Philodendrons develop various problems if they get infested with pests. Pests can cause yellow or brown leaves, wilting, discoloration, and distorted growth if you don’t identify the problem on time. But how do pests reach your philodendron plant? How can you get rid of the bugs in your philodendron?
Philodendron will attract bugs if it is living under unfavorable conditions. To get rid of bugs, you need to separate the plant from other houseplants and spray some diluted neem oil solution, insecticidal soap, or any chemical pesticide. Wiping the leaves with rubbing alcohol also works.
A healthy philodendron will never attract bugs. But if you don’t provide the right living conditions, the pests will get attracted to your philodendron.
Giving your philodendron excess water along with high humidity and poor ventilation will create the perfect environment where the pests will thrive.
However, if you can detect the pests early, there’s nothing to worry about as you can easily remove them.
The first step to eliminate the bug is identification. So, let’s first learn to identify the bugs and then discuss 11 different solutions to get rid of them.

Common bugs in philodendrons
If your philodendron loses its luster and looks dull along with distorted foliage, you must thoroughly inspect the plant. There might be pest infestation in your philodendron. Let’s take a look at few common bugs that can attack your philodendron.
Aphids are tiny pests but can create big problems in your philodendron.
Aphids are oval-shaped and 2 mm in size. Their colors can vary from green, yellow, red, brown, or black. These are found in groups, and they attack the plant’s new growth or reside underneath the leaves of the plant, so it becomes hard to detect them.
Aphids secrete a sticky liquid on leaves and stem called honeydew. They feed on the sap of the philodendron. A sign that your philodendron has an aphid infestation is that you’ll notice tiny white flakes on the plant’s stems and leaves.
Some other signs of an aphid infestation include yellow and deformed leaves. Aphids affect the growth of your philodendron and can make the plant look deformed.
Spider mites are tiny pests that look like young spiders. You may notice spider mites in different colors on your philodendron.
It is hard to identify the spider mites as they are very tiny, but one easy way of detecting them is when you notice thin and silky web-like structures all over the plant. The spider mites pierce the leaves and cause discoloration or yellow leaves.
You will be able to spot spider mites if you use a magnifying glass. These bugs are found everywhere, such as roots, leaves, soil, and stems of the philodendron.
You must get rid of these pests as soon as possible as they populate fast and affect all parts of the plant.
You will also notice a change in your philodendron’s appearance along with discolored leaves.
If you notice a shiny glazing coating on your philodendron, your philodendron might be attacked by scales.
There are two types of scales such as soft scales and armored scales. These resemble tiny bumps that come in brown, gray, or black.
Like the names suggest, armored scales have a hardcover that can save them from chemical pesticides and soft scales have a wax coating that can be difficult to get rid of.
Scales secrete a sticky liquid which is not easy to deal with.
Scales can pierce through the leaves, branches, and stems of your philodendron and feed on the plant sap, making it weak.
You will notice symptoms like yellow leaves, brown spots on the leaves, wilting and stunted growth due to scale attack on your philodendron.

Mealybugs are tiny fluffy pests that resemble cotton and are often mistaken as fungus or mildew because of their appearance.
Mealybugs are oval-shaped and have different colors, such as brown or cream. The mealybugs suck on the philodendron’s sap and take all the nutrients out of the plant.
These pests can mostly be found on the undersides of the leaves of your philodendron.
If your philodendron has deformed and yellow leaves, leaf drop, or stunted growth, your plant might have a mealybug infestation.
If you notice a group of small flies around your philodendron plant, these are most probably gnats that are tiny flies.
It is easier to identify the fungus gnats as they remain in groups and are dark-colored flies. These develop in the soil, so the flies will come out of the plant with a buzzing sound if you shake up the philodendron.
Fungus gnats not only affect the philodendron but also wander around your house, especially in the kitchen, windows, or living areas.
The larvae attack the roots and damage them by creating wounds and feeding on the soil fungi.
How do you get rid of bugs on philodendrons?
You should try to eliminate the bugs from your philodendron as soon as possible as these pests will not let your plant remain healthy. These pests populate very fast and will cover the whole plant in no time.
First, you need to isolate your philodendron so that the pests cannot spread to the other houseplants of your house. You must prune the damaged leaves and branches but don’t prune too much as that will shock the plant.
There are different ways to control these pests. While you can easily opt for chemical pesticides, we recommend the natural and organic ways that we will discuss in a while.
We recommend organic ways as those will not cause any harm to your plant and the environment.
Try to opt for pesticides that are meant for the houseplants only.
Try to eliminate as many pests as possible by washing the plant with running water. This might not eliminate all the pests but will get rid of quite a lot of them.
Do not overwater and ensure that the water gets drained out from the soil thoroughly. If the water doesn’t get drenched, the soil will remain moist and encourage bacteria or other diseases.
You can also handpick the pests that are visible and not getting washed by the water. Remember to use gloves while doing this.
Water the philodendron during the day when the sun is out so that the soil can get dry. If you keep doing this for a few days, you will notice an improvement in your philodendron’s health.

