Gardening is a fantastic hobby that allows us to connect with nature, enjoy fresh produce, and create beautiful outdoor spaces. However, one of the challenges gardeners often face is dealing with pests that can wreak havoc on our plants. While there are many chemical-based products available on the market, using natural remedies can be just as effective and safer for the environment. In this article, we will explore the benefits of using crushed garlic cloves in the garden to deter pests.

How Does Garlic Work as a Pest Deterrent?

Garlic has been used for centuries as a natural remedy for various ailments, thanks to its strong aroma and potent properties. When used in the garden, the pungent smell acts as a deterrent to many common garden pests. The sulfur compounds in garlic disrupt the insects' smell receptors, making it difficult for them to locate their food sources. Additionally, garlic contains natural insecticidal properties, which can kill or repel pests.

Preparing and Using Crushed Garlic in the Garden

Now that we understand how garlic works as a pest deterrent, let's explore how to prepare and use it effectively in your garden:

1. Creating Garlic Pest Spray

To create a homemade garlic pest spray, follow these simple steps:

  • Finely chop or crush several garlic cloves.
  • Place the crushed cloves in a jar or container with water.
  • Allow the mixture to sit for at least 24 hours, ensuring the garlic's active compounds infuse into the water.
  • Strain the mixture to remove any solid pieces, and transfer the liquid into a spray bottle.
  • Dilute the garlic spray by adding water, using a ratio of 1 part garlic mixture to 10 parts water.

2. Applying the Garlic Spray

Once you have prepared the garlic spray, it's time to apply it to your plants:

  • Ensure your plants are well-watered before applying any spray.
  • Begin by spraying a small test area of your plants and monitor for any adverse effects over the next 24 hours.
  • If the test area shows no signs of damage, proceed to spray the entire plant, making sure to cover both the upper and lower surfaces of the leaves.
  • To increase the spray's effectiveness, apply it during cooler periods, preferably in the early morning or late evening.
  • Reapply the garlic spray every 7 to 14 days or after heavy rainfall to maintain its effectiveness.

Pests Repelled by Garlic

Garlic is known to repel a wide range of common garden pests, including:

  • Aphids: These small, soft-bodied insects can cause severe damage to plants by sucking sap from their leaves and stems. Garlic spray acts as a natural aphid repellent.
  • Snails and Slugs: These slimy pests feast on tender leaves and can often be a nuisance in the garden. A garlic barrier can deter them from approaching your prized plants.
  • Japanese Beetles: These notorious pests feed on the foliage of many garden plants. The strong odor of garlic keeps these beetles away from your flowers and vegetables.
  • Mosquitoes: Garlic's strong scent repels not only pests that harm our plants but also those that bother us. Planting garlic near seating areas or using a garlic-based repellent can help keep mosquitoes at bay.

Additional Tips and Considerations

Here are a few additional tips to make the most of using crushed garlic cloves as a pest deterrent in your garden:

  • Rotate your pest deterrents: While garlic can be highly effective at repelling pests, it's always a good idea to rotate your pest deterrents to prevent any potential adaptation by insect populations.
  • Experiment with other ingredients: Enhance the effectiveness of your garlic spray by adding other natural ingredients, such as chili peppers, onions, or neem oil, to tackle a broader range of pests.
  • Regularly inspect your plants: Stay vigilant and monitor your garden regularly for pest infestations. Early detection allows for prompt action, reducing potential damage to your plants.
  • Consider companion planting: Planting garlic near susceptible plants can act as a natural defense mechanism. For example, planting garlic near roses helps deter aphids.
  • Protect beneficial insects: While we aim to repel harmful pests, it's essential to protect beneficial insects like bees and butterflies that play a crucial role in pollination. Avoid spraying garlic on plants that attract these helpful pollinators.


Using crushed garlic cloves in the garden to deter pests is an inexpensive and environmentally friendly alternative to chemical-based pest control. It's easy to prepare and apply, and its effectiveness against a wide range of garden pests makes it a valuable addition to any gardener's arsenal. Give this natural pest deterrent a try and experience the benefits of protecting your plants while enjoying the rewards of a thriving garden.
