I have a snail infestation. How do I manage them in a human way, and what are the risks for my fish?

They came as eggs with plants I bought months ago. I honestly don't have a problem with them but over the week their population EXPLODED. They are everywhere and covering almost the entire floor. I understand I may need to get rid of them but they are still are live beings and I dont want to be inhuman. How do I get rid of them?
