Abstract
A study of the control has been made on Warfarin for house-rats in specified area. The chemical is consumed most by animals 3-4 days later, and dead animals are found most 6-7 days later baiting. Graphically the curve of consumption is parallel with that of the number of fatality. It implies that the baiting of this chemical must be carried out over rather a long period.
