Tenancy

Who pays for pest control in a rental?

Whether the landlord or the tenant pays for pest control in a New Zealand rental, what the Residential Tenancies Act requires, and what decides borderline cases.

The short answer

In most cases the landlord pays. The Residential Tenancies Act 1986 requires landlords to provide and maintain premises in a reasonable state of repair, and pests entering through structural defects such as perished subfloor vents, unsealed penetrations or failed drainage is a maintenance matter. Tenants become responsible where the infestation results from how they are living in the property, for example food waste accumulation, or where they brought it in.

Who is responsible for pest control in a NZ rental?

In a NZ rental, the landlord must hand over the property free of pests and for the maintenance and repairs that keep them out, and the tenant is responsible for living in it in a way that does not invite them. Tenancy Services adds that where nobody can tell who caused an infestation the cost is often split, that the landlord should carry fumigation, and that the Tenancy Tribunal can order a tenant to pay where their lack of cleanliness caused it. That is also why our rodent treatment reports describe cause, not just the pest.

The relevant obligation sits in section 45 of the Residential Tenancies Act 1986, which requires a landlord to provide the premises in a reasonable state of cleanliness and to maintain them in a reasonable state of repair, having regard to the age and character of the premises.

Tenants have a corresponding obligation under section 40 to keep the premises reasonably clean and tidy and to notify the landlord of any damage or need for repair as soon as possible after they discover it. That notification duty matters more than most tenants realise, because a problem reported late is harder to attribute.

Neither section mentions pests specifically. The question is therefore always about causation: is the infestation the consequence of a repair issue, or of how the property is being occupied? A clause in the tenancy agreement cannot shift that onto the tenant either, because section 11 gives no effect to terms that conflict with the Act.

Where the line usually falls

Almost always the landlord: rats and mice entering through perished or missing subfloor vent mesh, gaps at service penetrations, a cracked gully trap or failed drainage, holes in cladding, an unclosed eave junction, or a subfloor that cannot be secured. Cockroaches coming up through drainage with a failed trap seal. Also a pest infestation demonstrably present at the start of the tenancy, or one bad enough to need fumigation.

Usually the tenant: an infestation clearly resulting from food waste accumulation, rubbish not being removed, or hoarding. Fleas introduced by the tenant's own untreated animal. Bed bugs brought in with the tenant's furniture, though this is frequently disputed and hard to prove either way. Because bed bugs arrive in luggage and second hand furniture, knowing where bed bugs come from and recording the state of the beds at the start of a tenancy is where that argument is usually won.

Genuinely arguable: a problem that appears mid-tenancy in a property with no obvious defect and no obvious housekeeping issue. This is where evidence decides it, and where most Tenancy Tribunal applications on this subject actually sit.

Borer is a separate case: borer in the framing, floors or subfloor comes with the age and timber of the building rather than anything a tenant did, so it falls under the landlord's repair duty in section 45 in almost every case, while borer in a tenant's own furniture is the tenant's. A dated record of what was found, and whether it was live, is what borer treatment is planned around.

Healthy Homes and ceiling insulation

There is a connection people miss. The Healthy Homes Standards require ceiling and underfloor insulation to be in reasonable condition, and insulation that is damp, damaged or contaminated does not meet the standard.

Rodents living in ceiling insulation contaminate it with urine and droppings. That is a compliance issue independent of who caused the rodents, and it is the landlord's obligation to remedy. If you are a tenant with rodents in the ceiling, this is worth raising alongside the pest question rather than after it. If you are not sure what is up there, start with what is in my ceiling.

What actually resolves these disputes

Evidence, and specifically dated evidence describing cause rather than just describing the pest. A treatment record that says "treated for rodents" settles nothing. One that says "subfloor vent mesh perished on the north and east elevations, active runs through both openings, droppings consistent with ship rat throughout the subfloor" settles a great deal.

That is why we provide a written report describing what was found, where it was found and what caused it as standard on every rental job rather than on request. It costs us nothing extra and it is usually the thing the customer actually needed.

For tenants: report in writing, keep the record, and photograph what you can. For landlords and property managers: treat between tenancies, keep the dated record on file, and you will rarely have this argument at all.

Questions

Rental pest control questions

Can my landlord make me pay for the pest control?

Only if the infestation is attributable to how you have been occupying the property. If it is getting in through a structural defect such as perished subfloor vents, unsealed penetrations or failed drainage, that is a repair obligation under section 45 and it sits with the landlord. Ask for the technician's written findings, because that document describes cause rather than just the pest.

What if my landlord will not act?

Put the request in writing and keep a copy, because the written trail matters. If it is not addressed you can issue a 14-day notice to remedy, and if that is not complied with you can apply to the Tenancy Tribunal. Tenancy Services can advise on the process. Do not withhold rent, as that creates a separate problem for you.

Does it matter that I did not report it straight away?

It can. Section 40 requires tenants to notify the landlord of the need for repair as soon as possible, and a long delay makes it harder to establish when the problem started and therefore what caused it. It does not automatically shift responsibility, but it weakens the position.

Who pays for fleas in a rental?

Usually the tenant where they keep an animal, since fleas arrive on the pet. Where the property was already infested at the start of the tenancy, which happens regularly when a previous tenant had animals, that is the landlord's. A dated inspection at the start of a tenancy resolves this argument before it starts, which is one of the reasons treating between tenancies is worth doing. A dated flea treatment between tenancies, with the record kept on file, settles the question for the next tenancy too.

Who pays for bed bugs in a rental?

Tenancy Services says the landlord must provide the property free of pests at the start of a tenancy. If bed bugs appear partway through with no clear cause, it says responsibility is unclear, and landlords and tenants often split the cost. Evidence decides it, so report them in writing straight away, learn how to check for bed bugs, and get a dated inspection.

Should a landlord treat for pests between tenancies?

The law does not say so in those words, but it comes close. Tenancy Services expects the property to be free of pests when a tenancy starts, and section 45 requires it to be reasonably clean. A dated property inspection or treatment between tenancies is the simplest way to show both, and it settles who pays if pests appear later.

What are the pest red flags for tenants at a viewing?

Look in the pantry and under the sink for droppings, behind the fridge and dishwasher for the egg cases and shed skins described in what a cockroach nest looks like, and in the meter box for chewed cable. Bait stations in every room, or a strong smell of fresh spray, suggest a problem being managed rather than solved. Leaks and mould matter too, because water feeds cockroaches and ants.
