Aphids are a common pest on indoor house plants and can cause damage to the plant if left unchecked. They are tiny sucking insects from the insect family Aphididae, measuring less than 1/8 inch in length. It is common to find light green aphids on houseplants (pear aphids), but pink, white, gray, and black are also common.

Fortunately, there are several ways to control aphids on indoor house plants without resorting to chemical controls. One of the best methods is introducing beneficial insects, such as using horticultural oils or soaps to smother the pests or spraying them with a strong jet of water to knock them off the plant. Read on to learn more about it.

What do Aphids do to Plants?

Aphids are a common pest that can cause significant damage to plants. They are highly mobile, quickly traveling from one plant to another and reproducing rapidly. Aphid colonies are often tended by ants in outdoor gardens so they can feed on the honeydew secreted by the insects. Indoors, aphids spread between plants by flying or crawling.

The damage caused by aphids is due to their feeding habits. They suck sap from new growth on plants, clustering at the end of stems and attaching themselves to the soft green parts. This can lead to wilting and yellowing of leaves, stunted growth, and even death of the plant if left unchecked.

Aphids also secrete a sticky substance called honeydew, which can attract other pests such as sooty mold and ants. To prevent damage from aphids, it is important to inspect your plants regularly for signs of infestation and take action if necessary.

Here are 10 Effective Ways to Get Rid of Aphids

1. Use Tape

It may sound silly that such an easy technique can eliminate a huge headache like an aphid. But you can do this in just simple steps. To do this, grab tape, cut it into a small piece, roll it up to the other side, then stick it in your finger. Run the finger through your plants, and the aphids will automatically stick to the tape. This process may take some time, but it’s the most effective.

2. Use Soap

This method works particularly well on tomatoes and other shrubs that are well-established. Adding an insecticidal soap, such as Castile soap, will help if a blast of water does not eliminate the small bundles of insects.

Horticultural oil can be used instead of dish soap for houseplants like succulents. If you want to make a solution using either ingredient, shake them together in a large bottle until they are dissolved.

Using soap and water first effectively eliminates aphids without resorting to harsh chemicals or expensive treatments. Not only does this method save money, but it also helps protect the environment by avoiding the unnecessary use of pesticides.

Furthermore, it’s easy to do and requires minimal effort. All you need is some water and either insecticidal soap or horticultural oil, depending on what type of plant you’re dealing with. With just a few simple steps, you can free your plants from pesky aphids in no time.

3. Pest Control Spray

Using an alcohol spray is an effective way to get rid of aphids on indoor plants. Isopropyl alcohol or rubbing alcohol can create a solution that will kill pests without harming your houseplants. To make the spray, simply mix equal parts water and rubbing alcohol in a small spray bottle.

If you’re worried about the alcohol damaging your plants, add a bit more water but not too much, as this will make the solution ineffective. This method is especially useful for smaller patches of aphids, as you can use a cotton swab dipped in alcohol to brush them away.

Alcohol sprays are easy to make and use, and they are safe for both people and pets. They are also relatively inexpensive compared to other pest control methods, making them an attractive option for those looking to save money while still getting rid of their aphid infestation.

Furthermore, they don’t leave behind any toxic residue as some chemical pesticides do, so you can rest assured that your houseplants will remain healthy and free from harm.

4. Natural Predators

If you want to get rid of aphids without using chemicals, introducing natural predators into your garden is an effective and eco-friendly way. Ladybugs, lacewings, and parasitic wasps are all known to feed on aphids and can be bought from garden centers or online retailers.

Releasing these beneficial insects into your garden will help keep the aphid population down, as they will feed on the pests and lay eggs that will hatch into more predators.

This method is great for anyone looking for a more organic approach to pest control, as it doesn’t involve any harsh chemicals or pesticides. Furthermore, it’s relatively cheap and easy to do, so even novice gardeners can give it a try.

The only downside is that you will need to introduce more beneficial insects as the aphid population grows periodically, but this is a small price to pay for a safe and effective way to get rid of these pesky pests.

5. Neem Oil

Another natural and effective way to get rid of aphids is by using neem oil. Neem oil is a natural insecticide that disrupts the pests’ growth hormones, preventing them from reproducing and eventually killing them off.

It’s also safe to use on houseplants, so you don’t have to worry about it harming your plants or other beneficial insects.

To use neem oil, mix it with water according to the instructions on the label and spray it directly onto the affected plants. Be sure to cover both sides of the leaves and stems and any nearby soil, as this will help ensure that all aphids are killed off.

