Snake Plants can sometimes attract snakes to the garden but the snake plant does not specifically attract snakes though so you can plant snake plants and not worry about snakes being attracted to them.
Just use some other things such as onion plants near the snake plants to keep the snakes away.
Some other good plants that will repel snakes from your garden and home are West Indian lemon grass, Sarpgandh and Marigold Plants.
Plant those near the Snake Plants and the snakes will stay away.
