Hi ! The number one way is to have a fence around it ! I use a product called liquid fence it is made from egg shell and garlic , it stinks when you first spray it . It says use 1 time a month , I use it about every 10 days . I buy it in the concentrated form it is less expensive . It works for me ... I spoke to people that said it didn't work for them...
