CyKill Block,  Bromethalin Bait Products

Bromethalin was developed to combat a world-wide perceived problem of
rodent resistance to warfarin-like anticoagulant rodenticides. A highly potent
neurotoxin rodenticide that provides a lethal dose to rodents in a single
feeding. Bromethalin attacks the central nervous system; rodents usually
consume a lethal dose within a single night’s feeding, with the first dead
rodents appearing within 2 days. Available in bait blocks or place packs.
