Answer
Hi Nicole, There are several good repellent sprays on the market, check with your local independent garden center for one approved for use in your area.  Some mulches tend to repel them...pine needles and lava rock.   
I've also had success spraying the ground with a product called Tanglefoot.  It's a sticky substance used to prevent birds from roosting and insects from crawling up tree trunks. Jim
