SureKill®’s Assault Blocks contain the single-feed bromethalin formulation, which makes rodents want to stop feeding after consuming a lethal dose, using less bait overall. Assault Blocks have a quick knockdown when compared to other anticoagulants, with results in as little as 2 days after consuming a toxic dose. Bromethalin is great for controlling rodents withresistance to anticoagulants.
