Tomcat II All-Weather Blox 1.8kg: Brodifacoum Rat Bait Blocks and Mouse Poison

Tomcat II All-Weather Blox: Single-Feed Rodenticide for Wet or Dry Conditions

Tomcat II All-Weather Blox is a single-feed anticoagulant rodenticide designed to control rats and mice in wet or dry conditions. Each red block contains 0.05g/kg brodifacoum, the strongest of the common anticoagulant baits, and controls rodents resistant to warfarin and other older baits. The blocks also contain denatonium benzoate, a bittering agent that helps deter accidental eating by people. Made in the USA by Bell Laboratories and supplied in Australia by Barmac, this 1.8kg tub is for use in and around domestic, commercial, agricultural and industrial buildings.

Tomcat Green or Tomcat II Red: Which Should You Choose?

• Tomcat All-Weather Blox (Green): bromadiolone, a single-feed anticoagulant with lower toxicity to non-target animals. A good choice for routine baiting around homes.
• Tomcat II All-Weather Blox (Red): brodifacoum, a stronger single-feed anticoagulant. Best for heavy or persistent infestations, and where rodents have stopped responding to other baits.

Because brodifacoum is more potent and lasts longer in the body, it carries a higher risk to pets and wildlife that eat bait or poisoned rodents. Use Tomcat II where its extra strength is needed, and always inside secured bait stations.

Multi-Edge Blocks for Damp and Dry Areas

Tomcat II Blox are extruded into hard, multi-edged blocks that combine the taste appeal of a meal bait with the weather resistance of a wax bait. The ridged edges encourage rats and mice to gnaw, and the blocks hold up in damp sheds, sub-floors, drains and farm buildings where soft baits break down. A hole through each block lets you thread it onto the rods inside a bait station, or wire or nail it in place, so rodents can't drag it away.

Where Should You Place Rat Poison?

• Along walls, skirting boards and fence lines, where rodents travel
• Near burrows, holes and entry points into buildings
• In dark, sheltered spots such as roof voids, sub-floors, behind appliances and in sheds
• Close to droppings, gnaw marks and grease marks

Always place bait inside tamper-resistant bait stations, never in the open, and keep stations away from food, food preparation areas and animal feed.

What Is the Fastest Poison to Kill a Rat?

No registered rat poison kills instantly. Anticoagulants like brodifacoum work over a few days by design, so rodents don't link the bait with illness and the rest of the colony keeps feeding. If you need a quicker result for one or two rats, snap traps work faster. For an established colony, single-feed baits like Tomcat II are more effective overall.

How to Use Tomcat II Blox

• Wear gloves when handling blocks, to protect your hands and avoid leaving human scent.
• Secure blocks on the rods of lockable, tamper-resistant bait stations.
• Use the number of blocks and spacing between bait points given on the label for rats or mice.
• Check stations regularly and replace eaten blocks while feeding continues.
• Keep baiting until feeding stops, then remove remaining bait.
• Collect dead rodents with gloves and dispose of them as the label directs.

Safety

Read the label before opening or using. Keep out of reach of children. Brodifacoum is hazardous to dogs, cats, poultry, livestock and native wildlife, including through eating poisoned rodents. Use bait only inside secured stations, never in the open. The antidote is Vitamin K1, given under medical or veterinary supervision. If poisoning occurs, contact a doctor or vet, or call the Poisons Information Centre on 13 11 26.

Frequently Asked Questions

What is Tomcat II All-Weather Blox?

It's a single-feed anticoagulant rodenticide containing 0.05g/kg brodifacoum, made as red, weather-resistant blocks to control rats and mice in wet or dry conditions.

What is the difference between Tomcat Green and Tomcat II Red?

Tomcat Green uses bromadiolone, which has lower toxicity to non-target animals. Tomcat II Red uses brodifacoum, a stronger single-feed anticoagulant for heavy or resistant infestations.

What poison is best to kill rats?

It depends on the problem. For routine baiting, bromadiolone blocks are often enough. For large or persistent infestations, or rodents that ignore other baits, brodifacoum blocks like Tomcat II are stronger. Always use bait stations.

What poison kills rats and mice?

Anticoagulant baits such as brodifacoum, bromadiolone and difenacoum are the most widely used in Australia. Tomcat II controls both rats and mice with brodifacoum.

What is the fastest poison to kill a rat?

No registered poison kills instantly. Single-feed anticoagulants like brodifacoum take a few days, which stops bait shyness. Snap traps give a quicker result for small numbers of rats.

Where should you place rat poison?

Inside tamper-resistant bait stations along walls, near burrows and entry points, and in dark, sheltered spots where you see droppings or gnaw marks. Never place bait in the open.

Does Tomcat II work on bait-resistant rodents?

Yes. Brodifacoum controls rats and mice resistant to warfarin and other older anticoagulants.
