How To Get Rid Of Aphids

Whether you are an experienced gardener or you’re just getting started, you likely already know about aphids. These tiny insects reproduce rapidly and feed on all kinds of plantlife. They can wreak havoc to your garden and often require consistent control and monitoring to keep them from destroying garden plants altogether.

Are you wondering how to get rid of aphids? Then this is the article for you. Join us as we learn more about these annoying garden pests and discover the different methods you can use to get rid of them and prevent them from returning.

What Are Aphids?

Aphids are rapid reproducers who can produce many different generations in one season.  

Aphids are small insects who typically don’t grow any larger than 1/4th of an inch in length. They range in color and can be yellow, green, brown, grey, black, pink and white.

If you’re wondering how to get rid of aphids, you should know what they look like, even if they’re hard to see. Up close, aphids look almost like small grasshoppers.

Aphids have long antennae, curved back legs, and two tubes on their back ends which are called cronicles. Most adult aphids do not have wings, though they are known to develop wings if their food source becomes overcrowded and they need to leave to begin a new colony elsewhere.

Otherwise, aphids generally stick to the same food source and will not travel too far from it. If they are knocked off or fall off their food source, however, they tend to have a terrible sense of direction and often need to find food elsewhere.

There are numerous species of aphids found across North America, and they are a common garden pest known to feed on a variety of plant life. While one or two aphids won’t cause too much damage, in large colonies aphids can destroy your garden and stunt or prevent newly growing vegetation and crops.

Most active in spring, aphids prefer new plant growth and are especially fond of buds. They target a number of plants and parts of plants like flowers, fruits, stems and roots, but some species of aphids prefer specific vegetation like potatoes, cabbage, melons, apples, beans, peaches, and more.

Aphids reproduce quite rapidly, with female aphids laying between 50 to 100 eggs in her lifetime. That’s around five offspring a day! More interestingly, some aphids are able to reproduce by parthenogenesis, meaning they don’t need their eggs to be fertilized and can bypass the egg stage altogether, giving birth to live female nymphs.

When aphids do lay eggs, they are generally laid on leaves. The eggs can be dormant over winter and then hatch in spring, where it takes nymphs about a week to reach maturity. Once mature, they reproduce all over again. Since these insects are such prolific breeders and mature at such a fast pace, there are often many generations of aphids produced in a single season.

The below video further discusses the interesting life cycle and reproduction stage of aphids. 

Though aphids do reproduce quickly, they have a short lifespan, with some adult species living only as long as a week while others can live up to 40 days.

Still, even in that short span of time, they can cause serious damage. So, why do you have aphids and how can you get rid of them?

Let’s find out.

What Has Attracted Aphids To Your Garden?

Over-watering your garden can attract more aphids.

Aphids target vegetation because they feed on plant juices and sap. No matter where you live in North America, if you have a garden then you likely have aphids. That said, there are a few things you may be doing that are attracting more aphids to your garden than usual.

If you’re planting a lot of new plants or have new growth popping up your garden, you’re providing a smorgasbord for aphids of all their favorite meals. During this time, it’s best to monitor your new plants and use the methods we’ll discuss below to control and get rid of aphids.

But why else could you have so many aphids in your garden than usual this spring? Gardens that are over-watered and over-fertilized can also make garden plants more enticing to aphids.

Furthermore, there are a few types of plants that are highly attractive to aphids, like nasturtium and mustard plants. However, planting these types of plants in your garden may not be a bad thing, as they can instead attract aphids and keep them on those plants and away from your other ornamental plants and vegetation.

Of course, these are only a few reasons you may have more aphids in your garden than usual. Weather conditions could play a part in the aphid population as well as a lack of natural predators in your garden like ladybugs or lacewing bugs.

That being said, keep in mind that a number of pests and problems can cause a deterioration of plantlife. Before you work on methods for how to get rid of aphids, let’s first make sure you have an aphid problem.

