guide)

The four types of mouse pest control services in Brooklyn

Most Brooklyn rodent calls fall into one of four service categories. Each has a different treatment plan, timeline, and pricing model.

1. Residential apartment treatment. Single apartments in multi-unit buildings, the most common Brooklyn mouse call. Treatment focuses on snap trapping in active runways, exclusion of entry points, and bait stations in wall voids where pets and kids can't reach. Full cycle: 4 to 6 weeks. See our guide to getting rid of mice in a Brooklyn apartment for the full method.

2. Residential brownstone and single-family treatment. Brownstones with basements, gardens, and multiple floors. Treatment expands to include the basement and exterior perimeter, with IGI CO2 burrow treatment for any garden burrow activity. Full cycle: 4 to 8 weeks depending on building size and exterior pressure.

3. Commercial treatment. Restaurants, bodegas, daycares, offices, warehouses. Includes IPM logbook, quarterly inspections, exterior bait station perimeter, and documentation for NYC DOH compliance. See our commercial mouse control guide for the emergency response approach, or the commercial prevention guide for ongoing programmatic work.

4. Exclusion and pest-proofing. Standalone service for sealing entry points in apartments, brownstones, and commercial properties. Often paired with treatment, sometimes purchased alone by buildings already on a maintenance program. Our pest-proofing service handles this.

Each service is available individually. Most cases get a combination of two or three.

Residential mouse pest control in Brooklyn

Residential work is the largest category of Brooklyn mouse calls. Two sub-types matter:

Apartments in multi-unit buildings:

• Typical infestation: 5 to 20 mice across kitchen, bathroom, and one or two other rooms
• Treatment: 6 to 12 snap traps placed along walls in active runways, 2 to 4 bait stations in wall voids or basement access points, exclusion sealing at 5 to 15 identified entry points
• Visit cadence: Initial inspection and trap placement, then 2 to 3 follow-up visits over 4 to 6 weeks
• Cost range: $300 to $550 for the initial treatment package
• Common challenge: shared-wall reinfestation from neighboring units or the basement. Often requires landlord coordination or building-wide treatment

Brownstones and single-family homes:

• Typical infestation: 10 to 50 mice plus possible Norway rat activity in the garden or basement
• Treatment: extensive trap placement across the building, exterior bait station perimeter, IGI CO2 for any garden or foundation burrows, comprehensive exclusion of the building shell
• Visit cadence: Initial inspection plus 3 to 4 follow-up visits over 6 to 8 weeks
• Cost range: $500 to $1,500 depending on size, severity, and exclusion scope
• Common challenge: garden Norway rat burrows feeding into basement entries. The IGI CO2 burrow treatment is the standard solution

Commercial mouse pest control in Brooklyn

Commercial work is more documentation-heavy than residential. The treatment products and methods are similar; the deliverables are different.

What's standard for a commercial account:

• IPM logbook with dated visit reports, monitor counts, products used (with EPA registration numbers), and treatment maps
• Exterior bait station perimeter installed at 30 to 50 foot intervals
• Interior monitoring with pheromone monitors or sticky cards at 20 to 40 foot intervals
• Quarterly visits (monthly during winter or active treatment)
• Documentation supporting NYC DOH compliance under Article 81

Pricing for commercial accounts varies significantly by property size and treatment frequency:

• Small café or office (under 1,500 sq ft): $150 to $300 per quarterly visit
• Mid-size restaurant or retail (1,500 to 4,000 sq ft): $250 to $500 per visit, often with monthly monitoring
• Large restaurant, warehouse, or multi-tenant building: $500+ per visit, often custom contracts

Emergency response (active infestation with a DOH inspection pending) costs more for the initial visit because of inspection time and exclusion work, then settles to the standard quarterly rate after.

Exclusion and pest-proofing in Brooklyn

Exclusion is the long-term lever. Sealing entry points stops the supply line. Done correctly, it eliminates the need for ongoing trapping and dramatically reduces the cost of maintenance.

