Tenant vs Landlord Pest Control in SA: Who Pays?

Under the Residential Tenancies Act 1995 (SA) and SA Government guidance, the landlord is usually responsible for pests that are present at the start of a tenancy and for termites, and for sealing up entry points such as gaps that let rodents or possums in. The tenant is usually responsible for getting rid of pests that turn up during the tenancy, and for keeping the premises reasonably clean. Your tenancy agreement can add reasonable extra conditions — such as a flea treatment at the end of the lease where pets were kept. This article is general information, not legal advice: if you’re unsure, check with Consumer and Business Services (CBS).

That is the short version. The detail below explains where the line usually falls in practice, what common tenancy agreement clauses mean, why termites sit with the landlord, and what to do when the other party isn’t doing their bit.

What the SA rules say

The Residential Tenancies Act 1995 is the main legal framework for residential renting in South Australia. The SA Government’s guidance on repairs and maintenance in private rentals sets out who is usually responsible for pests:

• At the start of a tenancy — landlords are usually responsible for getting rid of ants, bees and wasps, cockroaches, fleas, spiders, mice and rats.
• During the tenancy — tenants are usually responsible for getting rid of pests, and landlords need to seal off any entry points. (Bees and wasps in a wall cavity sit with the landlord.)
• Termites, possums and birds — the landlord’s responsibility (for possums and birds, removal and sealing entry points).

The principles behind that guidance:

The landlord’s “fit to live in” obligation

The Act requires the landlord to provide the premises in a reasonable state of cleanliness at the start of the tenancy and to keep them in a reasonable state of repair, having regard to their age, character and prospective life. Pest problems that come with the property — termites in the framing, rodents getting in through structural defects, an infestation already there at move-in — generally fall on the landlord’s side.

As a general rule, a tenancy agreement can’t take away protections the Act gives tenants, so a clause making the tenant responsible for “all pest control” may not be enforceable to the extent it conflicts with the Act. If in doubt, ask CBS.

The tenant’s “reasonable cleanliness” obligation

The tenant must keep the premises reasonably clean during the tenancy and must not intentionally or negligently damage them. In practice that covers conditions within the tenant’s control — food storage, waste management, pet hygiene, ventilation — that contribute to pest pressure.

The “fair wear and tear” line

Fair wear and tear isn’t the tenant’s liability. Minor, normal pest activity (a small ant trail in summer, a single cockroach in a building with shared walls) is different from a persistent infestation caused by how the premises are kept (food residue left for months, pet waste accumulating).

The tenancy agreement’s role

The standard residential tenancy agreement form (issued by Consumer and Business Services SA) and most agency-drafted variations add detail on top of the Act — pet conditions, end-of-lease cleaning expectations, professional pest control clauses. The agreement cannot reduce the tenant’s protections under the Act. Where the agreement adds specific tenant obligations (e.g. professional flea treatment if pets have been kept), those obligations are enforceable provided they are reasonable and the tenant agreed to them at signing.

Where the line falls — examples

The Act’s principles applied to common scenarios:

Cockroach infestation already present at move-in — landlord

A cockroach infestation visible on the move-in inspection (or reported by the tenant within a reasonable period after move-in, before the tenant’s occupation could plausibly have caused it) sits inside the landlord’s “fit to live in” obligation. The landlord must arrange treatment at their cost. The tenant should note the infestation on the ingoing inspection report and notify the landlord/agent in writing as soon as possible.

Cockroach infestation from poor food storage during tenancy — tenant

A cockroach population that develops six months into a tenancy and is traceable to the tenant’s food storage practices (uncovered food residue, cluttered cupboards, garbage retention) sits inside the tenant’s “reasonable cleanliness” obligation. The tenant pays for treatment.

The line is not always crisp. German cockroach infestations in apartment buildings (multi-tenancy, shared walls, common cavities) often originate in another unit and migrate; the responsibility analysis runs through the building’s body corporate or the landlord’s structural maintenance obligation. The full mechanism is covered in the Pest Fox German cockroach treatment article.

Rodent activity from a structural cavity entry point — landlord

Rats entering through a gap in the eaves, a broken weep-hole, a damaged subfloor vent, or a hole in an exterior wall sit inside the landlord’s structural maintenance obligation. The structural defect is what enables the activity; the landlord owns the structural defect. The treatment and the structural repair both sit on the landlord’s side.

Rodent activity from open garbage — tenant

Rats attracted by tenant garbage left in the open, food waste in the yard, or pet food bowls left out overnight sit inside the tenant’s reasonable cleanliness obligation. Treatment cost is the tenant’s.

