What non-lethal methods work best to keep city squirrels away from tomatoes? It is a serious problem here. I wouldn't mind sharing some tomatoes, but the squirrels here are very rude and do not share. And actually taunt. Taking a bite out of a perfectly good tomato and then leaving it.
Building a wire cage probably is the best method, but I hear they can even get through those. And I'm not all that handy at building things.
Last year, putting soaking a rag with vinegar about every 3 or so days seemed to work for a while. Though at the end of the summer, even that was not deterring them that well.
