Scare Tactic

I have a neighbor who refuses to use pest control chemicals for her garden. She does not think it's healthy.  She uses alternative pest controls, and she promised to show me how to make them just by using some stuff I already have at home.  I am more interested in getting rid of the rabbits who roam my backyard as if it's their own territory.  My dog tries to scare them away, but his constant barking is annoying the neighbors.  Not good when you want to keep peace and harmony in your neighborhood.
