If the soil surrounding the rose is a breeding ground for the pest, you should use a pesticide soil drench to break the breeding cycle. I can't recommend any particular brand, but if you ask for a pesticide soil drench at a nursery, they'll give you more information, I'm sure.
If I were transplanting a rose because I suspected soil damage, I'd wait until the rose was dormant and then treat it like a bare-root rose. Shake off as much soil as possible and then soak the roots to dislodge any remaining soil before you plant it in the new location.
