You've just signed at the notary's, the boxes have barely been unpacked, and you wake up to discover puncture marks on your arms. Then brown stains on the mattress. Then marks along the baseboards. Bedbugs. In your brand-new apartment. The one you bought three weeks ago.

Things to remember

• We deal with the problem of bedbugs from the legal angle of hidden defects in real estate.

• The aim is to demonstrate, through our field expertise in Brussels, how an unreported infestation can justify the cancellation of a sale or a substantial price reduction.

The question quickly becomes: did the seller know? And above all, is there anything you can do? Cancel the sale, reduce the price, claim damages? The answer is yes, under certain conditions. Bedbug infestation can constitute a hidden defect in a property purchase, and the legal consequences for the seller can be severe.

At Punaises de lit Bruxelles, we regularly intervene in homes where the problem existed long before the arrival of the new owner. We see the signs, we know how to date them, and we can provide the technical elements that make the difference in a case. Here's what you need to know, concretely, if you're in this situation.

Understanding the legal warranty against hidden defects in real estate

Article 1641 of the French Civil Code is clear: the seller is liable for any hidden defects in the item sold which render it unfit for its intended use, or which impair that use to such an extent that the buyer would not have purchased it, or would have paid a lower price for it, had he been aware of them. This is the legal basis for hidden defects in real estate.

Four criteria must be met for a defect to be recognized as a latent defect. The defect must be prior to sale It already existed at the time of signing. It must be hidden A normally diligent buyer would not have been able to detect it during the visits. It must be serious It renders the property unfit for its normal use or significantly reduces its value. And it must not have been mentioned in the deed of sale.

This last point is crucial. If the seller has included a clause excluding the warranty for hidden defects in the compromis (which is often the case in transactions between private individuals), this clause only protects him if he is acting in good faith. A seller acting in bad faith, i.e. one who knew of the defect and knowingly concealed it, cannot hide behind this clause. It is deemed unwritten.

The legal warranty applies to any type of property: house, apartment, studio or investment property. And it covers a wide range of defects: structural problems, water infiltration, humidity, the presence of termites or merula, dangerous electrical installations. But what about pests? That's where it gets interesting.

Hidden defects in home purchases are not limited to walls and roofs. The defect may be biological, organic or living. Case law has already recognized insect infestations as characterized hidden defects, provided all four criteria are met. For bedbugs, the reasoning is the same, but proving the defect requires specific work.

Many new homeowners think that buying a property with a hidden defect is a foregone conclusion, that they just have to «live with it». But this is not true. The law protects you. You just need to know how to activate it, and above all, how to prove that the problem did not come from you.

Bedbug infestation: a latent defect?

A couple contacted us last year, two weeks after moving into an apartment in Ixelles. Bites from the very first night. At first they thought it was mosquitoes, but then they found adult bedbugs behind the headboard. Dozens of them. With moults, hatched eggs and traces of excrement embedded in the wood floor. This level of infestation doesn't set in in a fortnight. It takes months, sometimes over a year.

This is exactly the kind of finding that qualifies an infestation as a hidden defect in an apartment. When bedbugs are found after a house or apartment purchase, the central question is: Was the infestation already present before the sale?

As a pest expert in Brussels, we can assess the age of an infestation. There are many clues: the quantity of molts accumulated, the presence of nymphs at different stages of development, the extent of colonization (a single room or the whole dwelling), the degree to which droppings are encrusted in materials. A recent infestation lasting just a few days bears no resemblance whatsoever to an infestation that has been in place for six months. A professional eye makes all the difference.

For proof of infestation to be admissible, it must be thoroughly documented. Here's what we always recommend:

• Call in a pest control professional as soon as the pest is discovered, and request a detailed written report with photos, location of outbreaks and estimated age.

• Don't throw anything away until you've documented everything. Infested furniture, soiled baseboards, stained mattresses: these are all evidence.

• Contact a bailiff for an official report, if possible within a few days of discovery.

