How do you get rid of Aphids on Cherry Tree?
Getting rid of Aphids on Cherry Tree wasn’t as easy as I thought. Natural remedies only worked temporarily, commercial products didn’t live up to expectations, and there isn’t enough information on the internet.
That’s why I created a list of 16 PROVEN Ways to Get Rid of Aphids on Cherry Tree.
This ultimate guide is broken down by how to get rid of aphids on cherry tree and how to prevent aphids with natural remedies that work, commercial products that live up to expectations, and secrets that only experts know!
What Does Aphid Damage Look Like?
Aphid Damage can be quickly and effectively-identified. You should look for the following:
- Misshaped, curled, or yellow cherry tree leaves
- Sticky substance on the cherry tree stem
- Cherry Tree that are growing deformed
- Galls on the roots or leaves
- Small bugs on the opposite part of the leaf
- Large amounts of small bugs on the stem of the plant.
- Small bugs on the root of the plant
10 PROVEN Tips to Get Rid of Aphids on Cherry Tree
#1.Manually Remove Aphids
If there are less than a dozen aphids…
- Use a dry paper towel, pick the aphids off the individual cherry tree leaves, and gently crush them.
- Dispose of the dead aphids in a garbage bag. Leaving potentially alive aphids behind will just cause a re-infestation.
- After removing the aphids you should inspect your leaf or cherry tree to ensure there are no more aphids.
- Use a wet paper towel to rub any sap or residue from your leaf or cherry tree to prevent additional aphids or even ants from attacking your plant.
- Use a wet paper towel to gently brush the aphids off the cherry tree leaves and into a garbage can.
- Because some aphids have wings and others can crawl at a relatively fast speed you should never brush them into the grass. This can cause re-infestation or infestation of other cherry tree.
- After removing the aphids, you should again inspect your leaves and cherry tree to ensure there are no more aphids
- Use another wet paper towel to rub any sap or residue from your leaf or cherry tree to prevent additional aphids or harmful insects like ants from attacking your plant.
#2.Spray the Infected Cherry Tree Leaves with a HoseIf Aphids are on your entire leaves…
- Spray the underside of your cherry tree leaves in the morning with the high power setting on your hose until the aphids are removed. Low power settings or a watering won’t properly remove aphids.
- Then let your leaves completely dry.
- Spray the underside of your leaves and your plant in the evening again until the aphids are removed.
- To be safe, it is recommended to repeat the steps every day until aphids are completely gone.
- It is also recommended to follow the same steps with healthy cherry tree immediately surrounding your attacked plant to help prevent the spread of aphids.
#3.Use Insecticidal Soap
If there are large amounts of aphids on your cherry tree…
- Use an traditional choice for controlling Aphids, such as Insecticidal Soap.
- Insecticidal Soap is a low-toxicity pesticide made of potassium and fatty acids that have been used by gardeners and farmers for centuries. It can kill large amounts of soft-shell insects like aphids without harming your plants, animals, or humans.
- You can also make your own Insecticidal Soap by combining one cup of oil (peanut, vegetable, corn, etc.) with one tablespoon of dish soap. Do not use bleach.
#4.Use Commerical PesticidesIf Aphids just won’t die then…
- Spray your cherry tree with a systemic pesticide that contains the chemical, Imidacloprid early in the morning. This is a commercial chemical that is non-toxic to humans and beneficial pollinators, but deadly to harmful insects like aphids.
- Repeat applying your pesticide until aphids are dead. It should be noted that it can take up to two weeks to fully kill an infestation of aphids and prevent them from spreading.

#5.Apply an Organic PesticideIf you Want to Get Rid of Aphids Organically…
- Then create your own organic pesticide. You can create it by doing either of the following:
- Mix 3 teaspoons of dish soap with 1 quart of water. You can either spray or gently apply this solution onto your cherry tree leaves
- Mix 1 teaspoon of dish soap, 1 teaspoon of cayenne pepper, and 1 quart of water.
Like a commercial pesticide, you should apply this solution to your cherry tree in the morning until the aphid infestation is gone. Again, it may take two weeks to kill your infestation and it is not as effective as chemical pesticides.
