Im having a squirrel problem...specifically young ones. I have a lot of container plants and every year they dig in them and plant nuts. That much I can deal with however, this year they are obsessed with eating my sweet potatoe vines. I did not have this problem last year and I do not know what I can do to deter them from chewing on them any more. I know mari****s are supposed to deter pests but they already ate mine (evil squirrels). HELP! HELP!
