A mouse problem in Brooklyn is usually solved by finding where the mice are nesting, closing the small gaps they use, and using traps and lockable bait stations in the right places. Mice can live entirely indoors, so unlike rats, they don't need a garden or a tree to survive. One pregnant female in a warm cupboard is enough to start a real problem.
Where Brooklyn mice turn up
Older family homes
Houses that have stood for decades develop the kind of gaps a mouse can use: worn seals on outside doors, holes where old pipes were removed, cracks behind built-in kitchen units and spaces under the floor. A mouse can squeeze through a gap about the width of a pencil, so even a well-kept older home has plenty of options.
Flats and rented rooms
Closer to the university, some homes are let out as rooms or split into units. More people, more food stored in bedrooms and more coming and going all help mice. In shared buildings, the mice also move between units through service ducts and gaps around pipes, so one tenant setting traps rarely solves it.
Offices in converted houses
A staff kitchen with a toaster, a bin and a drawer of biscuits, plus a storeroom of archive boxes nobody opens, is close to perfect for mice. Shredded paper makes excellent nesting material, and a building that's empty at night gives them free run of the place.
Signs it's mice and not rats
- Small, dark droppings like grains of rice, scattered in drawers, cupboards and along skirting
- Packets of rice, pasta, cereal or pet food nibbled open
- Light scratching inside walls or behind kitchen units, rather than heavy running in the roof
- Shredded paper, tissue or fabric tucked into a corner
- A musty smell in a closed cupboard
If what you're hearing sounds heavier and comes from overhead, look at our page on roof rats in Brooklyn instead.
How we get rid of mice
We start with an inspection: kitchen units, pantry, behind and under appliances, storerooms, geyser cupboards, the roof and any outbuildings. Mice tend to stay within a few metres of their nest, so the spread of droppings tells us a lot. We then use traps where they travel indoors and lockable bait stations where bait is appropriate, away from children and pets. Tracking powder can help us confirm their routes in walls and service ducts. Finally, we show you the entry points to close, which in older Brooklyn homes are usually gaps under doors, around pipes and behind kitchen units.
For offices, we can put the building on a scheduled monitoring contract so the stations are checked and recorded regularly.
What people get wrong about mice
Assuming that one mouse means one mouse. By the time you see one in daylight, there are usually several nesting nearby. Catching the first one and stopping there is how a small problem becomes a big one a month later.
A second mistake is storing dry food in its original packaging. Mice chew through cardboard and thin plastic easily. Moving flour, cereal and pet food into glass or hard plastic containers removes a lot of the reason they're there, and it helps with pantry insects too. Our page on pantry pests in Brooklyn covers the weevils and moths that often turn up at the same time.
A tip for older Brooklyn kitchens
Pull out the stove and the fridge. In many older houses, the gap behind those appliances leads to the space under the kitchen units and into the walls, and it's where mice nest, feed and travel. Sealing the gaps around the pipes and cables back there with steel wool and filler makes a real difference.
What does mouse control cost?
For most homes, it's a modest job: an inspection, traps and stations, and a follow-up. The cost rises with the size of the property, the number of units in a shared building and whether an office wants ongoing monitoring. Honestly, if you've seen a single mouse and no droppings since, a few snap traps baited with peanut butter may be enough. If they keep appearing, call us.
See our mouse control work across Pretoria for more detail on the methods, or our mouse control in Lynnwood if you're just over the boundary. Everything else we handle in the suburb is on the Brooklyn pest control page. We're SAPCA registered, with 25 years in the trade, and our 3-month guarantee means that if mice return in that period, we return too.

Questions we get asked
How small a gap can a mouse get through?
Roughly the width of a pencil. That's why older homes, with worn door seals and gaps around pipes, are so easy for mice to enter.
Are the mice coming from my neighbour's unit?
In shared buildings, often yes. Mice travel through service ducts and gaps around pipes, which is why treating the whole building works better than one unit.
Do ultrasonic repellers work?
Not reliably. Mice get used to the sound quickly. Traps, bait stations and closing gaps are far more effective.
Is it safe to use bait in a kitchen?
We use traps in food areas and keep bait in lockable stations elsewhere, so there's no loose bait near food, children or pets.
Why do mice like our office storeroom?
It's quiet, dark and full of paper and cardboard for nesting, usually close to a kitchen with food. Moving boxes off the floor and checking them regularly helps.
How long until the mice are gone?
In most homes activity drops within one to two weeks. Shared buildings and offices take longer if mice keep coming in from neighbouring units.
