Pest Control

A Battle of Responsibilities

The presence of ongedierte (pests) in a rental property can range from a minor annoyance to a serious health hazard. This category is broad, covering everything from silverfish (zilvervisjes) and ants (mieren) to more severe infestations of mice (muizen), rats (ratten), cockroaches (kakkerlakken), and the dreaded bedbugs (bedwantsen). Unlike a clear-cut issue like a broken heater, the responsibility for pest control (ongediertebestrijding) is one of the most significant grey areas in Dutch rental law. The core of the dispute almost always boils down to one question: was the infestation caused by a structural defect in the property, or by the tenant's lifestyle? The law offers principles rather than absolute rules, creating a fertile ground for disputes where landlords and tenants point fingers, leaving the pests to thrive in the meantime.

This ambiguity means tenants cannot assume the landlord will simply call and pay for an exterminator. A landlord's immediate reaction is often to question the tenant's hygiene or habits. Did you leave food out? Is the apartment cluttered? Do you take out the trash regularly? While these questions can be valid, they can also serve as a smokescreen to deflect the landlord's own responsibility. Pests, particularly rodents, are adept at exploiting structural weaknesses—cracks in the foundation, gaps around pipes, or holes in the walls of adjacent properties. Proving that the infestation is a consequence of the building's poor condition, rather than your own doing, is the tenant's primary challenge.

The Landlord's Burden: Structural Defects

The landlord's responsibility for pest control is directly tied to their duty to maintain the property and fix defects (gebreken). If it can be proven that the pests are entering the home because of a structural issue, the landlord is responsible for both the cost of extermination and the cost of repairing the entry point. For example, if there is a colony of mice living in the wall cavity of an apartment complex and entering through holes around plumbing, it is unequivocally the landlord's problem. Similarly, if an apartment is infested with pests before the tenant moves in, the landlord is in breach of their obligation to deliver a property in good condition. The costs to remedy this are entirely for the landlord.

However, proving this is not always straightforward. A savvy tenant should immediately document any potential entry points with photographs and formally notify the landlord in writing. The argument is strongest when the issue is clearly beyond the tenant's control, such as woodworm (houtworm) in the building's structural beams or a rat problem affecting an entire building block. In these cases, it's not an isolated issue in one apartment but a building-wide defect. Landlords who refuse to act in these situations are taking a significant legal and financial risk, as tenants can proceed to the Huurcommissie (Rental Tribunal) to force repairs and demand a rent reduction.

The Tenant's Role: Minor Pests and 'Good Tenancy'

On the other side of the coin is the principle of kleine herstellingen (minor repairs), which are the tenant's responsibility. The law expects tenants to handle minor, non-structural issues themselves. This often includes dealing with isolated pests that are not the result of a building flaw. For example, a trail of ants leading to a sugar bowl on the counter is the tenant's problem to solve. Likewise, a few spiders or flies are considered a normal part of inhabiting a dwelling. This falls under the broad expectation that a tenant acts as a goed huurder (good tenant), which includes maintaining a reasonable level of cleanliness.

The real conflict arises when the infestation is more severe. Take bedbugs (bedwantsen), for instance. These are notoriously difficult to eradicate and even harder to trace. Did they arrive in the tenant's second-hand mattress, or were they dormant in the apartment's skirting boards from a previous tenancy? There is often no clear answer, leading to protracted disputes. In these cases, the tenant's best approach is to act in good faith, inform the landlord immediately, and propose a shared solution. If the landlord refuses to cooperate on a serious infestation with an unclear origin, seeking advice from the Juridisch Loket (free legal aid service) or the Huurcommissie is the next logical step. The tenant should never simply withhold rent; they must follow the official procedures to build a strong case.
