Well, it may seem difficult at first but there are actually some simple steps to follow in order to make the process easier. Below we will discuss these steps and more so you can be well informed on how to deal with pesky bugs!

How to Get Rid of Bugs on Bonsai Tree

So there are ways to get rid of bugs on your bonsai tree – physical removal, chemical removal, and natural predators.

One way is by mixing neem oil with water and using an insecticidal soap mixture made at home, which will kill aphids, whiteflies or spider mites without harming the tree itself in any way!

Let’s talk about these three ways or removal methods.

1. Physical Removal of Bugs

Physical removal is the easiest way, with a simple tweezer or even with your fingers! Make sure to remove as many as possible and drop them in a bucket of soapy water made from a hand dish washing detergent to kill them. This will also prevent you from accidentally transferring any bugs from tree to tree.

2. Chemical Removal of Bugs

Also known as insecticidal soap, the chemical removal of bugs is effective for caterpillars or other chewing pests, but not so much for sucking insects like aphids and whiteflies.

It comes in different ready-to-use formulations, some are organic while some are non-organic. It also comes in concentrated formulas to be mixed with water then sprayed on the bonsai tree. When using concentrated formulas, you should wear a mask and gloves as well as protective clothing so as not to get it on your skin or in your eyes.

3. Natural Removal of Bugs

Natural predators like ladybugs or parasitic wasps will ensure your bug problem is solved for good. These bugs seek out and kill bonsai tree-damaging pests, giving you a chance to enjoy the beauty of your plant without having to worry about it falling victim at all!

Physical Methods of Bonsai Bugs Removal

There are a few physical methods that can be used to remove bonsai bugs.

  1. One is to use a vacuum cleaner to suck them up.
  2. Another is to use a spray bottle with water to squirt them off the tree.
  3. A third option is to use a brush or cloth to wipe them off.

Whichever method is used, it is important to remember that these bugs do not like light. They prefer the dark and damp areas of your home such as under furniture, in crevices, and cracks.

Chemical Methods of Bonsai Bugs Removal

Pests can be anything from pests such as insects and arachnids, to rodents. In order to have the perfect landscape or garden, it is important that all pests are removed so they don’t cause any damage. This is especially true if we are talking about bonsai trees.

If you find that there are bugs in your bonsai and they’re eating away the leaves and weakening them, you’ll notice that it’s necessary to remove these pests as soon as possible and start fighting them off. Some bugs can be fought off using organic pesticides, but some pests, such as the emerald ash borer, are best fought off using chemical pesticides.

There are many different types of chemical pesticides on the market, and choosing the right one can be a daunting task. However, once you’ve chosen the right pesticide to use, it’s important to use it properly so that you get the most out of it.

When using a chemical pesticide, always read the label and follow the directions carefully. In particular, be sure to wear the appropriate personal protective equipment (PPE), such as gloves, long pants, and a long-sleeved shirt. You should also avoid contact with the skin, eyes, and mouth.

If you’re using a solution of chemicals, be sure to mix the chemicals according to the label’s directions. If you’re using a ready-made pesticide, refer to the label for how much to use. However, regardless of what type of chemical pesticide you are using, it is important that you avoid inhaling or ingesting them.

If you’re using a chemical pesticide, it’s important to remember that it’s only a temporary fix. Once the pests are gone, you’ll need to continue to monitor your bonsai for new infestations. In addition, if you’re using a systemic pesticide, it’s important to apply it more than once, as the effects may not be long-lasting.

Cedar Oil Bug Spray for Bonsai

If you use cedar oil on your bonsai soil or leaves, it is effective at killing these pests. Cedar oil is derived from northern red cedar trees, which have insecticidal properties. It can be purchased in most garden stores or online.

  1. Mix four ounces of cedar oil to one gallon of water and mix thoroughly before spraying your bonsai with it.
  2. Be sure to follow the instructions on your bottle of cedar oil in regards to how much to use for the size of your bonsai.

To prevent infestations, it may be helpful to put sticky traps around your bonsai collection when you first bring them home.

  1. Mealybugs are attracted to the color yellow and will stick themselves to these surfaces where they cannot be seen.
  2. Once the mealworms have gathered on the sticky traps, you can vacuum them off or wipe them with a cloth or brush and place them in a jar of rubbing alcohol to kill them.

Natural Methods of Bonsai Bugs Removal

When talking about natural methods, this is all about having predators to help you with the bugs removal. This is their job and they will take care of it without any fee.

Just set them loose in your garden area, this guide will give you information about what kind of bugs that are usually found in bonsai areas and how to attract those predators into your garden.

First we have to identify the bugs that are usually found in bonsai areas.

  • Ladybug beetles, lacewing larvae, and assassin bugs are natural predators that feed on aphids, mealybugs, whiteflies, and other small garden pests. You can attract these beneficial insects to your garden by growing plants that they like to feed on.
  • Chrysanthemums, dill, fennel, Queen Anne’s lace, and yarrow are all good plants to grow if you want to attract ladybug beetles. Plant these flowers near your bonsai trees and the bugs will come to feed on the pests.
  • Lacewing larvae love to feed on aphids, so they will be happy to come and feed on the aphids found in your bonsai area. You can attract lacewings by growing flowering plants like marigolds, cosmos, coreopsis, zinnias, and sunflowers near the trees.
  • Ladybugs are not the only bugs that love to eat aphids. Assassin bugs also enjoy a good aphid snack. You can attract assassin bugs to your garden by growing plants like cosmos, tansy, and feverfew.

