Professional Rodent Control for Large Sites
When rodent activity is widespread, maintaining adequate bait coverage is critical. Contrac Bait Blocks are formulated using food-grade ingredients combined with bromadiolone to encourage reliable bait uptake by both rats and mice.
The block design features multiple gnawing edges and an integrated centre hole, making them easy to secure in bait stations while allowing rodents easy access to the bait.
Built for New Zealand Conditions
Contrac’s weather-resistant paraffin formulation helps the bait remain effective in a variety of indoor and outdoor environments. Whether placed in farm buildings, warehouses, storage facilities or outdoor bait stations, the blocks are designed to withstand challenging conditions.
Designed for Ongoing Rodent Management
The 8kg bucket is particularly suited to:
- Farms and lifestyle blocks
- Warehouses and distribution centres
- Food production facilities
- Commercial premises
- Pest control contractors
- Large residential properties
Why This Product Is Different
Many rodent baits require frequent replacement or are less suitable for large-scale baiting programmes.
Contrac combines:
- Proven bromadiolone active ingredient
- Single-feed performance
- Excellent bait acceptance
- All-weather durability
- Convenient bulk packaging
- Trusted professional-grade formulation
This makes it a practical solution for both active infestations and long-term rodent management.
What to Expect
Rodents typically begin feeding shortly after locating the bait.
As with most anticoagulant rodenticides, results are not immediate. Rodents generally consume the bait before returning to their nesting areas, with control occurring over the following days.
Continue monitoring bait stations and replacing bait until feeding activity has ceased.
How It Works
Contrac Bait Blocks contain Bromadiolone 0.005%, an anticoagulant rodenticide used for the control of rats and mice.
After consumption, the active ingredient affects the rodent’s blood clotting process. The delayed action helps prevent rodents from associating the bait with the outcome, supporting continued bait acceptance within the rodent population.
Recommended Usage
- Inspect the property for signs of rodent activity.
- Place bait securely in tamper-resistant bait stations.
- Position stations along walls, runways, nesting sites and feeding areas.
- Check bait regularly and replenish as required.
- Continue treatment until signs of rodent activity have ceased.
Always read and follow label directions.
Where to Use
Suitable for:
- Farms and agricultural buildings
- Warehouses and logistics facilities
- Commercial premises
- Food storage facilities
- Factories and workshops
- Large residential properties
- Around buildings with ongoing rodent activity
For best results, use within secure bait stations.
Important Safety Information
- Harmful if swallowed.
- Keep out of reach of children.
- Prevent access by pets and non-target animals.
- Store in the original container away from food and feed.
- Dispose of rodent carcasses, unused bait and packaging responsibly.
Important: This bait is recommended for situations where pets are unlikely to consume poisoned rodents or rodent carcasses. Consider alternative rodent control options where secondary poisoning may be a concern.
