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.
