10 Tips to Get Rid of Aphids on Houseplants

A Guide to Understanding Aphids on Houseplants

If you’re a plant lover, then you’re probably familiar with the annoyance of aphids on your houseplants. Aphids are tiny, sap-sucking insects that can cause serious damage to your plants if left untreated.

In this article, we’ll explore the reasons why aphids infest houseplants, the harmful effects they can have, and what you can do to get rid of them.

Transported by Other Plants or Clothing

One of the main ways aphids end up on your houseplants is through transportation. Aphids can hitch a ride on other plants that you bring into your home.

This is why it’s essential to examine new plants before bringing them indoors. You can also inadvertently transport aphids yourself by carrying them on your clothing.

Be sure to change clothes if you’ve been outside gardening before handling your houseplants.

Out-of-Control Infestation

Infestation is another reason why aphids show up on houseplants. Aphids reproduce at a rapid rate, so it’s essential to catch infestations early before they get out of control.

If you’re noticing damage to your plants and seeing aphids, you’ll want to take action to avoid your houseplants from being destroyed.

Using Fertilizers with High Levels of Nitrogen

Did you know that the type of fertilizer you use could be enticing aphids to come to your houseplants? Nitrogen-rich fertilizers promote lush, green foliage that draws aphids in.

Be sure you are using the correct type of fertilizer for your plants, and avoid overfertilizing.

Aphids Eating Vegetable Seedlings

Aphids also have favorites. If you’re growing vegetable seedlings, know that aphids adore these plants.

You’ll want to pay extra attention to your seedlings to avoid infestations.

Moving in Through Open Windows

Aphids become most active during late spring when the weather is warmer. Open windows can also invite aphids into your home.

Make sure you have screens on your windows to keep these pesky insects out.

Eating Mature Plants

Aphids don’t just damage your young plants. Aphids have no preference when it comes to age and can cause issues for your mature plants as well.

Mature plants that become infested with aphids typically experience stunted growth and yellowing of the leaves.

Physical Damage to Plants

Now that we’ve covered why aphids become problematic, let’s discuss the harmful effects they have on your plants. The most apparent way aphids damage plants is by feeding on the sap.

The sap that aphids feed on is integral in keeping your plants healthy. Aphids use their mouthparts to suck sap from leaves and stems, causing deformities and yellowing.

If left untreated, severe damage can occur and result in death to the plant.

Producing Sticky Honeydew Residue

As aphids sip on sap, they also release a sticky substance, known as honeydew, onto the leaves of your houseplants. This honeydew residue attracts ants and creates an optimal environment for the growth of fungi that can damage your plants even more.

Causing Sooty Mold Growth

Sooty mold is a result of the honeydew residue aphids leave behind. This mold adheres itself to the plant’s surface, blocking the plant’s ability to obtain light that helps meet its nutritional needs.

The growth of sooty mold can stunt the growth of your plants and leave them looking sickly.

Favorite Plants of Aphids

Aphids have favorites- it’s not just your vegetable seedlings they are interested in. Plants that aphids ardently enjoy include herbs, like basil and mint, and ornamental plants like roses and chrysanthemums.

It’s essential to keep an eye on these plants for aphids, so they don’t end up causing damage.

Getting Rid of Aphids

Now that you understand why aphids invade your houseplants and the issues they cause let’s discuss getting rid of them.

Natural Methods

One of the simplest ways to eradicate aphids is by using natural methods. This method involves spraying your plants with a combination of water and dish soap.

The solution will break down the waxy coating that protects the aphids and dehydrates them. Another option is to introduce natural predators to your plants’ environment, like ladybugs or lacewings.

While these methods work, they may require multiple applications and take time before they have a visible impact.

Chemical Treatments

If natural methods don’t work or the infestation is severe, you can use insecticidal soaps or oils. These treatments are formulated to kill aphids without damaging your plants.

Before applying, carefully review the instructions to determine the appropriate amount for your plant and follow safety guidelines.


In conclusion, aphids can wreak havoc on your houseplants, but they’re not impossible to get rid of. By understanding why aphids show up, the damage they cause, and effective treatment options, you’ll have the tools to keep your houseplants healthy and thriving.

Remember, prevention is key, so examine your new plants, use suitable fertilizers, and take swift action if you notice any signs of an infestation. With these tips in mind, you can enjoy your vibrant houseplants all year long.

