Storm is a second generation anticoagulant rodenticide. Only a very small amount is needed to kill a rat or mouse, and a lethal dose can be eaten in a single feed. Rodents then die three to five days after taking the bait. With some other rodenticides, rodents die more than a week after taking the bait. Storm is a highly palatable and durable bait block that is quick and easy to use. A central hole allows each block to be anchored securely in baiting points for the best targeting and to prevent removal. The potency of Storm, when used in the pulse baiting technique, means that while baits are placed in as many points as possible, less bait is required to achieve control. This results in Strom being more economical than other rodenticides.
