Key Takeaways
- The APVMA suspended all second-generation anticoagulant rodenticide (SGAR) registrations for one year from 24 March 2026, making SGARs available only to licensed pest controllers under strict conditions.
- Warehouses and food businesses must now pivot to first-generation anticoagulant rodenticides (FGARs), mechanical traps, and robust Integrated Pest Management (IPM) protocols for autumn rodent control.
- All anticoagulant baits must now be placed in secured, lockable, tamper-resistant bait stations — mouse bait restricted to indoor use only, rat bait within two metres of buildings.
- Autumn in Australia (March–May) coincides with peak rodent ingress as temperatures drop, making proactive exclusion and monitoring critical.
- Food businesses subject to HACCP or third-party audits (SQF, BRC, FSSC 22000) should update pest management documentation immediately to reflect the regulatory change.
Understanding the APVMA SGAR Suspension
On 10 March 2026, the Australian Pesticides and Veterinary Medicines Authority (APVMA) certified that all chemical products containing second-generation anticoagulant rodenticides (SGARs) pose an unacceptable risk to non-target wildlife. The regulator reviewed more than 1,500 scientific studies and concluded that the five registered SGAR active constituents — brodifacoum, bromadiolone, difenacoum, difethialone, and flocoumafen — persist in animal tissues long enough to cause lethal secondary poisoning in native raptors, reptiles, and marsupials.
Effective 24 March 2026, all SGAR product registrations were suspended for one year. Major retailers including Bunnings, Coles, Woolworths, and Mitre 10 have removed these products from shelves. Only licensed pest management technicians may now purchase and deploy SGARs, and only under legally enforceable conditions that override existing product labels.
New Conditions Affecting All Anticoagulant Rodenticides
- All baits must be placed in secured, lockable, tamper-resistant bait stations.
- Mouse baits may only be placed inside buildings — external use is prohibited.
- Rat bait stations must be positioned within two metres of building exteriors.
- Use is limited to a maximum of 35 consecutive days without documented reassessment.
These conditions apply to both SGARs (where licensed use continues) and FGARs, signalling a broader regulatory shift toward accountable, science-based rodent management.
Why Autumn Is a Critical Period for Australian Warehouses
Australia's autumn — March through May — triggers predictable rodent behaviour changes. As overnight temperatures fall, both the Norway rat (Rattus norvegicus) and the roof rat (Rattus rattus) shift from outdoor foraging to seeking shelter, warmth, and reliable food sources inside commercial structures. The house mouse (Mus musculus) follows a similar pattern but can exploit gaps as small as 6 mm.
Warehouses and food distribution centres are particularly vulnerable because they offer harbourage (racking, palletised goods, insulation cavities), water sources (condensation, cleaning drains), and abundant food. A single breeding pair of mice can produce over 60 offspring in a year under favourable conditions, making early autumn the decisive window for intervention.

