Mouse Control in Brooklyn, NY
Mouse infestations are one of the most common wildlife complaints in Brooklyn — and one of the most persistent. The borough's aging brownstones and row houses, shared wall cavities, and proximity to dense commercial food sources make mice a year-round challenge. We eliminate the infestation and seal your home so they can't come back.
Why Brooklyn Has Persistent Mouse Problems
Three factors combine to make Brooklyn a particularly difficult environment for mouse control: old buildings, attached construction, and commercial food pressure.
Old Buildings: Brooklyn's brownstone and row house stock was built primarily between 1880 and 1940. After 80–140 years of settling, these buildings have accumulated gaps at every foundation joint, utility penetration, and door frame. A house mouse needs only a 1/4-inch gap to enter — and Brooklyn's aging building envelopes have thousands of them.
Attached Construction: In Brooklyn's attached row houses and brownstones, mice travel freely through shared wall cavities and floor joists. An infestation that appears to be coming from your kitchen may actually be entering through a basement crack in the unit three doors down and traveling through shared structural voids to your unit.
Commercial Food Pressure: Brooklyn's vibrant restaurant and food retail scene — concentrated on Smith Street, Fifth Avenue, Flatbush Avenue, DeKalb Avenue, and dozens of other corridors — sustains enormous outdoor mouse populations on surrounding residential blocks. As temperatures drop in fall, this outdoor population pushes hard into residential buildings.
High Mouse Activity Neighborhoods

Signs of Mice in Your Brooklyn Home
Droppings in Kitchen Cabinets
Mouse droppings — rice-sized, dark brown, pointed at both ends — in kitchen cabinets, behind the stove, or in pantry areas confirm active infestation. Fresh droppings are soft and dark; older ones are hard and gray.
Scratching in Walls After Midnight
Mice peak in activity between midnight and 4am. Light scratching in walls, especially in kitchen and bathroom areas, is a classic Brooklyn brownstone complaint — mice traveling through wall voids between units.
Gnawed Food Packaging
Small, ragged holes in cereal boxes, cracker packages, or bread bags in your pantry or cabinets indicate mice accessing food. Unlike rats, house mice gnaw small, irregular holes.
Shredded Material Behind Appliances
Mice nest in warm, hidden locations. Shredded paper, insulation, or fabric found behind refrigerators, under stoves, or in lower cabinet corners indicates active nesting.
Musty Smell Under Sinks
An ammonia-like smell under sinks, in lower cabinets, or in closets indicates mouse urine accumulation. In attached brownstones, this smell often appears suddenly when mice migrate from neighboring units.
Grease Marks Along Baseboards
Mice travel the same routes repeatedly, leaving faint gray smear marks from body oils along baseboards and wall edges. Dark trails along lower walls are established mouse highways.
Our Brooklyn Mouse Control Process
Whole-Unit Inspection
We inspect every area — kitchen, bathrooms, basement access, utility areas, and any shared wall spaces accessible for inspection. We identify droppings, gnaw marks, grease trails, and nesting sites, then map travel routes.
Targeted Trap Placement
We place snap traps and bait stations along identified travel routes — against wall edges, behind appliances, inside lower cabinets, and in basement areas. Professional placement achieves capture rates far above what homeowners achieve independently.
Exclusion — This Is the Key Step
Without sealing entry points, trapping is a treadmill. We seal every identified gap — foundation cracks, pipe penetrations, door threshold gaps, shared wall openings — using steel wool, galvanized hardware cloth, and commercial caulk.
Follow-Up & Confirmation
We return to check activity levels, refresh traps and bait, and identify any remaining entry points. We stay with the job until the infestation is fully eliminated.
Written Prevention Plan
We provide specific recommendations for your Brooklyn home — proper food and compost storage, gap identification, building management recommendations for multi-family brownstones — to minimize future risk.
Mouse Control Cost in Brooklyn
Most Brooklyn residents spend $600–$1,400 total. Free inspections, no-obligation quotes.
