Grey squirrels are a destructive, invasive, non-native species. The damage they do to our native hardwoods, when the trees are between 15 and 25 years old and at their most vulnerable, is well documented, as is their predation of the nests of woodland birds. These are reasons enough to control them, before we add in the fact that they are responsible for the demise of our native red squirrels. They will also damage feeders and drinkers and are happy to spend their days chewing holes in the alkathene water pipes in our pens.
April is the month to get on top