Neem oil is an effective way to get rid of aphids without using harsh chemicals or expensive pest control methods, so it’s a great option for those looking to go the natural route.

6. Plant Repellents

If you want to prevent aphids from infesting your houseplants in the first place, then using plant repellents is a great way to do so. Natural ingredients, such as garlic, onion, and hot peppers, can be repellents.

Simply blend these ingredients together with some water and spray them directly onto the leaves of your plants. The strong scent of these ingredients will help keep aphids away, as they don’t like the smell and will avoid plants that are treated with it.

Plant repellents are a great way to keep aphids away without using harsh chemicals or expensive pest control methods. Furthermore, they are safe to use on both people and pets, so you don’t have to worry about any adverse effects.

7. Prune-Affected Areas

Another effective way to get rid of aphids is by pruning the affected areas of your houseplants. This may sound counterintuitive, but it’s actually a great way to reduce the number of aphids on your plants. Simply cut off any leaves or stems heavily infested with aphids and dispose of them in the trash. This will help reduce the number of aphids on your plants and make it easier to eliminate the remaining ones.

Overall, there are several ways to get rid of aphids on houseplants without using harsh chemicals or expensive pest control methods. Introducing natural predators, using neem oil, applying plant repellents, and pruning affected areas are all effective methods for getting rid of these pesky pests.

8. Baking Soda and Canola Oil

Home remedies are an excellent way to get rid of aphids on houseplants without resorting to harsh chemicals. One such remedy involves using baking soda and canola oil. The oil coats the insects and breaks down their exoskeletons, making them more vulnerable to toxins.

Because baking soda is abrasive, it also removes the bug’s outer shell, making it easier to remove from plants. Spray the plant with this mixture and combine the ingredients in a large spray bottle.

It is particularly effective on indoor plants that are not exposed to other insects. It is important to note that this remedy should only be used on indoor shrubs or during the dormant season for pests outdoors, as it could harm helpful bugs in the garden if applied too liberally.

With a little effort, you can easily keep your houseplants free from aphids with this simple home remedy.

9. Honeydew

One thing that makes aphids unique is their production of honeydew, a sweet, sticky substance that attracts ants. Ants are drawn to the honeydew and often protect the aphids as if they were livestock to harvest it. Aphids may also increase in numbers if ants are trying to protect their food source due to an increase in aphids.

Keeping plants out of reach of other insects is the best way to prevent this. Pesticide treatments applied to aphids can also work on ants, but preventing them from getting close enough to the aphids in the first place is ideal.

Keeping plants away from windows and doors or using screens can help keep these pests away from your home and garden. Additionally, keeping your garden clean by removing dead leaves and debris can help reduce the number of pests around your home.

10. Spice Up Things

Cayenne pepper is an excellent way to kick up the heat and spice to eliminate pesky aphids on houseplants. After removing all the bugs or solving small insect problems, this natural remedy is a good preventative measure. Cayenne naturally deters aphids and other pests from the plant without introducing harsh chemicals, making it an ideal addition to your bug-fighting arsenal if you don’t have any cayenne pepper but have hot and spicy chile pepper, that also works.

To use cayenne pepper as a pest deterrent, add it to water in a small bowl or spray bottle and soak the plant leaves along with the base. This will help keep out your indoor garden intruders for good.

It’s important to note that this method should be used sparingly, as too much cayenne can damage plants if not used correctly. With proper application, however, you can easily kick up the heat and keep your houseplants safe from unwanted pests.

What are the Things That Attract Aphids to Your Plants?

They are attracted to the sweet juices of plants, which makes them particularly fond of houseplants. Succulents like aloe are especially appealing to aphids due to their large, thick leaves full of moisture and nutrients. These plants provide plenty of meals for hungry creatures, making it difficult to keep them out of your garden or home forever.

Fortunately, there are some steps you can take to reduce the number of aphids in your houseplants. It is possible to counter this issue by planting flowers like marigolds that repel these insects. Additionally, keeping your plants well-watered and pruned regularly can help prevent an infestation from occurring in the first place.

Reasons to Get Rid of Them

Aphids are small, soft-bodied insects that can cause serious damage to houseplants. These pests suck sap from the leaves and stems of plants, causing them to become distorted and discolored. In addition, aphids can introduce diseases such as mildew and mold into the plant. As a result, getting rid of aphids on houseplants as soon as possible is important to protect your plants from further damage.