Compliant Chemical Control Options
First-Generation Anticoagulant Rodenticides (FGARs)
Three FGAR active constituents remain registered for commercial and domestic use in Australia: warfarin, coumatetralyl, and diphacinone. Unlike SGARs, FGARs require rodents to consume multiple doses over several days to reach a lethal threshold. Their shorter tissue half-life significantly reduces secondary poisoning risk — a key reason the APVMA has maintained their availability.
For warehouse and food business operators, FGARs remain a legitimate component of a baiting programme when used inside locked bait stations and documented in pest management logs. However, FGARs are less potent than SGARs, and established rodent populations may require longer baiting periods. The 35-day reassessment rule applies equally, so operators must monitor consumption data and rotate strategies if bait uptake stalls.
Non-Anticoagulant Rodenticides
Products containing cholecalciferol (vitamin D3) or zinc phosphide offer non-anticoagulant lethal control options. Cholecalciferol-based baits cause hypercalcaemia in rodents and carry a substantially lower secondary poisoning profile. Zinc phosphide is an acute toxicant used primarily in agricultural settings. Both require careful handling, appropriate PPE, and compliance with label directions.
Mechanical and Non-Chemical Control Methods
The SGAR suspension accelerates a trend already well-established in IPM science: mechanical and environmental controls often outperform chemical-only strategies in commercial settings.
Snap Traps and Electronic Traps
Traditional snap traps remain among the most effective rodent control devices when deployed correctly. For warehouses, commercial-grade snap traps should be placed along confirmed runways — typically at wall-floor junctions, behind racking, and near loading dock entries. Electronic traps deliver a lethal charge and can be connected to digital monitoring platforms that send real-time alerts when a capture occurs, reducing the labour cost of manual inspections.
Glue Boards
Glue boards are permitted in Australia but face increasing scrutiny on animal welfare grounds. Their use in food-handling environments should be limited to monitoring rather than primary control, and boards must be checked at least daily.
Digital Monitoring Systems
Remote monitoring technology — including infrared sensors, camera traps, and connected bait station sensors — enables 24/7 surveillance of rodent activity across large warehouse footprints. These systems generate timestamped data logs that satisfy audit requirements under HACCP, BRC, and SQF standards.
Exclusion: The Foundation of Autumn Rodent Defence
No chemical or mechanical programme succeeds without structural exclusion. The following checklist applies to warehouses and food businesses preparing for autumn:
- Doors and dock levellers: Install or replace brush strips and rubber seals on all roller doors, personnel doors, and dock levellers. Gaps exceeding 6 mm for mice or 12 mm for rats must be sealed.
- Service penetrations: Seal gaps around pipes, cables, and conduits with rodent-proof materials — stainless steel wool, metal flashing, or cement. Expanding foam alone is insufficient.
- Drainage: Fit one-way valves or grates on floor drains. Norway rats frequently enter buildings through sewer and drainage systems.
- Vegetation management: Cut back vegetation to at least one metre from building perimeters to eliminate harbourage and improve bait station visibility.
- Roof and eave access: Inspect and seal gaps in roof sheeting, ridge caps, and turbine ventilator bases — primary entry points for roof rats.

Sanitation and Harbourage Reduction
Warehouses and food businesses should treat autumn as a trigger for a full sanitation audit:
- Eliminate food debris beneath racking, conveyor systems, and processing equipment.
- Store all ingredients and finished goods on pallets at least 450 mm from walls to allow inspection access.
- Remove disused pallets, cardboard, and packaging materials that provide nesting substrate.
- Ensure waste bins are fitted with tight-closing lids and emptied on a schedule that prevents overnight accumulation.
- Repair water leaks promptly — rodents require a reliable water source and will nest near dripping taps or condensation points.
Documentation and Audit Compliance
The SGAR suspension creates an immediate documentation gap for any food business relying on SGAR-based programmes. Operators should take the following steps:
- Update the pest management plan to reference current APVMA conditions, including the 35-day reassessment rule and bait station placement restrictions.
- Ensure the contracted pest management provider holds appropriate state or territory licensing to use any restricted chemical products.
- Maintain bait station maps showing compliant placement distances.
- Record all trap checks, bait consumption data, and corrective actions in a centralised digital or paper log accessible to auditors.
- Brief relevant staff on regulatory changes — awareness reduces the risk of non-compliant bait purchases or ad-hoc rodent control attempts.

When to Call a Licensed Pest Professional
The regulatory landscape now makes professional engagement more important than ever. A licensed pest management technician should be engaged when:
- Rodent activity persists beyond 35 days of FGAR baiting or trapping.
- Evidence of structural entry points exceeds the capacity of in-house maintenance teams.
- A food safety audit is imminent and the pest management plan requires regulatory updates.
- SGARs are deemed necessary — only licensed technicians may legally purchase and deploy these products under the current suspension conditions.
- Rodent activity is detected in sensitive zones such as ingredient storage, processing lines, or finished goods areas.
Engaging an accredited provider affiliated with the Australian Environmental Pest Managers Association (AEPMA) ensures compliance with both APVMA conditions and state-level pesticide regulations.
Building a Post-SGAR Rodent Management Programme
The APVMA suspension is not merely a temporary inconvenience — it signals a permanent shift toward lower-toxicity, evidence-based rodent control. Warehouse and food business operators should use autumn 2026 as the catalyst to build programmes anchored in exclusion, sanitation, monitoring technology, and targeted chemical intervention as a last resort. This approach aligns with global IPM best practice and positions businesses favourably for future regulatory tightening expected when the APVMA delivers its full reconsideration decision, anticipated in early 2027.
