5 Best ways how to get rid of aphids naturally

Many gardeners battle with aphids. These universally hated garden pests are small, but they can wreak havoc on a plant and turn the most beautiful garden into something that looks like it belongs in Dr. Seuss’s world!

There are about 5,000 species of aphids – small, soft-bodied insects that suck the juice from the infested plant. Aphids feed on plant sap and often cluster on the undersides of leaves and along stems. They can cause a plant to wilt or produce poor quality flowers and vegetables. 

Fortunately, there are many natural ways to control aphid populations in your garden without using toxic chemicals.

Prevention and plant care

Remove any diseased leaves or branches from the plant to help slow down aphid infestation

If a plant is heavily infested, you might choose to cut off some stems and leaves.

Keep an eye out for ants – they often come along when there is an aphid infestation as they feed off the honeydew left behind by aphids.

Remove aphids by hand

Although aphids multiply quickly, they move slowly and can easily be removed by hand or dislodged with water by spraying the plants. Physical outright removal of aphids is always the best option, when possible.

If you choose the latter option, use a strong jet of water from the garden hose to knock them off the plant, but not so strong that it might damage the plant’s stem or leaves. It helps to place your free hand behind the leaf you are squirting to give it support.

If you choose to get rid of them by hand, put on your garden gloves (squishing aphids is pretty yucky), and wipe or brush the aphids off into a bucket of soapy water.

You can also just pinch off the leaves or prune the areas of the plant where the aphid infestation is.

Use natural, organic treatments

Speak to any organic gardener and they’ll tell you their own special recipe for organic aphid control. One popular natural treatment are insecticidal soaps which is simply dish soap and water in a spray bottle. 

The soapy solution coats the aphids’ bodies and will slowly dissolve their protective outer ‘skin’!

GrowSafe is an organic natural product that works well on aphids. It kills soft body insects on contact and is very effective on spider mites, whiteflies and aphids. It also works to treat powdery mildew and downy mildew. Best of all, GrowSafe contains all-natural and organic food-based ingredients that are non-toxic and safe for humans, pets, bees, ladybugs and other beneficial predators.

Other gardeners like to make up treatments from garlic, essential oil, or neem oil. Neem oil might also deter some beneficial insects too though.

Whatever ‘recipe’ you choose, the application is the same. Fill the spray bottle and spray liberally over the plant. Make sure you coat all parts of the plant, paying special attention to the undersides of the leaves.

Repeat this every few days as needed.

Some gardeners like to place sticky traps near plants to catch any new pests. The risk with these of course is that they can also catch beneficial insects so we don’t recommend this route.

Diatomaceous Earth

Another method to get rid of aphids is to sprinkle diatomaceous earth in your garden. Diatomaceous earth (DE) is made of fossilized remains and has sharp edges that cut through the outer tissue of insects, causing death by dehydration. 

Again though, be sure not to use this where bees and other beneficial insects can be harmed. Sprinkling DE on the soil beneath any infected plants is a safer option, as bees tend to focus on flowers, not the soil. That way any aphids that fall off the plant are likely to be dealt with by the DE.

Use other natural predators

There are many beneficial insects which prey on aphids without harming other garden inhabitants. I use a combination of four different natural predatory insects in my garden and they do a great job at keeping the pests to a manageable minimum.

Ladybugs

Ladybugs (also called ladybirds and lady beetles) can be introduced as an organic way to get rid of pests such as aphids. Ladybugs and their larva eat aphids, and you can purchase ladybugs online or even from some specialist garden centers and nurseries.

Keep them in your refrigerator for up to 2 weeks so you can release them in batches over time. It is best to release them at dusk/night when they are less active so they don’t immediately fly away. Sprinkle them on the soil at the base of the plant as they like to climb up on their own.

Green Lacewing

Another insect predator that feeds on aphids is the green lacewing. Again, these can be bought online and are usually purchased as eggs that have been pre-glued onto hang tags. Simply hang these on your plants that tend to have pest problems and the eggs will hatch over time.

Lacewing are voracious eaters of aphids, spider mites, thrips, whiteflies, mealybugs, small caterpillars, eggs of leafhoppers, moths, and leaf miners. Some say they are even better than ladybug.

Praying Mantis

The third predator I love using in the garden is the praying mantis. This might be my favorite because they can eat quite a bit and since they are ambush hunters, they tend to stick around.

I’ve had one that has lived on the same plant for months and months just getting bigger and bigger. They are quite fun to watch and you can even hold them.

They can be a little pricey if you buy them as young mantids, so I always purchase eggs (Ootheca) and keep them in a ventilated cup so I know exactly when they hatch (usually in the late spring once it gets warm). Then on the day they hatch I sprinkle them out throughout the garden. One egg can hatch over 100 mantid!

Jumping Spiders

I always love finding jumping spiders in the garden. They are not picky eaters and will devour everything from aphid to flies to moths to caterpillars to grasshoppers.

Because of this, they are probably THE BEST predator to have in your garden, especially if you also have a problem with cabbage loopers and moths. Jumping spiders don’t make annoying webs and will usually just build a small nest in some out of the way corner.

They will travel from plant to plant to hunt for food during the day, but usually return to their nest at night. The ones in my garden tend to keep several plants in a row pest free and are permanent residents.

I think they are adorable and if you have kids they are fun to hold and easy to keep as pets too!

Companion planting

Certain plants naturally repel aphids, and other plants attract them. You can also introduce plants that attract aphids’ predators, the beneficial insects.

By practicing companion planting with the 3 different types of plants, you can avoid many cases of aphid infestation.

Use yarrow, clover, mint, dill or fennel to attract beneficial insects like parasitic wasps.

Alliums tend to repel aphids, so plant garlic, chives and onion to steer aphids away.

Many pretty flowering annuals are beacons to aphids, so plant dahlias, zinnias, and nasturtiums to attract aphids away from your other plants. Knowing that aphids like them, you might want to keep an eye on these distraction plants and chop off any newly infested growth.

Sadly, aphids also love roses, so if you have roses in your garden, check them regularly for any new aphid attacks!

Conclusion