Standard exclusion work in a Brooklyn apartment:

• Inspection of all interior and shared-wall entry points
• Copper mesh and silicone caulk for plumbing penetrations and small gaps
• Hydraulic cement for masonry openings
• 1/4 inch hardware cloth for vents and larger openings
• Brush-style door sweeps on exterior and hallway doors
• Foam outlet gaskets behind cover plates on shared walls

Brownstone exclusion adds:

• Foundation perimeter inspection
• Sealing of all exterior penetrations (gas, electrical, communications, plumbing)
• Roll-up door or basement door brush seals
• Crawl space and basement vent screening
• Garden burrow exclusion after IGI CO2 treatment

Commercial exclusion adds:

• Loading dock brush seals
• Exterior building shell audit
• Utility chase and service tunnel sealing
• Roof access and HVAC penetration sealing

Pricing for exclusion work typically ranges from $200 to $1,500 for residential and $500 to $5,000+ for commercial, depending on building size and scope.

IGI CO2 burrow treatment (OnGuard's outdoor differentiator)

For Brooklyn brownstones with garden Norway rat burrows or commercial properties with exterior burrow activity, the IGI CO2 system is OnGuard's differentiator.

What it is: A pressurized CO2 burrow treatment from Liphatech. USDA-organic-approved.

How it works: Compressed CO2 is applied directly into active burrow networks. The gas displaces oxygen in the burrow system, eliminating the rats inside without rodenticide.

Why it matters in Brooklyn:

• Norway rat burrows in brownstone gardens are a year-round problem in Park Slope, Bed-Stuy, Cobble Hill, Carroll Gardens, and most neighborhoods with rear-yard access
• Standard bait stations don't reach rats living in burrows
• CO2 is organic-approved and has no secondary poisoning concerns for pets, wildlife, or hawks and owls
• Single treatment usually eliminates the burrow population, followed by exclusion at the foundation to prevent re-colonization

When IGI CO2 is the right tool:

• Visible active burrow holes (2 to 4 inches wide, dirt mounded at entrance, fresh tracks)
• Burrows along foundations, garden beds, or trash storage areas
• Commercial properties with exterior burrow activity affecting interior spaces
• Multi-family buildings with rear gardens that connect to neighboring lots

When it's not the right tool:

• House mice (use traps and bait stations instead)
• Interior treatment (CO2 doesn't apply indoors)
• Burrow networks without visible active entries

What to expect during your first visit

First-visit expectations for a typical Brooklyn residential mouse call:

Before the visit:

• We'll ask about the scope (apartment vs brownstone), severity (how many mice, where you've seen them), and any specific concerns (kids, pets, asthma, allergies)
• We'll send a confirmation with the technician's name and arrival window
• Most calls before noon can be scheduled same-day

During the visit (typically 60 to 120 minutes):

• Full inspection of the apartment or building with flashlight, UV light, and mirror
• Identification of active runways, harborages, and entry points
• Discussion of findings and treatment plan
• Initial snap trap placement
• Bait station deployment in appropriate locations
• Initial exclusion notes and material plan
• Written treatment plan and pricing provided

After the visit:

• Daily trap checks (you or the technician depending on the package)
• 2 to 3 follow-up visits over 4 to 6 weeks
• Exclusion work completed during follow-up visits
• Final visit confirms no new activity and the apartment transitions to maintenance or off-contract

When you don't need a professional

A few situations where professional treatment isn't necessary:

• Single mouse, never seen another. Set 6 snap traps along the walls, check daily for a week. If no catches, you probably had a hitchhiker. Inspect for entry points and seal anything obvious.
• Light infestation caught early. 2 to 3 mice over a few days. Snap traps placed correctly along walls, peanut butter bait, daily checks. Exclusion of obvious entry points. Most cases clear in 2 to 3 weeks.
• Outdoor mice in a yard or garage without interior activity. Trap or bait outside, exclude entries to interior spaces.

When professional treatment is the better call:

• Trapping for 2 weeks with no decrease in catches or sightings
• Activity in multiple rooms or multiple floors of a brownstone
• Visible burrow activity outside
• Multi-unit building with shared-wall problems
• Anyone in the household with asthma, immunocompromised condition, or small children
• Commercial property with any rodent activity

FAQs about Brooklyn mice pest control services

Q: How quickly can OnGuard come out?

A: Same-day or next-day appointments across Brooklyn for active infestations. Call before noon for same-day in most cases.
