Cockroaches in the utility shaft, bedbugs migrating from one apartment to another, rats in the garbage room: when an infestation affects a building, it's rarely an isolated problem. And yet, the majority of residents struggle to get their condominium manager to react quickly to pests. E-mails ignored, responsibility shifted, estimates never validated. The pattern repeats itself.

What many condominium owners and tenants don't know is that they have a solid legal arsenal at their disposal to compel their building manager to take action. You don't need to be a lawyer: you just need to know the right levers, the right deadlines and the right wording. That's exactly what we're going to detail here, step by step, based on current law and what we're seeing in the field in 2026.

The aim is not to drown you in legal jargon. It's to give you a clear roadmap for transforming a report into a real intervention, with a qualified service provider, within a reasonable timeframe, and without costing you what it shouldn't cost you.

The legal framework: the building manager's obligations with regard to pests

A building manager has no choice. It's not a question of goodwill or available budget: the syndic's contract is to maintain the building in good sanitary condition. The syndic is responsible for the conservation of the building, its administration and the management of the common areas. When pests proliferate in service stacks, cellars, garbage chutes or common areas, it's his problem. Directly.

This safety obligation is not limited to major structural damage. It covers everything that affects the health of the building. A study published by the Anses (Agence nationale de sécurité sanitaire) reminds us that rodents are vectors of leptospirosis and salmonellosis, and that bedbugs in condominiums cause documented psychological problems: insomnia, anxiety, social isolation. We're talking about public health, not just a nuisance.

What does this mean in practice? It means that the building manager can't just say «We'll see at the next AGM». When an infestation affects the common areas, he is obliged to intervene without waiting for a vote at the general meeting, as a matter of urgency. The courts are clear on this point: a property manager who delays in dealing with a pest infestation in the building is committing a management error. And mismanagement is one of the serious faults that can justify the dismissal of a condominium manager.

For tenants, the leverage is different but just as effective. The lessor (your landlord) owes you decent, pest-free accommodation, in accordance with the right to housing (art. of the Brussels Housing Code). If the infestation comes from the common areas, the landlord must contact the syndic. If he fails to do so, you can contact the condominium council, or even the Justice of the Peace. The owner remains your contact, but it's the syndic who must initiate eradication in common areas.

A point that is often overlooked: compulsory insect control cannot be decreed on a case-by-case basis. When a building is affected by bedbugs, treating a single apartment is useless if the adjoining units are not inspected. In France, INRS and the national bedbug control protocol recommend coordinated treatment of all affected lots. This is also the case in Belgium. The building manager is responsible for coordinating this global intervention, including access to private areas with the occupants' consent.

The reporting procedure: how to force intervention

Sending an e-mail to the property manager vaguely describing «bugs in the corridor» isn't enough. If you want to get things moving, you need to build a solid case from the outset. Here's how to do it, in order.

First step: document the infestation. Take sharp, time-stamped photos. Film if possible. Note the dates and precise locations (stairwell B, 3rd floor, kitchen-side service shaft, garbage room). If you see rodent droppings, tracks or insect molts, photograph everything. This visual infestation report is your first piece of evidence. To go further, you can call in a diagnostician or pest control professional to draw up a technical report. This costs between 80 and 200 euros, depending on the region, but it carries a lot of weight.

The second step is to notify the building manager in writing. Forget the phone call. Send a registered letter with acknowledgement of receipt. This is the only format that has indisputable legal value and triggers legal deadlines. In this letter, describe the situation in detail, enclosing photos and, if applicable, the diagnostician's report. Cite the health, safety and maintenance obligations set out in the building owner's contract. Explicitly request the intervention of a certified professional to eradicate pests in the building, with a deadline for response (15 days is reasonable).

An effective model letter contains three elements: a factual description of the problem, a reminder of the syndic's legal obligation, and a formal demand to act within a specified timeframe. There's no need to threaten in the first letter, but be firm and precise. Vagueness is what allows the syndic to stall.

Third step: mobilize the condominium council. It's a powerful gas pedal. The condominium council is the supervisory body of the managing agent, elected by the condominium owners. If you alert its president (or members) at the same time as your letter, the pressure is stepped up a notch. The syndic knows that an informed condominium council will follow up the matter, ask questions at the AGM, and potentially vote on a resolution of no-confidence. In fact, when the syndic's council supports a co-owner's request, the syndic reacts two or three times faster. It's a fact of life.

