Pests can be a significant issue for plant enthusiasts, especially when they damage their precious plants. Chemical pesticides can be effective, but they often carry risks for humans, animals, and the environment. Fortunately, nature provides an alternative in the form of essential oils. With their natural and safe properties, essential oils can help repel pests in an environmentally friendly manner. Here, we discuss some of my favorite essential oils for your plants and how you can use them to protect your plants.
Which oils for what?
Thyme: Thyme is known for its powerful antimicrobial and insect-repelling properties. Mix a few drops of thyme oil with water and a bit of liquid soap, then spray this mixture on plants affected by aphids, mites, or other small insects.
Peppermint: Peppermint has a strong scent that repels many insects, including ants, cockroaches, and spiders. Place cotton balls soaked in peppermint oil around affected areas of your garden or in the plant pots, or add a few drops to a spray bottle with water and spray it on plants and around them.
Eucalyptus: Eucalyptus is effective against mosquitoes, flies, and beetles. Dilute eucalyptus oil with water and use it as a natural spray. It can also help repel rodents such as mice and rats.
Sandalwood: Sandalwood has a discouraging effect on termites and mosquitoes. Add a few drops to the water when watering plants or place cotton balls soaked in sandalwood around the plants in your garden or indoors among the pots.
Spruce: Spruce can be used to repel slugs, which often damage leaves and crops. Apply a few drops of spruce to the edges of planters or around garden beds. Ideal if you want to start your own vegetable garden with natural pest control.
Lavender: Lavender has a pleasant scent for humans but is unpleasant for many insects, including moths, mosquitoes, and fleas. Use a few drops of lavender oil on cotton balls and spread them around the garden. I also add this to my daily plant spray.
Lemon: Lemon is effective against flies and mosquitoes due to its refreshing scent. Add a few drops to a spray bottle with water and spray this mixture on plants and around the garden.
Patchouli: Patchouli has powerful insect-repelling properties and can be used to keep mosquitoes, ants, and fleas at bay. Mix a few drops of patchouli with water and use it as a spray or on cotton balls.
Clove: Clove is effective against ants and mosquitoes due to its strong scent. Mix a few drops of clove with water and spray it on problem areas in the garden or indoors.
Basil: Basil can help repel mosquitoes and flies. Use it as a natural spray by mixing a few drops of basil with water and applying it to plants.
Rosemary: Rosemary has antimicrobial properties and can help repel insects such as aphids and moths. Add a few drops of rosemary to water and use it as a spray.

When using essential oils for pest control, it's important to be cautious and dilute the oils before applying them to plants to prevent damage. Additionally, regular application is often necessary, especially after rain or watering, as essential oils evaporate quickly. With this natural approach to pest control, you can enjoy a lush and healthy garden without harmful chemicals.
I personally create a preventive blend of Thieves, Purification, lemon, lavender, and peppermint to combat a wide range of pests. Additionally, I add specific oils to the blend when pests appear. I use the spray every other day for my plants.
The recipe: 750 mL water 2 drops Thieves 2 drops Lemon 2 drops Purification 2 drops Lavender 2 drops Peppermint
When a pest issue arises, I always take a moment to research the anatomy of the pest, such as spider mites. This helps me determine which oils to use for treatment.
