Who is responsible for pest control: landlord or tenants?

May 15, 2025

Summary:

In Australia, landlords and tenants share responsibility for pest control, though legal obligations vary by circumstance and jurisdiction. Landlords must deliver and maintain a rental property in a pest-free, habitable condition, addressing infestations present before a tenancy or arising from structural issues. Tenants are expected to keep the premises clean, report outbreaks promptly, and manage minor pest issues caused by their activities. Understanding these roles and including clear lease clauses and open communication helps prevent disputes and protects both parties’ interests. For effective outcomes, many turn to professional Melbourne pest control providers.

Understanding Pest Control Responsibility

Determining who “owns” pest control can be confusing, as no single piece of legislation spells out exact duties for every scenario. In general:

  • Landlords must ensure the property is delivered and kept in a reasonable state of repair and free from existing infestations, often requiring trusted pest control services.
  • Tenants must maintain cleanliness and notify the landlord or property manager when pests are detected.

Tenant Responsibilities

Keeping the Property Clean

Tenants should store food safely, dispose of waste regularly, and clean up spills to deter pests.

Early Reporting

If a pest problem appears, especially one likely to predate their move-in, tenants must inform the landlord before engaging private exterminators to avoid non-reimbursement.

Handling Minor Infestations

Tenants may use store-bought traps or sprays for small outbreaks (e.g., ants, spiders), provided the infestation wasn’t due to structural issues.

Landlord Responsibilities

Pre-Tenancy Pest Control

Landlords must arrange professional treatment to eradicate pests before a new tenancy starts and ensure the property meets minimum housing standards.

Structural Issues and Termites

Infestations caused by building defects, such as cracks or poor sealing, and all termite (white ant) treatments remain the landlord’s obligation, regardless of timing. These cases are commonly addressed through commercial pest control providers for larger or multi-tenant buildings.

Lease Clauses

Including clear pest-control terms—especially where pets are involved—helps set expectations and can require tenants to fumigate for issues like fleas at lease end. 

Jurisdictional Variations

  • New South Wales: Under the Residential Tenancies Act 2010, landlords must deliver premises free of pests; tenants are liable if infestations result from their actions.
  • Queensland: The Residential Tenancies Authority mandates that rental properties meet minimum housing standards—including being vermin-free—unless pests are tenant-caused.
  • Other States: While similar principles apply, always check your local tenancy authority or add specific terms in your lease.

Preventing and Resolving Disputes

  1. Open Communication: Early, documented discussions help both parties agree on action steps and avoid tribunal intervention.
  2. Photographic Evidence: Tenants should photograph pest sightings and dates; landlords can use inspection reports to show pre-existing conditions.
  3. Tribunal Applications: If negotiation fails, either party can apply to the relevant state tribunal for a binding ruling on responsibility and costs.

Best Practices for Landlords and Tenants

  • Landlords: Schedule regular inspections, engage licensed pest controllers, and include pest-control clauses in leases.
  • Tenants: Maintain hygiene, report issues promptly, follow lease terms, and avoid self-treatment of significant infestations without consent, consulting domestic pest control Melbourneprofessionals where applicable.
