Squirrels

A garden menace. Those tulips in the middle of my raised bed, any guess as to who planted them? Because it sure wasn't me. And at the base of my trellis do you see the little wasteland zone where my peas are supposed to be growing? I mean, I have long accepted that I have to pay some degree of nature tax but this is ridiculous. I planted peas EVERYWHERE and I can't find ONE peashoot. Not one. Can I evict the squirrels?