Once you have attracted the predators to your garden, it is important to keep them there. You can do this by providing a water source and some mulch. Predators like to drink water and they like to lay their eggs in moist soil.

Cover the ground with a two-inch layer of organic mulch and keep it damp by watering regularly. Predators will find this an ideal place for laying their eggs and staying close to food sources, so they will stick around and keep your bonsai area pest-free.

Bonsai Tree Care After Removal

After you have removed whatever method you used for killing bonsai bugs from your bonsai, it is important to clean the area where they were living.

This includes vacuuming the floor and furniture around your bonsai, as well as cleaning the leaves and branches of the tree with a damp cloth.

Be sure to dispose of the vacuum cleaner bag or canister after you are finished cleaning.

If you used a wet cloth or brush to remove bonsai bugs from your tree, you will need to rinse it with water and allow it to dry before using it again.

3. Natural Predators for Bugs on Bonsai Trees

To get rid of insects on your bonsai without having to use chemical or physical removal methods, you can use the help of their natural predators. ladybugs and praying mantises are great for getting rid of aphids, while parasitic wasps prey on spider mites and whiteflies.

Make sure to release these insects into your garden or bonsai when they’re needed and always read the instructions so that you don’t harm any other beneficial insects.

Why Do Bonsai Trees Get Bugs?

There are a few reasons why bonsai trees get bugs.

  1. One reason is that the tree may be unhealthy and lacking in nutrients, which attracts pests.
  2. Additionally, pests may be drawn to the tree because of its location or the climate conditions in the area.
  3. Finally, if the tree is not properly cared for, it can become susceptible to insects.

Bugs are attracted to bonsai trees that are under stress, have weak immune systems, or are not properly cared for. If the tree is too dry or too wet, it can become vulnerable to certain bugs that would not normally be able to infest a healthy tree. And, if the tree has any wounds on its bark, that can also be an entry point for pests.

Expected Bonsai Bugs

Bonsai are very popular house-plants, which are valued for their aesthetic beauty. However, the plants are fragile and demand special care. Frequently bonsai attract various pests that attack them in any period of plant’s development. Two essential requirements should be followed while combating these insects: quick reaction to pest appearance on your bonsai, and regular preventive maintenance. So, what are the prominent bugs that may infest bonsai?


These pests are small, soft-bodied, and pear-shaped. They may be green, black, or pink in color. Aphids feed on juices from leaves and stems of plants by piercing the surface with their sucking mouthparts. Heavy infestation can distort and stunt the plant growth, and may cause leaves to yellow and fall off.

Prevention and Treatment: To get rid of aphids, use a strong jet of water from the hose to knock them off the plants. You can also use insecticidal soap or horticultural oil. Be sure to read and follow the instructions on the product label.

Scale Insects

Scale insects are small slow moving plant parasites that suck plant juices using their long needle-like mouthparts. Brownish or black lumps of up to 1mm large can be noticed on branches and leaves of infested plants. These insects can cause extensive damage to the plant, weakening it and leading to death in severe cases.

Prevention and Treatment: Scale insects are difficult to get rid of using organic methods. The most effective way to control these pests is to use chemical pesticides. However, before spraying the trees with pesticides, it is important to identify the particular species of scale involved, as different pesticides are effective against different types of scales.

Spider Mites

Spider Mites are another common type of bonsai pests that can be identified by their small size and eight legs. These pests feed on leaf tissues, causing damage by sucking sap. This results in yellowing and rolling up of leaves. Sometimes webbing is visible between the leaves, which means mites are present in large numbers.

Prevention and Treatment: Infested plants should be moved to a warm dry place for at least two weeks in order to kill the larvae and adults. Dormant oil spray may be used against mites; however it should be remembered that oil may suffocate the plants. Organic pesticide derived from Neem tree seeds can also be used for controlling mites on bonsai.

White Flies

White flies are a common type of greenhouse pests, which hide under leaves and suck plant juices using their needle-like mouthparts. Damage from white fly feeding is not easily visible, but the presence of these pests is indicated by the presence of honeydew on leaves. This sticky substance is secreted by the white fly when it feeds and is a medium for growth of black sooty mold.

Prevention and Treatment: Sanitation is essential to control white flies in greenhouses. All infested plants should be removed and their pots thoroughly cleaned before reusing. Insecticidal soap spray can be used to control white flies, while neem oil is effective against eggs and young stages of these insects.


Mealybugs are small soft-bodied insects that look like white cotton balls. They attach themselves to leaves, stems and fruits of plants and suck plant juices. Infested plants may show stunted growth, leaf drop, and distorted fruit.

Prevention and Treatment: Mealybugs can be controlled by using a jet of water from the hose, or by using a systemic insecticide. Be sure to read and follow the instructions on the product label.


