Hi Uli, If you ask the question on the web: " Does Vitamin D3 kill mice", this is the answer: This is one of the most dangerous *mouse* and rat poisons on the market. *Cholecalciferol*, or activated *vitamin D3*, causes a life-threateningly high calcium and phosphorus level in the body, resulting in severe, acute kidney failure, cardiovascular abnormalities, and tissue mineralization. The cholecalciferol, better known as *vitamin D3*, is used as a health supplement in humans. Mix Vitamin D with peanut butter. Dead rodents are not poisonous to predators. It is sad that we have to resort to eliminating these little critters but I know first hand what kind of damage they are capable of doing.
