You can dip your plants. One chemical that I've seen lately is potassium permanganate (KMnO4). I think it kills both snails and their eggs. You could probably house the plants in a QT tank with botiid loaches, that would get rid of a lot of your snails.
I've never dipped my plants, as I like the little bugs that come in. I've only ever gotten Physa snails before, and a lot of copepods, but I like both, so it's ok.
