Things You'll Need
Galvanized hardware cloth
While it rarely happens, many people are afraid of snakes falling out of trees and landing on their heads. Or, if you have a bird's nest in the tree, you may want to protect the eggs or baby birds from snakes. Whatever your reason, a few tried-and-true solutions should prevent snakes from climbing up the trees in your landscape.
Keep the area underneath trees free of plants, leaves, debris and anything else that helps hide snakes. Snakes are less likely to go to a tree where they are more exposed to their predators.
Maintain a clean landscape. Mow your grass and rake leaves frequently. Stack any wood far away from the tree. Keep your bushes trimmed and free of debris underneath.
Install a fence around your trees. It must be made from heavy galvanized hardware cloth, according to Pennsylvania State University, that is at least 36 inches wide and has 1/4-inch openings. Install it into the ground, 6 inches deep and at a 30-degree angle facing outward, away from the tree. Keep plants short to prevent snakes from crawling up the foliage.
Sprinkle a granular snake repellent, such as Snake-Away, around your trees. Follow the label's application and safety procedures.
