Supplies: castile soap, water, essential oil of lemon, spray bottle
Expense of Manufacturing: $10*
It’s imperative to protect your prized plants from creepy crawlies, but it can be challenging to locate an insecticide that doesn’t also harm everything else in its path. Many commercial insecticides contain harsh chemicals that can be detrimental to the environment, beneficial insects, and even the plants themselves. Fortunately, making your own non-toxic insecticidal soap to mist on plants is a simple and effective solution.
To create this homemade insecticidal soap, you will need the following ingredients:
1. One quart of water
2. One or two drops of lemon essential oil
3. One tablespoon of pure liquid soap (such as castile soap)
Here are the steps to prepare and use your non-toxic insecticidal soap:
1. **Combine the Ingredients**: Start by combining one quart of water with one or two drops of lemon essential oil. The lemon essential oil not only adds a pleasant fragrance but also has natural insect-repelling properties.
2. **Add the Liquid Soap**: Next, add one tablespoon of pure liquid soap, such as castile soap, to the water and essential oil mixture. It’s important to use pure liquid soap because dish soap can ruin plants and is ineffective against bugs. Castile soap is a gentle, vegetable-based soap that is safe for plants and effective at controlling pests.
3. **Transfer to a Spray Bottle**: Once all the ingredients are well-mixed, transfer the blend into a clean spray bottle. Make sure the spray bottle is thoroughly rinsed to avoid any residues that could harm your plants.
4. **Application**: To keep annoying insects away from your plants, spray the contents of the container on the affected areas. Be sure to cover both the tops and undersides of the leaves, as insects often hide in less visible spots. Apply the spray in the early morning or late evening to prevent the soap from evaporating too quickly and to avoid potential sunburn on the leaves.
5. **Reapply as Needed**: Reapply the insecticidal soap every few days or after it rains, as rain can wash away the solution. Regular applications will help maintain its effectiveness in repelling insects.
By using this homemade non-toxic insecticidal soap, you can effectively protect your plants from pests without harming the environment or beneficial insects. This simple, natural solution is not only cost-effective but also ensures the health and safety of your beloved plants.
