Prevention.As our allotments are situated in a country setting, it is likely that we will always be prone to the occasional rat. However there are some tips to reduce the problem and stop them nesting and increasing in numbers i.e. never put cooked food / household waste in the compost bin and keep that compost bin regularly forked over, they don't like disturbance.
