SKU: ratabate-paste

Price range: $26.75 through $235.39 incl GST

Key Benefits
  • Highly palatable - made from food grade ingredients
  • Low risk of secondary poisoning - diphacinone has a short half life compared with second generation anticoagulants
  • No bait caching - the paste format encourages rats to feed inside bait stations rather than carry bait away.
  • Trusted by professionals - used by the Department of Conservation and leading pest‑control experts.
  • Readily available antidote - Vitamin K is an effective treatment if accidental poisoning occurs.
  • No Controlled Substance Licence required – easier to use than many other vertebrate toxic agents.

RatAbate paste – for rat control

RatAbate Paste is a highly palatable bait that delivers effective rat control.

The active ingredient, Diphacinone, is a first‑generation anticoagulant. Because these anticoagulants have a short half‑life, they carry a much lower risk of secondary poisoning, making RatAbate a smart option for farms and environmentally conscious users.

For best results, place RatAbate Paste inside purpose‑built rat bait stations such as our Run Through or Zig Zag models.

For more options, see our range of rodent control products.

Active ingredient

  • Diphacinone – 0.05g/kg

Features

  • Highly palatable – rats love it!
  • Low risk of secondary poisoning – its short half-life* compares favourably to other toxins
  • Prevents target animals hiding and storing it (bait caching) – the paste format encourages bait station feeding instead
  • Used by experts – the Department of Conservation and other leading conservationists and pest controllers
  • Antidote is readily available – Vitamin K
  • No Controlled Substance Licence (CSL) required

Environmental impact

  • Breaks down a lot faster than other toxins – its half-life* in tissue and blood is only 3 days. Brodifacoum, the most commonly used second-generation anticoagulant, is 130-300 days.
  • Minimal risk of secondary poisoning
  • Minimal risk to native birds and non-target species

Safety for handlers

How to use RatAbate paste

History

  • Controlling rats in New Zealand since 2006

Read the Safety Data Sheet (SDS), which is available on our website. Put gloves on before applying.

Use appropriate bait stations, such as Run Through or Philproof, to minimise access to baits by non-target animals. If necessary, fit the excluder baffle for the Philproof to exclude possums and birds.

Bait should be placed for rats using a minimum of a 50 x 50 metre grid in a rural setting. In an urban setting place bait stations along walls, near compost bins or other areas where activity has been observed. Place enough bait to ensure that there is an uninterrupted supply of bait for all rats for at least ten days, or until rat activity ceases.

 

What active ingredient does RatAbate use?

RatAbate contains Diphacinone, a first‑generation anticoagulant. Its short half‑life means it carries a much lower risk of secondary poisoning, making it suitable for farms and environmentally conscious users.

How long has RatAbate Paste been used for rat control in New Zealand?

RatAbate Paste has been used to control rats in New Zealand since 2006, giving it a long, proven history of effective performance.

Why is Diphacinone considered environmentally safer?

Diphacinone has a short biological half‑life — around 3 days in tissue and blood. Compared with Brodifacoum (130–300 days), this means:

  • Minimal risk of secondary poisoning
  • Reduced long‑term environmental persistence
  • Lower risk to native birds and non‑target species

How much RatAbate Paste is dangerous to dogs?

Because RatAbate Paste contains only 0.05% diphacinone, a dog must eat a large amount of paste to reach a dangerous dose. The risk depends heavily on the dog’s size.

Small dogs (5–10 kg) are at the highest risk because their body weight is low, and would need to eat 200–400 g of paste to reach a potentially dangerous dose.  This is equivalent to most or all of the paste inside a bait station.

Medium dogs (10–25 kg) would need to eat 400–900 g of paste. This usually means multiple bait stations or a large tub of paste. Accidental poisoning is uncommon unless a dog gains direct access to stored bait.

Large dogs (25–40 kg) would need to eat 1–1.5 kg of paste. This is significantly more than a dog could access from a properly used bait station. Large dogs are at lower risk from single‑event ingestion.

Very large dogs (40+ kg) would need well over 1.5 kg of paste. Primary poisoning is unlikely unless the dog consumes a large quantity of loose or spilled bait.

Important Notes

  • These amounts are estimates, based on typical diphacinone LD50 ranges for dogs and the 0.05% concentration in RatAbate Paste.
  • Small tastes or minor exposure are very unlikely to cause harm.
  • Vitamin K is an effective antidote if treatment begins early.
  • Using enclosed bait stations is the best way to prevent dog access.
  • Dogs are not fully safe from primary poisoning, but they must consume large quantities of RatAbate Paste to reach dangerous levels. Proper bait station use makes accidental ingestion very unlikely.

Our advice is always to contact a vet urgently if you suspect your pet has ingested any toxin.

Is RatAbate Paste safe for native wildlife?

When used correctly in bait stations, RatAbate Paste presents minimal risk to native birds and non‑target species due to its short half‑life and reduced secondary‑poisoning potential.

Why do birds eat RatAbate Paste?

RatAbate Paste contains grains and sugars that attract rats—but these ingredients also appeal to many bird species. Birds will readily sample paste if it is accessible.

How can I reduce bird access to paste bait?

  • To reduce bird interference, use extended entrance tunnels on run‑through bait stations.
  • For Philproof stations, a bird‑exclusion floor can prevent birds from reaching the bait.

Can small birds like waxeyes or silvereyes be harmed by RatAbate Paste?

Waxeyes typically weigh 12–20 g and would need to consume around 80–130 g of RatAbate Paste to reach an LD50. This means lethality is low, though repeated feeding could cause sublethal clotting effects.

Fantails weigh only 8–10 g and would need 50–70 g of paste to reach an LD50. They rarely eat paste, and the expected outcome is very low lethality with minimal sublethal risk.

House sparrows (27–30 g) would need 160–190 g of paste to reach an LD50. They have a moderate sublethal risk, and occasional mortality is possible if they repeatedly feed.

Blackbirds weigh 90–110 g and would need 520–700 g of paste to reach an LD50. They face a moderate to high sublethal risk, and mortality is possible with repeated feeding.

Starlings (75–85 g) would need 440–600 g of paste to reach an LD50. They have a moderate risk, with mortality possible if they feed over several days.

Mynas weigh 100–120 g and would need 600–760 g of paste to reach an LD50. They have a higher risk, and mortality is plausible if they repeatedly consume paste.
