Controlling Aphids: 8 Homemade Aphid Spray Recipes and Tips (2024)

Creating my own aphid spray is easy and inexpensive.

  • I grab a few tablespoons of liquid dish soap.
  • I dilute it with a pint of water to create the solution.
  • I fill a squirt bottle with the mixture.
  • I gently wipe the soapy solution onto plant leaves with a sponge.
  • I make sure to hit the undersides where aphids often hide.

For the most effective and budget-friendly homemade aphid spray, I’ll start with dish soap and water because these are items I usually have at home. First, I mix a few tablespoons of liquid dish soap with a pint of water.

This creates a soapy solution that is deadly to aphids but safe for plants and beneficial insects when used correctly. I then pour this mixture into a squirt bottle for easy application.

Instead of spraying the plants directly, I use a sponge to apply the soapy water to the leaves, especially the undersides, where aphids like to congregate. This method allows me to be precise, targeting just the aphids and not harming any helpful insects in my garden.

This solution is not only effective and cost-efficient but also ensures that my garden remains a healthy environment for both plants and beneficial insects. Plus, it’s a quick fix that I can easily repeat as needed.

If you have a vegetable garden, you most likely have aphids, too. The small insect pests, known as “plant lice,” feed off plants by attaching to the leaves or base of the entire plant and sucking out the nutrients, causing the plant to wither, yellow, or curl at the leaves.

Aphid populations reproduce so quickly that by the time you figure out the problem, they’ve already infested your garden and potentially infected your plants and rose bushes with lethal viruses.

You can fight off these natural predators with a homemade aphid spray, but the question is how to make them yourself. Using something as simple as liquid dish soap, you can get rid of these apex rose killers today.

DIY Sprays vs. Chemical Sprays

Some people choose to plant gardens full of beneficial fruits and vegetables to feed their families. Using chemical pesticides to remove pests would negate any health benefits hoping to be gained.

Others might plant flowers that they use to create a fragrant home, potentially transferring harmful chemicals from the garden to their home. Numerous natural and organic substances can be mixed to form a natural aphid spray to kill invasive aphids, lace bugs, and parasitic wasps.

Making Your Own Aphid Sprays

Soap and Water

A few tablespoons of liquid dish or insecticidal soap diluted in a pint of water is the simplest way to make a natural aphid killer spray for that aphid infestation. After mixing the water and soap mixture, fill up a squirt bottle, take a dish sponge and head out to your garden.

Your first thought might be to indiscriminately spray all the plants in your garden with the dish soap spray bottle. However, doing so will kill any beneficial insects along with the aphids.

Instead, to control aphids but not lose your good bugs, spray the soapy water onto the sponge and gently wipe it on the leaves of the plants. Be sure to check underneath the plant leaves for eggs and larvae.


Castile soap is a versatile all-natural, vegetable-based liquid soap with olive and mineral oil as the main ingredients. When combined with vinegar and water, Castile makes a DIY natural aphid spray. The vinegar deters future garden pests from invading your new growth.


Organic Pesticide – Vinegar Spray Recipe

  • 1 tablespoon Castile soap
  • 1 tablespoon white vinegar
  • 1 gallon of water


Like dishwashing soap, vinegar is lethal to all insects, whether they are the Japanese species of aphids you are trying to get rid of or the good bugs you need in your garden. Use a spray bottle to spray the tops and bottoms of the leaves lightly.

Neem Oil

Pure and organic Neem oil can be used to repel aphids, cabbage worms, and other pests, as well as help control any fungi they transfer into your garden. Simply mix Neem oil for plants with a few drops of liquid dish soap and fife cups of water.


Neem Oil Based Spray for Aphids

  • 1 tbsp neem oil
  • 1/3 tbsp liquid dish soap
  • 5 cups of water


Once you dilute the Neem oil, use a garden hose sprayer to mist your garden with the mixture in the early morning. Neem oil doesn’t have any harmful effects on beneficial insects, but it does help in repelling aphids, mosquitoes, and other pests.

