How can I get rid of the...

Although snakes may be bothersome, they do help to control other garden problems such as caterpillars and slow-moving insects. If you still want to eliminate them from your garden, get rid of all possible hiding places, including hay, mulch, black plastic, and the like. Keeping the nearby grass and weedy areas trimmed is also helpful. Other remedies include sprinkling dried sulfur (available at farm and garden stores) or limestone around the area to be protected. Onions are also thought to repel snakes.
