But fencing isn't your only option for pest control against wild rabbits. Nor do you necessarily have to turn to toxic substances. In addition to fencing, wild rabbit control is possible through organic methods.
Pro-Tecs has come out with a natural repellent against wild rabbits that exploits rabbits' dislike of the smell of garlic. A concentration of garlic that, according to Pro-Tecs, is "about 1000 times stronger than garlic juice," is contained in a Pro-Tecs repellent clip. Simply attach these repellent clips to your landscaping trees, garden plants, etc. to repel rabbit pests. Each clip is said to last 6-8 months. Of course, a major selling point for a garlic-based repellent is that it's organic pest control.
One of the best "homemade" organic rabbit repellents is the soiled cat litter from a cat that has killed and eaten wild animals. Spread such cat litter, while still fresh, around your landscaping trees or garden once a week.
Another commercial rabbit repellent that can be used safely on food crops is Hinder. Hinder's active ingredients are ammonium soaps of higher fatty acids. Thiram repellent, however, is dangerous, and it can be used only on ornamental plants.
Remember, too, that some plants function as "natural pest repellents," at least in terms of saving their own hides. Many of the same plants that are relatively rabbit-proof are also relatively deer-proof. In the case of some of these plants, it's easy to see why: although natural, they're poisonous (yes, to humans, too). For this reason, deer and rabbits will generally leave alone foxglove (Digitalis) and monkshood (Aconitum), for example.
In the case of other "natural pest repellents," rabbits avoid them not because they're poisonous, but because they don't smell good -- to rabbits, at least. Aromatic herbs such as lavender (Lavendula) may send humans scurrying for their potpourri supplies, but they send rabbits just plain scurrying! And if you aren't keen on spreading your cat's litter around the yard as a repellent, at least install some catnip plants, or "catmint" (Nepeta) for puss. Rabbits don't like the smell of catnip. Nor will they like the smell of a garden frequented by a catnip-craving cat. It's also a lot of fun to see cats going crazy over their catnip!
A final consideration for rabbit pest control is the use of traps, including Havahart live-traps. Havahart's humane wire traps make for good family fun, and are especially nice to have around if you have children. Not only are they safe, but they'll afford you an opportunity to introduce your children to rabbits and other wildlife face-to-face.
