Root aphids are annoying pests that attack your outdoor and indoor plants and can quickly cause an infestation in your entire garden. Aphids suck the sap from the plants, taking away the necessary nutrients the plant needs to survive.

Since acting fast to eradicate root aphids is a crucial step, there are several methods you can take to prevent or avoid the appearance of root aphids. Read the article below to learn about the most effective ways to eliminate these frustrating pests.

What are Root Aphids?

Root aphids are sap-sucking pests that inhabit plants and feed on their roots. They appear yellow, green, brown, or white. Aphids are the basis of many food chains, as many insects feed on them.

The 5 Expert Tips on How to Get Rid of Root Aphids

1. Neem Oil

Neem oil is a perfect natural insecticide to solve your aphid infestation safely. It works as an insecticidal soap, especially when mixed with dish soap. You can easily create a solution for all your plants without worrying about damaging them. Mix one teaspoon of neem oil with one teaspoon of dish soap. Dilute this with 1 quart of water, mix it, and pour it into a spray bottle or watering can. Spray the affected roots, stems, leaves, and soil with the spray bottle while avoiding sun exposure. Soak your affected plants during the evening, and repeat the process every week for 5 weeks.

2. Beneficial Insects

One of the easiest ways to deal with root aphids without investing a minute of your time is to let other insects deal with them. Introducing beneficial insects into your garden has multiple benefits, and one of them will be eradicating your aphid infestation. Nematodes are worm-like parasites you can add to the soil before it is even infected. These tiny creatures will take care of any pests that may wander around your plant. Another beneficial insect to use is the ladybug, which feeds on root aphids.


3. Hydrogen Peroxide

Hydrogen peroxide is a liquid primarily used for medicinal purposes, but it also has uses in gardening. It can help prevent aphid infestation as well as spider mites. Hydrogen peroxide is also efficient as a disinfectant spray for cleaning. Pour 3% hydrogen peroxide into a spray bottle and spray on the bugs directly. If there are bugs on the stems and leaves of the plant as well, use this solution as a foliar spray.

4. Prevention

The best way to keep your garden healthy for a long time is to prevent any infestation from happening in the first place. You can take several preventive measures to avoid root aphids, such as regularly cleaning your gardening tools and practicing good hygiene. Make sure to look out for signs of infestation on time so that you can act as soon as possible and increase your chances of eradication. These pests can travel from one infected tool to other crops and plants, so make sure to sanitize them after each use.


5. Your Last Resort

Your last resort to saving your garden from root aphids should be eliminating the entire infected plant. While this can be difficult—especially if you have the plant for several years—if the infestation has progressed, it can be your only way to save your other plants. Leaving the plant infested for longer increases the risk of root aphids spreading to your entire garden and ruining your crops, fruits, vegetables, and even trees.

Root aphids are nasty pests that quickly multiply to take over your entire garden. You will quickly notice these tiny, green creatures lying still around your plant or soil and realize you have an aphid infestation.
