Generation Mini Blocks with difethialone is a single feed bait, second-generation anticoagulant rodenticide. As a single-feed bait, it takes just one feeding to kill the rodent. Generation Mini Blocks with more food-grade grains and flavorings and less wax and dye are very appealing to rodents. Mice, Roof rats, and Norway rats are readily attracted to this bait. Generation Mini Blocks have a center hole for securing on rods in bait stations to prevent translocating the bait. They have rodent-gnaw able edges for increased attraction. Effective and palatable for rats and mice. Contains the active ingredient difethialone (25 ppm); Vitamin K1 is the antidote. Designed with rodent gnawing edges and a center hole for securing in bait stations. Smaller 20g block size.
