Can You Use Snake Repellent When It Rains? Or Should Wait?

Can You Use Snake Repellent When It RainsSnakes keep appearing on your property as if there’s an open invitation for them even after you treat the area with an effective snake repellent. One of the common reasons is that the rain washes away the repellent substance. That makes you wonder, can you use snake repellent when it rains? It even makes doubt the product altogether.

Of course, you can use snake repellent when it rains. You just need to read the label before purchasing to check a small thing called ‘rain-resistant formula’. This small part in the description prevents your product from getting wasted during rainfall. Not to mention, it will also not let your money go to waste.

In the post below, you will find those snake repellents that you can use during rainy days too. Their sterling ratings and glowing reviews assure that their efficacy remains intact even after rainfall. So, let’s dive in.

Can You Use Snake Repellent When It Rains?

It’s another way of asking whether snake repellent is waterproof or not. That depends on the repellent product you are using. The simple answer is, yes, you can use snake repellent when it rains.

You will find several commercial products in the market that are rain-resistant, rainproof or waterproof. That means they will retain their effectiveness for 2-3 weeks to 2-3 months, depending on the concentration of the product. The rain will not wash it away.

On the other hand, many repellents do not contain a rain-resistant formula and will be destroyed by rain. Long story short, both your money and product will go to waste.

Which Snake Repellent Can You Use in Rain?

The above discussion brings us to the next most logical question: which snake repellents are rainproof or rain-resistant? I have shortlisted the names of commercial snake repellents that have a rain-resistant formula. Therefore, you can safely apply them in rainfall.

  1. Dr T’s Snake-A-Way

The first on my list is Snake-A-Way. It’s a mixture of dry granules that you can easily apply around your home, garage, cabin, campsite or any other outdoor space. According to the product label, its effectiveness can last up to 3 months.

The rain will not dilute the product. However, you shouldn’t rely on that entirely because it will ditch you in heavy rain. Meaning, one torrential rain will wash the product away.

  1. Ortho Snake-B-Gon

Another option is Ortho Snake-B-Gon. This one also embodies rain-resistant performance. Again, it’s in granular form with rain-resistant formula. One application can remain effective for approximately 30 days if you apply it according to the given directions.  A big plus is that its non-toxic formula is safe to use around your little ones and pets.

However, you may need to re-apply it after a heavy downpour.

  1. Victor’s Snake Away

Victor’s Snake Away repellent also claims to have a rain-resistant formula. That means you can use it in normal rainfall. However, we cannot say the same when it’s raining cats and dogs. So, you might have to re-treat the area after the downpour stops.

Otherwise, the EPA-approved repellent is highly effective and lasts around 2 to 3 months.

  1. Nature’s Mace Snake Repellent

The reviews and customer ratings of this product are pretty impressive, so I had to add it to my list. Plus, my neighbour also uses it consistently and is happy with it. The product uses natural ingredients with an all-season-long and rain-resistant formula. Therefore, you can confidently spray it in summer, spring, fall, winter, during irrigation or rainfall. Some customers reviewed that the product remained in place even after heavy rain.

A big plus is that pesky bugs also leave the treated area.

  1. Exterminator’s Choice – Snake Defense

As you can guess from the title, professional exterminators have made this repellent. It has an oil-based formula having natural essential oils as active ingredients. So yeah, it’s totally environment-friendly and safe to use around your kiddos and beloved pets.

Like many others on the list, you can use it when it rains to keep annoying garter snakes, copperheads, rattlesnakes and many other species of snakes off your premises. Since its sustaining capacity against torrential rain is unconfirmed, I suggest you re-apply it after an intense downpour.

  1. Ultrasonic Snake Repellents

Ultrasonic repellers are devices that emit high-pitched noises of specific frequencies that are only audible to snakes. Many solar-powered ultrasonic repellers are waterproof. So, they work fine during rainy days too.

Note: No matter which snake repellent item you choose, remember that it’s one of the means to keep snakes away. It shouldn’t be your only line of defence against snakes. You must apply other methods alongside repellents to have a snake-free house or yard.


Snake repellents are hot-selling products for people living in snake-active areas. They fail you badly during rainy days because you usually don’t confirm whether they can remain effective in rainfall or not. You can confidently use only that snake repellent during rain which contains a waterproof or rain-resistant formula. You should reconfirm to ensure the product will not go down the drain with heavy rainfall. I jotted down the names of some highly popular and effective snake repellents in the article above. They can sustain average rainfall. Hence, you can use them when it rains.
