3 Ways: Mothballs for Snake Repellent

The thought of encountering snakes in your yard or garden can be unsettling, but fear not! Mothballs, those small, round pellets often associated with warding off moths, can also serve as an effective snake repellent. Here’s how you can utilize mothballs to keep snakes at bay and create a safer environment for your family and pets.
Understanding the Snake Problem

Snakes are an essential part of the ecosystem, helping control rodent populations and maintaining ecological balance. However, when they invade residential areas, they can become a nuisance and even a safety concern. While most snakes are non-venomous and shy away from human contact, some species can be dangerous. It’s crucial to find ways to deter snakes from entering our living spaces without causing them harm.
The Power of Mothballs

Mothballs are small, pungent pellets made from various chemicals, primarily naphthalene or paradichlorobenzene. These chemicals have a strong, distinctive odor that is highly effective in repelling snakes and other pests. When placed strategically, mothballs can create an unpleasant environment for snakes, discouraging them from entering or staying in the area.
Method 1: Direct Placement
One of the simplest ways to use mothballs as a snake repellent is by placing them directly in areas where snakes are likely to hide or enter. Here’s a step-by-step guide:
Identify Potential Entry Points: Snakes often enter yards through crevices, gaps in fences, or areas with dense vegetation. Survey your property to locate these potential entry points.
Prepare the Mothballs: Open a new package of mothballs and ensure they are fresh and potent. Old mothballs may have lost their effectiveness.
Place the Mothballs:
- Under Decks and Porches: Snakes often seek shelter under decks and porches. Place a few mothballs in these areas, ensuring they are out of reach of children and pets.
- Around the Perimeter: Create a barrier by placing mothballs along the outer edges of your yard, especially near fences or walls. This can deter snakes from entering your property.
- In Snake-Prone Areas: If you’ve noticed snake activity in specific areas, such as a garden shed or a pile of firewood, place mothballs in these locations to create an uninviting environment.
Refresh Regularly: Mothballs lose their potency over time, so it’s important to replace them every few months or sooner if you notice signs of snake activity.
Method 2: Mothball Bags
Another effective way to use mothballs is by creating sachets or bags filled with them. This method allows for a more controlled release of the scent and can be particularly useful in enclosed spaces.
Gather Materials: You’ll need small fabric bags (like muslin or cotton bags), mothballs, and a needle and thread.
Fill the Bags: Place a few mothballs in each bag, ensuring they are securely closed. You can tie a knot or stitch the opening shut.
Hang or Place the Bags:
- Hang them Strategically: Attach the bags to hooks or nails in areas where snakes are likely to hide, such as under eaves or in crawl spaces.
- Place in Storage Areas: If you have a shed or garage where you store garden tools or equipment, placing mothball bags inside can deter snakes from taking up residence.
- Use in Birdhouses: Snakes sometimes take advantage of birdhouses. Placing a mothball bag inside can discourage them without harming the birds.
Method 3: Mothball Spray
For a more versatile approach, you can create a mothball spray that can be applied to various surfaces. This method allows for targeted application and can be useful for treating larger areas.
Prepare the Spray: Mix a small amount of mothballs (crushed or grated) with water in a spray bottle. Ensure the mothballs are completely dissolved.
Application Tips:
- Spray Entry Points: Apply the spray around doors, windows, and other potential entry points to create an odor barrier.
- Treat Snake Trails: If you’ve noticed snake trails in your yard, spraying along these paths can deter snakes from returning.
- Refresh Regularly: Reapply the spray every few weeks or after rainfall to maintain its effectiveness.
Safety Precautions
While mothballs are an effective snake repellent, it’s important to use them safely:
- Keep Out of Reach: Mothballs should be kept away from children and pets, as ingestion can be harmful.
- Avoid Overuse: While effective, mothballs should be used judiciously. Excessive use can lead to environmental concerns and may not be necessary for long-term snake control.
- Follow Instructions: Always read and follow the instructions on the mothball package, as some products may have specific usage guidelines.
Snake Repellent Alternatives
While mothballs are a popular choice, there are other natural and chemical repellents available:
- Natural Repellents: Essential oils like cinnamon, clove, and peppermint are known to repel snakes. Creating a spray with these oils can be an eco-friendly alternative.
- Chemical Repellents: Commercial snake repellents are available, often containing sulfur or naphthalene. These products can be effective but should be used with caution and according to the manufacturer’s instructions.
Expert Insight: Balancing Snake Control and Wildlife Conservation

“It’s important to strike a balance when managing snake populations,” says Dr. Sarah Thompson, a wildlife biologist. “While snakes can be a nuisance, they also play a vital role in our ecosystems. Using repellents like mothballs can be an effective way to deter snakes from entering residential areas without causing harm. It’s a win-win situation, allowing us to coexist peacefully with these fascinating creatures.”
Final Thoughts
Mothballs, with their strong odor, offer a simple and effective solution for snake repellent. By using these methods and being mindful of safety precautions, you can create a snake-free environment while respecting the role of snakes in the natural world. Remember, a little creativity and strategic placement can go a long way in keeping your yard safe and enjoyable for all.
