How to Repel Snakes with Irish Spring Soap

Snakes are a common concern for residents in areas with snake populations. While there are various methods for repelling snakes, one popular method is using Irish Spring soap. In this guide, we will cover the biology and behavior of snakes, the ingredients of Irish Spring soap, scientific evidence on its effectiveness, and alternative snake-repellent methods.

Snake Biology and Behavior

Before we discuss snake-repellent methods, it’s important to understand the biology and behavior of snakes.

Overview of Common Snake Species in Residential Areas

In residential areas, common snake species include:

  • Garter snakes
  • Rat snakes
  • Copperheads
  • Rattlesnakes

Snake Senses and How They Detect Their Environment

Snakes use various senses to detect their environment, including:


While snakes have poor eyesight, they can detect movement and changes in light.


Snakes use their sense of smell to locate prey and avoid predators.

Infrared Sensing

Some species of snakes, including pit vipers, have infrared sensors that allow them to detect heat from prey.

Factors That Attract Snakes to Human Habitats

Snakes may be attracted to human habitats due to:

  • Food sources, such as rodents or bird nests
  • Shelters, such as piles of leaves or debris
  • Water sources, such as swimming pools or fountains

Irish Spring Soap and Its Ingredients

Irish Spring soap is a popular home remedy for repelling snakes.

History and Original Purpose of the Soap

Irish Spring soap was first introduced in 1972 by Colgate-Palmolive. It was marketed as a soap that could make users “feel fresh and clean as a whistle.”

Breakdown of Key Ingredients

Irish Spring soap contains several key ingredients that are believed to repel snakes:


Irish Spring soap has a distinctive scent that is believed to repel snakes.

Chemical Compounds

Irish Spring soap contains several chemical compounds, including:

  • Sodium tallowate: A byproduct of animal fat that is used to create lather
  • Glycerin: A moisturizing agent
  • Parfum: A synthetic fragrance that gives the soap its distinctive scent
  • Sodium chloride: A salt that is used to harden the soap

Possible Reasons for the Belief that Irish Spring Soap Repels Snakes

There are several possible reasons why Irish Spring soap is believed to repel snakes:

  • The soap’s distinctive scent may be unpleasant to snakes
  • The soap’s ingredients, such as sodium chloride, may create an environment that is inhospitable to snakes

Scientific Evidence and Studies

While there is anecdotal evidence supporting the use of Irish Spring soap as a snake repellent, there is limited scientific evidence on its effectiveness.

Review of Existing Studies on Irish Spring Soap and Snake Repellency

One study conducted in 2015 tested the effectiveness of Irish Spring soap and other commercial snake repellents on captive timber rattlesnakes. The study found that none of the tested products, including Irish Spring soap, had a significant impact on the snakes’ behavior.

Results and Conclusions from the Studies

The results of the 2015 study suggest that Irish Spring soap and other commercial snake repellents may not be effective at repelling snakes. However, more research is needed to confirm these findings.

Comparisons with Other Snake Repellent Methods

Other snake-repellent methods that have been shown to be effective include:

  • Commercial snake repellents containing naphthalene or sulfur
  • Essential oils, such as cinnamon or clove oil
  • Plants that repel snakes, such as marigolds or wormwood

Alternative Snake Repellent Methods

While Irish Spring soap may not be the most effective method for repelling snakes, there are other options available.

Commercial Snake Repellents

There are several commercial snake repellents available in the market, including:

  • Naphthalene-based repellents: These products contain naphthalene, which is a chemical compound that is toxic to snakes.
  • Sulfur-based repellents: These products contain sulfur, which is believed to be unpleasant to snakes.

While these products may be effective at repelling snakes, they can also be harmful to humans and pets. It’s important to follow the manufacturer’s instructions carefully and keep these products away from children and pets.

Natural Snake Repellents

There are also natural snake repellents that you can use to deter snakes, including:

  • Essential oils: Essential oils, such as cinnamon or clove oil, have strong scents that may be unpleasant to snakes.
  • Plants that repel snakes: Some plants, such as marigolds or wormwood, are believed to repel snakes due to their strong scent.
  • Other household items: Some people believe that items like mothballs, sulfur powder, or even human hair can repel snakes.

While these natural remedies may be safer than chemical-based repellents, their effectiveness is not well-supported by scientific evidence.

Preventative Measures to Deter Snakes

In addition to using repellents, there are also preventative measures you can take to deter snakes from your property. These include:

  • Removing food sources and hiding spots: Keep your property free of debris, such as piles of leaves or brush, that can provide hiding spots for snakes or attract their prey.
  • Sealing entry points to the house: Make sure all doors, windows, and cracks are sealed to prevent snakes from entering your home.
  • Regular yard maintenance: Keep your lawn and landscaping trimmed and well-maintained to discourage snakes from nesting on your property.

Safety Precautions When Dealing With Snakes

If you encounter a snake in your home or yard, it’s important to take appropriate safety precautions.

Identifying Venomous vs. Non-Venomous Snakes

It’s important to be able to identify venomous vs. non-venomous snakes. Venomous snakes, such as rattlesnakes or copperheads, have distinct markings and should be avoided.

What to Do if You Encounter a Snake in Your Home or Yard

If you encounter a snake in your home or yard, follow these steps:

  1. Keep your distance: Do not approach the snake or attempt to handle it.
  2. Observe the snake: Take note of its size, color, and markings, as this information can be helpful for identifying the species.
  3. Give the snake an escape route: If the snake is inside your home, open a door or window to give it a way to escape.
  4. Call for professional removal: If you are unable to safely remove the snake yourself, call a professional snake removal service.

When to Call a Professional Snake Removal Service

If you are unsure how to safely remove a snake from your property or suspect that the snake may be venomous, it’s best to call a professional snake removal service. They have the equipment and expertise to safely remove the snake without putting you or the snake in danger.


While Irish Spring soap may not be the most effective method for repelling snakes, there are alternative snake-repellent methods available. It’s important to understand snake behavior and take necessary precautions to coexist peacefully with wildlife. Remember to prioritize safety when dealing with snakes and call a professional if you are unsure how to safely remove a snake from your property.
