Alligator Proof Fence: How to Keep a Gator Out of Your Yard

Who would like to see a big natural predator just chilling in their yard? But if you live in an area prone to visitations from alligators or crocodiles, it might not be a shocking sight for you, however unpleasant it may be. 

Then, how to make sure that your yard remains alligator-free? If you find yourself looking up “can alligators climb fences?” or  “can alligators jump?,” then you have come to the right place! Read on…

How do you Keep Alligators Out of your Yard?

There are many ways, actually, that can help you with any reptilian problem you might be facing. From removing anything that might attract alligators to your yard to setting up proper fences in the periphery, there are many easy and not-so-easy methods you can count on to deal with your troubles. Some of them are:

1. High Fences

Installing high fences with smooth surfaces is always the best option to prevent a gator or any other animal from barging into your yard. Though there is a chance that the animal can climb up the fence, taking a few extra measures can effectively solve this problem.

The higher the fence, the better security it provides. Unless it’s a chain-link fence as they have plenty of room to facilitate climbing up. So a fence that is at least 5 ft. or above, made of solid material like concrete or wood, would be your best bet against alligators. In case you can only go with wire fences, make sure they are overhanging (tilted outward at an angle of 45 degrees).

Another option is a glass fence around the property made of durable safety glass. It provides an unobstructed view if that’s what you like, and isn’t easy for animals to pass through or climb over. Though one of the cons of using this method is the constant upkeep it requires.

2. Getting Rid of Everything that Might Attract Alligators

We have been consistently encroaching upon wildlife habitats in order to accommodate the ever-increasing population. As such, it is getting more and more common to see these animals in the residential area. Especially if your house is somewhere near a lake or any other water body, there is a good chance for you to come across an alligator or other reptiles.

What you can do to minimize the chances of such a thing happening is to get rid of anything that might attract these predators. This includes any leftover food from a barbeque party or any trash that might smell like food. Any sources of water or a place where they can take shelter must be thoroughly checked and cleaned and, if possible, removed. 

When your yard doesn’t have anything to offer to them, the reptiles and other predators would naturally lose interest in trying to get into your yard.

3. Keeping the Pool Covered or in an Enclosure (Pool Cage)

Pools are really attractive to alligators. I mean, if you saw clear, refreshing, and glistening water on a hot day, you would be attracted to it too! But this can get pretty dangerous pretty quickly. So if you have a swimming pool in your yard, make sure to cover it well. But how? 

If you use the swimming pool frequently, it will be really inconvenient to cover it every day. Even if you don’t, normal pool cover works fine for small animals or insects, but for a heavy alligator, it wouldn’t make much of a difference. You can go for an automatic pool cover, which is an expensive yet reliable method. 

Or make a pool enclosure around your pool (pool cage), so it stays safe from any approaching reptiles. While having a pool enclosure does have a few drawbacks, one being the expenses incurred and the regular maintenance, it also has a number of plus points, like maintaining a constant temperature and keeping everything, like bugs or dust or alligators, out.

Do Fences Keep Out Alligators?

Gators climbing fences can be a terrible sight. I don’t want to find out if alligators climb fences or how high can an alligator jump, but I did find that out, arghhh… Nightmares for sure!

The right kind of fence does prove immensely helpful in keeping out alligators or any other unwanted visitors you might be getting. With ‘right kind,’ I mean a fence of appropriate height that is not easy to climb. The ideal fence would have these features:

  • 1.5 to 2 feet underground so alligators can’t dig below it.
  • Solid and relatively smooth, so there are not many places alligators/crocodiles can use to support their weight and climb up. Avoid chain-link fences as they are easiest for our reptile friends to climb.
  • The length of the fence should be at least 5 feet above ground.
  • They should be tilted outwards, at an angle of 45 degrees ideally, as it would make it harder to climb through. This type of fence is known as an overhanging fence.
  • The materials used for the fence can be concrete, aluminum, and wood. So the fence is sturdy enough and does not give in under the weight of the big reptile.

Can Alligators Climb a Wooden Fence?

It is very hard for alligators to climb wooden fences unless it is very rough. A smooth, polished wooden fence of proper height would be too smooth for them as they won’t have anywhere to support their weight while climbing. 

I say proper length because a short fence can still be crossed over by an alligator relying on its size and claws alone. But a fence of 5 feet or above? Not today, Gator, not today.

How Do You Scare Away an Alligator?

Here are some other ways you can use to scare away gators and keep them out of your yard. But please consider it really carefully before going through with any of this.

1. Electric Fences

One of the ways to keep alligators, crocodiles, and other animals out of your yard is to have an electric fence. Of course, this is one of the least recommended methods due to the threats it poses, to the wild animals, to any pets or children in your home, and other people living around you. 

But it is a relatively commercial method that is both easy to install and to use, and if proper measures are taken, not that harmful. 

These measures include putting up a warning sign and using a low amperage wire as it is relatively less damaging and helps keeping kids and pets away from it.

2. Alligator Repellents

This is a somewhat dubious method, but if you live alone and have a lot of reptilian visitors, there is nothing much you lose by trying it. There are no commercial alligator repellents, but over the internet, there are numerous ‘home-made’ recipes of alligator repellent.

One such method is mixing human urine with ammonia and spraying the mixture all over your property or the place where alligators are seen most frequently. It is said that the smell makes them go away, and honestly such a smell would make anyone go away, gator or not. Also, ammonia isn’t something one can handle casually. It can be dangerous.

So while not recommended and not vouched for, you can give natural alligator repellents a try.

3. Alligator Traps

Setting up an alligator trap should be the last thing on your list of solutions (yes, even below the use of urine and ammonia mixture) because it might be illegal and harmful to the animal. Not to mention, it would need another level of expertise to set up and handle these traps. 

So you can give it a try, but only after you have exhausted all the other means, and you are not taking any unnecessary risks or breaking any laws by going through with it!

4. Using Firearms

If you have a licensed weapon, you can use it to make a loud noise and scare away the gator. Making loud noise, in general, can work well, so don’t bring out the firearm unless absolutely necessary. You can kill the animal or provoke it further. There are also chances of getting injured yourself. So while using a firearm to scare a gator away might be effective, it is not advisable.


Finding a predator or big reptile in your yard isn’t a pleasant or welcome experience for most of us, and there are many ways to avoid it. Installing high and overhanging fences, getting rid of anything that might attract the gator, and keeping your pool out of reach are a few reliable methods.

There are some not-so-reliable and outright dubious methods too, but always remember that no matter what you choose to do, your safety is the most important. Try not to harm the animal. After all, they don’t actively attack us and are only looking for means to survive. 

Stay safe!
