The 6 Best Snake Repellent – How to Keep Snakes Away 2021

There is likely to be a number of reasons why you might want to repel snakes from your garden or property. First and foremost, safety is obviously an important factor, and if you live in an area where poisonous snakes are around then investing in a quality snake repellent is a must have product. Even non-poisonous snakes can be a nuisance, potentially posing a threat to your pets, meaning you want something to keep them at bay.

Here we review a variety of the best snake repellents available on the market, including chemical based, natural and sound based repellents, that will do just the trick without causing any permanent damage to the snakes in question. Read on to find out more…

Best Chemical-Based Snake Repellents

Chemical based snake repellents contain either Naphthalene or Sulfur, and can sometimes contain both. Snake repellents that use these chemicals rely on the properties of these chemicals which affect a snakes sense of smell, with the intention of triggering the snake to be repelled from that area.

While effective, there are some drawbacks of using chemical based repellents as they can be damaging to plants and can be lethal if consumed by a human. This means you need to take extra care if your children are going to be playing outside in areas where you have used these snake repellents. In fact, if you have kids or pets, you may wish to select sound based repellents instead.
