Mothballs for Snakes: How Effective Are They?

It’s no secret that snakes can be a significant nuisance. They tend to show up uninvited and can be challenging to eliminate. That’s why many people turn to mothballs to repel snakes. But are moth balls actually effective at keeping snakes away? Let’s take a closer look.

Mothballs are small balls of chemical pesticide that release a strong, foul-smelling odor when air exposure. Naphthalene or paradichlorobenzene is the active ingredient in mothballs, which are toxic to snakes. 

In theory, mothballs should be an effective way to keep snakes away from your home. However, there are a few problems with this approach. 

  • The mothballs’ fumes can harm humans and pets if inhaled in large quantities.
  • Mothballs can also be toxic if swallowed, so you’ll need to be careful about where you place them if you have young children or pets in your home.
  • Mothballs are not registered as pesticides with the EPA, and their use is regulated by the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). This means that mothballs can only be used in specific ways and for particular purposes described on the product label.
  • Snake populations tend to be relatively small in areas where mothballs are regularly used, so the repellent effect of mothballs may be simply not strong enough to make a noticeable difference. 

How Mothballs for snakes Works

Mothballs are designed to kill moths, larvae, and eggs by releasing toxic chemicals into the air. The main ingredient in mothballs is naphthalene, a white, crystalline substance with a strong odor. When exposed to air, naphthalene becomes a gas that can be inhaled. This gas is what kills moths and their larvae. 

The Use of Mothballs to Repel Snakes

Mothballs are sometimes used to repel snakes because they produce a strong odor that snakes do not like. Because snakes use their sense of smell to find food and shelter, a spicy scent can dissuade them from an area.

However, mothballs are not specifically designed to repel snakes, so they may not be as effective as other snake repellents. Snakes are attracted to the pungent smell of mothballs, making them more likely to take up residence in your yard.

Are moth balls for snakes illegal?

Did you know that moth balls are illegal for snake repellents?

That’s right – the Environmental Protection Agency (EPA) has banned the use of mothballs for this purpose due to the harmful effects they can have on the environment.

While mothballs may be effective at keeping snakes away, they also release toxic chemicals into the air that can harm human health.

In addition, moth balls can contaminate soil and water resources, making them a potential environmental hazard.

If you’re looking for a safe and effective way to keep snakes away, many other products (See Here) on the market are specifically designed for this purpose.

There are many commercial snake repellents available that are designed specifically to repel snakes. These products often contain cinnamon oil or sulfur, which snakes do not like.

Snake repellents can be applied around the perimeter of your home or property to help keep snakes away.

Here are three practical ways to keep snakes away:

1) Use a Snake Repellent

Several different snake repellents on the market can be used to effectively keep snakes away from your home.

Some of the most popular snake repellents use strong scents or ultrasonic waves to discourage snakes from entering an area. For best results, try using a combination of different snake repellents around your property. 

2) Keep Your Yard Clean

One of the best ways to keep snakes out of your house is to make sure they don’t have any reason to enter your property in the first place.

Snakes are attracted to cluttered or overgrown areas, so keeping your yard clean and well-maintained is a great way to deter them.

Rem trims any overgrown bushes, remove debris, and keep your grass cut short. 

3) Remove Their Food Source

Remove Their Food Source

Another way to discourage snakes from entering your property is by removing their food source. If smaller animals are on your property, such as rodents or rabbits, snakes will be attracted to the area in search of a meal.

To avoid this, seal up any holes or cracks in your home that might serve as an entry point for rodents. You should also consider investing in a good set of rat traps. 

When to call a pest control service?

Sometimes, you may need to call a pest control service to deal with a snake problem. Here are three signs that it’s time to bring in professionals.

You Have More Than One Snake

You Have More Than One Snake

While one snake may not pose much of a threat, having more than one on your property can cause concern. If you start seeing multiple snakes, it’s likely that they’re living near each other and could potentially breed.

This can cause your snake problem to spiral out of control very quickly. By calling a pest control service, you can nip the issue before it gets too big as soon as you spot more than one snake.

The Snake is Inaccessible

Some snakes hide in hard-to-reach places, such as inside walls or attics. If you see a snake in an inaccessible area, it’s best to call a professional rather than try to remove it yourself.

Pest control specialists have the training and equipment to safely and effectively remove snakes from difficult-to-reach areas. 

You’re Unsure of the Snake’s Species

You're Unsure of the Snake's Species

Not all snakes are created equal some are harmless while others are venomous.

Identifying a snake yourself can be dangerous if you’re not an expert, so it’s always best to err on the side of caution and call a pest control service if you’re unsure what type of snake you’re dealing with.

Pest control specialists can quickly and accurately identify the snake species and take appropriate action based on that information.

Snake Removal in my area: Who to call? 

If you reside in an area with many snakes, it’s essential to know who to call for snake removal.

In many cases, the best option is to contact your local animal control. They will have the experience and knowledge necessary to safely remove the snake from your property.

If you have a particularly large or dangerous snake, you may need to call a professional wildlife removal service. These services usually charge a fee, but they will have the equipment and expertise necessary to safely remove the snake.

In either case, ensuring the snake is removed from your property as soon as possible is essential. Snakes can be dangerous, and they can also damage your property if they’re left unchecked. You can ensure your home is safe from snakes by taking proactive measures.


Using mothballs as a snake repellent is not the most effective solution. While the chemicals in mothballs may be toxic to snakes, they can also be harmful to humans and animals if inhaled in large quantities.

Snake populations tend to be small in areas where mothballs are regularly used, so the repellent effect of mothballs may be simply not strong enough to make a noticeable difference.

If you’re looking for a more effective way to keep snakes away from your home, you may consider using a physical barrier such as a fence instead.