It should be noted that while organic pesticides are almost guaranteed safe to you, children, and animals, it is typically not as effective as commercial products.Do Not Use…
- Coffee Grounds, Banana peels, or any other home remedy that you may read about.
While you may read about these remedies in other articles there is little scientific evidence that they are effective and can even attract other insects or garden pests.
#6.Try Essential Oils
If Organic Pesticide doesn’t work then…
- Use essential oils to get rid of aphids.
- Use 4 to 5 drops of peppermint, clove, rosemary, and thyme and mix it with 1 cup of water. Spray onto the cherry tree with aphids in the morning. You can also apply in the evening too.
- Repeat until the aphids are gone.
Essential oils are not only a great way to get rid of aphids, but also is an effective way to get rid of mosquitoes and other insect pests.

It should be noted that Essential Oils are a great way to Prevent Aphids and should be applied as soon as you grow new cherry tree.
#7.Dust Your Cherry Tree LeavesIf You Don’t Want to Spray Aphids then…
- Apply a light dusting of diatomaceous earth. While not toxic to humans or animals, it can immediately kill aphids with it’s razor sharp particles.
This type of dusting should be used as a last result. It is more expensive than other remedies and can potentially kill beneficial insects and bees that visit your cherry tree.
Dusting is also a great way to prevent aphids. Simply, apply light dusting on your leaves in early summer to prevent harmful insects like aphids from attacking your cherry tree.
#8.Cut Back the Cherry Tree
If Aphids have spread to the entire cherry tree…
- Remove entire leaves or branches of the cherry tree if manually removing aphids, spraying your playing, or applying insecticides don’t work.
- It recommended to first remove leaves. Wait a day. If aphids are still on your cherry tree then remove a few branches. Never remove more than one-third of the branches on your plant or it will die.
- Dispose of your infected leaves or branches in the garbage. Do not leave them near other plants where the aphids can spread and do not compost them.
#9.Attract Beneficial Insects
If you don’t want to use spray…
- Then grow cherry tree that will attract ladybugs, hummingbirds, and green lacewings.
- These bugs and birds are the best at most effectively and quickly eating and getting rid of aphids.
Ladybugs and Lacewings are the best type of insects to eat and destroy aphid eggs and larvae.
Birds like chickadees are the best animal to attract to eat and destroy large numbers of adult aphids.
Not only are beneficial insects great to help get rid of aphids, but they are essential in preventing aphids infestations.
Ladybugs, lacewings, and chickadees are also great creatures to attract to keep ant colonies away from your plants. Ants are known to be attracted to aphids and also protect them.
- Some of the best plants to grow that will attract these aphid predators include:
- Mint, Cherry Tree, Dill, Yarrow, Dandelions, Coneflowers, and Daisies.

#10.Stop Growing Certain Other Plants
If none of the above steps work then…
- Stop Growing the Plants around Cherry Tree that are attracting Aphids. This will help get rid of aphids and also prevent them.
These plants tend to have large leaves with shade where aphids can feast. Some of these plants are:
- Green Beans
- Sweet Potato
- Brussel Sprouts
If you really want to keep growing these plants then it is recommended you move them to a different part of your yard to reduce the spread of aphids to cherry tree.
11.Apply Neem Oil
The Most Effective Way to Prevent Aphids is to…
Apply Neem Oil
- While you can make your own organic neem oil it is recommended to mix commercialal Neem Oil with water in a garden sprayer and apply it onto all your fruit and vegetable trees in mid to late winter immediately before the last frost.
*Commercial neem oil is as safe as diy neem oil*
Find your last frost date HERE.
You will need to spray your cherry tree several times before the spring to destroy aphid eggs and repel mature aphids. Neem Oil will not kill beneficial insects with hard shells and bees.
12.Pick the Right Neighboring (Companion) Plants
If you want to increase the likelihood of preventing aphids from attacking your cherry tree then you should plant the following (around plants that get attacked) that have strong scents that insects hate:
These are also great plants to deter other garden pests like deer, squirrels, and chipmunks.

