- placing on a first day cholecalciferol baits at bait points in the environment to be protected and leaving the baits for a baiting time at the bait points,
- wherein the baiting time is 7 days or less;
- wherein the cholecalciferol baits are placed only on the first day of the baiting time and optionally on up to 3 further times within the baiting time in the environment to be protected;
- wherein the cholecalciferol bait comprises 600 to 1000 ppm of cholecalciferol;
- wherein for controlling mice, 1 to 10 cholecalciferol baits are placed at each bait point and the bait points are located in intervals of 0.3 to 10 m;
- wherein for controlling rats, 1 to 30 cholecalciferol baits are placed at each bait point and the bait points are located in intervals of 1 to 25 m;
- wherein the cholecalciferol baits have a palatability of at least 2.0,
- wherein the method reduces the number of rats or mice by at least 90% in the environment to be protected at the end of the baiting time, and
