I have created several garden in very urban environments, and all is well, no voles no deer just those dam squirrels. Short of filling the soil with sharp shreds of broken glass, and 120 volts of electricity does anyone know how to deal with these rodents? The Police said it was OK to shoot them, yes really, the next county over would put me in jail for a year. Anyone have any ideas as I don't have a clue, it seems to thousands of this dam tree rats. They eat the same stuff rats do and rats are not tolerated why squirrels.
