The only effective way to deal with rabbits is to fence them out. I have discovered that they will go right through chain link and can go through the openings in a 4 X 1 1/2 inch mesh.
I've got 7 foot tall game fence around my garden, for the deer. Then a 4 foot tall poultry net is 2 1/2 feet up the fence and 1 1/2 feet laying on the ground as a skirting to prevent digging in. That stops the rabbits and the deer, but I still must cover the seedlings or the quail eat all the lettuce and spinach as it emerges. Also, the gate must fit very tight or the rabbits will squeeze around the edge of the gate.
