The new rodenticide regulations Australia 2026 have changed how homeowners and businesses across Melbourne can manage rodent infestations. The Australian Pesticides and Veterinary Medicines Authority (APVMA) has introduced major restrictions on second-generation anticoagulant rodenticides (SGARs) that affect anyone currently using rat or mouse baits at home.
What Are Second-Generation Anticoagulant Rodenticides (SGARs)?
Rodenticides are chemical products used to control rat and mouse infestations. They fall into two main categories:
First-generation anticoagulant rodenticides (FGARs) include products containing warfarin, coumatetralyl, diphacinone and chlorophacinone. These are weaker and require rodents to consume multiple doses over several days to be effective. Second-generation anticoagulant rodenticides (SGARs) are far more potent and were developed to overcome rodent resistance to first-generation products. They work by preventing blood from clotting, causing death through internal bleeding typically five to ten days after a lethal dose is consumed.
The five SGAR active ingredients now restricted in Australia are brodifacoum, bromadiolone, difenacoum, difethialone and flocoumafen. If any of these words appear on a rat bait product in your home, it is an SGAR.
Rodenticide Regulations Australia 2026: What Has Changed?
In March 2026 the APVMA made two significant announcements:
First, on 12 March 2026, the APVMA certified that all chemical products containing SGARs should be declared Restricted Chemical Products (RCPs) under Australian law. This means SGARs can only be purchased and used by licensed and authorised users — such as licensed pest control technicians.
Second, the registration of all SGAR products was suspended for one year from 24 March 2026. During this suspension period, SGAR products may only be supplied or used in accordance with instructions published in the APVMA Gazette No. 5, Tuesday 10 March 2026. These instructions are enforceable under state and territory legislation and apply nationally across Australia including Victoria.
In plain terms — the most powerful supermarket rat baits are being removed from shelves. Only licensed pest control professionals can buy and use them going forward.
Why Were SGARs Restricted?
The APVMA’s decision followed a four-year review process driven by growing concerns about secondary poisoning of Australian wildlife. When a rodent consumes an SGAR bait, the poison remains active in its body for an extended period. When native predators — such as owls, eagles, goannas and other birds of prey — consume a poisoned rodent, they also ingest the poison. This causes lethal or crippling doses in native animals that play a vital role in Australia’s ecosystem. The restrictions protect Australia’s native fauna, pets and livestock while ensuring rodent control remains effective through licensed professionals who are trained in safe application methods.
What Does This Mean for Melbourne Homeowners?
If you currently use SGAR-based rat or mouse baits purchased from a supermarket or hardware store, you should be aware of the following:
Products containing brodifacoum, bromadiolone, difenacoum, difethialone or flocoumafen are now restricted. These products should not be purchased or used by unlicensed individuals.
First-generation products containing warfarin, coumatetralyl, diphacinone and chlorophacinone may still be available to the public in the short term but are also under review by the APVMA.
For effective and legally compliant rodent control, engaging a licensed pest control technician is now the practical standard for Melbourne homeowners and businesses.
Why Professional Rodent Control Is Now More Important Than Ever
With the most effective rodenticides now restricted to licensed professionals, DIY rodent control has become significantly less effective. Licensed pest control technicians like those at Positive Pest Solutions have access to the full range of approved rodenticide products and are trained in their safe and effective application.
Our rodent control service in Melbourne includes:
- Thorough inspection of your property to identify rodent entry points.

- Identification and sealing of roof cavity, subfloor and wall entry points.
- Professional advice on preventing future rodent infestations.
- Follow-up service to ensure the infestation is fully resolved.

During autumn and winter, rats and mice actively seek shelter and warmth by moving into roof cavities, subfloors and inside Melbourne homes. This is the time of year when rodent infestations are most commonly reported across Melbourne’s South-Eastern suburbs.
Is Your Home at Risk?
Signs that you may have a rodent problem include:
- Scratching or scurrying sounds in your roof cavity or walls at night
- Droppings along skirting boards, in cupboards or near food storage areas
- Gnaw marks on food packaging, cables or timber
- Nesting materials such as shredded paper or insulation in confined spaces
- A strong musty odour in enclosed areas
If you notice any of these signs, it is important to act quickly. Rodents breed rapidly and a small infestation can become a serious problem within weeks.
