Pest complaints are one of the most common issues property managers deal with across Sydney rental portfolios. Cockroaches in the kitchen. Mice behind the walls. Rats in the garage or garden shed. These are not fringe situations. They are everyday realities in a city with older housing stock, dense suburban living, and a climate that keeps pests active for much of the year.

What makes cockroach pest control particularly challenging in the rental property context is not the pest itself. It is the question of who is responsible, and what happens when the landlord, tenant, and property manager all have different views on the answer.

This guide is for Sydney property managers and landlords who want to understand their obligations, manage pest complaints efficiently, and put the right treatments in place to protect their properties and their tenant relationships.

Landlord vs. Tenant: Who Is Responsible for Pest Control in NSW?

This is the question at the heart of almost every pest complaint in the residential tenancy space, and the answer is not always straightforward. Responsibility depends on the nature of the infestation, when it arose, and what caused it.

Under the Residential Tenancies Act 2010 (NSW), landlords are required to provide and maintain a rental property in a reasonable state of cleanliness and fit for habitation. This means that if a property has a pre-existing pest problem, or if the infestation arises from the structure, condition, or location of the property, the landlord is responsible for treatment.

Common examples where landlord responsibility applies:

• Cockroach or rodent infestations present at the start of a tenancy
• Rats entering through structural gaps, broken drainage, or deteriorated building materials
• Recurring pest activity linked to neighbouring properties or the building's common areas, particularly relevant in strata
• Termite activity affecting the structure of the property

Tenants, on the other hand, are responsible for keeping the property reasonably clean and for not creating conditions that attract or harbour pests. If a tenant's housekeeping practices directly cause or worsen a pest infestation, the tenant may bear responsibility for the cost of treatment.

In practice, the line between these two scenarios is often disputed. A property manager's role is to assess the situation objectively, document findings thoroughly, and engage a licensed pest controller to provide a professional opinion on the likely cause. That professional assessment is often the deciding factor in any dispute. It also highlights why working with an experienced commercial pest control provider can be valuable for agencies managing multiple properties.

How to Manage Pest Complaints from Tenants

When a tenant raises a pest complaint, how you respond in the first 48 hours sets the tone for everything that follows. A slow or dismissive response risks escalating to a formal complaint to NSW Fair Trading, a rent reduction claim, or in serious cases, a Tribunal application.

A clear, documented process protects everyone involved.

Step 1 - Log the complaint immediately. Record the date, the nature of the complaint, the specific pest reported, and the location within the property. Even if the complaint comes in by phone, follow up in writing to create a paper trail.

Step 2 - Arrange an inspection promptly. Do not attempt to assess pest activity yourself unless you are trained to do so. Engage a licensed pest controller to inspect the property and provide a written report. This report should identify the pest type, the likely source or cause of activity, the extent of the infestation, and the recommended treatment.

Step 3 - Communicate clearly with the tenant. Let the tenant know an inspection has been booked, what access will be required, and what the process looks like from here. Tenants are more patient when they feel informed. Silence breeds frustration.

Step 4 - Action the treatment without unnecessary delay. Once you have a professional recommendation, move quickly to book the treatment. Under NSW tenancy law, landlords are expected to address maintenance issues, and pest infestations that affect habitability fall within that category, within a reasonable timeframe.

Step 5 - Follow up after treatment. Check in with the tenant after the treatment to confirm the pest activity has been resolved. If follow-up visits are required, which is common for cockroaches and rodents, ensure these are scheduled and communicated.

Treatment Options Safe for Occupied Rental Properties

One concern that frequently arises for property managers and tenants alike is whether pest treatments are safe to carry out while the property is occupied. The short answer is yes, provided the right treatment methods are selected and applied by a licensed professional.

Modern pest control for rental properties in Sydney has moved well beyond the broad chemical sprays of previous decades. Experienced pest controllers now use a range of targeted, low-disruption treatment options suited to occupied homes.

Cockroach control in occupied properties typically involves gel baiting, a highly effective treatment method where bait is placed in targeted locations (inside cupboards, under appliances, along wall junctions) that cockroaches are likely to encounter. Gel baiting requires no evacuation of the property, produces no fumes or residue in living areas, and is safe for households with children and pets when applied correctly. For more established infestations, a combination of gel bait and targeted residual treatment in roof voids or wall cavities may be recommended.

Rodent control in occupied properties generally involves a combination of baiting stations and physical exclusion work. Bait stations are placed in areas inaccessible to children and pets, such as inside roof voids, under floors, in garden sheds, or along fence lines, and checked at regular intervals. Physical exclusion (sealing entry points around pipes, vents, and structural gaps) is an important component of long-term rodent management and one that is often overlooked in reactive treatments.

For both cockroaches and rodents, a professional will always conduct a thorough inspection before recommending a treatment approach. The cause and extent of the infestation determines the method. This means a one-size-fits-all treatment is rarely the most effective or cost-efficient option.

Pre-Vacancy and End-of-Lease Pest Treatments

End-of-lease pest treatments are standard practice across the Sydney rental market, and for good reason. They protect the incoming tenant, reset the property to a known pest-free baseline, and reduce the likelihood of a dispute between outgoing tenants and landlords over bond deductions.

Many Sydney leases include a clause requiring tenants to arrange professional pest control prior to vacating, particularly for properties where pets have been kept, where the lease has run for multiple years, or where the property has a history of pest activity.

As a property manager, the end-of-lease period is also the right time to conduct a broader pest assessment, not just a treatment, to identify any conditions in the property that may lead to pest issues during the next tenancy. Entry points for rodents, gaps around plumbing, moisture-affected areas, and overgrown garden beds are all common contributors to recurring pest problems that a simple spray treatment will not address.

Pre-vacancy pest inspections from Safe Spray include a written report that documents current pest activity (or its absence), notes any structural or environmental conditions that present a pest risk, and recommends any preventative measures ahead of re-letting. This report can be retained on file as part of the property's maintenance history, providing valuable documentation if a pest issue is raised during a future tenancy.

For property managers handling high tenant turnover across a large portfolio, scheduling pre-vacancy inspections as a standard part of the end-of-lease process, rather than only when a problem is reported, is one of the most effective ways to stay ahead of pest issues and protect landlord clients from unexpected costs.

The Case for a Proactive Approach Across Your Portfolio

Cockroach and rodent complaints are among the most preventable pest issues in the rental property space. The conditions that attract these pests (food waste, moisture, structural entry points, landscaping against building walls) are identifiable and addressable well before an infestation takes hold.

For property managers in Sydney who are still relying on reactive call-outs to manage pest issues, the shift to a structured pest management plan across your portfolio is worth serious consideration. Regular scheduled inspections, consistent documentation, and a clear treatment protocol for each property type reduce both the frequency of pest complaints and the cost per incident over time.
