Among the most destructive garden insects, aphids may cause stunted plants and distorted leaves. However, there are many home remedies and natural solutions to control them.
Otherwise called greenflies, aphids suck sap from plants. They also secrete a sticky substance that can attract ants and other insects .
Here’s how to get rid of aphids naturally.
1. Neem Oil
Neem oil is excellent for killing aphids naturally. It also works great against other pests in your garden.
Combine one tablespoon of neem oil suitable for garden use, one tablespoon of liquid soap, and a gallon of water. Finally, pour the solution into a bottle and spray your plants.
2. Essential Oils
Essential oils can keep certain pests out of your garden. Anise, basil, fennel, peppermint, and pennyroyal essential oils all work against aphids 
Therefore, mix 2 ounces of essential oil of choice with a gallon of water. This makes a wonderful spray for getting rid of aphids organically.
Not only will it kill these small green bugs that fly, but it will work on the eggs too.
3. Soap Spray
Use organic liquid soap and water to make a mild aphid soap spray that is suitable for your vegetable garden.

5. Garlic Spray
You can also use garlic to make a homemade greenfly spray. Get some mineral oil, fresh garlic, a teaspoon of liquid soap, and 2 cups of water.
Chop up 4 cloves of the garlic and let them sit overnight in 2 teaspoons of the mineral oil. Next, strain and add the garlic oil to the 2 cups of water.
Now add the liquid soap. Some people use regular dish soap but we use organic ingredients in our recipes.
Finally, shake well and spray the solution all over your plants. This garlic repellent spray will force greenflies to stay away as they hate the smell.
6. Vinegar Solution
Vinegar solution is commonly used to deter many garden pests, including plant louse.
To make a natural aphid spray using vinegar, combine 1 tablespoon of liquid soap, 4 tablespoons of white vinegar, and a gallon of water.
Finally, add to a spray bottle and use the solution to coat the affected plants.
7. Diatomaceous Earth (DE)
Another great home remedy to kill green flies is diatomaceous earth. It will dehydrate them to death.
Lightly dust the leaves of affected plants. Alternatively, make an aphid killer spray by combining 5 tablespoons of diatomaceous earth with a gallon of water.
Use the spray to coat the affected plants but ensure it is not heavily dripping. Also, reapply once there’s a heavy downpour of rain. The solution will kill the pests when it dries out.
8. Hose Them
This is another effective home remedy for getting rid of aphids on plants.
Select the hard jet-setting and spray away at your leaves. However, use this DIY method with caution to avoid damaging your plants in the process.
9. Trap Crops
This is a clever pest control method to get rid of aphids on roses, tomato plants, dahlias, and other plants that they love.
Trap crops will draw these pests away from your main crops. Plant nasturtiums and sunflowers in your yard to attract aphids.
10. Encourage Birds to Come Around
Putting out bird feeders will help to attract birds that feed on bad insects and related pests in your garden. Birds such as sparrows, swallows, chickadees, and wrens eat aphids.
11. Aluminum Foil
Place aluminum foil on the ground underneath your plants. This will reflect light on the undersides of leaves which will deter aphids.
It will also help retain soil moisture. But, remember to pick up the foil when the gardening season is over to protect the environment.
12. Pest-Repelling Plants
This is another excellent aphid control remedy. Dill, garlic, catnip, rosemary, onion, and basil are some plants that repel aphids (greenflies).
Therefore, plant these around your garden to keep away the critters.
13. Remove by Hand
Knock them off plants into a container with soapy water. You can also wipe them away with soapy water. They will suffocate.
14. Squish the Eggs
Remove the eggs from the leaves and squish them. Destroying greenfly eggs will disrupt their life cycle.
While the eggs are not an immediate threat, as soon as they hatch, the nymphs will start feeding on your plants. No eggs mean no adults later on.
15. Get Rid of Ants
Ants are sometimes the culprits protecting aphids. So, you might want to focus on getting rid of ants if you see a lot of them in your garden.
16. Onion Spray
Use onion to make a homemade spray that repel green flies. Puree one onion in a cup of water. Finally, strain and spray affected plants.
Greenflies hate the smell of onion. Use the measurement as a guide for bigger treatment concoctions.
17. Beneficial Insects
Aphid predators include ladybugs, lacewings, damsel bugs, soldier beetles, and parasitic wasps.
18. Safe Commercial Pesticides
Perhaps the easiest and quickest way of eliminating of an aphid colony is to invest in safe and natural pesticides such as these:
