The Best Snake Repellent Options


Some people handle sudden and unexpected encounters with serpents surprisingly well, while others not so much. Most human snakebites happen when people tamper with snakes to move them. Even if you come across a deceased snake, it can be frightening. In each case, it’s better to avoid these scenarios in the first place. That’s where snake repellent can help.

Snake repellents, combined with proper landscape maintenance, help people and snakes avoid unwanted encounters. Repellents use scent or sound to create an uncomfortable environment for snakes, and humans can’t tell if the area has been treated. But not all snake repellents are equal. If you’re looking to avoid snake encounters this season, read our suggestions to find the best snake repellent for your lawns or garden.

Before You Buy a Snake Repellent

Consider the hazards of snake repellents before buying. Some scent-based snake repellents have ingredients that are harmful to people or pets that come into direct contact with them. They may also have a potent aroma, making it unpleasant to be in the area.

Be careful when applying snake repellent for the first time because if snakes are in the vicinity, they may become more agitated and aggressive. Keep people and pets away during and immediately after treatment to avoid encounters with snakes.

Features to Look for in a Snake Repellent

Snake repellents use either scent or ultrasonic soundwaves that irritate or confuse the senses to keep snakes out of the area. Some products are best suited for small spaces or indoor use, while others are best for large outdoor areas. When shopping for a snake repellent, consider these features to determine which product will best suit the location.


Most snake repellents are scent-based, which poses a challenge for scent-loving snakes. In addition to smelling through their nostrils like other creatures do, snakes employ a sensitive pair of organs in the roof of their mouth, called the vomeronasal or Jacobson’s organ, to do detailed sniffing. They flick the air with their tongues and pull in scent particles that primarily help them track their prey. Odors of scent-based repellents irritate or confuse snakes.

Odor strength, not stinkiness, is the key to success. Some of the best products use pleasant fragrances like cinnamon and clove. The best scent-based snake repellents have higher concentrations of active ingredients, so they work better and last longer.


Even someone with the worst snake phobia would get tired of reapplying repellent every day. Plus, longer-lasting products are easier on the budget. The best snake repellents stay effective for up to a month, although heavy rain will make even the best products dissipate faster. Long-lasting repellency comes from higher concentrations of active ingredients and granular formulations resistant to rain.

There are times and places when liquid snake repellent is more user-friendly than long-lasting granular formulas. In those instances, go for the more potent, high-concentration formula. Again, a stronger scent is more effective from the outset and lasts longer.


The most popular snake repellents are scent- or odor-based because they can be applied almost anywhere. These products use various natural essential oils or chemical compounds that produce strong scents to overwhelm the snake’s sense of smell, decreasing its ability to detect prey, and may also be a physical irritant. Uncomfortable and confused snakes simply move out of the treated area. Odor-based repellents are available for indoor and outdoor use.

Another snake repellent option is ultrasonic sound. Electric devices that plug into household electrical sockets emit noise outside the human hearing range that snakes can’t stand. They eventually leave the area because of the discomfort. These products have a limited range making them most appropriate for indoor use.

  • Odor: The best scent-based snake repellents have a strong but pleasant smell and are long-lasting and easy to apply.
  • Ultrasonic frequency: The best ultrasonic snake repellers cover a large-sized room and produce no audible noise to human ears.

The Best Snake Repellent: Tips For Keeping The Snakes Away From Your Yard


Other Pro Tips For Keeping The Snakes Away From Your Yard

Snakes are an essential part of the natural world as they help to keep pest populations in check. But most people would rather not be surprised to find them in the backyard or inside the house. Although venomous snake bites are quite rare, they are very serious and sometimes deadly when they do occur. Even a nonvenomous snakebite is painful and can lead to infection or illness. If there is a concern about snakes on the property, the first course of action is to eliminate what attracts them.

Like other predators, snakes spend most of their lives either pursuing their next meal or resting. Places that provide opportunities for food or a sheltered resting place are the places that snakes find appealing. The most effective way to minimize the risk of snake encounters is to eliminate the habitat that supports snake prey like small rodents and large insects, and areas that snakes can use for shelter.

Tallgrass, shrubs with dense foliage to the ground, piles of leaves and sticks, and fallen fruits and nuts make a perfect home for mice and rats. Snakes will come around to find them. A water source such as a decorative landscape pond, or even a low spot that holds water after rain, seals the deal. This is the perfect backyard habitat for snakes.

Practice proper yard maintenance to eliminate shelter and food sources for snakes and rodents. Mow regularly, remove landscape debris promptly, and clean up fallen fruit and nuts beneath trees. Feed pets indoors, limit bird feeding, and cleanup pet and bird food spills. Don’t keep a year-round firewood pile that can also shelter snakes. Burn up all firewood before snakes become active in spring. Consider eliminating decorative landscape ponds and bird nest boxes, both of which can attract snakes. After removing snake habitat, snake repellent can help keep them away.

  • Snake repellents can drive away snakes that are still in the area after cleaning up the landscape.
  • Snake repellents keep snakes out by creating an unpleasant, unwelcome environment for them.
  • It’s nice to get peace of mind, knowing that your home is now a snake-free zone after a few simple changes in habitat and a straightforward application of snake repellent.