• Ask the neighbors: in a block of flats, they often know whether the previous occupant had pest problems.

Hidden defects in an apartment or house can be proven by a number of clues. No need for the seller to admit it. If the expert report shows that the infestation is old, that the dwelling was uninhabitable or severely deteriorated by the presence of bedbugs, and that nothing was mentioned in the deed of sale, you have a solid case.

A point we often forget: bed bugs make a dwelling unfit for habitation. You stop sleeping, develop skin reactions and sometimes anxiety disorders. This is no minor inconvenience. It's a serious defect, in the legal sense of the word. And that's exactly what the law requires to qualify as a hidden defect in a property purchase.

There remains the question of the seller's bad faith. If he lived in the property before selling it, it's almost impossible for him not to have noticed the infestation. Bedbugs bite. They leave visible traces. A seller who claims to have been unaware of the infestation, even though the bedroom walls are stained with excrement, frankly doesn't hold water. And if a professional treatment was carried out before the property was put up for sale (some sellers try a quick treatment to hide the problem), invoices can be found.

What are the remedies and deadlines for taking action against the seller in the event of a dispute?

You have the proof. The infestation predates the sale. The seller said nothing. Now what?

There are two main options. The first is the’redhibitory action In the event of an infestation, you can ask for the sale to be cancelled outright. The property is returned to the seller, and you recover the full price paid, plus any related costs (notary fees, moving expenses, costs of infestation treatment). This is the most radical option, but is justified when the infestation is massive and the property is truly uninhabitable.

The second option is the’estimating action You keep the property, but obtain a reduction in the sale price. The judge assesses the reduction in value caused by the hidden defect and sets the amount of the reimbursement. This option is often chosen when the buyer wants to stay in the property but feels, quite rightly, that he or she has paid too much for an infested property.

In both cases, you can request a compensation if the seller is found to have acted in bad faith. This covers treatment costs (which can run to several thousand euros for a severe infestation), replacement of contaminated furniture, temporary accommodation costs if you have had to leave your home, and even moral prejudice. Judges are increasingly recognizing the psychological impact of bedbugs.

The deadline for taking action is 2 years from discovery of the latent defect. Not from the moment of sale: from the moment you discover the problem. This is an important distinction. If you buy in January and discover the infestation in March, your 2-year period for latent defects runs from March. But don't delay. The longer you wait, the more difficult it will be to prove that the infestation predates your purchase.

Here are the practical steps to follow:

1. Have the infestation recorded by a professional and a bailiff, as soon as possible after discovery.

2. Send a formal notice to the seller by registered mail, describing the problem and requesting an amicable resolution.

3. If the seller does not respond or refuses, take your case to court. A lawyer specialized in real estate law will guide you through the procedure.

4. The judge will probably order a legal expert opinion to confirm the age of the infestation and assess the damage.

An important clarification for those who buy «as is»: even an "as is" purchase does not deprive you of the guarantee against hidden defects. "As is" means that you accept the visible condition of the item. Not hidden defects. The nuance is fundamental, and many sellers (or their agents) try to make you believe otherwise.

For apartment purchases with hidden defects, as for houses, the procedure is identical. In the case of apartment buildings, you need to determine whether the infestation originated in the apartment being sold or in the common areas. Here again, a pest expert in Brussels can make the distinction by analyzing outbreaks and propagation routes.

One last tip: keep all the bills. Treatment, cleaning, bedding replacement, medical consultations, hotel nights. Every euro spent on this infestation is potentially recoverable if the seller is found responsible.

Conclusion

Discovering bedbugs after buying a property is a nightmare. But it's a nightmare with legal solutions. If the infestation existed before the sale, and the seller didn't inform you of it, you're within your rights to cancel the property sale, reduce the price, and claim compensation for costs and damages.

Speed is the key. Report the infestation, document it, take action. And surround yourself with the right professionals: a pest control expert capable of dating the infestation, a bailiff for the report, a lawyer for the proceedings.
