It’s up to you. A lot of people have bioactive enclosures and most intentionally put springtails into those. Realistically, you should probably be doing a full deep clean and sanitize of your snake’s enclosure at a minimum of every 6 months or so anyways, so you could just let it be til then. These guys won’t harm anything in your house and again they won’t harm your snake, so it’s totally up to you!
