Garlic is more than just a kitchen staple—it’s a powerful, natural insect repellent that can protect your plants without relying on harmful chemicals. With just a few simple ingredients and tools, you can create a cost-effective and non-toxic garlic insect spray to keep pests at bay. Let’s explore how to make and use this eco-friendly solution for your garden.

When to Apply DIY Garlic Insect Spray

It’s best to use the spray as soon as you spot the telltale signs of pest infestations. Look out for holes in leaves, yellowing foliage, or the presence of insects like aphids, caterpillars, or spider mites. Garlic’s sulfur compounds work to disrupt pests’ nervous systems and repel them effectively. With regular application, you can prevent minor infestations from turning into major problems.

Preparation

Ingredients You’ll Need:

• 4-5 cloves of fresh garlic
• 1 quart (4 cups) of water
• 1 teaspoon of liquid soap (mild or biodegradable)
• Optional: 1 tablespoon of vegetable oil and 1 tablespoon of vinegar

Tools Required:

• Mixing bowl
• Garlic press or knife
• Strainer
• Spray bottle

Guide on DIY Garlic Insect Spray

Step 1: Crush the Garlic
Begin by crushing 4-5 cloves of fresh garlic. Let the crushed garlic sit for 10-15 minutes to maximize allicin production, which is the compound responsible for its insect-repelling properties.

Step 2: Infuse the Mixture
Combine the crushed garlic with 1 quart (4 cups) of water in a mixing bowl. Allow this mixture to sit for at least 24 hours to fully infuse and extract the garlic’s active compounds.

Step 3: Strain and Mix
Strain the mixture through a fine mesh strainer or cheesecloth to remove solid garlic pieces. Add 1 teaspoon of liquid soap, which helps the spray adhere better to the plants. For added potency, mix in 1 tablespoon each of vegetable oil and vinegar. These optional ingredients enhance the spray’s effectiveness by smothering soft-bodied insects and further repelling pests.

Step 4: Transfer to a Spray Bottle
Pour the prepared mixture into a clean spray bottle. Ensure the bottle is properly sealed and shake it gently before use to combine all ingredients.

Step 5: Apply to Plants
Spray the garlic solution onto your plants, focusing on both the tops and undersides of the leaves where pests often hide. This thorough application ensures the solution reaches the insects and their eggs.

Notes When Using DIY Garlic Insect Spray

• Timing: Apply the spray once a week during the early morning or late evening to avoid scorching your plants under the sun.
• Reapplication: If you’re dealing with a severe infestation, apply the spray every few days until the pests are under control.
• Indoor Plants: When using the spray indoors, ensure proper ventilation to minimize the strong garlic odor.
• Avoid Overuse: While garlic spray is effective, excessive application can harm beneficial insects like bees, so use it selectively on problem areas.
