There are plants you can buy from seeds that repell bugs from Parkseed
http://www.parkseed.com/gardening/PD/1556/ to repell some insects. There is another flower they sell, that does the same thing but more effective on insects. I use a concetrated repellent that you hook to a garden hose. Then you are watering the plant and protecting it too.
