Having fought several battles with raccoons myself (including once in my attic, when neither of us were expecting it), I can say that the best solution is to have dogs in the neighborhood which are big enough to handle a raccoon. Or, if that doesn't work, a trail of marshmallows to lead them into the raccoon trap (they are suckers for that). I hire pros to do the latter.
