Causes of a sticky bird of paradise plant
One day while pruning my bird of paradise plant, I noticed its leaves felt sticky.
Upon inspection, I noticed some pests feeding on its leaves.
The honeydew excreted by the pests is the main reason behind the stickiness.
So, I started finding ways to eliminate these pests from my plant without wasting more time.
After that, it didn’t take me long to remove pests from my plant and help it recover.
Since I have faced this problem, I want to help you fix your bird of paradise if its leaves have become sticky.
The leaves of a pest-infested plant will look old, sticky, limp, and discolored.
If your bird of paradise plant has a pest infestation, you must take immediate action to save it.
Let us briefly discuss how pests damage your bird of paradise plant and what measures you can take to save it from further damage.
1. Pest infestation
Pests are nightmares for any houseplant.
Common pests that can infest the bird of paradise plant are mealybugs, spider mites, aphids, scales, whiteflies, etc.
My bird of paradise plant has a mealybug infestation.
The pests feed on the plant’s sap, making it weak and vulnerable, and they can also kill the plant if they remain unnoticed.
The sap is the nutrient-rich fluid that gives the plant strength, energy, and growing power.
When the pests suck sap, the plant loses its strength and energy and weakens.
After feeding on the plant, the pests excrete a sticky substance called honeydew.
The sap has sugar content, due to which the honeydew is sticky.
Various other insects, like ants, get attracted to the honeydew causing further damage to the plant.
You may find mold and fungal growth, causing more injuries and damage to the plant.
If you find pests, please take the necessary measures to remove them from your plant and wipe off the honeydew to avoid future infestations.
Identifying pests that may cause sticky residue on your bird of paradise plant
Various pests can cause sticky residue on your bird of paradise plant.
Let us now understand each of the pests in detail.
Mealybugs are small, soft-bodied, wingless insects that look like white cottony masses on the plant parts.
They have long piercing mouthparts called stylets, which they use to suck sap from the plant tissues.
They spread very quickly and can cause leaf yellowing and curling.
Their feeding is accompanied by honeydew which makes leaves sticky and encourages the growth of sticky mold.
Aphids are tiny, soft creatures with slender mouthparts that pierce leaves, stems, and other tender parts to suck fluid from them.
They stay on the lower part of the leaves, and their attack can cause the leaves to turn curly, wilted, and damaged.
Aphids multiply very quickly, so controlling them is essential before they start reproduction.
They excrete honeydew after feeding on the plant, which encourages mold growth and fungal diseases like powdery mildew.
The whiteflies are tiny, soft-bodied winged insects that feed on the underside of leaves.
They use their piercing mouthparts to suck plant juices and produce a sticky substance called honeydew.
The excretion of honeydew can cause fungal diseases in the plant, like sooty mold.
The plant becomes extremely weak and fails to carry photosynthesis if there is a heavy infestation.
The leaves will wilt, turns yellow, growth gets stunted, and they eventually wither and fall off.
4. Spider mites
The spider mites are tiny, reddish brown, oval-shaped insects that mostly live in colonies on the underside of leaves.
They form a web structure on the leaves, which isn’t visible to the naked eye.
However, if the bottom side of the leaves is sticky, it’s because of spider mites.
They feed on the plant by piercing the leaf tissues and sucking sap.
The continuous feeding will cause the plant leaves to turn yellow, dry, and drop off.
The scales are small insects having a body covered with a protective waxy shell.
These sap-sucking insects attach to plants’ leaves, branches, and twigs.
They use their hair-like mouthparts to feed on the plant tissue and suck out the sap, damaging the plant.
The scales are oddly shaped insects that resemble small yellow or brown bumps on the stems and leaves.
A heavy infestation will lead to poor growth, reduced vigor, and yellow leaves of your plant.
Remedies for getting rid of sticky residue on a bird of paradise plant
Cleaning your bird of paradise plant and removing as many pests as possible is essential for removing the sticky residue.
The severity of treatment depends on the extent of pest infestation on your plant.

1. Mealybugs treatment
Follow the below steps to treat mealybugs in your bird of paradise plant.
- Firstly you must isolate your bird of paradise to prevent the pests from spreading to other houseplants.

- You can also use insecticidal soap to remove pests from your plant.
2. Guttation in bird of paradise plants
The bird of paradise plant can sometimes release a sticky substance from their leaves.
This situation will occur when the plant is highly saturated and can’t absorb water anymore.
In that case, the plant releases excess water from its leaves.
This process of eliminating excess moisture is called transpiration.
The plant sometimes releases sap and water during transpiration, making the leaves sticky.
This situation is known as guttation.
If you discover the leaves sticky but don’t find any pests and notice watery crystals, it is because of guttation.
Guttation is natural and doesn’t harm plants.
But whenever you find sticky leaves because of guttation, clean them as they can lead to various pests and fungal diseases in the plant.
Is too much guttation dangerous for a bird of paradise plant?
Guttation is a natural process of removing the extra water from the plants through their leaves.
However, excess of anything is harmful to the plants.
If your plants have higher guttation, it might be because you are overwatering the soil.
The plant will lose all its essential nutrients if guttation is high.
The leaves of your bird of paradise plant will get burn marks if there is too much guttation.
To prevent excessive guttation in your plant, you can follow the following tips given below.
- Avoid overwatering your plant. When you overwater, plants will fail to absorb the excess water and will transpire more, increasing the guttation rate.
- Avoid keeping your plant in a highly humid region and maintain the ideal humidity range. Ensure the plant is getting sufficient air and light.
- Avoid over-fertilizing your bird of paradise plant. When you over-fertilize your plant, there will be salt and mineral build-up in the soil, which can result in leaf burns and increased guttation.
- Avoid tap water and use only distilled or filtered water to water your plant. Tap water has minerals like fluorine and chlorine that can increase the guttation rate.
How to clean sticky residues off a bird of paradise plant?
The honeydew excreted by pests is the primary reason for the sticky leaves in your bird of paradise plant.
So, cleaning the plant is vital for removing the sticky substance and repelling pests.
Below I mentioned some ways which you can follow to keep your plant leaves clean.
- Mix 1 teaspoon of liquid dish wash soap or detergent in 1 quart of water.
- Dip a cotton ball in this mixture and wipe off the leaves.
- Clean both sides of the leaves nicely, as pests can hide anywhere.
- I also use isopropyl alcohol to clean my plant’s leaves, which cleans well.
Preventing sticky residue on your bird of paradise plants
You can prevent the sticky residue on your bird of paradise plant by following the tips below.
- Grow your bird of paradise plant in a place that provides bright indirect light with a few hours of direct light. Avoid keeping the plant in a low-light area, as it can become more prone to pests and fungal attacks.
- Keep the soil moist but not soggy. Consistently damp soil can become the breeding ground for pests.
- Keep your bird of paradise plant in a well-ventilated area to ensure plenty of airflow around it.
- Check your plant regularly for any pest infestations.
