These rabbits really do need to be caught. They will keep reproducing and many of them are going to come to bad ends at the hands of a predator, by being hit by a car or by being targeted by a mean person. The original pair were probably thrown out by their owner. It unfortunately happens a lot.
There are 2 methods to try to catch them. You can either do it personally, a single person or a small group is better. Lure them to you with apple, banana, cilantro. Try to close in on them, but never chase them, and if you can corral them up against a fence or building, it won’t be so easy for them to run away. Don’t expect to be able to get them on the first try. It does happen, but it can also take a while. Make sure that you have a carrier or small cage at hand, because rabbits are hard to hold onto and they will struggle. If you drop one, not only do you risk injury, but it may never let you get near it again. You can also try throwing a blanket over a rabbit to slow it down or stop it in order for you to firmly grasp it.
Here is one article on catching rabbits: http://www.columbusrabbit.org/strays.php
You can use a humane trap, but it has to be monitored at all times. If the rabbit goes in, it shouldn’t stay there long. It is vulnerable to predators scaring it or getting at it, plus they can become so frightened that they injure themselves by crashing around inside the trap. You would bait it with apple, pear, banana, etc. You are also liable to catch possums or raccoons in the trap.
