4 Pacific Islands Where You Won’t See Any Snakes

Are you surprised by the number of snake species in the state you live in or in one that you’re hoping to visit? Perhaps you’d like to take a trip to a place where you won’t have to worry about coming across any slithering, venomous reptiles?

In that case, we have 4 beautiful islands in the Pacific Ocean that are completely snake-free for you to consider!

  • New Zealand: It’s pretty amazing that New Zealand does not have any snakes at all, seeing as neighboring Australia is known for many deadly snake species. The country is very strict when it comes to taking preventative measures to keep snakes out in order to protect its native animals. These reptiles aren’t allowed anywhere, including in zoos, and people are prohibited from keeping snakes as pets.
  • Kiribati: This is the only country that exists in all four hemispheres of the globe, located where the International Date Line and the equator meet. More than 5,000 years after it was settled, the land and coasts off Kiribati are still snake-free.
  • Tuvalu: Consisting of nine small islands, Tuvalu is the fourth-smallest country on Earth. While there are no snakes on land, some sea snakes can be found in its surrounding waters.
  • Nauru: You’ll find this small island country about 2,800 miles north of New Zealand. Human settlement dates back to 1,000 BC and many believe Nauru was isolated from the outside world for a long time, developing a unique culture. While the land was thought to be 100% snake-free, in recent times there have been sightings of the Brahminy blindsnake but these have been infrequent.

6 Plants That Help Keep Snakes Away From Your Yard

If you live in one of these 10 most snake-infested states and are thinking “not in my backyard!” we have some suggestions that may help!

Instead of setting traps that could harm or kill snakes (which is illegal in some states), consider a natural deterrent and make use of certain plant species to ward off unwelcome intruders.

If you’ve been burned before by a plant with false claims that it keeps snakes away, we have a list of snake-repelling plants that really work.

  • Kaffir-Limes: This is a powerful snake repellent because its citrus fragrance confuses snakes by interfering with their sense of smell. If you’re not able to plant a kaffir-lime tree, try leaving its peels and juice around your home and garden.
  • Green Chiretta: Snakes will definitely avoid this plant also known as the King of Bitters because its leaves irritate their skin and cause swelling.
  • Basil: This tasty herb, also called clove basil, emits a smell that snakes do not like. Another way to use this is to spray your surroundings with its essential oil.
  • Garlic and Onion: Snakes are not garlic lovers or fans of onions due to the sulfonic acid they both contain. Combining salt with either crushed garlic or crushed onion and sprinkling the mix around the area you want to protect is said to be effective.
  • Skunk Cabbage: This plant is popular among herbalists, who use it to treat infections, but very unpopular with snakes because it is toxic to them.
