I would be more concerned with hitchhikers in the soil, if there is any, for any plant being brought indoors for winter.
Actually, with some of my amaryllis, since I know they have been enjoying the sun all summer long to early Fall, I just cut off the leaves when I bring them in. To make them rest the entire winter. It will just depend if you intend to see blooms indoors. That is not my goal anymore with my amaryllis so, I just let them follow Spring cycle blooming.