Weevils are another common type of bonsai garden pests that attack seedlings, saplings and growing tips of plants. These pests feed on leaves, causing curling and yellowing of leaves. Adult weevils are small brownish beetles with curved snouts.

Prevention and Treatment: Removal of the infested parts is an effective method for controlling these pests using organic pesticides. Avoid using dusty mulch around plants as this can damage plant tissues and provide hiding places to weeds that harbor weevils.

So, these are some of the common pests that can infest bonsai plants. By following proper prevention and treatment measures, you can keep your bonsai healthy and free of pests.

Fungus Gnats

Fungus gnats are a common problem for bonsai gardeners. These small black flies with long legs and clear wings lay eggs in soil surrounding the roots of plants. The larvae feed on organic debris present in moist potting mix, leading to damage to plant tissues through decomposition.

Prevention and Treatment: To get rid of fungus gnats, it is important to remove dead leaves and other plant debris from the pot. If adult fungus gnats are seen flying around bonsai plants, they can be killed with soapy water or neem oil sprays. Larvae of these pests can also be controlled by adding beneficial soil bacteria called Bacillus thuringiensis into the potting mix.

So, these are some of the common pests that can infest bonsai plants. By following proper prevention and treatment measures, you can keep your bonsai healthy and free of pests. Some of the most effective methods for controlling these pests include using chemical pesticides, removing infested parts of the plant, and using beneficial insects for controlling harmful ones.

Tips for Caring of Your Bonsai After Bug Attacks

Most people would view a bonsai that’s been ravaged by bugs as a lost cause. It probably is, but there are steps you can take beforehand and afterwards to minimize the damage and perhaps save a beloved tree.

Let’s start with the endgame: what do you do after you know your tree is infested?

1. First, remove the bonsai from its pot. This lets you see how bad things are and identify any larvae or adults that have managed to escape notice until now. Once you’ve sprayed them with soapy water for good measure, put it back in the pot after using a small brush to dust the roots with sulfur powder.

2. If you see larvae, there’s a chance they might destroy your tree even if you manage to kill the adults that laid them in the first place. You can set traps using sticky tape or cotton balls that have been soaked in sugar water (dunk one in a cup of water and let it soak up the liquid), but these won’t be 100% effective.

3. Cut away any parts of the tree that have visible damage, including leaves with larvae on them if you can do so without harming healthy branches. If it’s too hard to see what’s going on in your tree when you’re doing this, put it back in its pot and wait until the next time you can inspect it closely.

4. Prune back any branches that are too weak to support the tree’s weight, especially if they’re near the top. This will help prevent the tree from breaking and make it easier to care for in the long run.

5. Finally, give your bonsai a thorough spraying with insecticide; use one that contains Malathion (a common ingredient in over-the-counter sprays) or carbaryl (Sevin); you can buy these at any garden center. If the infestation was particularly bad, you might need to repeat this step after a few days to make sure all the bugs are gone.

After your bonsai has recovered:

After your bonsai has recovered, it’s time to do some preventive maintenance.

1. Replace the soil around the roots with fresh stuff, and make sure it’s loose enough for adequate drainage; if you were too aggressive when removing the old potting mix, this will be easy to do.

2. Trim away any leaves that show signs of stress. Some species may only lose part of their leaves, while others may drop them all. Don’t worry about it-this is normal for stressed plants.

3. Finally, keep an eye on your tree for any signs of renewed infestation; these can occur months after the initial attack if you’re unlucky . If you see more bugs after a week or so, give it a second spraying with insecticide.

Caring for your bonsai after a bug infestation can seem like a daunting task, but hopefully these tips will make it a little bit easier. With a little patience and some TLC, your tree should be back to its old self in no time.

More Information On Bonsai Bugs

If you’re seeing any of the following signs, it’s likely that your bonsai has bugs:

  • Trees are wilting or have yellowing leaves
  • There is a sticky film on the leaves or trunk
  • The bark is splitting or peeling
  • Small black spots are appearing on the leaves
  • White cottony growth is present on the branches or leaves

If you suspect that your bonsai has bugs, it’s best to take action right away. Insects can damage and even kill a bonsai, so it’s important to get rid of the bugs as soon as possible. There are a few things you can do to get rid of the bugs and prevent your bonsai from becoming re-infested.

Removing Bugs From Tree Branches

If you’re seeing small, black spots on the leaves of your bonsai, it’s likely that they have a common pest known as twig aphids. These pests can be removed from the branches by wiping them with a cloth that’s been dipped in rubbing alcohol.

Removing Bugs From the Trunk

If you’re seeing a sticky film or small white cottony growth on the trunk of your bonsai, it’s likely that they have an insect known as scale. To remove these bugs, use a cotton swab soaked in rubbing alcohol. Be sure to wipe down the entire trunk, as well as any exposed roots.

Preventing a Reinfestation

If you’ve successfully removed all of the bugs from your bonsai and want to prevent a reinfestation, it’s best to place them in a shady location. Insects are more likely to attack plants that have been exposed to direct sunlight, so it’s important to keep them out of direct light. Also, be sure to clean the entire bonsai at least once a month because bugs can easily hide in spots where you can’t see them.