Insecticidal soap is nontoxic for your philodendron, so it is an excellent way of eliminating pests.
People don’t use insecticidal soap much after the arrival of chemical pesticides on the market. Now, people are concerned about the health of their plants and try to opt for organic options, so the insecticidal soaps are coming back to the market again.
You can make your insecticide soap with the following steps:
- Take one tablespoon liquid soap
- Take 4 cups of water
- Mix the liquid soap with water and pour the solution into a spray bottle
- Shake the mixture well
- Don’t make the mixture too strong, as it can dehydrate the philodendron
Spray this solution once a week if the pest infestation is not severe. Spray the solution when the temperature levels are low, and the light is medium.
If the pest infestation is severe, spray this mix on your philodendron after every few days. If the pest infestation is medium, you can spray the solution directly on the pests.
This solution will affect the pests by penetrating their membranes and suffocating them.
You can get rid of the sticky pests by using rubbing alcohol on them.
You must make a mixture using 1 part alcohol with three parts water and apply this directly to the pests. This will help to get rid of the pests if the infestation is severe.

A great organic way of treating philodendrons is using horticulture oils. You need to apply the soil after every few days to control the pests.
This oil suffocates the pests by stopping their feeding or clogging their breathing cycle. The horticulture oil is light and will not cause any damage to the plant as it will evaporate quickly.
The horticulture oils work better on bugs with soft bodies.
Don’t spray horticulture oils when the sunlight is too intense or the temperature is too high, as it will stress the plant. You should not spray horticulture oils when the temperature is low either.
You should avoid fertilizing your philodendron when it is affected by pests. The humidity level must not be very high as that will not let the oil evaporate naturally. This will be harmful to the philodendron.
Use light oil or oils labeled summer instead of dormant oils. Light oil will work better on soft-bodied bugs.

- ORGANIC GARDENING: Natria Neem Oil can be used up to the day of harv
You can extract neem oil from the neem seeds, and these are very effective in getting rid of pests. Neem oil is slightly toxic and works excellent if you want to eliminate the pests.
Neem oil damages the hormones and brain of the bugs, due to which they fail to eat or mate. This leads to the demise of the bugs.
You must spray neem oil all over the plant and make sure that the oil reaches the undersides of the leaves as the pests reside more over there.
You can make a neem oil solution by mixing:
- 1½ teaspoon of neem oil
- 1 teaspoon of dish soap
- 1 liter of water
Spray it all over the philodendron. Keep doing this for a few days.
Don’t forget to wear a mask to avoid any headache or irritation. For better results, you can use cold-pressed neem oil.

You can use pyrethrin as a gentle botanical treatment against pests. You can spray this on your philodendron to paralyze the bugs and knock over the flying insects.
You can spray this or use the powder to dust once every few days. However, it is best to use this with another pesticide to eliminate the pests permanently.
Ryania is a dried stem extract that comes in powder form and is combined with other chemicals.
You can dust this on your philodendron to control the pests. However, keep it away from your dogs and fish as it is toxic for them.

- Simply set the indoor insect trap near fruit, trash bins, or plants

To control the flying pests, you can use sticky traps.
You can make a trap by applying petroleum jelly on yellow cardboard, or you can buy one.
This trap will help you eliminate the flying bugs, but this is not the best method as it will not eradicate the insects.
You can use this to eliminate the pests as it cracks the bugs’ bodies, stops their movement, dehydrates, and kills them ultimately.
However, this must not be accessed by honey bees, butterflies, or other pollinators as it is poisonous for them.