How To Get Rid Of Aphids – Identifying An Aphid Problem

Aphids are a common garden pest, but they are not the worst of garden pests and may not be to blame for your garden issues. Are you sure you are dealing with aphids? Before you choose your methods for how to get rid of aphids in particular, let’s take a look at a few telltale signs that aphids are the insects plaguing you.

You probably have aphids in your garden if you:

  • Physically See Aphids In Large Groups

Though aphids are extremely small and sometimes difficult to see with the naked eye, they often feed together in large colonies that are easy to spot if you take a look. Examine your plants closely, paying special attention to leaves, stems, and roots.

Look beneath leaves as well and watch for clusters of small insects. Remember, aphids can be several different colors depending on their species, and while nymphs are generally smaller than adults, they do not grow larger than 1/4th of an inch long.

  • Notice Damaged Leaves

Aphids cause damage to leaves and plant life that lead to misshapen or discolored growth. If your plants have curled leaves, leaves that are yellowish, stunted, or otherwise abnormal, you likely have aphids.

  • Find Leaves and Stems That Are Covered in Something Sticky

Honeydew isn’t just the name of a tasty melon. It’s also the name of aphid waste, and this waste is a sticky substance that is a result of the aphid’s diet. In a large aphid infestation, plants can be covered in this sticky substance. Honeydew can also attract other insects like ants and pests who are attracted to sweet, sugary substances.

  • Find “Sooty Mold” On Your Plants

Honeydew as a result of aphid waste can encourage a fungal growth on plants that is called sooty mold. As its name suggests, sooty mold is thick and black, and can grow on plants and make them look as if they are covered in soot.

  • Notice Deformed Flowers and Fruits

If your flowers or fruits are growing but are not looking quite right, you probably have aphids. When aphids feed on young plants, this can result in the plants growing up to be deformred or distorted.

  • Discover Galls On Roots and Leaves

Galls are a structure made on plants by different types of insects, including aphids. Galls are often created as a type of habitat for aphids to live in or have offspring inside. These structures can look almost as if they are part of the plant themselves, or can appear web-like.

  • Notice An Abundance of Other Insects You Did Not Introduce Into Your Garden

Many people purposefully introduced predatory insects like ladybugs to help control aphids. However, if you notice a large number of predator insects like ladybugs or Asian lady beetles who feed on aphids that you did not introduce to control these pests, then you’re likely dealing with those pesky, sap-sucking bugs.

Another sign of aphids is a large number of sugar ants. Ants and other pests can be attracted to the honeydew that aphids secret in their waste, as we mentioned above.

  • Sick or Dying Plants 

Aphids are known to transmit viruses from plant to plant, which can result in serious destruction of gardens if not controlled and taken care of early on. In fact, it takes less than one minute for an aphid to feed on a plant and transmit a virus.

If you notice plants dying in your garden and have also noticed any of the above signs of aphid activity, it is time to look into how to get rid of aphids.

There are insecticides that can be used on gardens that will not harm plants, but keep in mind that many insecticides can use harsh chemical ingredients that are harmful to people, pets and the environment and should therefore be used only as directed and with caution.

How To Get Rid Of Aphids Using Professionals

That said, sometimes a large aphid infestation can lead to other problematic insects in your garden. These infestations can quickly get out of control and lead to other issues.

Ladybugs can be an attractive and effective deterrent for aphids.

Chances are, if you like organic gardening and using natural products for how to get rid of aphids, then you’ll probably be interested in learning about some home remedies you can use to control the problem as well.

One of the things we like best about using home remedies for how to get rid of aphids is that doing so saves money. Of course, home remedies for how to get rid of aphids may require a bit more time and commitment on your part, but it can be worth it in the end.

A few home remedies, ingredients and recipes you can use for how to get rid of aphids on your own at home are listed below:

Water Spray 

Aphids can be removed by spraying your plants down when you water them with cold water and a hose. You can add extra pressure to the hose by holding your thumb over the hose head or adjusting the pressure on your hose head using an attachment.

Doing this will knock the aphids from the plants, often sending them on their way to find another food source. Remember, aphids don’t have the best sense of direction and typically will not be able to find their way back to the plant they were originally feeding on.