You can also grow plants that attract aphids to a different part of your garden or yard to prevent infestation to your good plants. These include:
If you urban garden or have a very small space for these plants then it is recommended to use gardening pots for these plants to help save space.
Fertilizing promotes new growth, faster.
Aphids are attracted to new cherry tree growth almost 100% of the time.
Instead of fertilizing your cherry tree all at once, you should apply smaller amounts of fertilizer throughout the year. You can also apply fertilizer once with a slow-release solution.

14.Keep Cherry Tree Watered
Keep your cherry tree well-watered throughout the year.
This is especially important during hot summer days or droughts.
When cherry tree aren’t watered they become weakened, which decreases their chances of producing chemicals that can help them fend off harmful pests like Aphids.
If you notice that aphids continually come back to your plants every year then it is recommended to water at least one more day a week.
15.Use Silver Reflective Mulch
Based on scientific studies at farms and gardens across the world, it has been proven that silver reflective mulch, also known as mylar, is effective at repelling aphids.
All you need to do is lay the mulch throughout your garden, grow your cherry tree in the mulch hole, and expect no aphids or dangerous insects.
Not only that, but mulch is a great way to prevent weeds and help your cherry tree retain valuable water and nutrients they need to grow vegetables.
16.Destroy Ant Colonies
When you find aphids around your cherry tree you’ll also usually find ant colonies.
Ants can be found around aphids because they eat the waste aphids produce called “honeydew”.
Ants then protect aphids against beneficial insects like ladybugs and this can cause infestations to get larger, quicker.
Destroy ant colonies anywhere in your yard and around your cherry tree with one of the pesticides listed above.
And don’t forget to wipe off the cherry tree that had aphids on it. Even after ants and aphids are dead, leftover honeydew can attract other ants.
As a reminder, there are 16 Proven & Effective Ways to Get Rid of Aphids on Cherry Tree. They are:
- Manually Remove Aphids
- Spray Leaves or the Cherry Tree that have Aphids
- Use Insecticidal Soap
- Use Commercial Pesticide
- Apply an Organic Pesticide
- Use Essential Oils
- Dust Your Cherry Tree & its leaves
- Cut Back Your Cherry Tree
- Attract Beneficial Insects
- Stop Growing Certain Plants
- Apply (commercial) Neem Oil
- Grow Companion Plants
- Don’t Overfertilize
- Don’t Forget to Water
- Use Silver Reflective Mulch
- Destroy Ant Colonies
How to Kill Aphids in Cherry Trees Before Spring | Home Guides
By SF Gate Contributor Updated July 26, 2021
Aphids are trouble for a wide range of plants, and the cherry is not exempt from this pest. The most common aphid in cherries is the black cherry aphid (Myzus cerasi), a 1/8-inch-long, shiny black aphid that overwinters as eggs on the bark of smaller cherry branches, emerging in the spring about the time buds are opening. After three to four weeks, these young females begin giving live birth to more wingless females without the need for fertilization. Populations of cherry tree aphids, or black bugs on cherry trees, can quickly get out of hand – killing them before they hatch is the best form of control.
1. Water Your Tree
Provide your tree with supplemental water at least a week prior to beginning to treat it for aphids. Water it until the soil is moist, but not so much that the tree is standing in water. A well-hydrated tree is less likely to be injured by horticultural oil treatments.
2. Treat Your Tree
Spray horticultural oil on your cherry tree, making sure to coat the bark and branches thoroughly. Apply this treatment in the evening if bees are active near your cherry tree, since it can be toxic to these pollinators. Allow the spray to dry at least four hours before treating the tree further.
3. Monitor the Population
Place yellow sticky cards on the branches and trunks of cherry trees in late winter, as buds begin to swell, to help monitor aphid populations. You can find these from integrated pest management dealers. Check the sticky cards regularly – if you see tiny black aphids (immature aphids are much smaller than adults), prepare to spray again before populations climb.
