Dig a trench

Snakes are very quite successful in getting under any fence. All they need is the slightest gap to slide under the fence and into the garden. It is recommended to bury the base of the fence in a barrier of concrete.

Now dig a trench, and make sure that it’s almost six inches deep and of the same width then fill it with concrete and just cover the base of the fence.

Make sure that the base must go about an inch or two into the concrete. If you are using a wooden fence, Don’t forget to treat the wood with sealants and also use pressure-treated wood too.

Plus, the best fencing option to prevent material damage is vinyl.

Make the use of Vinyl

As far as vinyl is concerned in snake fencing, you would find it to be excellent as a snake fence material.

The thing is that a snake fence needs to enclose your property to be successful and also to be tall enough to stop the snake from climbing.

So the surface of a vinyl privacy fence will prevent the snake from climbing up and over the property.

Well, to be more cautious, it would be better to go around the fence at night with a flashlight. At the same time, as you walk around inside the fence, mark the spot and fill the gap. If you can see even a small opening, then the snake will too.

Keep an eye on external aid

You may get success in building the best snake-proof fence possible, but the snakes are still getting into the property. How? a tree growing close to the fence may be giving them space to slide in over the structure.

just get the permission and trim the overhanging branches that can possibly help snakes sneak in. Plus, a storm drain is a common way for a snake to slip in, so don’t forget to keep them covered.


A good maintenance routine is vital to the success of any DIY fence install. You should always keep it free of fungi and termites. With a snake-proof fence, it is very important to keep an eye for new gaps in the fence.

You must not delay fixing any damage to prevent holes from appearing. The concrete that is under the fence may crack in cold weather, so you need to keep an eye on that too. Maintaining a snake-proof fence is easy, but you need to be vigilant with snake fences.
