Pest complaints are among the most common issues strata managers deal with — and among the most difficult to resolve cleanly. Unlike a single-occupancy property, a strata building involves multiple owners, multiple tenants, shared common property, and overlapping responsibilities. Getting pest control right requires a clear process, a reliable provider, and a solid understanding of who is responsible for what.
This guide covers everything you need to handle complaints effectively and put a management plan in place that prevents them from recurring.
Why Strata Buildings Are High-Risk for Pest Infestations
Multi-unit buildings create conditions that pests find highly attractive:
- Shared walls and floor or ceiling voids allow pests to move freely between lots without obstruction
- Common areas — bin rooms, car parks, garden beds, and laundries — routinely provide food, water, and harborage
- With multiple occupants, one lot with a hygiene issue can seed an infestation that spreads throughout the building
- Older buildings tend to have more gaps in the building fabric, creating more entry points and harbouring opportunities
Rodents and cockroaches are particularly well-adapted to strata environments. German cockroaches travel through shared wall voids between adjacent lots; rats and mice access roof spaces that span the entire building footprint. Rat and mouse control and cockroach treatments in strata buildings require a whole-of-building approach, not a unit-by-unit response.
Who Is Responsible for Pest Control in a Strata Building
Responsibility depends on where the pest problem originates and where it is occurring.
Common property — lobbies, lifts, gardens, bin rooms, car parks, roof voids, and shared building services — is the responsibility of the owners corporation. The strata manager, acting on behalf of the owners corporation, is responsible for arranging and funding pest control in these areas.
Individual lots (apartments and units) are generally the responsibility of the individual lot owner. If a pest problem originates within a specific lot — for example, a cockroach infestation driven by hygiene conditions inside one unit — the owner of that lot is typically responsible for the cost of treatment.
The grey area arises when a problem moves between a lot and common property, or when the source is unclear. In these cases, the prudent approach is for the owners corporation to fund a building-wide inspection to establish the source, then assign costs based on the inspector’s findings.

How to Handle a Pest Complaint Step by Step
When a resident reports a pest problem, the way you manage it matters — both for resolving the issue and for maintaining a constructive relationship with owners and tenants.
Step 1: Take the complaint seriously and document it immediately. Record the type of pest reported, the location, the date received, and who made the report.
Step 2: Arrange an inspection by a licensed pest controller before committing to any treatment. Without knowing the extent and origin of the problem, treatments may be misapplied and ineffective.
Step 3: Determine responsibility based on the inspector’s findings. If the problem is in common areas or is building-wide in nature, the owners corporation funds treatment. If it is isolated to a specific lot, direct the owner to arrange treatment independently.
Step 4: Coordinate access for any building-wide or multi-lot treatment required. Written notice to affected lots is typically required under the relevant strata legislation in your state.
Step 5: Follow up. A single treatment is rarely the end of the matter in a strata setting. Arrange follow-up inspections, document outcomes, and report back to the owners and committee appropriately.
The Case for a Proactive Building-Wide Program
Reactive pest control — responding to complaints as they are reported — is expensive and inefficient in a strata context. A building-wide pest management program shifts the approach from reactive to preventive.
A proactive program typically involves scheduled inspections and treatments of all common areas on a regular basis — usually quarterly or bi-annually — with monitoring between visits. The benefits include:
- Pests are identified and treated before they generate resident complaints
- Documentation is always current and available for committee review or owner requests
- A consistent provider relationship means the pest controller understands your building’s specific risk profile and history
- Total annual cost is typically lower than managing multiple ad hoc callouts across the same period
For buildings with known recurring issues, older building stock, or locations near food businesses or established green spaces, a proactive program is particularly valuable and cost-effective.
What to Include in a Pest Management Brief
When engaging a pest control provider for a strata property, be specific about what you need:
- Scope of all common areas to be covered — bin rooms, car parks, and lift lobbies are often omitted and should be explicitly included
- Required service frequency and any scheduling constraints around building activity or quiet hours
- Documentation standards — service reports, pest activity logs, and records suitable for committee reporting
- Agreed response time for urgent callouts between scheduled service visits
- Whether individual lot inspections can be coordinated alongside common area work when needed