4. Use Insecticidal Soap
Coat your cherry with insecticidal soap as soon as black cherry tree aphids are active, or wait until after the petals fall from the tree to apply imidacloprid to the soil around your tree. Repeat applications of insecticidal soap weekly until you don't see any more aphids on sticky cards if you choose this option.
5. Control Overwintering Aphids
The Old Farmer's Almanac suggests that if you spray dormant horticultural oil, you will kill overwintering aphid eggs. That should give you a head start on aphid control in spring. Most aphids cause damage when temperatures are between 65 and 80 degrees.
6. Use Biological Controls
One of the best ways to get rid of cherry tree aphids is to introduce biological controls, according to Washington State University Tree Fruit. Lady beetles, soldier beetles, predacious midges, lacewing larvae and syrphid flies are all good biological controls of aphid populations.
Things You Will Need
Insecticidal soap (optional)
Biological controls (lady beetles, lacewing larvae, etc.)
Aphids are often well controlled by beneficial insects once abnormally large populations are reduced in size. Refrain from applying broad-spectrum insecticides to allow these insects to help you with pest control. Cherry trees (Prunus spp.) are hardy in U.S. Department of Agriculture plant hardiness zones 2 through 8.
Watch for ants in your trees – if they discover an aphid population, they may protect these sap-sucking insects from natural predators by feeding on honeydew that the aphids secrete.

Aphids on cherries
It is very easy to notice the appearance of this pest on trees - the leaves (especially at the ends of branches) begin to curl and dry up. If measures are not taken to combat aphids, then young trees may die, and adults may lose a significant part of the crop.
If you unfold the cherry leaf, you can see black and yellow small insects - this is the aphid. Most likely, along with it, you will also see a cluster of ants on the tree, as they feed on aphid secretions. If aphids are found, take immediate action.

How to get rid of aphids on cherries
The fight against aphids is either folk remedies or special preparations. What is better?
Folk remedies get rid of aphids for a short time, basically they simply reduce the number of the pest. Therefore, you will have to process cherries several times per season, and this is quite dreary. But it is safe for health. This is on the one hand.
On the other hand, it is much easier to get rid of aphids with drugs, since usually one treatment is enough. And if you follow the instructions for use, without violating the waiting time, it seems like it’s not so dangerous. But if aphids appeared when the tree had already blossomed or fruits had formed, then chemistry can no longer be used, since firstly you can poison the bees; secondly, yourself. At the chem. aphid preparations usually have a long waiting period, that is, by the time the cherry ripens, the active substances of the insecticide may not yet decompose into safe substances.

How to treat cherries from aphids
Folk remedies are all kinds of herbal infusions that repel aphids, or environmentally friendly products that help to destroy aphids. Let's consider some of them.
- Soap solution and ash . You can destroy the aphids on the cherry (or at least reduce the number of the pest and protect it from new settlers for a while) with a soapy solution with the addition of ash. Dissolve a piece of laundry soap in a bucket of water and add a glass of wood ash to the solution. Grate soap for better dissolution. Wet the whole tree liberally with this solution, and the leaves should be sprayed on both sides. If there is no ash, then you can treat the cherry only with soap.
- Garlic solution . Often, garlic infusion is used to kill aphids, prepared either from the arrows of garlic, or directly from the heads. Pass the garlic through the prss or grate it and cover with plain water. Usually it is 200 g of garlic per 1 liter of water. Insist for 3-5 days. Then strain and add 40-50 ml of this infusion when spraying on a bucket of water. The aphids cannot stand the garlic "spirit", so they quickly retreat to another place. Hose water . You can also knock aphids off cherries with water under good pressure.
- Milk and iodine . Spraying cherries from aphids can be done with milk and iodine. Take a vial of iodine, 100 g of milk and 1 liter of water. Mix everything, then pour into a sprayer and spray the tree. Along the way, spray berry bushes, they will also come in handy, since aphids especially like to settle on red and black currants.
- Coca Cola . Surprising to many, but the fact is that Coca Cola helps get rid of aphids. And the thing is that this drink contains phosphoric acid, which kills the pest. Dilute cola 1:1 with water and spray aphid-infested trees and plants.
