Signs of Aphids on Hibiscus
If you’ve noticed that some of your hibiscus leaves are curling and that the stems of your hibiscus plant have tiny greenish or black bugs, you probably have an aphid infestation on your hands. Aphids are tiny, pear-shaped insects that measure approximately 1/8 of an inch in length. Their mouthparts are designed for piercing and sucking, which is why they cause problems for hibiscus and most annual plants.
Some of the signs of aphids on hibiscus include:
- Small greenish bugs may be seen on stems, leaves, and shoots.
- Curled leaves from aphid feeding or burrowing into stems and roots.
- Black spots at the end of a leaf where an aphid has been chewing away at your plant’s fluids.
- Tiny pinholes in new growth due to their saliva injecting chemicals as part of their effort to extract plant sap.
- Sticky areas on the plant.
- Yellowing and falling leaves.
- Flower buds that fail to open.
- Stunted shoots.

How to Get Rid of Aphids on Hibiscus
The answer to this question is not straightforward, but there are some rules. To effectively eliminate aphids from your hibiscus, consider the following methods:
Treat them early
The most effective method to kill aphids on hibiscus permanently is to start treating them early before the insects develop and do harm to the plant. The early infestation is often dealt with by a strong spray of water.
Use a strong stream of water to wash away the aphids
Aphids may be dealt with at an early stage when there are just a few of them on your hibiscus plant. They’ll be dislodged from the leaves, stems, and buds of your hibiscus flower by a strong dousing of water. Some of the aphids will be killed by a blast of water at high pressure, while others that fall off alive will starve to death.
Imidacloprid is known to kill aphids by getting them through their tracheal tubes once they have ingested the fluid from the plant sap that has been treated with it. The aphid’s body will dry up and fall from your hibiscus plants, thereby removing the infestation.
Spray a soap solution on the aphids
An aphid soap spray can be made by mixing some liquid dishwashing soap in water. The aphids will die on contact with this solution since it breaks down their waxy coating which they need to survive dry conditions outside the hibiscus plants.
Spray an insecticide on the aphids
This aphid control method should only be used if other methods don’t work, or when aphids have successfully spread from the leaves to your hibiscus buds and flowers.
Apply neem oil to aphids
Neem oil is an organic aphid control solution that can be used to kill all stages of aphids on hibiscus plants. It contains azadirachtin which causes insects’ larvae, nymphs, and adults to dry out and die once ingested by them.
Prevention is better than cure
To get rid of aphids entirely, or to keep the few that exist from reproducing and causing significant harm to your hibiscus plants, follow these steps:
- Prune the afflicted leaves.
- Avoid using fertilizers.
