Who Pays for Pest Control in a Rental Property in NSW? The Honest Answer

Highlights at a Glance

• Pest control for rental properties in NSW does not follow one fixed rule. It depends on who caused the problem and what was documented at the start of the tenancy.

• If pests were present before you moved in and the condition report confirms it, the landlord is responsible.

• If your habits during the tenancy attracted pests, that cost falls on you as the tenant.

• Flea treatment at the end of the lease is a legal requirement in NSW if you had pets on the property, regardless of whether fleas are visible.

• Termites are rarely a tenant issue. Annual inspections are the landlord's responsibility.

• It applies whether you are renting or managing a property in Wollongong, Shellharbour, Kiama, Nowra, or anywhere across the Illawarra.

This question lands in inboxes constantly. A tenant spots cockroaches two weeks into a new lease and wants to know if the landlord has to fix it. A landlord gets a pest treatment bill at the end of tenancy and wants to know if the bond covers it. A property manager is fielding calls from both sides and needs a straight answer.

But there is no single rule that covers every situation. What determines who pays is a combination of timing, cause, documentation, and what the tenancy agreement actually says. NSW law on pest control for rental properties gives a clear enough framework once you understand it. But applying it to a specific situation is where most of the confusion happens.

If you own, rent, or manage a property in the Illawarra, this post will give you the clearest picture available of where you stand. As a trusted pest control company, we want you to know every aspect of this case. So you can protect your property, bond, and most importantly, peace of mind. 

What the Law Actually Says About Pest Control in NSW Rentals

The starting point for any question about pest control for rental properties in NSW is the Residential Tenancies Act 2010. This legislation governs the rights and responsibilities of landlords and tenants across the state. It sets out the baseline obligations both parties carry throughout a tenancy.

Under the Act, a landlord must provide a rental property that is reasonably clean and fit to live in at the start of the tenancy. That obligation is not limited to the physical building structure. It extends to the property condition, including whether pests are present when a tenant moves in. A tenant, on the other hand, must keep the property reasonably clean during the tenancy and leave it in the same condition it was in at the start for fair wear and tear. Neither of those obligations uses the word pest directly. But both have clear and direct implications for who pays when a pest problem arises. 

What the Act does not do is hand all responsibility to one party in every situation. The question of who pays for pest control for rental properties almost always depends on a single determining factor: when did the problem start, and what caused it? Get those two things clear, and the answer usually follows.

When Tenants Are Responsible for Pest Control

There are situations where pest control for rental properties is clearly the tenant's responsibility. Understanding where that line sits means you can deal with the situation properly and protect your bond in the process.

You Created the Conditions That Attracted Pests

If the way you have been living in the property created an environment that drew pests in, the cost of dealing with them sits with you. Open food packaging left in pantries, rubbish not managed properly, dishes left out, organic waste sitting in bins without lids- these habits bring cockroaches and rodents into a home. 

If a pest inspection points to conditions like these as the cause of the infestation, a landlord has reasonable grounds to pursue the cost of treatment from your bond. Keep the property clean, manage food and waste properly, and this situation will not arise. Simple as that!

You Had Pets on the Property

This one has a specific legal basis in NSW, and there is no grey area around it. If you had a dog or cat living at the property during your tenancy, you are required to arrange a professional flea treatment at the end of the lease. You do not need to see fleas, your pet does not need to have shown any signs, and the property does not need to look dirty. The requirement stands either way. 

Flea eggs can lie dormant in carpet fibres for months and hatch when a new tenant moves in. Book the treatment after the property has been vacated and cleaned, and get a written certificate from a licensed technician to provide to your property manager.

You Are Leaving the Property in a Worse State

At the end of any tenancy, you need to leave the property in the same condition it was in when you moved in. If the property was documented as pest-free in the condition report at the start of the tenancy and there is now active pest activity, it is your responsibility to close the gap. 

This means arranging and paying for professional pest treatment before the final inspection and providing documentation to prove it was done. A receipt from a licensed pest controller is what your property manager needs. Without it, a bond deduction may be possible. If you have questions about what treatment is needed and what documentation is required, contact us, and we will walk you through it.

When Landlords Are Responsible for Pest Control

There are equally clear situations when the responsibility for pest control for rental properties belongs to the landlord. Tenants in these situations have every right to request treatment at no cost to themselves.

Pests Were Present at the Start of the Tenancy

If you moved into a property that already had a pest problem, the landlord failed to meet their obligation to provide a property that was reasonably clean and fit to live in. The condition report is your evidence. If it noted pest activity that was never addressed before you moved in, or if pests appeared within the first week or two in a way that clearly points to a pre-existing infestation, you have a legitimate basis to request treatment at the landlord's cost. 

Put the request in writing to the landlord or property manager, keep a copy of everything, and if the issue is not addressed within a reasonable time, you can take the matter to NCAT for a formal order. Do not attempt to deal with it yourself and absorb the cost without at least raising it in writing first.

Pests Are Entering Through Structural Defects

Not all pest problems during a tenancy are caused by tenant behaviour. If cockroaches, rodents, or other pests are consistently getting into the property through gaps in the building fabric, broken drainage, deteriorating seals around pipes, or other structural issues, that is a maintenance problem. The landlord is responsible for keeping the property structure in reasonable repair under the Residential Tenancies Act. 

If you have kept the property clean, managed food and rubbish properly, and pests are still appearing, the entry point is likely structural. Raise it in writing with your landlord or property manager, describe where the pests are appearing, and request both an inspection and repair of any defects found.

Termites Are Found on the Property

Termites are rarely a tenant issue. The conditions that lead to termite activity are property and maintenance factors that sit entirely within the landlord's control. Annual termite inspections by a licensed inspector are strongly recommended across NSW and are particularly important in the Illawarra, where coastal humidity and bush interface zones create higher termite pressure than most other parts of the state. 

If termites are discovered during a tenancy, the landlord is responsible for arranging and funding treatment. A tenant who notices signs of termite activity, like mud leads along walls, hollow-sounding timber, or discarded wings near window frames, should report it to the landlord in writing immediately. Do not disturb the area. Early reporting protects the property and protects you.

The End of Lease Pest Control Rules: What You Actually Need to Organise

End of lease is where most disputes over pest control for rental properties in NSW actually occur. Both landlords and tenants can find themselves caught out here, usually because the obligations were not clearly understood at the start of the tenancy.

The general rule is straightforward. You must leave the property in the condition it was in when you moved in, fair wear and tear aside. If the property was pest-free at the start and pests have appeared during your tenancy for reasons connected to how you have lived there, you need to arrange professional treatment before the final inspection. That means booking a licensed pest controller, not using a supermarket spray can, and obtaining a written certificate that your property manager will accept as evidence the job was done properly.

Timing matters here. Vacate first, get the carpets cleaned, then book the pest treatment. Just make sure the certificate is in your hands before the final inspection. Booking it the morning of the inspection is too late. Two to three days before key handover is the right window. Keep the receipt, keep the certificate, and send copies to your property manager rather than waiting to be asked.

For landlords, end of lease is also the right time to carry out a routine treatment if one has not been done recently. A property that is professionally treated between tenancies starts the next lease with a clean, documented baseline. That baseline is what protects you if a new tenant raises a pest complaint in the first few weeks of their tenancy. Without it, the argument about whether pests were pre-existing becomes much harder to win.