- Baking soda . The easiest way to control aphids is to spray cherries with baking soda. 80-100 g of baking soda is dissolved in 10 liters of water and trees are treated with this solution. The method is good because it is possible to spray trees and plants at any stage of development.
- Dry mustard . Dissolve 100 g of mustard powder in 10 liters of water. Neither aphids nor ants can stand the smell of mustard, so with one remedy you will repel both. For better sticking to the leaves, add a little liquid soap to the solution.

Preparations for fighting aphids on cherries
- Fitoverm . I would advise you to first try to get rid of aphids with this biological preparation. Usually treatment with Fitoverm gives good results. To prepare a working solution, dilute 1 ampoule (5 ml) per 600 ml of water. Usually, aphid spraying is carried out as soon as the pest is noticed, usually before flowering. The second time you should spray the cherry after flowering, but no later than 5 days before harvesting. It is optimal when up to 20 days pass between treatments. Do not process cherries during flowering.
- Aktara . This drug when the number of aphids on a tree is very large, in this case folk remedies will not help you. Spraying with Actara is carried out only before flowering, as it has a long waiting period. You can eat fruits only 60 days after the treatment.
- Confidor . In the fight against aphids, the drug Konfidor has proven itself well. It kills aphids, but it also stimulates leaf growth. Confidor is also suitable for the southern regions, since even heat does not weaken its protective effect. You need to process cherries with these drugs only 1 time per season. 2 g Confidor per 10 liters of water if there are few aphids, if the pest numbers are high, dilute a double dose. Use the solution on the same day, as it is not subject to storage. For better adhesion of the solution to the leaves, add liquid soap to it.
- Insecticides Spark , Decis , Intavir , Karate , etc. will also help against aphids on cherries. Use these drugs strictly according to the instructions, be sure to observe the waiting period.

Every gardener had to deal with the fact that the trees in the garden are occupied by pests. For example, aphids on cherries are quite common. Consider the signs of its occurrence, control and prevention measures.
General pest information
Black aphids, which most often appear on cherries, are small, dark-colored insects averaging 2 mm in length. They feed, like other species of this pest, with juice, which is obtained from the tissues of young shoots, leaves and buds. Aphids especially love the tops of the shoots with the most tender leaves. Thus, insects weaken the plants, the leaves on them curl, do not develop, and if the pests managed to occupy the shoots before flowering, then the flower buds are also affected.
Aphids begin active activity on cherries in early spring, with the onset of the first warm weather. As soon as the buds begin to bloom, the pests reproduce quickly, they are able to give several generations in a season. If urgent measures are not taken, the crop can be seriously affected by aphids.
How to understand that an aphid has settled on a cherry
Finding pests on the leaves of trees is not difficult, you just have to look at them carefully. Aphids are more often located on the youngest leaves, mainly on their lower side, and if single specimens are not so clearly visible, then it is difficult to miss an already sufficiently multiplied colony.
A characteristic sign of plant damage by aphids is a sticky liquid that covers the leaves, which makes them shiny. The leaves are deformed and curled. Near pests, you can see ants that specifically grow aphids because of their sugary secretions.
The danger and harm of aphids is not only in the weakening of plants, but also in the fact that it carries viral infections, and the sweet liquid serves as a breeding ground for soot fungus.
How to deal with aphids in the garden
Naturally, it is impossible to leave everything as it is, so as not to lose a significant part of the future harvest. The fight against aphids should be started immediately, as soon as it is detected. You can save a tree with the help of folk remedies, agricultural chemistry, or attracting natural enemies of the pest. Each of these methods has its own advantages and disadvantages. Which one would be more appropriate to apply depends on the desire and capabilities of the gardener.
If there are still few aphids, it is better to try to get rid of them by using water, that is, simply wash them off with a stream of water. But this method is only suitable if the pests have not yet had time to multiply strongly.
In addition, you can fight with folk remedies. They are not as aggressive as commercially produced insecticides, and are not harmful to plants, do not poison them. But it should be borne in mind that folk remedies are not so effective - cherries will have to be processed not once per season, but several.