Termites — landlord

Termites are a structural pest. They affect the building, not the tenancy. The landlord owns the structural risk and the AS 3660.2-2017 inspection cycle that maintains it — covered in detail in the Pest Fox guide to termite inspections in Adelaide.

A tenant who finds termite signs (mud tubes, frass, hollow timber, alate emergence) during tenancy should report immediately in writing to the landlord/agent. The landlord is responsible for inspection, treatment and any structural repair. The tenant shouldn’t attempt termite treatment themselves — termite work should be done by a licensed pest controller, guided by AS 3660.2-2017.

Bed bugs from an imported mattress — tenant

A bed-bug introduction traceable to tenant-supplied furniture (typically a second-hand mattress, a backpacker hostel transmission, or a return from infested travel accommodation) sits inside the tenant’s responsibility. Treatment cost is the tenant’s.

The cost picture and treatment options are covered in the Pest Fox bed bug treatment cost in Adelaide article.

Pre-existing bed bugs at move-in — landlord

A bed-bug infestation already established at move-in (visible on the inspection report, reported within a reasonable period after move-in) sits inside the landlord’s “fit to live in” obligation. The landlord arranges and pays for treatment.

Standard tenancy agreement clauses and what they actually mean

Three clauses appear in most Adelaide residential tenancy agreements that touch pest control:

“Tenant must professionally pest-control at end of lease”

A common clause in many agreements, particularly where pets are allowed. Generally, a reasonable clause like this can be enforced. What’s generally reasonable:

• A general pest treatment (kitchen, bathroom, perimeter) at end of lease
• A flea treatment if pets have been kept during the tenancy
• A written certificate as proof of treatment

What’s generally not reasonable:

• A demand for treatment of specific pest categories the tenant cannot have caused (e.g. termites, structural rodents)
• A demand for repeated treatments where the first did not eliminate a pre-existing infestation
• A demand for treatment beyond what would constitute reasonable cleanliness

”Pet flea treatment clause”

Standard where pets have been kept. The expectation is usually a full-property flea treatment — interior, exterior, carpets — by a licensed pest controller, with a written certificate dated after the treatment. Where the agreement includes it, the cost is usually the tenant’s. Cost picture in the Pest Fox end-of-lease pest control article.

”Premises returned in same condition” clause

The general clause that runs throughout most agreements. It is constrained by the “fair wear and tear” exception in the Act. Pest activity that constitutes fair wear and tear is not a tenant cost; pest activity caused by the tenant’s behaviour is.

A clause that tries to make the tenant responsible for all pest issues, including termites, may not be enforceable to the extent it conflicts with the Act — check with CBS if you’re unsure.

Pet-related pest control

Where the tenancy agreement permits pets and pets have been kept, the end-of-lease pet-flea-treatment expectation is the routine outcome. The detail:

• Full-property flea treatment — interior + exterior + carpets + soft furnishings remaining
• Licensed operator — a business with an SA Health Pest Controller’s licence and licensed technicians (how to check is covered in the Pest Fox SA Health pest controller’s licence guide)
• Written certificate — dated after the treatment, naming the products used and the technician’s licence details
• Cost — typically $180–$350 for an end-of-lease treatment on a standard residential property in Adelaide

Where pets have caused other documented damage (urine staining of carpets, structural damage), those are separate claims under the bond — flea treatment is the pest-management element specifically.

End-of-lease pest control specifically

The end-of-lease pest treatment is what protects the bond. Where the tenancy agreement requires end-of-lease pest control, it usually means:

• A general pest treatment plus (if applicable) a flea treatment
• A written certificate as proof of treatment
• The certificate dated post-treatment and post-final-clean

The standard expectation, what’s included, what makes price move, and how to time the booking sit in the Pest Fox end-of-lease pest control in Adelaide article.

The certificate matters because it shifts the dispute resolution onto the agent. With a certificate, the tenant has documentary proof of compliance with the agreement; without one, the agent can withhold bond pending evidence — a default that costs the tenant time and (often) negotiation.

When you think the other party isn’t doing their bit

The dispute resolution path under the Act:

Written request first

The tenant who finds a pre-existing infestation, a structural rodent problem, or a termite sign should write to the landlord/agent within a reasonable period. The notification:

• Describes the issue (date observed, location, what was seen)
• Cites the relevant agreement clause and the Act’s “fit to live in” obligation
• Requests action within a reasonable period (sooner for termites or an infestation that affects how you can live in the home)
• Records the date of the notification

The landlord/agent should respond within a reasonable period. Most issues are resolved at this stage.

