In Brussels, this question comes up again and again. And the answers you find online are often vague, based on French or Walloon legislation, and not always adapted to the Brussels-Capital Region. The problem is that the Brussels Housing Code has its own rules. And they're not identical to what you read on generalist forums. We're going to untangle all that, with texts to back them up, and ready-to-use letter templates if your landlord turns a deaf ear.

Whether you're a tenant bitten every night or a landlord facing a complaint, this article gives you the precise legal keys to finding out who should foot the bill for bedbug extermination in Brussels.

The Brussels Housing Code: Who is legally responsible?

Let's start with the text itself. The Brussels Housing Code imposes a clear obligation on landlords: to provide accommodation that complies with safety, health and equipment requirements. Article 4 sets the framework. A dwelling infested with bedbugs does not meet these criteria. Point.

Housing legislation in Brussels doesn't mention bedbugs by name, and that's often where confusion arises. However, the implementing decrees detail the standards of sanitation, and the presence of pests making a dwelling unfit for habitation falls directly under this definition. A dwelling with an active infestation is not sanitary. Landlords are therefore obliged to guarantee the sanitary condition of the property they rent out, bedbugs included.

So does that mean the owner always pays? Not exactly. When it comes to bedbugs, the landlord's obligation is to deliver a dwelling in good condition, and to make the necessary repairs to keep it that way. If the infestation was present before the tenant moved in, or if it stems from a defect in the building (cracks in the walls, pipes shared with an infested building), the burden clearly falls on the landlord.

The tenant, on the other hand, has an obligation to maintain the property and report any problems promptly. This is the famous «bon père de famille» principle of Belgian civil law. If a tenant notices bedbugs and waits three months before notifying his landlord, he runs the risk of being accused of aggravating the situation. The Brussels Housing Code protects tenants, but only if they also play their part.

A point often overlooked: in an apartment building, if the infestation affects several units, it's almost always a structural problem or one linked to the common areas. Landlords can't just say «it's your problem». It's the landlord's primary responsibility to ensure the healthiness of housing in Brussels. Bedbugs don't respect leases; they pass from one apartment to another via electrical outlets, baseboards and service ducts. When the infestation is collective, the treatment must also be collective, and it's up to the landlord (or the syndic for common areas) to coordinate and finance the intervention.

Remember this simple rule: the landlord must deliver a healthy dwelling and keep it in good condition. The tenant must maintain it properly and report problems promptly. What happens next depends on who «caused» the infestation, and that's the subject of the next section.

Proof of infestation: Determining the cost of treatment

90% of bedbug disputes in Brussels revolve around a single question: who introduced the bugs into the dwelling? And that's where it gets tricky, because proving the origin of a bedbug infestation isn't easy.

The first thing to think about is the inventory of fixtures. In Brussels, an inventory of fixtures is mandatory. If this document shows no traces of bedbugs (no stains on mattresses, no droppings, no molting), the landlord can claim that the property was clean when the keys were handed over. But beware: bedbugs are champions of discretion. An incipient infestation can go completely unnoticed during a standard inventory of fixtures. A pest expert is not part of the standard process, and a few individuals hidden in a skirting board cannot be seen by the naked eye.

That's why the state of play in Brussels, however well done, is not absolute proof. It's a clue, not a verdict. If you're a tenant and bedbugs appear two weeks after you've moved in, chances are the infestation was already there. Bedbugs don't reproduce so quickly: a visible problem in the first few weeks points to a previous presence.

The tenant can be held liable for bedbugs in one specific case: if the insects were introduced via second-hand furniture, luggage after a trip, or a salvaged item. The problem is that the landlord has to prove this origin. And this proof is extremely difficult to provide. Just saying «the tenant brought them in» isn't enough. Concrete evidence is required.

Here are the criteria that weigh in the balance when determining who should pay for bed bug treatment:

• Time to appear after moving in: Less than two months, the infestation was probably pre-existing. Six months or more is less obvious.

• History of the building : Have other tenants reported bedbugs? If so, the problem is structural.

• Professional report : A qualified exterminator can estimate the age of an infestation by analyzing the stage of development of the colonies. It's worth its weight in gold in the event of a dispute.

