Microencapsulated warfarin, a hydroxycoumarin anticoagulant rodenticide, is contained in all Rodex™ bait formulations. In early research trials, rat acceptance of microencapsulated warfarin baits was 3 to 10 times greater than uncoated warfarin baits. This anticoagulant is a multi-feed chronic rodenticide, and is considered the lowest hazard to non-target animals of any anti-coagulant rodenticide. Rodex bait formulations are available in pellets and blocks.