Fourth step: reminder and formal notice. If after 15 days nothing moves, send a second registered letter. This time, describe it explicitly as a formal notice. Point out that the syndic's inaction engages his civil liability, and that you reserve the right to refer the matter to the Justice of the Peace. Mention the Civil Code and his contractual liability. At this stage, most trustees unblock the case, because they know that jurisprudence is not in their favor.

For tenants, the procedure is slightly different. Your first letter should be addressed to your landlord, with a copy to the building manager. If your landlord doesn't respond within a month, you can take the matter directly to the local health and safety department, which has the power to issue a formal notice to the syndic by municipal decree. This is a lever that few tenants are aware of, and it's frighteningly effective.

A detail that makes all the difference: keep a copy of every exchange, every acknowledgement of receipt, every dated photo. If the case ends up before a judge, it's this documented chronology that will make the difference between a vague claim and an unstoppable case.

Expenses and disputes: who pays and what to do if things get stuck?

It's THE question that crystallizes tensions. Who pays for rodent control in condominiums? Pest control in common areas? Coordinated bedbug treatment? The answer depends on the origin and location of the infestation.

Case n°1: the infestation affects common areas. Cellars, service ducts, garbage chutes, halls, garbage rooms. Charges are allocated according to the classic rule of general common charges, in proportion to the tantièmes of each lot. The expense is absorbed by the condominium's current budget. The managing agent may incur this expense as an emergency without a prior vote at the General Meeting, provided he informs the co-owners as soon as possible and has the expense ratified at the next General Meeting.

Case n°2: the infestation starts in a private lot and spreads. Let's imagine that an apartment is the focus of a bedbug infestation that migrates to neighboring dwellings via ducts and baseboards. Treatment of the source unit is the responsibility of the occupant (or landlord if the occupant is a tenant). Treatment of common areas and overall coordination remain the responsibility of the condominium. In practice, the syndic mandates a single service provider to handle all the work, and the invoice is split between common charges and individual charges. If the co-owner responsible refuses to treat his lot, the syndic can issue a formal notice and, as a last resort, apply to the court for an injunction to do so.

Case n°3: the managing agent refuses to act. You've sent your registered letters, mobilized the union council, and nothing. The situation is completely deadlocked. What can you do if you have a problem with your condominium manager? You have several options, in ascending order of pressure:

1. Contact the municipal health and hygiene service (SCHS). Free, fast. An inspector can note the insalubrity and issue a decree obliging the building owner to take action, subject to a fine. This is often the trigger.

2. Take legal action through the Justice of the Peace. You can ask the judge to order the building manager to carry out the work, possibly subject to a fine (a sum for each day's delay). The summary procedure allows you to obtain a decision within a few weeks when the health emergency is serious.

3. Ask for the trustee's dismissal. If inaction is systematic, this constitutes serious misconduct and justifies dismissal at an Extraordinary General Meeting. The resolution must be put on the agenda and passed by an absolute majority.

On the question of expenses advanced by a co-owner: if you have had to pay for an emergency intervention out of your own pocket because the managing agent failed to react, you can claim reimbursement from the syndicate of co-owners. The French Supreme Court (Civ. 3e, January 11, 2012, no. 10-27.397) has confirmed that a co-owner who incurs conservatory expenses due to the failure of the syndicate to act can obtain reimbursement, provided that he can prove the emergency and that a prior formal notice has gone unheeded. Hence the importance of documenting everything in writing.

For tenants, the situation is simpler on paper: your landlord must bear the cost of treatment if the infestation is not your fault. If the landlord refuses, you can deposit the rent with Caisse des Dépôts after the judge's ruling, or refer the matter to the conciliation commission. Financial pressure usually gets things moving pretty quickly.

A final point that often comes up: the actual cost of an intervention. Depending on the size of the building, a pest control treatment in a condominium costs between 150 and 500 euros per visit. A complete bedbug treatment (thermal + chemical) for a building with 20 lots costs between 3,000 and 8,000 euros. On a per unit basis, that's a few dozen euros per co-owner. Compare that to the cost of an infestation that lasts six months because nobody wants to pay: building deterioration, property depreciation, medical expenses, tenant turnover. Inaction always costs more than intervention.

Conclusion

Asking your building manager to eradicate pests is not asking for a service. It's exercising a right, backed up by clear legislation and consistent case law. Document your request, send it by registered mail, mobilize the union council, and don't hesitate to refer the matter to the health authorities if the blockage persists.
