They are also very good at getting rid of field mice and voles. Since the white footed field mouse is the biggest vector of deer ticks, which carry Lyme disease in the US, it is beneficial to have foxes on your property and they eat a lot more mice and voles than rabbits and pheasants and they are pretty good at catching groundhogs which are the bane of farmers in my state. So far as rabies goes, yes foxes can get rabies, however raccoons and skunks and feral cats are bigger rabies vectors.
