fox urine is also expensive, my co-op sells it for $40 a bottle, a squirrel baffle is cheaper, so is a hav a heart trap, squirrel size, or just moving your bird feeders. i hate stupid squirrels too, i caught one IN my coop eating the chick food!
we sell the squirrel away as well, people say it is no good. some squirrels seem to like the taste of red pepper.
