Hard to really appreciate what pests squirrels can be until they start finding their way into your house... and yes, I have killed one or two in my time... but mostly I just live and let live (and buy more sunflower seed to go around for the birds, squirrels and chipmunks). Much less work and aggravation than trying to get rid of them! The course where we golf is pretty much overrun with squirrels and from what I could tell today the sand traps looked like they've been burying their nuts and stuff in them for the winter; great, trees growing in the sand traps, that's all i need!