Getting Rid of Aphids on Indoor Plants

Aphids on houseplants can be a frustrating and stressful problem for plant owners. These tiny, sap-sucking insects can reproduce rapidly and quickly overrun a plant if left unchecked.

Fortunately, there are several ways to get rid of aphids, and preventing their infestation in the first place.

Remove Aphids by Hand or with Water

One of the most efficient and cheapest ways to remove aphids is through manual removal, preferably by using your hands. This method is highly particular in small infestations and provides you with an opportunity to closely observe your plant and identify any additional damage.

To do this, you should inspect each leaf for aphids and remove them by hand, making sure to finely pinch them, and you may also get rid of them by gently wiping them away with water. Use a hose, showerhead, or gentle spray to rinse your plants carefully with water under the sink over a bucket filled with soap water.

Using Sprays or Oils to Treat Houseplants

Suppose a manual removal is not practical for you, or the infestation is too great to handle. In that case, you may want to consider using sprays or oils specifically formulated to rid houseplants of aphids.

Many commercial products are available and can be found easily at hardware stores, home centers, and online. Agricultural oils and insecticidal soaps are also useful in treating aphids.

These products are applied to the plant’s foliage, and they act by smothering the aphids and interfering with their respiratory system. When using sprays or oils, please read the instructions carefully to ensure that you do not harm your plant or apply too much product.

Trap Wandering Aphids with Sticky Traps

Sticky traps are an excellent option to get rid of wandering aphids that are not actively feeding on your plants. Sticky traps are tapes that have an adhesive side on one surface, and they attract flying insects by the color of the tape, which is available in bright colors that most aphids are attracted to.

Sticky traps are hung near the plants and can catch wandering aphids, leaving your plants safe.

Preventing Aphids on Houseplants

Preventing aphids on houseplants is a crucial aspect of maintaining a healthy and beautiful indoor garden. There are several strategies to prevent the infestation of these insects.

Check Houseplants Frequently

Frequently checking your houseplants for infestations and damage is important. Inspect your plants regularly for any signs of aphids, such as wrinkled or distorted leaves, stunted growth, or unusual discoloration and damage.

The sooner you detect them, the easier it is to manage the aphids before they spread.

Isolate Infested Plants

If you notice aphids on a houseplant during your inspection, immediately isolate the infested plant. Place the plant in a room away from other plants, so the aphids do not spread to nearby plants.

Thinly coat the plant’s base with petroleum jelly or petroleum oil to trap any crawling aphids and prevent them from reaching other plants.

Use Low Nitrogen Fertilizers

Aphids are attracted to new, tender growth, which higher level in nitrogen fertilizers. Make sure you are utilising low nitrate fertilizers specifically intended for the plant you are growing.

Low nitrogen fertilizers reduce a plant’s susceptibility to aphid attacks.

Place Screens Over Open Windows

Aphids arrive in warmer weather, and open windows may provide an entry point into your home. Be sure to place screens over your open windows to prevent aphids from getting inside.

Change Clothes After Working Outside

Aphids can wander onto your clothing while you are gardening outside, so exchanging your clothes after working outside and washing them would help reduce the chance of aphids being transported inside your home.

Use Aphid Traps in Your Home

Aphid traps are also useful in controlling an infestation. You can make your own traps using yellow index cards smeared with petroleum jelly or a mixture of dish soap and water.

The yellow attracts the aphid, and the sticky substance traps and kills them. Traps should be spaced evenly in the infested area for best results.


Aphids can be persistent and problematic, particularly if left untreated, and it’s critical to detect any infestation as early as possible. Once these pests are detected, they should be quickly managed following the tips provided above.

The most effective method for treatment or prevention will depend on the severity of the infestation and type of plant. By checking frequently, using low N fertilizers, isolating infested plants, placing screens over open windows, spraying your plant with harm-free oil or soap, and using sticky traps, you can prevent the growth and spread of aphids in your home.

In conclusion, knowledge about aphids, their effects on houseplants, and methods to prevent and manage their infestation are essential for plant owners. Regular checks, appropriate fertilization, frequent monitoring, and early detection of aphids are crucial in maintaining the health and visual appeal of indoor plants.

Additionally, taking preventative measures such as using screens on open windows and changing clothing after gardening can prevent the entry of these insects into your home. By following the steps mentioned in this article, you can ensure that your indoor plants bloom uncontrollably and maintain a safe, healthy environment in your home, making your hard work gardening indoors worthwhile.
