2 Homemade Aphid Sprays For Vegetables And Plants

You can control aphids, those pesky, troublesome pests we find on houseplants and in the landscape with a homemade aphid spray.

Equipped with delicate, tuber-like piercing/sucking mouth parts, aphids enjoy young, tender tips of new developing plant growth, hanging out on the undersides of leaves and clustered or in colonies on stems.

Organic gardeners have used homemade sprays in fighting and controlling aphids for generations. Below you’ll find two homemade organic aphid sprays made from tomato leaves and another from garlic.

Knowing how to make and use them is important, but understanding why they work is equally important. Check out these two organic, homemade aphid sprays.

Organic Aphid Spray Made With Tomato Leaves

The tomato plant a nightshade family member, contains alkaloids – toxic compound found in their leaves.

Chopping the leaves releases the alkaloids. When diluted and suspended in water, they make an easy-to-use homemade spray for fighting aphids. A spray safe for the environment, plants, and humans.

Making The Tomato Leaf Spray

  • 1-2 cups of tomato leaves
  • Cheesecloth or a strainer
  • Two cups of water
  • Spray bottle

To make the spray, soak 1 or 2 cups of chopped tomato leaves overnight (depending on the concentration that you require) in two cups of water. Using the fine strainer or cheesecloth strain the leaves out of the mixture. Add an additional two cups of water and add it all to the spray bottle.

Applying The Tomato Aphid Leaf Spray

When battling aphids completely spray the foliage and stems of infested plants. Make sure to cover the undersides of the leaves as aphids congregate in those areas.

Caution: While safe for plants and humans, some people are allergic plants in the nightshade family. If you’re allergic to them take care when applying this homemade aphid spray.

Aphid Garlic Oil Spray

As a pest-fighting spray garlic mixtures have been used for many years. Garlic contains sulfur which is anti-fungal and anti-bacterial but also toxic to most pests. When combined with dish soap the mixture breaks down soft-bodied pests.

Making A Garlic Oil Spray

  • 3-4 cloves of garlic
  • Cheesecloth or strainer
  • Mineral oil
  • Spray bottle
  • Water
  • Liquid dish soap (I like Castile soap)

To make the spray, finely chop or mince all the cloves of garlic and add the garlic to 2 teaspoons of mineral oil. Allow the mixture to sit for 24 hours before straining the mixture.

In one pint of water add the remaining liquid. When spraying, mix two tablespoons of the concentrate to 1 pint of water in the spray bottle

Applying The Garlic Oil Spray

Conduct a test-spray in a small area on one part of a plant to make sure the spray does not injure the plant. If you don’t notice any damage or yellowing of leaves after a day or two, you ahead and spray the entire plant while paying close attention to the undersides of the leaves.

Caution: By being a non-selective insecticide, garlic oil can harm beneficial insects such as ladybugs. Therefore, used it where no beneficial insects “live” in your garden.

These organic sprays are effective, low in cost and safe for the environment.
