Are you looking for a garlic aphid spray to keep these soft-bodied menaces out of your garden? This article gives you a few options to consider, along with additional information about studies done using garlic extract for aphid control.  

How to Make Garlic Aphid Spray for Garden Use

There are no hard and fast rules to making your own garlic aphid spray. In fact, you can get as creative as needs be to put your own concoction together to oust aphids from your garden. Let’s look at different alternatives to making a garlic aphid spray.

Basic Garlic Aphid Spray

For this spray, you’ll need the following items:

  • Cloves of garlic
  • Water
  • Spray bottle

This is the most common garlic-based spray. To make, collect 20 cloves of garlic. Slice cloves thinly or crush. Add your sliced or crushed cloves of garlic to 1 liter of water. Allow the water and garlic mixture to sit for a few hours to come together.

Have you ever thought about the eating habits of aphids? You may be interested in this post. The writer speaks extensively about aphids and what they eat and the strange relationship they share with ants. You have to know your enemy to beat them, right?

Apply to the soil, leaves, and other areas in your garden.

As a result of the pungent, unpleasant aroma of garlic, it’s highly repelling to aphids. This simple spray will help to keep aphids at bay.

Since this spray won’t kill aphids but merely repel them, you need another option to deal with an already infested garden. Let’s look at another garlic aphid spray alternative.

Note: While this mixture calls for a liter of water, the spray bottle doesn’t have to be that size. This is because you’ll be mixing in one container, and transferring what you need to use to the spray bottle. If you have any spray bottle lying around, that can be used. If you don’t here are a few options:

Garlic Aphid Spray with Neem Oil

For this spray, you’ll need the following items:

  • 20 cloves of garlic
  • 100 ml mineral or neem oil
  • 2 liters of water
  • Spray bottle

This garlic aphid spray is an improvement to the previous. In addition to repelling aphids, this concoction kills them through a smothering process, because of the addition of neem or mineral oil.

Chop or crush garlic and allow to seep in mineral or neem oil. Add your water. Transfer to spray bottle when ready to use.

For neem oil options, the following suppliers are recommended:

Garlic Aphid Spray with Neem & Castile Soap

Unlike the other garlic aphid sprays, you’ll need a bit more for this one.

The ingredients are:

  • 20 garlic cloves
  • 100 ml mineral or neem oil
  • 10 ml castile soap
  • 2 liters of water
  • Spray bottle

The soap addition to this garlic aphid spray helps to break down the aphid’s exterior which causes dehydration and eventually death.

Follow the process outlined for the garlic aphid spray with neem oil, and then add your liquid or castile soap.

Castile soap is always a preference, as it’s made using natural, organic ingredients. To add, some suppliers add essential oils like peppermint to their castile soap, which is great for garden use.

The following castile soaps are recommended:

Important Information to Consider

Garlic extract has been used in a study to determine how aphids would react to it. The study concluded that garlic can indeed be used in a push-pull strategy to control aphids. The push-pull strategy uses garlic to repel (push) aphids from your garden, while attracting beneficial insects like lacewings and lady beetles.

This strategy is indeed effective because a double tactic is being used against aphids. If you wish to learn more about this study, please click here. If you’re also thinking about using companion plants to control aphids, read this article.

  2. Since not all the contents of the spray will be used up in a single spraying session, is there a way to store this? Thanks.

  3. Great study information added to the article. I knew garlic was a good repellent, but had no idea studies were actually performed to see how effective it really was. Thanks for that bit of info.
