Pest Control: Landlord vs Tenant Responsibilities in South Australia

Understanding who's responsible for pest control in SA rental properties. A comprehensive guide to rights, obligations, and the Residential Tenancies Act.

Quick Answer: Who's Responsible?

Landlord Responsibilities:

  • • Provide pest-free property at tenancy start
  • • Fix pre-existing infestations
  • • Address structural issues causing pests
  • • Termite treatments and inspections

Tenant Responsibilities:

  • • Keep property clean and sanitary
  • • Report pest issues promptly
  • • Pay for pests caused by their actions
  • • General pest prevention measures

Understanding SA Residential Tenancies Act

Under the South Australian Residential Tenancies Act 1995, both landlords and tenants have specific obligations regarding pest control. The key principle is that landlords must provide a property that's fit for human habitation, which includes being reasonably free from pests.

Landlord Obligations in Detail

At Tenancy Commencement

Landlords MUST ensure the property is pest-free when a new tenancy begins. This includes:

  • • Conducting pest inspections before new tenants move in
  • • Treating any existing pest problems
  • • Providing documentation of recent pest treatments if requested
  • • Ensuring all entry points are properly sealed

During Tenancy - Landlord Pays When:

  • Pre-existing infestations: If pests were present before tenancy or appear within the first few weeks
  • Structural issues: Gaps in walls, broken screens, roof problems allowing pest entry
  • Natural occurrence: Seasonal pests like spiders, ants during typical activity periods
  • Termites: Always landlord responsibility as they affect property structure
  • Neighboring properties: When pests enter from adjoining units in complexes

Tenant Obligations in Detail

During Tenancy - Tenant Pays When:

  • Poor hygiene: Cockroaches or ants due to uncleaned spills, food debris
  • Pet-related pests: Fleas from tenant's pets
  • Failure to report: Small problem becomes infestation due to delayed reporting
  • Brought in pests: Bed bugs from second-hand furniture
  • Blocked maintenance: Refusing landlord access for preventive treatments

How to Handle Pest Issues as a Tenant

1

Report Immediately

Notify your landlord/agent in writing as soon as you notice pests. Include photos and dates.

2

Document Everything

Keep records of when pests appeared, your cleanliness standards, and all communications.

3

Allow Inspections

Cooperate with property inspections to determine the cause of infestation.

4

Know Your Rights

If landlord refuses to act on their obligations, contact SA Consumer & Business Services.

How to Handle Pest Issues as a Landlord

Best Practices for Landlords:

  • Pre-tenancy treatment: Always treat between tenancies as prevention
  • Quick response: Address reports within 48 hours to prevent escalation
  • Professional assessment: Use licensed pest controllers for inspections
  • Maintain property: Regular maintenance prevents pest entry points
  • Clear agreements: Include pest control clauses in lease agreements

Dispute Resolution Process

When Disputes Arise:

  1. Direct negotiation: Try to resolve with landlord/tenant directly
  2. Written agreement: Document any agreed solutions
  3. Mediation: Contact Consumer & Business Services for free mediation
  4. SACAT application: Apply to SA Civil & Administrative Tribunal if unresolved
  5. Tribunal hearing: Present evidence for determination

Preventive Measures for Both Parties

For Tenants:

  • • Keep property clean and tidy
  • • Store food in sealed containers
  • • Report leaks and moisture issues
  • • Don't leave pet food out
  • • Regular bin emptying
  • • Vacuum regularly

For Landlords:

  • • Annual pest inspections
  • • Check for and report cracks and entry points
  • • Maintain gutters and drainage
  • • Fix screens and doors
  • • Tree trimming from roof
  • • Professional prevention plans

Important Legal Considerations

Key Legal Points:

  • Warranty of Habitability: Landlords cannot waive their obligation to provide habitable premises
  • Rent Withholding: Tenants cannot withhold rent for pest issues - must follow dispute process
  • Urgent Repairs: Severe infestations may qualify as urgent repairs
  • Notice Requirements: Landlords must give proper notice before pest treatments
  • Cost Recovery: Either party can seek cost recovery through SACAT if wrongly charged
