Is Lemongrass an Effective Snake Repeller?

Snakes are fascinating creatures that are found in various parts of the world, from deserts to forests, and even in urban areas. However, they can also pose a risk to humans and pets, especially when they are venomous. Therefore, it is important to take measures to keep snakes away from homes and gardens. One such measure is the use of natural repellents, such as lemongrass. This guide aims to provide an overview of snakes, the properties and uses of lemongrass, and other natural snake repellents and deterrents, as well as tips for using them safely and effectively.

Understanding Snakes

Overview of Snake Species

There are over 3,000 species of snakes, of which approximately 600 are venomous. Venomous snakes can be found in different parts of the world, including North and South America, Africa, Asia, and Australia. Some of the most common venomous snakes include:

  1. Copperhead
  2. Rattlesnake
  3. Coral snake
  4. Cottonmouth

Non-venomous snakes are generally less dangerous to humans, but can still be a nuisance, especially if they take up residence in homes or gardens. Some common non-venomous snakes include:

  1. Garter snake
  2. Rat snake
  3. King snake
  4. Green snake

Snake Habitat Preferences

Snakes have specific habitat preferences, which can vary depending on the species. Some common factors that attract snakes to homes and gardens include:

  1. Prey availability: Snakes are attracted to areas where they can find food, such as rodents, insects, and small mammals.
  2. Shelter: Snakes require shelter to hide from predators and to regulate their body temperature. This can include areas under rocks, logs, and debris, as well as inside walls, attics, and basements.
  3. Water sources: Snakes need water to survive and can be attracted to areas with standing water, such as ponds, birdbaths, and swimming pools.

Dangers and Benefits of Snakes

  1. Snake bites: Venomous snakes can pose a danger to humans and pets, causing pain, swelling, and in some cases, death. It is important to seek medical attention immediately if bitten by a venomous snake.
  2. Ecosystem balance: Snakes play an important role in the ecosystem, helping to control rodent and insect populations, as well as serving as prey for larger predators.

Lemongrass: Properties and Uses

Description of Lemongrass

Lemongrass (Cymbopogon citratus) is a tropical plant that is commonly used in Asian cuisine, as well as in traditional medicine. It has a lemony scent and flavor, and is often used in teas, soups, and curries. Lemongrass is also used in perfumes, soaps, and cosmetics.

Traditional and Medicinal Uses

Lemongrass has been used for centuries in traditional medicine to treat a variety of ailments, including:

  1. Digestive problems
  2. Respiratory issues
  3. Headaches
  4. Fever
  5. Arthritis

Lemongrass has also been found to have anti-inflammatory and antimicrobial properties, making it a potentially useful ingredient in skin care products.

Insect-Repellent Properties

  1. Chemical Composition: Lemongrass contains a compound called citronellal, which has insect-repellent properties.
  2. Effectiveness against Mosquitoes and other Insects: Several studies have found that lemongrass oil can be effective in repelling mosquitoes and other insects. One study conducted in Thailand found that a lotion containing lemongrass oil provided up to 98.4% protection against mosquitoes for up to two hours. Another study found that lemongrass oil was effective in repelling ticks, which can carry diseases such as Lyme disease.

Lemongrass and Snake Repellent Claims

Origin of Lemongrass as a Snake Repellent Claim

The use of lemongrass as a snake repellent has gained popularity in recent years, with many people claiming that planting lemongrass around homes and gardens can help keep snakes away. The origin of this claim is unclear, but it may have originated in traditional medicine practices, where lemongrass was used to repel insects and other pests.

Anecdotal Evidence

There are many anecdotal reports of people successfully using lemongrass to repel snakes. Some people claim that planting lemongrass around their homes has helped keep snakes away, while others have reported that spraying lemongrass oil around their property has been effective.

Scientific Research on Lemongrass and Snakes

  1. Studies on Snake Behavior and Olfactory Senses: Snakes rely heavily on their sense of smell to navigate their environment and locate prey. Several studies have found that snakes are sensitive to certain odors, including some essential oils. However, it is unclear whether lemongrass has a strong enough odor to repel snakes.
  2. Research on Lemongrass Oil and Snake Repellent Properties: A few studies have investigated the use of lemongrass oil as a snake repellent. One study conducted in India found that a combination of lemongrass oil and cedarwood oil was effective in repelling snakes from residential areas. However, the study did not investigate the effectiveness of lemongrass oil on its own. Another study conducted in the United States found that lemongrass oil was not effective in repelling snakes.
  3. Limitations and Gaps in Current Research: The studies conducted so far have been limited in scope and have produced mixed results. Further research is needed to determine whether lemongrass is an effective snake repellent and to identify the most effective methods of using it.

Other Natural Snake Repellents and Deterrents

Essential Oils

  1. Clove Oil: Clove oil has been found to repel snakes in some studies. One study conducted in India found that a combination of clove oil and cinnamon oil was effective in repelling snakes from residential areas.
  2. Cinnamon Oil: Cinnamon oil has also been found to have snake-repellent properties.

Plants with Snake-Repellent Properties

  1. Marigolds: Marigolds have a strong odor that is unpleasant to snakes and can help repel them from gardens.
  2. Garlic: Garlic contains sulfur compounds that are offensive to snakes and can help repel them from gardens.
  3. Mother-in-Law’s Tongue: This plant, also known as snake plant, is believed to repel snakes due to its strong scent.

Habitat Modification and Physical Barriers

  1. Clearing Debris and Clutter: Snakes are attracted to areas with clutter and debris, as they provide hiding places and shelter. Clearing these areas can help make the environment less attractive to snakes.
  2. Sealing Entry Points: Snakes can enter homes and gardens through small cracks and openings. Sealing these entry points can help keep snakes out.
  3. Installing Snake-Proof Fencing: Snake-proof fencing can be effective in keeping snakes out of gardens and other areas. The fencing should be buried at least six inches deep and should be made of materials that snakes cannot climb.

Tips for Using Lemongrass and Other Natural Repellents

Proper Planting and Spacing

When using plants with snake-repellent properties, it is important to plant them in the right location and to space them properly. Some tips to keep in mind include:

  1. Plant marigolds and other snake-repellent plants around the perimeter of the garden or home.
  2. Plant lemongrass in well-draining soil and in an area with plenty of sunlight.
  3. Space plants at least one foot apart to allow for adequate growth and to ensure that the scent is spread evenly.

Using Essential Oils Safely and Effectively

When using essential oils as a snake repellent, it is important to do so safely and effectively. Some tips to keep in mind include:

  1. Dilute the oil with a carrier oil, such as coconut oil or almond oil, before applying it to the skin or spraying it around the property.
  2. Test a small area of skin before applying the oil to the entire body.
  3. Reapply the oil every few hours to ensure effectiveness.

Regular Maintenance and Inspection

To ensure that natural snake repellents and deterrents are effective, it is important to regularly maintain and inspect the garden or property. Some tips to keep in mind include:

  1. Remove any debris or clutter from the garden or property.
  2. Seal any cracks or openings in walls or foundations.
  3. Inspect the property regularly for signs of snake activity, such as shed skin or snake tracks.


Lemongrass and other natural snake repellents can be effective in keeping snakes away from homes and gardens. However, it is important to use them in conjunction with other snake control strategies, such as habitat modification and physical barriers. It is also important to remember the important role that snakes play in the ecosystem and to consider non-lethal methods of control whenever possible. By taking a multi-faceted approach to snake control, it is possible to create a safe and snake-free environment for humans and pets alike.