Soap and Ash
Cherry aphid killer recipes:
- Soap solution. It will be necessary to dissolve shavings from ½ a piece of laundry soap (150 ml of liquid or 150 g of tar) in 10 liters of hot water. Spray the cherries with this solution.
- Ash infusion. This tool is doubly useful: it not only destroys aphids, but also feeds cherries with mineral elements. Cooking it is simple: pour 0.3-0.5 kg of ash into 5 liters of boiling water and leave to infuse in a sealed container for a day. Then add another 5 liters of water, add 50 g of any soap and use the infusion for spraying.
According to gardeners, these aphids are time-tested and show good results after the first application.
No less effective in the fight against aphids and plants with insecticidal properties, which can be found in any household.
Top 10 herbal infusions against aphids:
- Bow. Take 30 g of husk, pour 1 liter of boiling water, leave for 6 hours. Add a little laundry soap to the liquid for the product to stick to the leaves.
- Garlic. 200 g of crushed cloves insist 5 days in 1 liter of water in a sealed container. Before use, dilute 25 g of infusion in a bucket of water.
- Tobacco. 200 g of dry leaves insist in 5 liters of water for 2 days. Add another 5 liters of water.
- Chamomile. 100 g of inflorescences and herbs insist 12 hours in 1 liter of water. Working solution: dilute the infusion with water 1 to 3, add 5 g of soap for every 1 liter of the resulting liquid.
- Marigolds. Fill the bucket up to half with crushed plants (together with flowers), add water to the top, leave for 2 days, add 50 g of soap to the bucket before spraying.
- Hot pepper. 1 kg of fresh pepper in pods or 0.3 kg of dry insist in 10 liters throughout the day. Dilute with water 1 to 10.
- Pine. Infuse 1 kg of needles in 4 liters of water for a week. The concentration of the working solution is 1:1.
- Citrus. Pour 100 g of dry peels into 1 liter of hot water, leave for 3 days.
- Potatoes or tomatoes. Infuse 1 kg of fresh or 0.5 kg of dry leaves in a bucket of water for 6 hours.
- Celandine. 400 g of fresh grass or 100 g of dry, pour 1 liter of boiling water, leave for 1-1. 5 days.
All infusions must be filtered before use so that the liquid is clear, without impurities and does not clog the sprayer, and then spray the plants.
Spray carefully to get the solution on both surfaces of leaves and shoots. Processing of cherries can be carried out during budding, after flowering, during the period before the berries ripen, but no later than 2 weeks before they are harvested.
Those who want to deal with black aphids "immediately and permanently", of course, will have to choose synthetic insecticides. They act quickly and as efficiently as possible, but you need to remember that you can use them only at the beginning of the season, but not when the berries are already ripe.
Insecticides may be used in the home garden:
- Fufanon and others
It is recommended to spray cherries for prevention even before bud break - this will destroy the wintering aphids. And during the season it is better to alternate drugs so that the pest cannot get used to one of them.
The last treatment before picking berries must be carried out no later than the time indicated in the instructions for the drug as a waiting period!
Control measures for black aphids include planting crops and flowers with a strong smell near fruit trees:
Their pungent or spicy smell should repel pests.
You can fight aphids by attracting birds that actively eat pests to the garden:
Insects that are enemies of aphids can also be attracted:
- predatory bugs,
- ground beetles,
Plant daisies for hoverflies, amaranth for ground beetles, ferns for lacewings, and earwigs in wood shavings. Naturally, if such a control option is chosen, it is impossible to use pesticides so as not to poison the birds and beneficial insects.
So that the cherry aphid does not breed in the garden and it is not necessary to figure out how to deal with it, some preventive measures must be taken. For example, a pest likes to hide in weeds, it can live on viburnum, linden and bird cherry, so you need to regularly weed out weeds, shoots, remove their remains in the fall, then whiten tree trunks to prevent aphids harmful insects from getting wintering. Anthills should be destroyed, preventing ants from taking care of aphids and spreading them to new plants.
The pest is more likely to settle on plants overfed with fertilizers, so it is important to adhere to the norms during top dressing, not to add more mineral elements to the soil than necessary.
