In this article, we’ll cover everything you need to know about identifying, preventing, and treating whitefly infestations on hibiscus. Whether you prefer natural remedies or chemical insecticides, we’ve covered you with step-by-step instructions and tips for success. So let’s dive in and banish those pesky whiteflies for good!
Identifying Whiteflies on Hibiscus
Whiteflies are tiny, sap-sucking insects that belong to the family Aleyrodidae. They are typically found on the undersides of hibiscus leaves, feeding on the plant’s sap and excreting a sticky, sugary substance known as honeydew.
Adult whiteflies are small, moth-like insects about 1/16 to 1/8 inch long. They have white wings and yellowish bodies. When disturbed, they will flutter around the plant and quickly return to their original location.
Whitefly eggs are tiny and difficult to see with the naked eye. They are usually laid on the underside of the leaves in clusters of 20 to 30. Once the eggs hatch, the immature whiteflies, known as nymphs, will begin feeding on the sap of the hibiscus plant.
If you suspect that your hibiscus plant has a whitefly infestation, carefully inspect the undersides of the leaves for signs of adult whiteflies, nymphs, and eggs. You may also notice sticky honeydew on the leaves or a black, sooty mold that grows on the honeydew.
The Damage Whiteflies Cause
Whiteflies can cause significant damage to hibiscus plants, both by feeding on the plant’s sap and by transmitting plant viruses. Some of the most common symptoms of whitefly damage on hibiscus plants include:
- Stunted Growth: Whiteflies feed on the sap of the hibiscus plant, which can cause the plant to grow more slowly than it normally would. This can result in stunted growth and smaller overall plant size.
- Yellowing Leaves: As whiteflies continue to feed on the hibiscus plant, they can cause the leaves to turn yellow or brown. This can be especially noticeable on newer leaves.
- Leaf Drop: In severe cases of whitefly infestation, the hibiscus plant may begin to drop its leaves prematurely. This can indicate that the plant is stressed and lacking nutrients.
- Sooty Mold: Whiteflies excrete a sticky, sugary substance called honeydew. This can attract other insects and lead to the growth of a black, sooty mold on the leaves of the hibiscus plant.
- Plant Virus Transmission: Some species of whiteflies are known to transmit plant viruses, which can cause even more damage to hibiscus plants.
If left unchecked, whitefly infestations can severely damage hibiscus plants and even lead to their death. That’s why it’s important to take action as soon as you notice any signs of whiteflies on your hibiscus plant.
- Targets and kills aphids, beetles (Leaf-feeding), caterpillars (Leaf-feeding), crickets, earwigs, lace bugs, leafhoppers, mealybugs, mites, plant bugs, scale crawlers, thrips and whiteflies

Natural Remedies for Whiteflies
If you’re looking for a natural way to control whiteflies on your hibiscus plant, there are several remedies you can try:
Introduce Natural Predators:
Ladybugs and lacewings are natural predators of whiteflies and can help to control their population. You can purchase these insects at many garden supply stores and release them onto your hibiscus plant.
Use Neem Oil:
Neem oil is a natural insecticide that can help to control whiteflies on hibiscus plants. Mix one tablespoon of neem oil with one teaspoon of dish soap and one quart of water. Spray the mixture onto the undersides of the hibiscus leaves, making sure to cover all areas. Repeat every week until the whitefly population is under control.
Spray with Soapy Water:
Soapy water can be an effective way to control whiteflies on hibiscus plants. Mix one tablespoon of dish soap with one quart of water and spray the mixture onto the undersides of the hibiscus leaves. This will suffocate the whiteflies and prevent them from feeding on the plant. Repeat every few days until the whitefly population is under control.
Use Sticky Traps:
Sticky traps are another natural way to control whiteflies on hibiscus plants. Hang yellow sticky traps near the hibiscus plant to attract and trap the whiteflies. You can purchase these traps at many garden supply stores.
Use Reflective Mulch:
Reflective mulch can be placed around the base of your hibiscus plant to reflect sunlight onto the undersides of the leaves, making it less attractive for whiteflies to lay their eggs.
When applying natural remedies to remove whiteflies on your hibiscus plant, following the instructions carefully and being patient is important. Natural remedies may take longer to show results than chemical pesticides, but they can be just as effective in the long run.
When applying natural remedies to control whiteflies on hibiscus plants, it’s important to follow these steps:
- Test the remedy on a small hibiscus plant area first to ensure it doesn’t cause any damage.
- Apply the remedy in the early morning or late afternoon when the hibiscus plant is not in direct sunlight.
- Make sure to cover all areas of the hibiscus plant, especially the leaves’ undersides where whiteflies congregate.
- Repeat the treatment as necessary until the whitefly population is under control.
Chemical Treatments for Whiteflies
If natural remedies don’t effectively control whiteflies on your hibiscus plant, consider using chemical treatments. Here are some of the most common chemical treatments for whiteflies on hibiscus:
- Insecticidal Soap: Insecticidal soap is a low-toxicity pesticide that effectively controls whiteflies on hibiscus plants. To use insecticidal soap, dilute the solution according to the manufacturer’s instructions and spray it on the affected leaves, covering both the tops and undersides of the leaves.
- Neonicotinoids: Neonicotinoids are a type of systemic pesticide that can be applied to the soil around the base of the hibiscus plant. The pesticide is absorbed by the roots and distributed throughout the plant, effectively controlling whiteflies and other pests.
- Pyrethroids: Pyrethroids are a type of synthetic pesticide that can effectively control whiteflies on hibiscus plants. Pyrethroids should be applied to the affected leaves according to the manufacturer’s instructions, covering both the leaves’ tops and undersides.
When applying chemical treatments to remove whiteflies on your hibiscus plant, it’s important to wear protective clothing and follow the instructions carefully. Be sure to apply the pesticide only as directed, and avoid overuse, as this can lead to pesticide resistance. Additionally, always store pesticides out of reach of children and pets.
