Contrac Blox

Contrac Blox is ready to use wax block bait containing bromadiolone (0.005% w/w). A highly effective method to control rats and mice in all settings such as sewers, waste dumps and for the protection of public health, stored products and material. Bromadiolone is a potent second-generation anticoagulant rodenticide that was introduced to the UK in 1980. It's incredibly effective against rodents such as rats and mice.

To use Conrac Blox, you must hold a certificate showing compliance with UK rodenticide stewardship regime requirements.

For mice, place 6 to 28g per mouse bait station at 2 to 4-metre intervals. It is not recommended to bait for mice in outdoor open areas.

For Rats, use up to 225g of Contrac Blox per rat bait station at 5 to 10-metre intervals. You can even place the blocks directly into burrows.

Application – For Use by Trained Professionals Only: 

Instructions for use in and around buildings, outdoor open areas, and waste dumps:  For use in and around buildings, outdoor open areas, and waste dumps in tamper-resistant bait stations or covered bait points for the protection of goods in stock, food, health and materials.

Mice: 6 to 28 g of bait per baiting point at 2 to 4 metre intervals. Baiting for mice is not permitted in outdoor open areas, and waste dumps.
Rats: Up to 225 g of bait per baiting point at 5 to 10 metre intervals. Bait may be applied directly into burrows.

Consider preventive control measures (e.g. plug holes, remove potential food and drinking as far as possible) to improve product intake and reduce the likelihood of reinvasion. To reduce risk of secondary poisoning, search for and remove dead rodents during treatment at frequent intervals, in line with the recommendations provided by the relevant code of best practice. When placing bait stations close to surface waters (e.g. rivers, ponds, water channels, dykes, irrigation ditches) or water drainage systems, ensure that bait contact with water is avoided. Protect bait from the atmospheric conditions (e.g. rain, snow, etc.). Place the baiting points in areas not liable to flooding.

Replace any bait in baiting points in which bait has been damaged by water or contaminated by dirt. For outdoor use, baiting points must be covered and placed in strategic sites to minimise the exposure to non-target species and children. Cover or block the entrances of baited burrows to reduce the risks of bait being rejected and spilled. Follow any additional instructions provided by the CRRU UK Code of Best Practice (or equivalent). Do not use the product in pulsed baiting treatments. Sites under a permanent baiting regime should be inspected regularly in accordance with product label directions. The period between visits should be determined by the technician in charge but will not be longer than every four weeks when permanent baiting is conducted outdoors.

For permanent baiting follow any additional instructions provided by the CRRU Guidance on Permanent Baiting. Permanent baiting is strictly limited to sites with a high potential for reinvasion when other methods of control have proven insufficient. The permanent baiting strategy shall be periodically reviewed in the context of integrated pest management (IPM) and the assessment of the risk for re-infestation. Remove the remaining product at the end of treatment period (except when directly applied into burrows).

Instructions for use in sewers
For use only against brown rats (Rattus norvegicus), adult and juvenile. For the application in sewer systems, the ready-to-use bait is to be anchored or applied in bait stations or covered and protected bait points in a manner which prevents the bait from getting
into contact with waste water.

Do not use this product in pulsed baiting treatments. Up to 225 g per manhole. Baits must be applied in a way so that they do not come into contact with water and are not washed away.
