Aphids on hibiscus are little insects that can be very harsh on your plants as they are unsightly and quite alarming as they can wreak havoc and easily spread in the garden. If you see any on your plants, it’s best to get rid of them as soon as you can.

These small insects love to feed on the sap of our favorite hibiscus specimen plants, damaging them and making them look sickly.

We’re with you if you can’t wait to get them off your plants, so here are several ways to remove aphids from your hibiscus, so let’s look at the ways we can get rid of and kill aphids that lurk in our hibiscus plants.

How To Get Rid of Aphids on Hibiscus Plant

To get rid of aphids on hibiscus plants, you can start by spraying water on the plant, or using some insecticidal soap on them. You may also tackle them using neem oil, or introducing them to beneficial insects, prune the affected parts and provide the right care.

Aphids are tiny, soft-bodied insects that are usually found on the undersides of leaves or at the tips of new growth. They are often green, black, red, yellow, brown, or gray and can be identified by their pear-shaped bodies and long antennae.

If you notice sticky residue on the leaves or a general decline in the health of your hibiscus plant, it may be a sign of an aphid infestation. Additionally, your plant will experience yellowing, premature leaf deaths, and black sooty fungus molds, so knowing the right methods will help you in the long run.

– Spraying the Plant with Water

Spraying the plant with water is a simple and effective way of getting rid of aphids. The water pressure can knock the aphids off the plant and make it harder for them to climb back up. First, you’ll need to find a garden hose with a strong spray nozzle or a spray bottle with a mist or jet setting. In this case, make sure you have enough water pressure to knock the aphids off the plant.

Turn on the water and adjust the nozzle to create a strong stream of water. If you’re using a bottle with a sprayer, make sure to pump it up to build pressure. Aim the water at the hibiscus plant, targeting the areas where the aphids are congregating. Make sure to spray both the top and bottom of the leaves, as aphids often hide on the undersides of leaves.

Continue spraying until you’ve dislodged as many aphids as possible. Be careful not to damage the plant by spraying too hard or for too long in one spot. After spraying, check the plant for any remaining aphids. If you see any, repeat the process until they’re all gone.

– Use Insecticidal Soap

Insecticidal soap is a type of soap that is specifically formulated to kill insects, including aphids, without harming plants. It works by disrupting the outer protective coating of the insect, which causes it to dry out and die.

After buying the insecticidal soap, follow the instructions on the label for mixing the solution. If you are making a homemade soap solution, simply mix one tablespoon of dish soap with a quart of water. It’s important to use a mild dishwashing soap that does not contain bleach or degreaser to avoid damaging the plants and harming them.

Next, you’ll need to apply the solution by pouring the soap solution into a spray bottle and spraying the hibiscus thoroughly. In this case, you should be very gentle and try to cover the leaves, stems, and any of the hibiscus flowers that may be affected.

Finally, rinse the plant, so after applying the soap solution, rinse the hibiscus with water to remove any residue and prevent any damage to the plant. You may need to apply and rinse the solution a few times over a week or two to get rid of the aphids completely.

While chemical pesticides can be effective in controlling aphids, they can also harm beneficial bugs, insects, and other wildlife. In addition, repeated use of pesticides can lead to pesticide resistance and harm the environment. Try non-toxic methods first and reserve chemical pesticides as a last resort.

– Use Neem Oil Solutions

This oil is a natural oil derived from the grains of the neem tree that has insecticidal properties and can be used to control aphids on hibiscus plants. To use this oil, dilute it first. Oil made from neem is very concentrated and should be diluted with water before use. Mix one tablespoon of the oil with one quart of water in a bottle with a sprayer.

Shake the oil and water mixture well, then spray it onto the affected parts of the hibiscus plant, making sure to cover the leaves and stems thoroughly. Repeat this process every week or two until the aphid infestation is under control, and this way it will ensure you the right outcome.

You must remember that the oil solution can wash off easily, so it’s important to reapply it after heavy rains or watering to ensure it remains effective. Another thing to keep in mind is to avoid using it in extreme temperatures as it can damage parts of the plants. It’s best to apply neem oil when temperatures are between 50 and 90 degrees Fahrenheit and avoid applying it in direct sunlight.

– Introduce Beneficial Insects

Ladybugs and lacewings are natural aphid killer species and can effectively control their population. Ladybugs, also known as lady beetles, are small, colorful insects that feed on aphids and soft-bodied insects like mealybugs and scale insects. Lacewings are delicate, green insects that have a similar diet to ladybugs.

You can purchase these beneficial bugs and insects from a garden center and you can release them onto the plant. They will start feeding on the aphids and lay their eggs on the plant, which will hatch into larvae that also feed on aphids. This will help to control the aphid population and prevent them from resulting in further damage to the hibiscus.

It’s important to release the beneficial insects at the right time when there are enough aphids for them to feed on. Also, make sure to follow the instructions carefully when releasing them, as they can be sensitive to environmental conditions like temperature and humidity. You may need to release multiple batches of beneficial bugs and insects over time to ensure the aphids are kept under control.

In addition to ladybugs and lacewings, other beneficial bugs and insects can help control aphids, such as parasitic wasps and hover flies. However, it’s very strict that you note that not all insects are beneficial, and some may even harm the plant.

– Prune the Affected Parts

You’ll need a pair of sharp pruning shears or scissors to prune the affected parts. First, inspect the plant to determine which parts are infested with aphids. Look for leaves and stems with clusters of insects and any parts of the plant that look wilted or damaged, as they would have damaged them.

Once you’ve identified the affected parts, use the pruning shears or scissors to cut them off. Make sure to cut the parts as close to the main stem as possible, without damaging the stem itself. You can dispose of the pruned parts by putting them in a plastic bag and throwing them away in the trash.

Remember that you cannot add them to any compost bin, as the aphids may still be alive and can infest your other plants. After pruning, monitor the plant regularly for any new aphid infestations. If you notice any new clusters of bugs on hibiscus buds, you can use one of the other methods mentioned earlier to control them.

– Provide the Right Amount of Water and Fertilizers

You can do a few things to prevent aphids from infesting your hibiscus plants, such as regularly fertilizing the plant to promote healthy growth. Moreover, keeping the plant well-watered and providing adequate air circulation are simply ways to protect hibiscus from aphids by giving it the right requirements from the start.
