Orange aphids on mandevilla are a pretty common sight on those lovely green vines. In addition, part of the answer to the reason lies in color — aphids are naturally drawn to green. But, reasons for why they are here stretch beyond this simple explanation.
Find out why and how to get rid of those pesky sap suckers, as you read this article.

Why Are There Orange Aphids on Your Mandevilla?
There are orange aphids on your mandevilla because the plant is exceptionally nutritious to them, and it can also be because the plant has weakened and they are coming to the debris. In addition, it can happen because they are attracted to the color, and lastly, due to environmental factors.
– The Plant Is Nutritious
These tiny creatures have a keen sense of detecting sources of sap, which serves as their primary source of nutrition. Aphids leave behind a sticky substance called honeydew, which attracts predators like ants and can lead to the growth of sooty mold fungus, which is one of the surefire ways to identify them.
One remarkable thing about aphids is their rapid reproduction. In just one season, they can produce many generations — exactly why it’s crucial to address an aphid problem as soon as it’s spotted. This is because as they find their source of food, they will be thrilled to attack and start growing in a more significant number, as they love to gather in colonies and have a particular fondness for sucking the juices out of fresh new growth on plants like Mandevilla.
Mandevilla plants, with their succulent stems and foliage, offer a succulent treat for aphids, and this is why they will feel safe and grounded when they find their food source. These insects have specialized mouths that allow them to pierce the plant tissues and extract the sap, which contains vital nutrients. The sap acts as a nourishing elixir for aphids, fueling their growth and reproduction.
– Attacking the Weakened Plant
When a Mandevilla is struggling due to insufficient sunlight, inadequate nutrients, or water, it becomes more vulnerable to aphid infestations. It’s an example of opportunism at its worst. Once the aphids identify a vulnerable Mandevilla plant, they take advantage of the situation. The weakened condition of the plant makes it a prime candidate for aphid infestations.
By providing proper care and addressing the underlying issues, you can fortify your plant’s defenses against aphids. Ensure it receives adequate sunlight, supply it with the necessary nutrients, and maintain a consistent watering routine to alleviate stress.
With your attentive care, you can shield your Mandevilla from aphid attacks and help it regain its strength. However, when the plant has organic debris filling the surrounding, you can also see how they will be attracted, as they are trying to find a hiding place, and a location to develop.
– Color Attraction
Aphids are known to be attracted to certain colors, and green is certainly one of them. Mandevillas with their vibrant green foliage could potentially draw aphids due to their color preference.
These little and colorful pests have pear-shaped bodies, long antennae, and two short tubes called cornicles at their rear. Aphids infesting Mandevillas are usually orange, making them easily mistakeable for spider mites. But despite their pleasant color, they do significant damage, causing the leaves to turn yellow and stunt the plant’s growth.
Aphid damage to plants goes beyond this — some aphid species, such as the leaf curl ash aphids, use saliva to curl the leaves while feeding on the plant’s sap. This can result in shriveled stems, dead leaves, and a lack of flowers, and it’s all because the color made them attracted to the plant.
– Environmental Factors
Warm temperatures, like a cozy blanket, create an inviting atmosphere for aphids to flourish. In this balmy environment, aphids reproduce at a rapid pace, building their populations with astonishing speed. The heat provides them with the ideal conditions to thrive and propagate, in addition to the dryness of the environment or the humidity.
High humidity adds another layer to this intricate tale. Like a humid rainforest, it becomes a nurturing haven for aphids. The moist air offers them respite and facilitates their activities, enabling them to extract sap from plants with ease. The combination of warmth and humidity becomes a siren’s call for aphids, drawing them closer to their unsuspecting hosts, and with all ease, you will see them thriving.
To complicate matters further, overcrowded plantings intensify the aphid dilemma. In a densely packed garden, Mandevillas find themselves in close quarters with their leafy companions. This proximity creates an aphid paradise, where they can hop from plant to plant, spreading their influence and multiplying their numbers.
How To Fight the Orange Aphids on Mandevilla?
To fight the orange aphids on mandevilla, you should squish, squirt, and spray them, and wait for predator pests to come along. In addition, use essential oils and neem oil to the rescue, you can also use rubbing alcohol, stay vigilant, and place row covers and prune the weeds.
– Squish, Squirt, and Spray
Carefully hold the affected parts of the plant between your thumb and forefinger, and gently drag your fingers along the stem. This method helps dislodge a significant number of pests without causing harm to the plant.
Especially effective if you don’t have a weak stomach and if the infestation hasn’t gone out of hand, but do note that this is best if you see the little orange pests and tackle them fast before they grow so strong.
Using a hose or a strong spray bottle filled with water, aim at the stem and apply a forceful spray to blast away the remaining aphids. Next up, use insecticidal soap or horticultural oil to spray the aphid colonies. Both options are effective, but remember that soap may have a slightly stronger impact on the foliage.
By following these steps, you’ll be able to tackle the pest problem and protect your mandevilla plant without going overboard as it is still growing. Most adult aphids don’t have wings, but when their colonies get overcrowded or food becomes scarce, some develop wings to travel to other plants. This happens quite often since aphids tend to feed in large groups.