Introduce The Natural Predators 

Ladybugs are famously known for being beneficial garden insects and are natural predators of aphids. You can introduce ladybugs by purchasing them at most garden stores or online. Of course, make sure you are introducing benfidical lady bugs and not their close cousin, the Asian lady beetle, who looks similar but can be destructive.

Other natural predators of aphids include green lacewings, parasite wasps, and different species of birds.

Essential Oils

Wondering how to get rid of aphids using essential oils? It’s totally possible!

Aphids are sensitive and can be repelled and even killed by a number of essential oils including peppermint oil, neem oil, clove oil, rosemary oil, thyme oil, garlic oil, and citrus oil.

You can make your own essential oil spray for how to get rid of aphids by adding five to ten drops of the oil of your choice to two cups of water in a spray bottle and spraying the affected area of the plant.

That said, before you spray the plant with any essential oil sprays, make sure to do your research as some essential oils may be harmful to particular plant species.

Soap and Water Spray

Using liquid dish soap and water to spray aphids is a popular and simple method you can use for how to get rid of aphids at home. We recommend using a liquid dish soap like castile, as it does not contain any degreasers, detergents or moisturizers which can harm plants.

Drop a few drops of your liquid dish soap into two cups of water and mix it until it is sudsy. Then mix the solution into a spray bottle and spray it directly on affected plants. You can also open the bottle or use a small bowl to soak affecte leaves in the solution for a few moments to ensure you get any eggs.

How To Get Rid Of Aphids Using Insecticides

Insecticides may be needed in very large aphid infestations.

While aphids are generally easier to control than some other types of garden pests, very large aphid infestations may require the use of insecticides. That said, some  insecticides commonly used to control aphids can contain harsh chemical ingredients that can be harmful to people, pets and the environment.

Furthermore, insecticides may also be harmful to beneficial insects like honey bees, ladybugs and butterflies.

However, when used correctly, insecticides can work well to control an aphid infestation. Let’s take a look at some of the top recommended insecticides experts suggest you use for how to get rid of aphids below.

Tips On Preventing A Future Aphid Infestation In Your Garden

Prevent future aphid infestations by practicing routine garden and yard care.

Since aphids are so common and reproduce so rapidly, it may be difficult to keep them out of your garden altogether. With that being said, you can implement some preventative strategies to help control an aphid population and keep them from becoming an overwhelming problem.

A few ways you can monitor and control future aphids in your garden include methods listed below:

Companion Planting

Aphids may be attracted to a number of different plant species, but they are also just as equally repelled by certain plants. You can use both types of plants to your advantage by implementing companion planting throughout your garden.

Use plants aphids are attracted to like mustard and nasturtium as trap plants to attract aphids and keep them away from your garden plants like roses, peas, and cabbage. However, you are not providing trap plants to aphids for them to enjoy. You should check these plants regularly and treat them to get rid of the aphids before they jump to other plants in your garden.

You can also plant repellent plants like catnip, garlic, and chives to protect plants like roses, peas, lettuce and more.

Encourage The Predators 

Ladybugs, lacewings, and birds may fly off once introduced to your yard or garden after a few days if conditions are not ideal. In order to control aphids and keep predators around, try making sure the predators benefit from staying in your garden.

Put up birdhouses and bird seed to attract birds, and provide ladybugs you introduce with ladybug houses. Spray your garden with water to give ladybugs droplets to drink from, and make sure you are reintroducing them routinely if they fly away and the aphid population begins to spike again.

Spray Dormant Horticultural Oil On Plants During Winter

Once you have managed to figure out how to get rid of aphids, we suggest spraying down your garden and trees with a dormant horticultural oil to kill any eggs that are overwintering on your property. This will help prevent a future infestation in the spring.

Avoid Over-Fertilizing or Over-Watering Your Garden

Remember, over-watering and over-fertilizing your garden can make plantlife more enticing to aphids. Doing this can also lead to other problems in your garden and a decrease in healthy plant-life.

Only water and fertilize your garden as needed in order to control an aphid population and keep other pests from getting out of control as well.
