Although the average rabbit only lives to be about a 1 1/2 years old, it can raise up to 6 litters in that short time, with about 5 rabbits per litter, meaning that once you get rid of one rabbit, you certainly haven't got rid of them all. Rabbits are active all year long and like to live in areas dominated by humans, since there are fewer predators in those areas. Rabbit holes are not only a nuisance, they can be dangerous, spraining or breaking the ankle of anyone who manages to wander into one.
Identify the damage as rabbit holes, either by observing rabbits coming and going from them or looking for other signs, like waste. Rabbits prefer pine tree farms, the edges of fields, orchards and other human-dominated areas because there are fewer predators.
Get rid of the rabbits by either repelling them with a commercial repellent, urine, fencing or live trapping. There are no chemicals registered to repel rabbits.
Remove any brush piles or other debris to prevent rabbits from preferring your landscape over others. Mow the grass and remove any potential cover for the rabbits so they don't feel safe in your yard.
Locate the rabbit holes and fill them in with dirt, rocks, gravel, sand or concrete. Concrete is the best method and will keep rabbits from reusing the hole, however, it will also render the land useless. Filling in the whole with some gravel and then dirt should keep it usable and rabbit-free.
Plant a tree, shrub or other plant in the hole after you fill it in to discourage rabbits from coming back.