Spray this solution on all your plants, from the tomatoes and cucumbers in the vegetable garden to flowers like roses and milkweed to the base of trees to repel unwanted aphids and other pesky insects. Your plants will thank you for ridding them of these life-sucking creatures!

Essential Oils

Essential oils have long been used in aromatherapy but are recently becoming popular in many aspects of the home, including pest control for gardens. A mixture of thyme, peppermint, cloves and rosemary oils create a potent mix that will kill and repel aphids.

If you have outdoor or stray cats who routinely enter your garden, peppermint oil is one of the essential oils that are known to be potentially toxic to cats. On the other hand, cats dislike the scent of rosemary, which can make it a digging deterrent.

Using Tomato Leaves

Toxic compounds called alkaloids are found in the leaves of tomato plants. These tomato leaves can be chopped, soaked in water overnight, drained and diluted with water in a spray bottle to create a natural aphid killer.

Unless you are allergic to tomatoes, this recipe isn’t dangerous for humans or plants. Directly spray the leaves and undersides of plants in your garden to kill the harmful plant lice.

Garlic Oil Mix

Garlic isn’t just used to repel vampires. The sulfur in garlic is toxic to pests. It also kills ladybugs and other beneficial insects. For that reason, this garlic-based natural aphid spray should only be used if you don’t have any essential bugs in your garden.


Garlic Oil for Killing Aphids

  • Several cloves of garlic, minced
  • 4 teaspoons of vegetable oil
  • 1 pint of water
  • 1 teaspoon dish detergent
  • Spray bottle


Add garlic to the vegetable oil and let it infuse for 24 hours. Strain the garlic and add oil to water and dish detergent. Mix well and spray on bugs for a natural aphid killer.

Getting Rid of Spider Mites

Spider mites are another tiny pest that can cause big problems in your garden. If the leaves of your plants are dry, brittle or falling off, you might be dealing with a spider mite infestation.

The insects are tiny and cause immense damage to healthy plants quickly by poking holes in the leaves and extracting the water and nutrients that are the lifeline for your plants.

Neem oil is one practical solution for getting rid of spider mites. Follow the directions above by diluting neem oil with water and spraying on the leaves and the undersides of leaves to repel the mites.

DIY Prevention Strategies

As Ben Franklin said, “An ounce of prevention is worth a pound of cure.” He was talking about fire safety, but it is often applied to health safety. Or in this case, garden safety. There are a few things you can do to prevent invasive insects such as aphids or spider mites from infesting your garden.

Attract Favorable Bugs

Lady beetles and lacewings are two insects that feed on aphids. Introducing them to your garden is a natural selection way to combating their infestations while keeping the beneficial bugs safe from chemical pesticides.

There are two main ways to get the “good” bugs; acquire them at gardening stores or turn your garden into a habitat with an ample supply of nectar to attract the helpful kind of insects.

Apply Dormant Oil

Dormant oil is a mixture of several oils and water that is applied to plants during their dormant season to repel aphids after the wintering is over. The mixture shouldn’t harm beneficial insects because they won’t be the plants during the inactive phase.


DIY Dormant Oil for Controlling Aphids

  • 1 gallon of water
  • 1 tablespoon baking soda
  • 2 tablespoons of canola oil
  • Spray bottle


Combine water and baking soda with canola oil. Pour the mixture into a spray bottle and mist onto the leaves and undersides of the dormant plants.

Plant Fragrant Herbs

Some herbs are so fragrant that their smell repels aphids and other harmful pests. Planting these herbs throughout the garden can naturally prevent aphids from infesting your plants.

Oregano, garlic, and chives are three herbs that are effective in repelling aphids. Cayenne peppers are also known to successfully prevent critters and insects if you like peppers with some kick.

You can sprinkle natural diatomaceous earth on the insects since it sticks to them and causes them to dry out, leaving you “aphid-free.”

How Does Your Garden Grow? Mother Goose asked this question in a child’s rhyme game. After you’ve tried these natural aphid sprays, you can answer that your garden grows harmoniously.
