Natural Ways to Kill Aphids



Grow flowers like marigolds, nasturtiums, and sunflowers in your garden to get rid of the pest naturally. To repel aphids, plant herbs like catmint, lavender, turmeric, ginger, and oregano. Vegetables that aphids don’t like are onion and garlic.

Another way to get rid of aphids is to grow the plants that repel them between the rows of your vegetable patches, garden beds, and ornamental plants that are particularly loved by aphids like eggplants.

2. Garlic

Garlic has a pungent smell that aphids hate – you can take advantage of this weakness by making a garlic aphid killer spray. Add 100 gms of crushed garlic cloves in 1 gallon of water and allow it to sit for 24 hours. The next day, boil it for 20 minutes for decoction. Allow it to cool and fill the liquid in the sprayer for use.

3. Onion

Chop 100 grams of onions and mix them in a gallon of water. Cook it for 30 minutes. Use it without diluting in water. Make sure to cool the solution down to room temperature before applying. Use it within the same day.

4. Dandelion

There are many medicinal properties in the plant that makes dandelion useful, one of that property is it can kill aphids. Take 400 gms (0.8 pounds) of dandelion leaves, add 2 liters of water, and allow it to sit for a day. Fill this solution in a spray bottle and use it on affected plants.

5. Nettle

Stinging nettle can be used to make an anti-aphid spray. Don’t forget to wear gloves while picking its leaves as it causes stinging pain and itchiness.

Harvest 1 kg (2.2 pounds) leaves and add 2 gallons of water. Let it sit for two to three weeks until it becomes clear brown. Use it to kill aphids by mixing 1 part of the solution in 7 parts of water and spray it on plants. Store the remaining solution and use it within a month.

6. Dawn Dish Soap

Mix 1 to 1.5 teaspoon of dawn dish soap in a gallon of water and fill the solution in a spray bottle. Use it on the infected plant, especially the undersides of foliage.

7. Vinegar

Vinegar contains water and acetic acid that acts as a natural pesticide and burn aphids. Mix white vinegar with water in 1:3 proportion. Fill this solution in a spray bottle and use it on the parts of the plants affected by aphids. Repeat the process after one week to remove any remaining pests.

8. Neem Oil

To kill aphids, neem oil is the safest solution that you can use. You can soak a cotton ball in neem oil and apply on them or make a spray using 1 cup neem oil, 1 spoon of dawn dish soap in a gallon of water and spray it on the plant.

9. Pepper

Add 3-5 teaspoons of pepper along with 1 teaspoon of dawn dish soap in a gallon of water and spray it on the affected parts of the plant to get rid of aphids. Repeat the process if needed.

10. Wood Ash

All you have to do is to sprinkle a handful of wood ash on the affected area of the plants. The ash will dehydrate and suffocate aphids in no time!

Note: Always test them on a small portion of a leaf and wait for a day to see the result before using them on the entire plant.

11. Strong Jet of Water

Spray a strong stream of water on the infected plants to wash off aphids. This is also a good idea to get rid of them organically.

12. Diatomaceous Earth

Dust the affected plant with diatomaceous earth. The aphids will fall off and die in approx 12 hours.

13. Invite Birds

Grow a mat of shrubs, make a birdhouse, set a birdfeeder, a cute birdbath to invite bug-eating birds into your garden. Chickadees, wrens, and titmice enjoy eating bugs like aphids.

14. Essential Oils

Another organic way to get rid of aphids is the use of essential oils. While they may not kill aphids but will keep them at bay. Peppermint and Lavender oil are good for this purpose. You can also mix them in your spray recipes.

15. Handpick Aphids


You can also remove aphids by hand if there is not much in numbers. Squash them, don’t forget to wear gloves as they’re sticky.

16. Invite Beneficial Insects

Encourage beneficial insects like ladybugs, lacewings, praying mantis, and hoverflies in your garden.

17. Control Ants


If you want to control aphids, control ants first as they work together as a team in gardens, aphids secrete honeydew, which is a favorite dessert for ants.

18. Rubbing Alcohol

Prepare a solution of rubbing alcohol and water in a ratio of 1:8, do a patch test first on a small leaf. Spray the plant, leave it on for 15-20 minutes, and rinse with water. If required, repeat after a week.

19. Leftover Wine

Soak a cotton ball in leftover wine and pat it on aphids. It works best on the small infestations on houseplants. Use it once a week till infestation disappears.
