(1) Local authorities were asked to split rodenticide use by setting but in some cases this wasn't possible and data were supplied in relation to mixed domestic and industrial use, one LA stated that their domestic figure might include some industrial data and it is possible that this is the case for some other LAs that only supplied domestic data.
