Those Wascaly Wabbits!!

I have 5 flower gardens in my front yard and two perrenial gardens in my backyard. Four of the front gardens have tulips and other spring time bulbs in them. It is not unusual to see rabbits running around our yard, and even our neighborhood. And as I'm sure you can guess, rabbits + tulips = bad news. Well, I have never been a real pesticide oerson, rather I prefer more natural mathods of control. Up until now the rabbits have maybe eaten the tips of of my tulip leaves...annoying yes, but not terrible. However, 2 days ago after coming home from taking Wynn to school, I lost it! I looked at my garden, and where there were 9 grape hyacinth plants growing and flowering beautifully, there were now 9 green little stubs sticking out of the dirt!!!! I was livid, that's it...now I mean war! Many people have mentioned putting moth balls on their gardens to control rabbits so I thought I'd give it a try. Conveniently, I was already making a trip to my local Walmart so while I was there I picked up the biggest box of moth balls I could find. It rained all day yesterday so I figured I'd spread them on the flowers today as the rain had stopped. First I went onto the 'net to figure out how exactly to apply these (whole, crush, sprinkle...) and that's when I read something that I hadn't realized or "put 2 and 2 together" so to say. Moth balls are very toxic just google "moth balls toxic" and you will see what I mean. Well, I defenitly don't want them in my house or even on my flowers where my children can get at them. I'm returning them ASAP and going to get some other rabbit deterrent. In my searching I read many ways people suggest of controlling rabbits from fencing, trap & release, pepper spray, and motion detectors. On one site I read, someone suggested planting chives around the flowers and someone else mentioned placeing branches from their Russian Sage bush around the flowers. These last two I prefer and may try. Have any of you had problems with rabbits eating your gardens? If so, what works for you?
