Homemade Aphid Spray Recipes

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.


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

Like dish washing 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.
