Aphids root is part of the phylloxera family originating from the eastern and southeastern parts of the United States. This species was first discovered in the 1850s and is known to have destroyed a vineyard in France in 1860. This pest also continued to appear in the years that followed.
Recently, its existence has become a nightmare for marijuana farmers. The larvae develop rapidly and form an infestation at the root. They can spread fast because they have wings that allow them to find other supplies of food when one source runs out.
Physically, these pests are shaped like a teardrop, with two protrusions at the end of their hinds. The root aphids’ size reaches 2.4 mm on average and has a yellowish-white colour. As mentioned above, these animals reproduce at the roots of plants.
The process of this pest invasion is not sudden. Root aphid larvae come to an area and start trying to survive there. Gradually, it will grow fast by absorbing the nutrients from the roots.

Over time, the tiny larvae that initially looked useless will begin to mature and reproduce. When the numbers grew and formed an infestation, then big problems finally arose. The roots of the plant have been taken over.
At first, you will not even notice what is going on. Plants will begin to dry up, the leaves start to turn yellow, and their growth will be unhealthy. No matter how much you water, the conditions do not change either.
When checked, everything also looks good. You hardly encounter any problems except for abnormal plant conditions. Finally, you find something surprising when you examine the root. The root aphids’ colony there was so strong that it seemed impossible to eradicate.
If allowed, of course, this will harm plant development. The roots attacked will slowly lose nutrients so that all parts of the body will wither and gradually die.
Root aphids will also easy to spread because they have wings that allow for high mobility. When one plant becomes too densely populated or runs out of nutrients, they quickly switch to other plants. And so on until nothing is left.

Root Aphids or Soil Mites?
The physical shape of it does look similar to several other organisms in the soil. When starting to grow in soil, most people will confuse the difference between root aphids or soil mites at first glance. Both have a white color with a shape like teardrops.
However, there are fundamental differences between the two. Soil mites do not have a rear abdomen like roots aphids. They are also two different types of animals. The root sucker is an insect with six legs, while the other is a type of spider that walks on eight legs.

Root Aphid Treatment
Using Citric Acid for Root Aphids
This one substance is also not used to eradicate, but only to prevent it. Compared to hydrogen peroxide, citric acid is safer because it is organic and non-toxic. The solution is safe enough to apply to soil and plants but effective enough to prevent pests from attacking.
Using Imidacloprid for Root Aphids
This insecticide, also known as dinotefuran, is highly recommended to eradicate pests. When sprayed, the chemicals will come to the roots. Because root aphids live by absorbing nourishment in that part, the use of this substance will be effective.
However, substances that enter the roots will slowly travel towards the top of the plant. Therefore, for imidacloprid to eradicate pests effectively, you need to apply it again about two weeks later.
Using BotaniGard for Root Aphids
This biological insecticide is known to be effective in eradicating various pests ranging from whitefly, spider mites, root aphids, and many more. BotaniGard contains beauveria bassiana, a species of fungus that is the main enemy of stubborn pests.
This insecticide spreads the spores to the pests that come into contact. In a short time, the fungus will thrive on their skin. Within 7-10 days, the fungus can cause death in various microorganisms, such as root aphids.
Using Avid For Root Aphids
Avid is a type of insecticide that is very effective in eradicating leaf miners, mites, and root aphids. Inside there is an active ingredient, namely abamectin that will attack the nervous system of insects. The pests that come into contact will become paralyzed, so they stop eating and die.
Uniquely, Avid also penetrates the plant tissue and forms a reservoir of active ingredients stored in leaf cuticles. This translaminar activity then becomes antibodies that keep pests from coming back.
Several product reviews have revealed that this substance has strong killing abilities. Aphids root reacted immediately after the application of Avid. After 24 to 48 hours, the pests will die.
However, there are some plants such as Shasta Daisy or ferns that are less adaptable to this solution. Using Avid on some plants will dry them out and die.
Using Hydrogen Peroxide for Root Aphids
Hydrogen peroxide is not effective in eradicating root aphids that are already multiplying. However, its use can prevent the presence of these pests. Just apply a small amount to the soil so that no disturbing organisms get close.
However, be careful when using it. Too much use will harm contaminated plants. Besides, this substance can also kill other good microbes that live in the soil.

The use of insecticides sometimes harms plants. Therefore, you may need a safer option, namely by placing other organisms that can fight it.
One thing you can do is spread the nematodes in the area that is attacked by root aphids. They are a kind of small parasitic worms that will attack the various insects that inhabit the soil. You can get it at garden centers.
Nematodes like moist places. Therefore, before spreading it, you must first do the watering. After that, you can spray the nematode mixture on the soil. The root aphids will begin to disappear within 24 to 72 hours. Repeat the application process if necessary.
Of course, there may still be several other alternatives, which can be an option for killing root aphids. The use of insecticides is indeed powerful. However, it is necessary to think about its future effects.
The use of ornamental plants may not cause serious problems. However, for the consumed plant, the poison may also transmit the disease to humans. The best way is to keep them from coming. Besides, you can also use natural predators to get rid of pests.
Apart from root aphids, you have to be aware of many other types of pests. Each of them has its character so that they may need different handling. That is why; you must have enough knowledge before starting to plant.
