Some Bugs Are Immune to Synthetic Pesticides

Another reason to prioritize organic materials in eradicating bugs in garden soil is that some pests are resistant to toxic chemicals. 

Some of them even came back stronger than before.

Instead of helping you maintain the garden from bugs attack, the use of pesticides will only have a negative impact many times more than its ability to eliminate garden pests.

It has also been recognized by Planet Natural Research Center that synthetic pesticides are no longer the best option in this regard.

The ultimate way to control the growth of bugs in garden soil is to ensure that the soil type matches the character of the crops you want to grow. 

Moreover, it is essential to provide proper and regular treatment to maintain soil fertility.

Where the Bugs in Soil Come From?

Where the Bugs in Soil Come From

It is easy. Bugs come from previously infected soil. It is like buying a new plant and immediately cultivating it in the garden.

Otherwise, put your new potted vegetables close to other plants without going through the quarantine process first.

These conditions will allow the bugs to move to other lands and continue to dwell and breed there. Thus, quarantining the plants you just bought is essential so that no bugs can infest your garden soil.

Bugs That May Live in Your Garden Soil

Bugs That May Live in Your Garden Soil

Once mentioned one by one, there are many types of bugs that you can find in your garden. However, the eight below are those that live on the garden soil. 

Also, they have the potential to disturb and even damage your favorite plants.

Vine Weevil and Its Grubs

Vine Weevil and Its Grubs

Vine weevil is a black plant pest native to Europe but is still common in North America.

Vine weevil prefers plants in pots or counters instead of attacking plants that grow on the grounds, both outdoor and houseplants.

During the larvae stage, vine weevils will live in garden soil and get their food source from plant roots. While as adults, they start to live and eat the plant’s leaves.

Allowing the presence of vine weevils, especially the grubs on the garden soil, is a fatal mistake that will lead you to have unhealthy vegetable plants.

Fungus or Soil Gnats

Fungus or Soil Gnats

Fungus gnats are tiny-flying bugs that are usually black in the body and live in the soil. The adult ones will lay their eggs on the ground until they hatch during the breeding season.

When the newly hatched become larvae, they will eat plant roots and take many nutrients from the surrounding soil material.

You can easily find this pest crawling around the plants’ stem, soil first layer, and outside the pots.

Soil Mites

Soil Mites

Soil mites are microscopic insects that you can only see using a microscope. Generally, their body ranges from 1-2 mm only. 

Furthermore, these mites live in the soil, and not all types interfere with plant growth.

Some beneficial mites will help recycle the nutrients contained in the soil. Meanwhile, those who are evil will damage your plants. 

That is why you should get rid of these bugs as soon as possible.

In some cases, soil mites will carry eggs of tapeworms, bacteria, and parasites that are also harmful to humans.

Although there is no moment when you will eat the mites directly, there is a possibility that these micro insects will enter your nails when you are gardening without using gloves. 

It will get worse when you decide to go to lunch without washing your hands first.

Soft Scales

Soft Scales

Soft scales are white-waxy bugs that commonly eat sap juice on plants.

Although they generally live in the soil, you can also sometimes find them in the leaves and branches of trees.



Just like soft scales, you can also find mealybugs in garden soil. They are also covered with the waxy-cottony thing they call “wooly.”

Mealybugs are pests that feed on the leaves and stems. Besides, they like to suck the plant’s living juice on the newly grown plants.

Grey-White Aphids

Grey White Aphids

Generally, aphids will live on the underside of the leaves and survive by gnawing the plant parts to tatters. 

On the other hand, gray-white aphids spend more of their time in soil and damage your plants from the roots.



Different from the previous six pests, springtails are soil bugs that are quite beneficial. They are silver or gray-bodied insects that often roam the soil of potted plants.

Springtails are not harmful to plant growth, but their uncontrolled presence can be very annoying. Therefore, you have to get rid of it too.



Isopods are not insects. They are a type of crayfish with bodies larger than springtails. These bugs are sometimes brown, silver, or gray. 

Additionally, some refer to them as pill bugs. When you touch them, isopods roll up their bodies like tiny armadillos.

Just like springtails, isopods also do not harm plants. However, if you are bothered by their presence, getting rid of them is the best way you can take.

Soil Bugs Identifications

Soil Bugs Identifications

The following are two signs to identify the presence of garden pests in soil.

  1. Soil that smells bad. Usually, this condition comes from decomposing plants caused by pests in the soil.

Check if there are earthworms around the area. If so, leave them there to eliminate the pests before they end up destroying crops in a massive scope.

  1. Your soil looks over moist and does not absorb water well. It is the second sign that you need to be aware that there have been bugs in garden soil for some time.

Root-eating insects such as aphids and mealybugs may be the leading cause of this condition.

The pests eat away at the roots and take nutrients from there, making the roots weak and unable to hold water. 

When the soil has become very moist, the chances of bugs living and breeding are greater.

Are Bugs in Garden Soil can Cause Other Diseases to Plants?

Are Bugs in Garden Soil can Cause Other Diseases to Plants

Absolutely, yes. Bugs in the soil will continue to attach to the plants from which they obtain food and nutrients. 

Even until the plant grows and replicates, the bugs stay with them until they eventually multiply and spread over a larger area.

The existence of nasty bugs that keep stealing plants’ living juice will weaken the crops and not resistant to other diseases.

7. Mulch the Garden Before and After Planting

Mulch the Garden Before and After Planting

It is essential to cover your garden using black plastic for six months before replanting. This way will help you to kill any pests, including bugs up to the eggs.

Last Thought

Sometimes people misinterpret insects and bugs. Several argue that the word “insect” is used formally, while “bug” is the informal version. 

Yet, those two terms are different. Simply put, you can say it is an insect because they have a segmented body, six legs, and antennae.

While bugs, apart from having a segmented body and antennae, they also have wings and a stylet -a straw-shaped mouth that is useful for sucking the plant’s juice.

All bugs are insects, but not all insects are bugs.

That is all about getting rid of bugs in garden soil naturally. If the pesky bugs still come, you have to consult an expert for your green as soon as possible. So, never give up on having a pest-free garden!
