Contrac Blox is a highly palatable, specially formulated single feed  rodenticide containing bromadiolone.  Contrac Blox is a very effective extermination and maintenance bait for rats and mice. The special formula uses an optimal blend of food grade ingredients and a small amount of paraffin that results in a highly palatable rodent bait that works well in wet and dry conditions. Contrac Blox kills in a single feed and has multiple edges for easy gnawing from the rodents themselves.

Health and Safety Impacts:

  • May be harmful if swallowed
  • Keep out of reach of children and domestic animals, particularly cats, dogs, pigs and birds
  • Less toxic to non target animals in primary and secondary poisoning situations than other single feeding anticoagulants
  • If swallowed do not induce vomiting, contact the National Poisons Centre on 0800 POISON (0800 764 766) or a doctor immediately

How to Use:

  • Firstly determine the severity of the infestation – droppings are a good indicator of infestation size, and varying faeces size indicate that juveniles and adults are present, many droppings indicate a large infestation
  • Concentrate baiting in high activity areas
  • Store in the original contrainer, tightly closed and away from foodstuffs
  • Avoid all contact by mouth, wash hands and exposed skin before meals, smoking and after any contact
  • Do not use where food or feed could become contaminated
