We are entering the fall, which means lots of acorns falling along with associated foliage. Make sure you have your roof swept or blown off and, more importantly, the gutters clean. Acorns will plug up a gutter quickly, and cause water to back up in the event of a large rain storm which is quite common at this time of year. Also acorns attract squirrels, rats, and roaches, If they are on your roof they may enter your home through any opening or through the vent, that is if you dont have a CQ. So take care of your roof, it will take care of you.
