Muizen- en rattengif: Brodifacoum dodelijk voor uilen

Evidence from the literature is presented that secondary poisoning of owls is likely to occur whenever Brodifacoum is used against rodents. This agent replaces Warfarin and is to be found in the rodenticide Klerat. Several alternatives are presented to avoid the use of anticoagulents at farms and houses in the countryside, such as traps, cats and mice-catching boxes which cannot be entered by owls (with layout how to make one).
