Before diving into some tips on how to keep garden snakes away from your yard and garden, let’s see if they are venomous or dangerous.

Garden snakes were considered a non-venomous species until the 2000s. Then it was discovered that their bites produced a neurotoxic venom. They are still not considered a threat to humans because the amount of venom their bites carry is very small compared to that of other venomous snakes.

Despite this, people should still avoid garden snakes, especially if they have kids or pets. The garden snakes are poisonous if eaten, and they can bite if they feel threatened. Garden snakes are considered a very aggressive species of reptiles. They can also carry salmonella and emit a musk that irritates dogs.

Snake-proof fencing

Installing snake-proof fencing might be one of the first steps to consider if you’ve noticed snakes sneaking into your yard or garden. Snake-proof fencing is usually made from vinyl or hardware cloth, and its mesh is narrow enough that snakes can’t get past it. It needs to be installed in a way that prevents snakes from climbing the fence. If you’re not sure how to handle it, you can always contact a specialist to help you install the fence the right way.

Use snake repellent

Snakes have a powerful sense of smell. Snake repellents are a very good idea to keep them out of your yard or garden.

Many commercial snake repellents are considered effective. However, you can DIY your snake repellent using natural products. One of the best products is ammonia. Snakes cannot stand its smell and won’t even dare come near it. Soak some old clothes in ammonia, put them in unsealed plastic bags, and leave the bags where you’ve previously seen snakes sneaking in. If you have a pool, pour some white vinegar around it to keep snakes away.

Don’t invite garden snakes in

Snakes will come to your yard or garden to look for water, food, or shelter. Garden snakes like to settle in grasslands, lawns, woodlands, and fields and are always near water sources. If you live in the western part of North America, it’s important to know that the snakes there are more aquatic than those in eastern North America.

Garden snakes eat small fish, slugs, earthworms, lizards, amphibians, birds, snails, and rodents.

Keep grass under control and add plants snakes don’t like

The best you can do is assess how “inviting” your yard or garden is to snakes. Keep the grass short. This will expose snakes to predators like hawks. It will also be easier for you to spot them. Avoid overwatering the grass because it will attract frogs, worms, and snakes. Plants like marigolds, wormwood, or lemongrass are natural repellents for snakes. Planting some around the house will also help.

Remove any potential hiding spots for snakes

Check the exterior of your home and the yard or garden for hiding places, cracks, or holes. If you have woodpiles around the house, you should remove them, as snakes can easily hide in between them. Bird feeders can also be dangerous as they attract rodents, and snakes will come shortly after looking for prey.

Hair is also an amazing snake repellent

Another method to keep garden snakes away from your yard or garden is to state loud and clear that people live there. What better way to do this than through their strong sense of smell? After you or someone in the house brushes their hair, save the hairs left on the hairbrush and put them around the property. It might sound strange, but snakes will smell the hair and will not enter the yard.

What should you do if you spot a garden snake in your yard or garden?

Garden snakes can be aggressive. Do not try to touch or catch them if you spot any. It’s better to have at least three feet of space between you and the snake. Otherwise, they will feel threatened. We advise you always to have a snake repellent close by. You’ll be able to spray the snake until it goes away.

Garden snakes are not harmful to humans. This is why it’s important to learn how to differentiate them from other venomous snakes, such as rattlesnakes. A garden snake bite can swell and hurt, but it’s not as dangerous as a rattlesnake bite. It’s always best to avoid any contact with a snake. If you are afraid, have no experience with snakes, don’t know what kind of snake it is, and the repellent is not efficient, you should call 911 for immediate assistance.
