you can put dog hair and human hair around your plants too along with the pepper but you will have to replace them from time to time as the small fades....and the moth balls might work too but I have never used them
There is actually spray you can buy at gardening stores. Simply spray it on the plants and it discourages the rabbits. There are also various plants you can plant in the area that will keep rabbits away. Marigolds will deter rabbits.