Consumer and Business Services (CBS) tenancy guidance

If the landlord/agent is unresponsive or refuses, Consumer and Business Services SA provides tenancy information and advice on your rights and obligations.

South Australian Civil and Administrative Tribunal (SACAT)

The formal adjudication body for residential tenancy disputes in SA. Either party can apply to SACAT — for example, about repairs or how the bond should be split at the end of a lease.

Free tenant advice

CBS can point you to free tenant advice services if you’re unsure of your position.

Body corporate and strata properties

Apartment, townhouse and unit-titled properties add a layer. The pest-responsibility analysis runs:

• Common-property pest issues route to the body corporate. Roof voids, common cavity walls, shared electrical risers, common landscaping, common waste areas, common entry points — all body-corp scope.
• In-unit pest issues route to the landlord/tenant analysis above. Inside the demised unit, the same SA Residential Tenancies Act framework applies between the unit’s landlord and tenant.
• Structural pest issues with cross-unit implications (e.g. German cockroach migration through common cavities, termite activity in common-property structural elements) typically require coordinated body-corp and individual-unit response. The body corp engages the licensed pest controller; individual units may share cost depending on the source unit.

A tenant in an apartment with a pest issue routes the first call to the landlord/agent, who then routes to the body corp where common-property is implicated.

Termites sit with the landlord

Worth saying directly because tenants do sometimes get asked.

Termites are a structural pest — they damage the building, which the landlord owns, and SA Government guidance lists termites as the landlord’s responsibility. AS 3660.2-2017 covers termite management for existing buildings, including regular inspections.

In general, a tenant shouldn’t:

• Reasonably be expected to pay for routine termite inspections
• Reasonably be expected to pay for termite treatment if termites are found
• Be expected to do termite treatment work themselves

A tenant who finds termite signs during tenancy should:

1. Stop disturbing the area immediately (do not spray, do not remove timber, do not break the mud tubes — disturbance scatters the colony and complicates identification)
2. Take photos with date stamps
3. Notify the landlord/agent in writing on the same day
4. Request inspection by a licensed pest controller within a reasonable period (immediate for visible activity)

The pre-purchase angle for buyers is parallel — covered in the Pest Fox pre-purchase termite inspection article.

FAQ

Who pays for pest control in an Adelaide rental? Under SA Government guidance, landlords are usually responsible for pests present at the start of a tenancy, for termites, and for sealing entry points; tenants are usually responsible for getting rid of pests that turn up during the tenancy and for keeping the premises reasonably clean. Your tenancy agreement can add reasonable extra conditions, such as an end-of-lease flea treatment where pets were kept. If you’re unsure, check with Consumer and Business Services.

Do I have to do pest control at the end of my Adelaide lease? Most Adelaide tenancy agreements include a clause requiring professional pest control at end of lease, typically with a flea treatment if pets have been kept. The clause is enforceable provided it is reasonable in scope. A general pest treatment plus a flea treatment (if pets) is the standard expectation; a written certificate dated post-treatment is what protects your bond. Detail in our end-of-lease pest control article.

Is the landlord responsible for cockroaches in my rental? If the cockroach infestation was already present at move-in, or originates from a structural defect (entry through a damaged weep-hole, migration through common cavity walls in a multi-tenancy building), it sits inside the landlord’s “fit to live in” obligation. If the infestation developed during your occupation and is traceable to your food storage or cleanliness practices, it sits inside your “reasonable cleanliness” obligation. Document the timeline and notify in writing if you believe the landlord is responsible.

What if I find termites in my rental property? Stop disturbing the area, photograph it, and notify the landlord/agent in writing the same day. Termites are the landlord’s responsibility under SA Government guidance, and termite work should be done by a licensed pest controller. The landlord should arrange a licensed termite inspection promptly — especially where activity is visible.

Can my real-estate agent demand pest control? The agent can require what the tenancy agreement reasonably specifies and what the Act allows. A reasonable clause requiring a professional general pest treatment and flea treatment at end of lease can generally be enforced. A clause trying to make the tenant responsible for termites may not be enforceable to the extent it conflicts with the Act. If the agent demands treatment beyond the agreement’s reasonable scope, written objection followed by Consumer and Business Services tenancy guidance is the path.

Where do I take a tenancy pest dispute that won’t resolve? Written request to the landlord/agent first. Then Consumer and Business Services (CBS) for tenancy guidance. Then the South Australian Civil and Administrative Tribunal (SACAT) if it still can’t be resolved. Most disputes resolve at the written-request stage; SACAT applications are reserved for the disputes that do not.
