Rat control in Brussels: rats & mice

Rats and mice move fast into a cellar, kitchen or attic as soon as they find food and shelter. The longer an infestation lasts, the harder it is to stop: Klaxxi steps in at the first signs to prevent damage and health risks.

Signs of infestation

Droppings along skirting boards, scratching noises at night, gnawed cables or packaging, grease marks on walls, a persistent ammonia smell: all signs of a rodent infestation you shouldn't let take hold.

Our method

A three-step intervention, designed to prevent any recurrence.

01
A full inspection of the building to identify entry points and travel routes.
02
Traps and secure bait stations installed out of reach of children and pets.

Safety

The bait stations we use are locked and positioned away from areas used by children and pets, in line with Belgian regulations on biocidal products.

Rats and mice in Brussels: why they are so common

An old sewer network, townhouses with cellars, countless restaurants and rubbish bags left out on the pavement: Brussels gives rodents food and shelter all year round. Rats come up through sewers and pipes, mice slip through the smallest gap into flats and buildings. We handle rat control in houses, flats, cellars, gardens, shops and restaurants across the Brussels Region.

Everything you need to know about rat control in Brussels

Rat or mouse: how to tell what you are dealing with

In Brussels, the most common rodent is the brown rat (Norway rat): large and stocky, it lives mainly in sewers, cellars, gardens and ground floors. The house mouse is much smaller and easily climbs to upper floors, false ceilings and kitchen cupboards. Droppings are the best clue: rat droppings are 1 to 2 cm long, mouse droppings look like grains of rice a few millimetres long. Identifying the species matters, because bait placement, the type of traps and the entry points to seal are not the same.

Where do rodents hide in a Brussels home?

Rats and mice look for warmth, darkness and nearby food. We most often find them in the cellars and crawl spaces of Brussels houses, behind skirting boards and kitchen units, in service ducts and building risers, under floors, in attics, and around compost bins, garden sheds and bin stores. In apartment buildings, an infestation often spreads from one flat to the next through pipe openings.

Rat control for businesses: restaurants, shops and property managers

Restaurants, snack bars, bakeries, food shops and warehouses are particularly exposed. In the food sector, pest control is part of the self-checking system monitored by the FASFC (AFSCA/FAVV): signs of rodents can lead to a warning or even closure. We set up a rat control plan suited to your business, with regular follow-up visits and discreet work, outside opening hours if needed. For property managers (syndics), we treat common areas such as cellars, bin stores and car parks in coordination with residents.

Landlord or tenant: who pays for rat control?

There is no single rule: it depends on the cause of the problem and on your lease. As a rule of thumb, if the infestation is due to a defect in the building (holes in walls, damaged pipes, unprotected drains) or existed before the tenant moved in, the landlord usually pays. If it results from how the property is used, it is often the tenant's responsibility. In a co-owned building, common areas are the property manager's responsibility. If in doubt, our diagnosis can often pinpoint where the infestation comes from.

What to do while you wait for us

Store food (including pet food) in airtight containers, keep bins closed and do not leave dirty dishes out overnight. Never touch droppings or dead rodents with bare hands: wear gloves and disinfect the area, as rodents can transmit diseases such as leptospirosis. Avoid scattering shop-bought rat poison: badly placed, it is dangerous for children and pets, and an established infestation needs a full treatment anyway.

How to keep rats and mice from coming back

Lasting rat control means closing off access: a mouse can squeeze through a gap of a few millimetres, a rat through a hole the size of a coin. We seal pipe openings, fit grilles on vents and point out the weak spots in your building. On your side, put rubbish bags out as late as possible before Bruxelles-Propreté collects them, keep compost closed, avoid feeding birds on the ground and do not leave food accessible in the garden or cellar.

Frequently asked questions

Depending on the scale of the infestation, expect one to three weeks between placing the bait and full elimination, followed by a check-up visit.

No: we use locked, secure bait stations that are inaccessible to children and pets.

The price depends on the area, the type of building (house, flat, cellar, shop) and how widespread the infestation is. After a free diagnosis we give you a fixed price before any work starts, follow-up visit included.

Yes, 7 days a week. For rats in a kitchen, bedroom or shop, same-day service is often possible across the 19 municipalities of Brussels.

No. Bait is placed in secure stations and traps are set in strategic spots: you can carry on living at home as normal, or keep your business open, throughout the treatment.

It may slow down a minor problem, but it does not deal with the source or the entry points. Badly placed, it puts children and pets at risk, and rodents quickly learn to avoid it. A professional identifies the species, the runways and the access points to get rid of the infestation for good.