– Wait for Predators
Enhance your garden’s harmony and attract beneficial insects to lend a helping hand. You can do this by either trying to breed some lacewings and ladybugs so that they would take control of them.
You may also go ahead and include a variety of lovely flowers in your garden, such as marigolds, calendula, sunflowers, daisies, alyssum, or dill. These plants have a natural charm that appeals to certain insects, and as they get attracted to your garden, you will see them feeding on the aphid population.
The diverse array of flowers will soon draw ladybug beetles to your garden. They’re known to have a healthy appetite for aphids, making them excellent allies in pest control. For instance, you should consider how the lacewings, with their delicate and intricately patterned wings, are another breed of beneficial bugs. They’ll naturally prey upon aphids, maintaining a balanced ecosystem in your garden.
As your sidekick insect population grows, they’ll continue to regulate aphid numbers, promoting the overall health of your plants. Observing ladybugs and lacewings as they go about their vital tasks adds a touch of wonder to your garden experience, all while ensuring your Mandevillas remain healthy and thriving.
You might be surprised to learn that certain smaller bird species are natural aphid hunters. These feathered friends can help keep aphid populations in check by feasting on both the aphids and their eggs. Creating a welcoming environment through the cultivation of specific flowers and using diatomaceous rock to deter ants can aid in attracting these aphid-hunting allies.
In addition, to encourage these helpful birds to visit your garden, you can take a simple step. Aside from growing small bushy trees, you can sprinkle a bit of Diatomaceous earth around the bases of your plants, if you feel like the population is growing, you can always aim for a combination of choices.
– Use Essential Oils
Harness the natural power of essential oils to address the oleander aphid problem using a simple household remedy.
Clove, peppermint, rosemary, and even thyme essential oils work wonders. These oils are known for their properties that help repel aphids, and this is why you should combine four to five drops of your chosen essential oils in a spray bottle with one cup of water. Give it a good shake to ensure proper mixing.
To maximize effectiveness, spray your plants every two to three days, and not more as you can damage the plant in the long run. Hence, you must pick either the morning or evening hours for spraying, as these are optimal times for plant absorption and reduced sunlight intensity.
Consistency is key, because you will see how over time, the essential oils will work gradually to diminish and control the oleander aphid infestation. Patience and persistence will yield positive results. The power of nature’s remedies will help protect your plants and restore balance to your garden. However, you must also ensure thorough coverage by focusing on the undersides of leaves where aphids tend to congregate.
– Neem Oil to the Rescue
With neem as your ally, you can address aphid issues in a measured and environmentally friendly manner. Neem tree oil offers two effective methods to combat aphids, and these are both useful as long as you are using them in an efficient way.
Neem tree oil offers another organic option, with the ability to create a soil soak or foliar spray to combat aphid populations effectively. Use cold-pressed neem tree oil to create a soil soak.
This technique selectively targets bugs that feed on your plants while keeping bees and other good insects safe. It acts gradually over time, boosting the plant’s immune system and reducing the aphid population without causing harm to other helpful creatures.
Clarified hydrophobic neem oil, used in commercial pesticides, serves as an excellent foliar spray. While it acts upon direct contact with aphids, it doesn’t provide instant results. With patience, this method proves effective in controlling aphids over time.
It’s important to note that you may observe changes in about two weeks after implementing these neem-based solutions. Neem is considered safe and non-toxic, allowing you to use it preventatively every two weeks. In short, its gradual yet reliable effects provide peace of mind for a thriving garden.
– Use Rubbing Alcohol
If you’re seeking a practical and direct method to tackle aphids. To implement this method, take a swab or cotton ball and dip it in alcohol and only target them. Gently and carefully coat the aphids with the alcohol, ensuring thorough coverage. While it may require a bit of time and patience, this method can effectively eliminate aphids on the spot, and this way, the right chemicals will harm their bodies.
Alcohol acts as a potent agent against aphids, disrupting their delicate balance and causing them harm. When alcohol comes into contact with the aphids, it can effectively kill them, offering a direct and immediate solution to the problem.
– Stay Vigilant and Use Row Covers
A mindful approach coupled with protective measures goes a long way in maintaining a healthy garden environment. Alongside reactive measures, there are a few practical ways to minimize aphid populations proactively!
Make it a routine to check your plants every few days for any signs of aphids. By promptly identifying the issue, you can address it before it becomes overwhelming and harder to manage.
Shield your young plants in the vegetable plot during spring with floating row covers. These covers act as a barrier, keeping aphids and other insects away while allowing essential elements like air, light, and moisture to reach your plants. As your seedlings grow taller or when temperatures rise in summer, removing the covers is safe.
– Prune the Weeds
While watching your plants for aphids is important, we need to be wary of other means through which aphids can infiltrate our plants! Weeds stand out as the most prominent of these.
It’s crucial to stay diligent and stay on top of the weeds in your garden. Sow thistle and mustard, tend to be particularly attractive to aphids. By removing these, you can disrupt the aphids’ access points and maintain control over your garden’s well-being.
Remember, a mindful approach to weeding will help keep those aphids at bay and protect your plants from unwanted infestations. Dealing with orange aphids on Mandevilla vines requires a multi-faceted approach. It is crucial to understand the reasons behind their presence, such as their attraction to green foliage and the vulnerability of weakened plants.
