New Rat Bait Laws in Australia: What’s Changed and What It Means for You

If you’ve gone to grab rat bait at Bunnings or your local supermarket lately and found the shelf half empty, you’re not imagining it. The rules around rodent bait in Australia have changed, and it’s already affecting what Sydney homeowners can buy.

Here’s what’s happened and what it means for keeping rats and mice out of your home.

What’s Actually Changed

In March 2026, the Australian Pesticides and Veterinary Medicines Authority (APVMA) — the body that regulates pesticides in Australia — moved to restrict a group of rat baits called Second Generation Anticoagulant Rodenticides, or SGARs.

Two things happened. On 12 March 2026, the APVMA certified that these baits should become Restricted Chemical Products — professional, licensed use only. Then on 24 March 2026, it suspended the registration of every SGAR product for 12 months as an interim measure while the longer-term change is worked through.

In plain terms: the strong rat baits that used to sit on the shelf next to the fly spray are being pulled from general retail sale.

The five active ingredients caught up in this are brodifacoum, bromadiolone, difenacoum, difethialone and flocoumafen. If you flip over an old box of bait in the shed, there’s a good chance you’ll see one of those names.

Why the Rules Changed

This isn’t red tape for the sake of it. SGARs are very good at killing rodents, but they don’t stop there.

When a rat eats the bait, the poison stays in its body. If an owl, a kookaburra, or a family pet then eats that rat — or gets into the bait directly — they cop a dose too. This is called secondary poisoning, and it’s been showing up in Australian wildlife for years. Native owls and other predators have been hit hard.

That’s the real driver behind the change. These baits work, but the harm to non-target animals is the problem the regulator is trying to fix.

What It Means for You

If you’ve relied on store-bought bait to deal with a rat problem, that option is narrowing. The products being withdrawn are the heavy hitters, and they won’t be on the shelf the way they used to be.

Here’s the part most people don’t realise: poison was never the best first move anyway. The most effective way to deal with rodents long-term is to stop them getting in, then use targeted baiting only where it’s genuinely needed — and only where it’s handled properly. (We’ve covered how to rodent-proof your home in a separate guide.)

The Bait We Use — Selontra

At So Pest Off, the bait we use across Sydney is Selontra. It’s a professional product made by BASF, and it works differently to the baits being withdrawn.

Selontra’s active ingredient is cholecalciferol — Vitamin D3 — not an anticoagulant. Because it’s not an SGAR, it isn’t caught up in the suspension, and it carries a much lower risk of the secondary poisoning that got the older baits restricted. It’s a Schedule 7 product, which means professional use only — you won’t find it on a supermarket shelf, and that’s by design.

We use it as part of a managed program: in tamper-resistant stations, with placement and timing controlled, and never left running indefinitely. That kind of oversight is exactly what a professional program gives you and a DIY box never did.

Why We Only Service Ongoing Programs

Because of how these products now work, we can only take on rodent baiting for clients on a regular maintenance program — not one-off “pour some poison in the roof” jobs.

That’s not us being difficult. It’s the responsible way to use a professional bait: monitored, refilled when needed, and combined with proofing your home so the problem doesn’t just come straight back. One-off baiting with no follow-up is exactly the approach the new rules are moving away from.

For commercial sites — restaurants especially — we can run Bluetooth-monitored bait stations that track exactly where rodents are moving in and out. That data tells us where to proof, so we’re sealing the real entry points instead of guessing. (More on that in our rodent-proofing guide.)

Frequently Asked Questions

Can I still buy rat bait at the supermarket in Australia?
The strongest baits — Second Generation Anticoagulant Rodenticides — are being withdrawn from general retail sale following the APVMA’s March 2026 decision. Some milder products may still be available, but the heavy-duty baits people relied on are being phased out over 12 months. For a serious rodent problem, a licensed pest controller is now the reliable option.

Why were rat baits restricted in Australia?

They weren’t fully banned — they were restricted to professional use. The APVMA acted because these baits cause secondary poisoning: native owls, other predators and family pets are harmed when they eat poisoned rodents or get into the bait itself. The change is designed to protect non-target animals while still allowing controlled professional use.

Is Selontra affected by the new rules?

No. Selontra’s active ingredient is cholecalciferol (Vitamin D3), not an anticoagulant, so it sits outside the SGAR suspension. It’s a professional-use product we apply as part of a managed baiting program, with a lower secondary-poisoning risk than the baits being withdrawn.

Do I need a professional for rodent control now?

For anything beyond the odd stray mouse, yes. With the strongest baits moving to professional-only, and with proofing being the real long-term fix, a licensed pest controller gives you the safer and more effective result. Our rodent control service covers it — or call So Pest Off on 0410 244 244 to talk through your situation.

The Takeaway

The rat bait rules have changed for good reason — the old products were quietly poisoning the wrong animals. The bait still exists, it’s just in professional hands now, used properly and paired with proofing your home.
