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.
