What method helps maintain the effectiveness of snake exclusion fences?

Slanting the fence outward at a 30-degree angle is designed to prevent snakes from climbing over the barrier. Snakes are adept climbers and can easily scale vertical surfaces. By angling the fence outward, the physical geometry creates an added challenge for snakes attempting to breach the fence. This method effectively increases the fence's ability to keep snakes contained, as it disrupts their natural climbing ability and makes it harder for them to reach the top and get over to the other side. This design is especially beneficial in settings where the goal is to protect certain areas, such as gardens or livestock enclosures, from snake intrusions.
