It is helpful to minimise human and food smells (particularly on the rope handles) when working in areas where this is a risk. Or, wipe down affected nodes with 50-80% methylated spirits if extensive handling can not be avoided.
69 +We have experienced times where foxes (or some other animal) will dig up nodes and potentially carry them off for tens or hundreds of meteres. Being sanitary with the rope handles (e.g. not getting food grease on them) seems to help, as well as spraying the nodes and handles with methylated spirits et al. when deploying. There are other specialized products available depending on your environment.
