Is your plumeria suffering from an aphid infestation? Unfortunately aphids are a really common problem. When I first brought my plumeria out for the season this year I had them in the sunniest part of the patio. What could go wrong? Well, they were a little too close to a row of crepe myrtle trees, which are notorious for aphid infestations. Every one of my over 20 plumeria got aphids. Since you are here, it’s probably a safe bet that you have aphids on plumeria too. In this article, we will go over how to identify aphids, how aphids damage plants, how get of aphids and how to prevent aphid infestations.

What do Aphids Look Like?
Aphids are a common garden pest problem. Aphids are tiny insects that can be found in gardens and on plants. They are very small and range in size from about 1 to 3 millimeters long. They come in different colors, such as green, yellow, brown, or black. Some aphids have wings, while others do not. Their bodies are shaped like tiny ovals or pears. When you look closely, you might notice that aphids have long, thin antennae sticking out from their heads.
One of the distinctive features of aphids is their soft bodies. They have a waxy or sticky texture, making them appear shiny. This characteristic can sometimes make them look like they’re covered in a sugary substance, almost like a tiny candy.
Because aphids feed on plant sap, they often cluster together on leaves, stems, or flowers. You might see them in groups, especially on new, tender growth. Sometimes, you might even notice that aphids leave behind a sticky residue called honeydew, which can attract other insects like ants which can cause black mold or sooty mold to grow on plants. This can lead to other problems like fungal infections,
Remember, even though aphids might be small and seem harmless, they can reproduce quickly and cause damage to plants if left unchecked. It’s important to keep an eye out for these little insects and take action quickly to manage their population to keep your plants healthy and thriving.
What does Aphid Damage Look Like?
Aphid damage on plumeria can cause the following:
- Wilting
- Curled or puckered leaves
- Yellow leaves
- Browning leaves
- Stunted growth
If you suspect you have aphids on a plant or two, move the plant away from your other plants as aphids will spread from plant to plant quickly.
How do you get rid of aphids on Plumeria?
To get rid of aphids on plumeria, you can use a gentle, organic approach. Here’s what you can do:
- Blast them away: Use a hose to spray a strong stream of water on the infested plants. This will knock off the aphids and help control their population.
- Invite beneficial insects: Ladybugs and lacewings are natural predators of aphids. Plant flowers like marigolds and alyssums to attract these helpful insects to your garden.
- Homemade insecticidal soap: Mix a teaspoon of mild liquid soap with a quart of water. Spray this solution on the affected plants to suffocate and repel the aphids. Make sure to spray the entire plant, including both sides of the leaves the stems and the trunk,
- Remove infested leaves: If the infestation is severe, carefully remove the affected leaves and dispose of them in a sealed bag or burn them.
Remember, it’s important to be patient and consistent with these methods. You will need to repeat these methods every few days for a couple of weeks to make sure all of the aphids and their eggs are killed. By taking these steps, you can keep your plants healthy and aphid-free!
Another option is to treat the aphids with an insecticide. We like this Garden Safe Spray it’s made with botanical insecticides.
How to prevent Aphid Infestations
Preventing aphid infestations involves a combination of cultural, biological, and, if necessary, chemical methods. Here are several strategies to prevent these pests:
- Plant Companion Plants: Certain plants repel aphids. Examples include marigolds, chives, garlic, and nasturtiums. Planting them near aphid-prone plants can act as a deterrent.
- Attract Beneficial Insects: Ladybugs, lacewings, and parasitic wasps feed on aphids. Encouraging these beneficial insects can help keep aphid populations in check. You can attract them with flowering plants like dill, fennel, and yarrow.
- Monitor Plants Regularly: Regularly check the undersides of young leaves and stems for signs of aphids. Early detection makes them easier to manage.
- Water Spray: A strong jet of water from a hose can knock aphids off plants. This method is most effective in the early stages of infestation.
- Encourage Strong Plant Growth: Healthy plants are less susceptible to aphid attacks. Ensure your plants get the right amount of water, nutrients, and are planted in the appropriate soil and light conditions.
- Natural Sprays: Soap and water or neem oil sprays can deter aphids without harming beneficial insects. Ensure to spray both the top and underside of leaves.
- Avoid Over-Fertilizing: Aphids are particularly attracted to plants with soft, new growth. Over-fertilizing, especially with high-nitrogen fertilizers, can produce this kind of growth.
- Reflective Mulches: Aluminum foil or reflective plastic mulches can disorient aphids and prevent them from landing on plants.
- Row Covers: Physical barriers, like floating row covers, can prevent aphids from accessing plants.
- Avoid Chemical Pesticides: While they can be effective against aphids, chemical pesticides can also kill beneficial insects and might make the problem worse in the long run.
- Ant Control: Ants farm aphids for their honeydew. Controlling ant populations can indirectly reduce aphid numbers.

FAQ – Aphids on Plumeria
Common signs include curled or yellowed leaves, stunted growth, and a sticky substance called honeydew on the plant. You may also notice tiny pests on the undersides of the leaves or stems.
Plant companion plants like marigolds or chives nearby, encourage beneficial insects like ladybugs, and regularly inspect and rinse your plumeria with water to knock off early infestations.
Yes, aphids suck sap from plumeria, weakening the plant and making it susceptible to diseases. They can also transfer viruses between plants.
While chemical pesticides can kill aphids, they may also harm beneficial insects and might not be ideal for long-term control. It’s better to start with natural remedies and use chemicals as a last resort.
Regular monitoring, ideally once a week, is recommended, especially during the growing season or when you notice any signs of plant stress.
