I use hair in my garden for both rabbits and deer,not sure if it works, to much other witch craft going on there also.but all combined i havent had a problem. I also throw bar soap around the paremeter,which i shred up with a manual cheeze shredder,(wife wont let me use the food procceser any more it kinda made a mess and made every thing tast like irish spring.) I do that about once a month. I also make a mixture of about 1 liters water, an egg, and 1 liter hot pepper juice.(i eat alot of jalapino so i use the juice from them, hotter the better im sure) be advised this is all witchcraft!
If all else fails i do resort to lead poisining with the trusty 12 gage shot gun.
although a snair made with picture wire is just as effective if looped in the main path of the rabbit.
Bunnys are tasty cooked in a red sauce served with a side of palenta, and some fresh greens.
please check local laws befor tryen the dinner plan though.
