If you don’t want to use chemicals, use these 25 Natural Aphid Killing Methods. This is a lot more eco-friendly and effective way to deal with pests.
1. Grow Aphid-repelling Plants in Your Garden
Get rid of pests in your garden by planting flowers like marigolds, nasturtiums, and sunflowers. There are many other types of herbs that can be used effectively to keep aphids away from your plants like catmint, oregano, turmeric, lavender and ginger. Also, two very common vegetables that Aphids don’t like because they have a strong flavor are onions and garlic.
Additionally, aphids can be eliminated by growing plants that repel them in between the crops, garden beds and decorative plants that aphids are particularly fond of, such as eggplants.
2. Make Use of Liquid Dish Soap
Fill a spray bottle halfway with a gallon of water and 2 to 4 tablespoons of liquid soap. Apply it to the affected plant, paying specific attention to the undersides of the leaf.
3. Prepare a Spray with Garlic
Garlic has a strong odour that insects despise; you can exploit this vulnerability by creating a garlic aphid killer spray.
Pour 1 gallon of water over 100 grams of crushed garlic and let it soak for 24 hours. Boil it for 20 minutes the next day to make a decoction. Allow it to cool before filling the sprayer with the liquid.
4. Make a Vinegar Solution
Acetic acid in vinegar functions as a natural insecticide and burns aphids. In a 1:3 ratio, combine white vinegar and water.
Fill a mister bottle with this solution and spray it on the aphid-infested sections of the plants; if desired, do a patch test first! After one week, repeat the technique to remove any leftover pests.
5. Make a Dandelion Infusion
Dandelion has several medical features that make it valuable, one of which is that it can kill aphids.
Allow 400 gms (0.8 pound) of dandelion leaves to soak in 2 liters of water for a day. Fill a spray bottle with this solution and spray it on the afflicted plants.
6. Make Use of Neem Oil
Neem oil is the most effective and safest option for killing aphids. You can apply Neem oil to them by soaking a cotton ball in it, or you can make a spray recipe.
7. Make a Mix of Pepper and Dawn Dish Soap
To get rid of aphids, mix 3-5 tablespoons of pepper and 1 teaspoon of Dawn dish soap in a gallon of water and spray it on the problematic sections of the plant. If necessary, repeat the procedure.
8. Utilize Wood Ash
Simply sprinkle a handful of wood ash on the damaged plant area. The ash will quickly dry and drown aphids.
Prior to the introduction of pesticides, this was one method of aphid control.
9. Make Use of an Onion Solution
100 grams of onions, chopped, in a gallon of water 30 minutes in the oven It should not be diluted with water.
Before applying, allow the solution to cool to room temperature. Use it within one day.
10. Powerful Water Jet
A strong stream of water on affected plants will wash the aphids away. This is also an excellent way to get rid of them organically.
11. Use Diatomaceous Earth
Diatomaceous earth should be applied to the damaged plant. The aphids will fall off and die within 12 to 24 hours.
12. Attract Birds
Make a shrub mat, a birdhouse, a birdfeeder, and a charming birdbath to attract bug-eating birds to your garden. Aphids are a favorite food of chickadees, wrens, and titmice.
13. Make Use of Essential Oils
Essential oils are another natural technique to get rid of pests. Even though they might not kill aphids, they will keep them from spreading. Peppermint oil and lavender oil both work well for this. You can also mix them into the recipes for your sprays.
14. Pick Off Aphids By Hand
If there aren’t a lot of aphids, you can also remove them by hand. Wear gloves because they’re sticky if you don’t want to crush them with your fingers.
15. Attract Predatory Insects
Ladybugs, lacewings, praying mantis, and hoverflies are examples of helpful insects to encourage in your garden.
16. Control Ants
Aphids are easier to control when ants are under control, because they operate in harmony with one another in gardens. Aphids secrete honeydew, a favorite snack of ants, and to assure a continual supply of it, ants defend aphids by building a colony around them.
17. Make Use of Leftover Wine
Put some left-over wine on a cotton ball and rub it on aphids. Small infestations on houseplants are where it works best. Use it once a week until there are no more bugs.
18. Use Alcohol for Rubbing
Prepare a 1:8 solution of rubbing alcohol and water and perform a patch test on a tiny leaf first. Spray the plant, then rinse with water after 15-20 minutes. If necessary, repeat after a week.
19. Draw them in Using a Trap Crop
You can also grow plants that aphids like to eat, which will keep them busy so they don’t harm your valuable plants. It’s a strategy to keep aphids under control while keeping predatory insects around the garden.
Grow some bait crops like cosmos, dahlias, zinnias, and asters in a location far enough away from the plants you want to protect against pests. These will attract aphids, which you may subsequently destroy using one of the methods indicated above.
20. Prepare a Suffocating Solution
Shake together 2 cups of vegetable oil and half a cup of soap to make a solution. Keep in mind that you should dilute this solution with 5 to 10 liters of water before spraying it directly on leaves rather than using it as is. Aphids get suffocated and die when you spray this solution on them.
21. Use Lime and Sulfur Liquid
Aphid control can be greatly improved by use these two highly caustic substances. As a pesticide, sulfur and lime combine their anti-fungal properties to produce a potent mixture.
Only use on aphids when you see them. Please follow the directions on the label. Using them safely also means wearing gloves and a mask.
22. Use Baking Soda
Aphids, mites, and whiteflies can all be eliminated using baking soda. Make your own at home by mixing 500ml of warm water with 1/3 teaspoon baking soda. Toss in a half-teaspoon of extra virgin olive oil and combine thoroughly. 7-8 drops of liquid soap can be added to the solution to improve its efficacy even further.
23. Utilize milk
Powdery mildew and aphid populations can be controlled by using milk in the garden. It has been shown to lessen their infection by 30-40 per cent in research.
Spray a 1:1 mixture of milk and water on plants infested with aphids.
24. Use a Coca-Cola solution to spray
Phosphoric acid (E338 or acid stabilizer) is found in Coca-Cola and other carbonated beverages. Aphids are effectively eradicated by this treatment.
Add water and soda to a mister bottle, shake well, and spray where you see aphids.
25. Prepare an Aphid-Eliminating Spray Using Nettle
An anti-aphid spray can be made from stinging nettle. If you’re going to be plucking its leaves, be sure to use gloves because they induce stinging and itching.
Add 2 litres of water to 1 kilogram (2.2 pounds) of leaves. Allow it to sit for two to three weeks until it turns a light brown colour. Spray it on plants by diluting one part of the solution in seven parts of water and sprinkling it over the plants. Use the remaining solution within a month after storing it.
