Ready to use – fast acting Contrac Blox Rat Bait for use in and around homes, agricultural, commercial and industrial buildings. A true block rat bait containing the anti-coagulant rat bait bromadiolone.

Contrac Blox is a single-feeding anticoagulant rodenticide containing the active ingredient, Bromadiolone. It is an excellent clean-out and maintenance bait to control mice and rats, including warfarin-resistant Norway rats.

Contrac Blox is specially formulated with an optimal blend of food-grade ingredients and a small amount of paraffin. The result is a highly palatable, yet weatherable, bait that works well in wet and dry conditions.

Bait acceptance with Contrac is superior due to its highly palatable formulation. Plus, manufactured with Bell's extrusion process, Contrac Blox has multiple edges that appeal to a rodent's desire to gnaw. Rodents can consume a lethal dose in just one feeding.

Bait shyness is not a problem with Contrac because mortality occurs a few days after bait is consumed. Contrac is also less toxic to non-target animals, in both primary and secondary poisoning situations, than other single-feeding anticoagulants. The antidote, Vitamin K1, is readily available and there is a time factor for treatment.

For ease of use, the pre-measured 28g BLOX has a hole in the center which lets technicians place it on bait securing rods in tamper-resistant bait stations. It can also be nailed or wired to rafters and ceilings or placed in tight locations.

Most suitable for controlling rats, but is also effective against mice. Place Contrac Blox Rat Bait in rat bait station and observe rat bait take. Replace blocks that become more than 50% eaten to minimise the chance of blocks being removed from rat bait stations. Maintain the supply of Contrac Blox Rat Bait until rat bait is no longer eaten.

Where continuous control is required, maintain a steady supply of blocks, replacing uneaten Contrac Blox Rat Bait at monthly intervals to ensure rat bait remains fresh. Unlike egg-shaped rat baits, Contrac Blox Rat Bait cannot be rolled away and are manufactured with a hole in the middle so they can be easily nailed down to prevent ‘stealing and burying away from the site’

FREQUENTLY ASKED QUESTIONS

What is the difference between Contrac (Green Blocks) and Ditrac (Red Blocks)?

These two baits / poisons are made by the same company but feature two different active constituents. Contrac contains Bromadiolone and Ditrac contains Brodifacoum. As a result, Ditrac is approximately 4 times stronger than Contrac. Contrac blocks are also slightly bigger and denser than Ditrac, so as a result you will get more blocks / kg with Ditrac.

Why would I choose one or the other? What is the best bait for me?

There are several reasons why you would choose either Contrac or Ditrac bait. Firstly due to Contrac being less toxic than Ditrac this makes it safer for use around non-target animals that could potentially consume the bait directly (primary poisoning) or consume rats and mice that have consumed the bait (secondary poisoning). Ditrac on the other hand, being 4 times stronger than Contrac, would be the recommended poison of choice where there is little or no risk of poisoning other non-target animals. Ditrac is also recommended where a fast ‘clean-out’ of persistent problems is required.

What is Bromadiolone?

Bromadiolone is a potent rodenticide. It is a second-generation 4-hydroxycoumarin derivative, often called a "super-warfarin" for its added potency and tendency to accumulate in the liver of the poisoned organism. When first introduced to the UK market in 1980, it was effective against the populations that had become resistant to the first generation anticoagulants.

The product may be used both indoors and outdoors for rats and mice.

Bromadiolone can be absorbed through the digestive tract, through the lungs, or through skin contact. The pesticide is generally given orally. The substance is a vitamin K antagonist. The lack of vitamin K in the circulatory system reduces blood clotting and will cause death in large dosages due to internal hemorrhaging.
