If you're in the USA it won't do you any good--the nets were used in the UK and Europe because the rabbits there den underground in warrens. The rabbits in the USA don't den at all in colonies, only a mother rabbit may den with young, and it's only for a few weeks at most.

If you're in Europe or the UK, contact a ferret bulletin board and you'll find someone with hunting ferrets who most likely uses them.

Be aware that ferrets sent in after rabbits often make a kill underground and have to be dug out with shovels. A very careful proceedure since you don't want to injure the ferret in the process.
