If you’ve relied on supermarket rat bait or a simple ongoing baiting setup in the past, things have changed.
In March 2026, the Australian Pesticides and Veterinary Medicines Authority (APVMA) introduced major changes affecting Second Generation Anticoagulant Rodenticides, often called SGARs. These are some of the stronger rodenticide products used for rat and mouse control.
For homeowners and businesses, this is more than a rule change on paper. It changes how certain products can be supplied, who can use them, and how rodent treatments need to be managed from here on.
On 10 March 2026, the APVMA certified that products containing second-generation anticoagulant rodenticides should be declared restricted chemical products.
That matters because restricted chemical products can only be purchased and used by people who meet specific training and licensing requirements.
The APVMA also announced a 12-month suspension of all SGAR product registrations from 24 March 2026, with strict national instructions applying during that period.
What does that mean for you?
The stronger rat and mouse bait products people were used to are now under much tighter control.
The main reason is safety.
The APVMA found that the current use of SGAR products presents unacceptable risks to non-target animals, including native wildlife, pets and livestock.
These stronger rodenticides can stay in a poisoned rodent’s body for a long time (up to 280 days). If that poisoned rodent is then eaten by an owl, kookaburra, goanna, pet or other animal, the poison can move up the food chain. That is secondary poisoning.
The changes are aimed at reducing that risk while the broader review of anticoagulant rodenticides continues.
For most households, the biggest change is access.
Products containing SGAR active ingredients are no longer something homeowners can expect to buy and use the way they once did. These stronger products are now being pushed into licensed, trained hands.
What does that mean for me?
It means DIY is now more limited, and it also means choosing a licensed pest controller is the sensible option.
A licensed pest controller knows how to inspect properly, place bait safely, reduce the risk to pets and wildlife, and work within the current rules. They can also look at the bigger picture, including entry points, proofing issues and why the rodent problem started in the first place.
If you need help, find a licensed pest controller near you at AEPMA.
For homeowners, the takeaway is pretty simple:

For commercial clients, the impact can be broader.
Property managers, food businesses, warehouses, strata sites and other commercial premises may now need a more documented and closely managed approach to rodent control. Treatments that once seemed routine may now need clearer justification, tighter service intervals and stricter handling.
That is especially important on sites where:
For commercial operators, this is not just about pest control for rodents. It is also about compliance, site safety and keeping the property properly managed.
One of the biggest changes is the move away from “set and forget” baiting.
Under the new rules, rodent control has to be more deliberate and more closely managed. That means the old approach of leaving stronger bait in place indefinitely is no longer the standard.
At Defender Pest Control Specialists, rodent services addressing an active infestation now follow a two-step model that fits this new environment.
Rodent Control Visit
The first step is control.
This visit focuses on inspection, confirming the extent of the activity, identifying entry points and placing appropriate control bait where needed. It is also where we look at proofing issues and property conditions that may be helping the infestation continue.
Rodent Maintenance Visit
The second step is maintenance.
Around 4 weeks later (no more than 35 days), a follow-up visit may be needed to remove control bait and replace it with more wildlife-friendly bait where appropriate for ongoing management.
This is a real change for customers. In many cases, rodent treatment now means more than one visit, rather than one appointment with bait left in place indefinitely.
That is not about making things more complicated. It is about using less pesticide where possible, keeping a closer eye on activity, and getting a safer result for people, pets and wildlife.
If you are dealing with rodent activity, the best move now is to get it assessed properly.
A practical next step looks like this:
For homes, that can mean protecting wiring, insulation and stored food.
For businesses, it can mean avoiding contamination risks, tenant complaints and repeat activity.
Defender Pest Control Specialists takes a straight-up, practical approach. We inspect the property properly, explain what has changed in plain English, and recommend a treatment plan that suits both the rules and the conditions on site.
These changes have left a lot of people unsure about what they can still buy, what still works, and what the right next step looks like.
That is where having a local, licensed pest controller helps.
At Defender Pest Control Specialists, we keep it simple. We inspect the site, work out what is actually going on, and explain the treatment plan clearly. No overcomplicating it. No vague advice. Just a practical way forward that fits the current rules.
Whether you are sorting out a problem at home or managing a commercial property with stricter compliance needs, we can help you get on top of it properly.

Not completely. The March 2026 changes focus on second-generation anticoagulant rodenticides. These products are now tightly restricted, with a 12-month suspension from 24 March 2026 and stricter controls on supply and use.
It is a stronger type of rodenticide used to control rats and mice. Common SGAR active ingredients include brodifacoum, bromadiolone, difenacoum, difethialone and flocoumafen.
The changes were made because the APVMA found unacceptable risks to non-target animals, including native wildlife, pets and livestock. Secondary poisoning is a major concern.
Access to SGAR products is now much tighter. These products are being restricted to people who meet training and licensing requirements, rather than broad consumer access.
In many cases, yes. The move away from long-term “set and forget” baiting means treatment is now more likely to involve an initial control visit and a follow-up maintenance visit.
Yes. Businesses, strata properties, warehouses and food-related sites may need a more structured rodent management approach, especially where compliance, documentation and ongoing monitoring matter.
If you have signs of rodent activity now, book an inspection now. Under the current rules, the right approach is a proper assessment and a treatment plan that matches the site and the regulations.
