Making garlic spray to repel insects, slugs, snails, and moles in your garden

Discover how to make your own garlic spray to repel garden insects, slugs, snails, and moles. With simple ingredients, create a natural and effective solution to protect your plants.

If you’re looking for a natural way to protect your garden from pesky insects, slugs, snails, and moles, then making your own garlic spray might be the solution you’ve been searching for. With just a few simple ingredients like fresh garlic cloves, sunflower oil, lemon juice, and water, you can create a potent repellent that will keep unwanted critters at bay. It’s important to use organic garlic for maximum effectiveness, as most supermarket varieties are bleached. By mincing the garlic and infusing it in lukewarm water overnight, you’ll have a powerful spray that can be further enhanced with the addition of dish soap and oil. Remember, though – don’t boil the garlic, as this can diminish its beneficial properties. Instead, use the spray once or twice a week, preferably during the evening, for the best results. The longer the garlic infuses, the stronger the spray will become. So why not give it a try and watch as your garden becomes a pest-free paradise?

Ingredients for Garlic Spray

To make homemade garlic spray, you will need the following ingredients:

Fresh garlic cloves

The key ingredient in garlic spray is, of course, fresh garlic cloves. Garlic has natural insect-repelling properties that can help keep pests away from your garden. It contains compounds that act as a natural pesticide, making it an effective and environmentally-friendly choice for protecting your plants.

Sunflower oil

Sunflower oil is used in garlic spray to help the spray adhere to the plants. It acts as a surfactant, allowing the spray to stick to the leaves and stems of your plants. This ensures that the garlic’s beneficial properties are effectively transferred to your plants and repel insects effectively.

Lemon juice

Lemon juice is another component of garlic spray that helps enhance its effectiveness. Lemon juice contains citric acid, which can help control pests and deter them from your plants. It also adds a fresh scent to the spray, making it more pleasant to work with.


Water is the base of the garlic spray and is used to dilute the other ingredients. It helps create a solution that is easy to apply and reduces the risk of causing any harm to your plants. Make sure to use lukewarm water when preparing the garlic infusion for the best results.

Benefits of Using Organic Garlic in Garlic Spray

When making garlic spray, it is highly recommended to use organic garlic. Here are some benefits of using organic garlic in your garlic spray:

Increased potency

Organic garlic generally has a higher potency compared to conventionally grown garlic. This means that the active compounds responsible for repelling pests are more concentrated in organic garlic, making your garlic spray more effective in keeping pests at bay.

Avoiding bleached garlic

Most garlic sold in supermarkets has been bleached to give it a whiter appearance. Bleaching garlic not only affects its natural color but can also diminish its potency. By choosing organic garlic, you can avoid using bleached garlic and ensure that you are using the most effective ingredients in your garlic spray.

Checking for organic options in supermarkets

While it may be challenging to find organic garlic in some supermarkets, it is worth the effort to check for organic options. Many supermarkets now carry organic produce sections, and you may find organic garlic there. If you can’t find organic garlic in your local supermarket, consider visiting farmers’ markets or specialty stores that prioritize organic and locally sourced products.

Preparing Garlic for Infusion

Before you can create garlic spray, you need to prepare the garlic cloves for infusion. Here is a simple method to prepare garlic for infusion:

Mincing garlic cloves

Start by mincing the garlic cloves. The smaller the garlic pieces, the more surface area will be exposed to the water, allowing the infusion process to happen more effectively. You can use a sharp knife or a garlic press to finely mince the garlic cloves.

Infusing in lukewarm water overnight

Place the minced garlic cloves in a container and cover them with lukewarm water. The lukewarm water helps extract the beneficial compounds from the garlic cloves. Allow the garlic to infuse in the water overnight, or for at least 24 hours, to ensure that the water absorbs as much of the garlic’s beneficial properties as possible.

Enhancing the Garlic Spray

To enhance the effectiveness of your garlic spray, you can consider adding a few additional ingredients:

Adding dish soap

Adding a small amount of dish soap to your garlic spray can help improve its effectiveness. The dish soap acts as a surfactant, helping the spray adhere to the plants more effectively. It also helps the spray penetrate the exoskeleton of soft-bodied insects, leading to their demise.

Including oil to help spray adhere to plants

Sunflower oil, which is one of the main ingredients of garlic spray, not only helps the spray adhere to the plants but also plays a role in suffocating pests. It acts as a coating, making it difficult for insects to breathe through their spiracles, ultimately leading to their demise. Ensure that you use a small amount of oil to avoid suffocating your plants or causing any harm to them.

Avoiding Boiling the Garlic

While it may be tempting to boil the garlic cloves to speed up the infusion process, it is best to avoid boiling the garlic for several reasons:

Beneficial properties of raw garlic

Boiling garlic can reduce its potency and diminish the beneficial properties that make it effective in repelling pests. Raw garlic contains sulfur compounds that act as natural insecticides, and these compounds can be destroyed or diminished when exposed to high heat.

Negative effects of boiling on potency

Boiling garlic cloves for an extended period may cause the active compounds to break down, resulting in a less potent spray. To ensure that you get the most out of your garlic spray, it is best to allow the infusion process to happen naturally over time without the use of high heat.

Ineffectiveness of Hot Pepper

While hot pepper sprays are commonly recommended as natural pest repellents, garlic spray is generally a better alternative. Here’s why:

Garlic as a better alternative

Garlic spray has been proven to be more effective in repelling pests compared to hot pepper spray. Garlic contains sulfur compounds that deter insects, slugs, snails, and moles, making it a versatile and potent pest control option.

Hot pepper’s ineffectiveness in repelling pests

While hot pepper sprays can be effective against certain pests, their effectiveness tends to be limited. Insects and other pests can often develop a resistance to hot pepper repellents, rendering them less effective over time. Garlic spray, on the other hand, is less likely to lose its potency and effectiveness against a wide range of pests.

Using Garlic Spray in the Garden

Once your garlic spray is prepared, it’s time to start using it in your garden. Here are some tips for using garlic spray effectively:

Frequency of use once or twice a week

To keep pests at bay, it is recommended to use the garlic spray once or twice a week, depending on the severity of the infestation. Regular application of the spray ensures that pests are constantly deterred and reduces the risk of damage to your plants.

Preferred usage during evening hours

Applying the garlic spray during the evening hours is preferred for several reasons. Firstly, it allows the spray to dry on the plants overnight, giving the garlic’s natural insect-repelling properties more time to work their magic. Secondly, it reduces the risk of leaf burn from the sun, as the sun won’t be as intense during the evening hours.

Increasing Potency of Garlic Spray

If you want to make your garlic spray even stronger, consider allowing the garlic to infuse for a longer period. Here are the benefits of allowing the garlic to infuse for an extended period:

Longer infusion for stronger spray

The longer the garlic infuses in the water, the more potent the resulting spray will be. Allowing the garlic to infuse for a week or more can significantly increase its effectiveness in deterring pests and protecting your plants.

Benefits of allowing garlic to infuse for an extended period

Extended infusion time allows for a more thorough extraction of the garlic’s beneficial compounds. It ensures that the spray contains a higher concentration of the natural insect-repelling properties found in garlic, providing you with a more potent and effective pest control solution.

In conclusion, garlic spray is a natural and effective way to repel insects, slugs, snails, and moles in your garden. By using fresh garlic cloves, sunflower oil, lemon juice, and water, you can create a powerful homemade spray that is safe for your plants and the environment. Remember to use organic garlic for increased potency and avoid boiling the garlic to preserve its beneficial properties. With regular use and careful application, garlic spray can be a valuable tool in your garden pest control arsenal.
