Can't say until we see a picture as its only a brief description, remember though because of the time of the year you will be digging a lot (I know because I went to do a job today on a xmas tree farm) and the warren was under a huge holly hedge.
Its personal preference really, if you can see the holes, and net them up then I would say do it, but if you can't I would say don't. But each to their own.
All the best,
Joe
