DIY Insecticidal Soap: Your Secret Weapon Against Garden Pests

Welcome back to Farm to Table Living, where we empower you with practical tips and tricks for maintaining a thriving garden. In this article, we're excited to share a simple yet effective DIY method for creating insecticidal soap. This natural solution will become your secret weapon in combating various garden pests, including those pesky squash bugs. Get ready to say goodbye to unwanted invaders and hello to a healthier, pest-free garden!

Insecticidal soap is a safe and natural alternative to conventional chemical insecticides. It consists of a solution made from mild soap and water, which works by suffocating and dehydrating soft-bodied insects. It's an excellent choice for organic gardeners seeking to control common pests while minimizing harm to beneficial insects and the environment. Insecticidal soap is effective against a wide array of garden pests. Here are some common ones you can combat using this natural solution:

  1. Aphids: These small, sap-sucking insects can wreak havoc on various plants, causing distorted growth and the transmission of plant diseases.

  2. Whiteflies: Tiny, white insects with a waxy appearance; whiteflies cluster on the undersides of leaves and extract sap, leading to stunted growth and yellowing foliage.

  3. Mealybugs: Mealybugs are small, soft-bodied insects covered in a white, cotton-like substance. They feed on plant sap, causing wilting and yellowing of leaves.

  4. Spider Mites: These tiny arachnids pierce plant cells and suck out the sap, resulting in yellowing leaves, stippling, and the formation of fine webbing.

  5. Thrips: Thrips are slender insects that feed on plant sap, causing leaves to become distorted, discolored, and eventually die.

  6. Squash Bugs: As discussed in our previous article, Squash bugs can be effectively controlled using insecticidal soap. Their feeding habits and damage to squash plants make them a prime target for this natural solution.

Let's get down to the fun part: making your own insecticidal soap. Follow this simple recipe to create a powerful pest control solution:


  • 1 tablespoon of mild liquid soap (such as castile soap or dish soap, preferably Dawn dish soap)

  • 1 tablespoon of vegetable oil (Alternatively coconut oil, olive oil, or grapeseed oil.)

  • 1 quart (4 cups) of water


  1. Combine the mild liquid soap, oil, and water in a spray bottle or garden sprayer.

  2. Gently swirl the mixture to ensure the soap is thoroughly dissolved.

  3. Your insecticidal soap is now ready to use!

To effectively utilize your homemade insecticidal soap, follow these guidelines:

  • Test on a small portion of the plant before applying it to the entire plant to ensure it does not cause any adverse effects.

  • Apply the solution directly to the pests, ensuring thorough coverage of all affected areas, including the undersides of leaves.

  • Avoid spraying during the hottest part of the day to prevent leaf damage from the sun's intense heat.

  • Repeat the application every few days or as needed until the pests are under control.

Congratulations! You are now equipped with a powerful tool to combat various garden pests – insecticidal soap. You'll witness a remarkable transformation in your garden by following this simple DIY recipe and applying it to pests like squash bugs, aphids, whiteflies, and more.