• Housing condition : Unsealed cracks, loose baseboards and poorly maintained false ceilings all contribute to the spread of mould. This is a breach of the lessor's maintenance obligation.

Here's a practical tip: as soon as you spot the slightest sign, take time-stamped photos. Film insects, tracks and bites. Send an email to your landlord (not a text message, email or registered letter) to create a dated paper trail. This documentation will be crucial if the case ends up before the justice of the peace.

Bedbugs are not a rental expense in the traditional sense. It's not like changing a light bulb or unclogging a sink. Bedbug extermination in Belgium is a specialized and often costly operation (expect to pay between 400 and 800 euros per treatment, sometimes more if several treatments are required). It's not routine maintenance, it's sanitation.

Owner who refuses to act : Remedies and model formal notices

Your landlord has received your report and isn't budging. No response, or worse, a «you're on your own». Unfortunately, this happens all the time. Here's exactly what you can do, step by step.

Step 1: Formal notice. It's the first step in any procedure. A formal notice for bedbugs is a registered letter with acknowledgement of receipt reminding the landlord of his legal obligations and setting a deadline for action. Without this letter, a judge will consider that you haven't given the landlord a chance to react.

Here is a sample letter to the landlord that you can adapt:

[Your name and address]

[Owner's name and address]

[Date]

Subject: Formal notice, bedbug infestation

Dear Sir/Madam,

I hereby inform you that the apartment located at [full address], which I occupy under the terms of the lease signed on [date], is currently infested with bedbugs. I noticed the infestation on [date noticed] and informed you by [email/courier] on [date first reported].

In accordance with the Brussels Housing Code and articles 1719 and 1720 of the Civil Code, you are obliged to provide me with a dwelling in a healthy condition and to make the necessary repairs to maintain this condition. An infestation of bedbugs constitutes a breach of this obligation.

I hereby give you formal notice to carry out, within 15 days of receipt of this letter, a complete professional treatment of the infestation by an approved specialist company.

Should you fail to respond within this period, I shall be obliged to refer the matter to the Regional Housing Inspectorate and/or the competent Justice of the Peace, with a view to having the dwelling brought up to standard and the costs incurred reimbursed.

Yours sincerely.

[Signature]

Step 2: The Regional Housing Inspectorate (DIRL). If the landlord doesn't react after your formal notice, you can report the insalubrity problem in Brussels directly to this regional service. An inspector can then visit the property, observe the infestation and officially put the landlord on notice. This procedure is free of charge, and may result in a ban on renting out the property if it is deemed unfit for habitation.

Stage 3: Justice of the Peace. This is the competent court for rental disputes in Brussels. You can file a claim without a lawyer (although it helps to have one). The judge can order the landlord to carry out the treatment, authorize you to carry it out yourself and deduct the cost from your rent, or award damages for the harm suffered (disturbance of enjoyment, medical expenses related to injections, replacement of bedding).

A point that many tenants are unaware of: you have the right to have the treatment carried out yourself in an emergency, and then claim reimbursement from the landlord. Article 1144 of the Belgian Civil Code allows this. Keep all invoices, estimates and written exchanges. A well-documented case is a successful case.

Another possible recourse is to contact your local mediation service. Several Brussels communes (Ixelles, Saint-Gilles, Schaerbeek, among others) offer a free mediation service between tenants and landlords. This can help break the deadlock without going to court.

And don't forget your tenants' associations. The Syndicat des Locataires (tenants' union), RBDH (Rassemblement Bruxellois pour le Droit à l'Habitat) and front-line legal aid services can help you with your case, often free of charge.

Conclusion

The question of whether the landlord or tenant should pay for a bedbug infestation in Brussels has a clear-cut answer in most cases: it's up to the landlord to ensure the sanitation of his property. The Brussels Housing Code leaves little room for ambiguity on this point.

The tenant only assumes responsibility if he or she is clearly the cause of the infestation, and even then, it's up to the landlord to prove it. When in doubt, the law protects the occupant.

If you find yourself in this situation, don't just sit back and wait. Document everything from day one, send a formal notice if necessary, and don't hesitate to call in a professional bedbug treatment company in Brussels to obtain a report as proof. At Punaisesdelitbruxelles, we know these situations inside out, and we can help you with both the technical aspects and the documentation you need to assert your rights.
