How to Use Dr. Bronners As Insecticidal Soap

Organic gardeners know the value of insecticidal soap. Made from plant material and animal fat, it is safe to use in the garden as well as indoors. It acts by washing away the protective coating on an insect's shell causing dehydration and death. Insecticidal soaps will kill aphids, mealybugs, whiteflies and spider mites, while sparing beneficial insects such as ladybugs. According to scientists at Washington State University, good coverage of the plant with the soap is essential, and you should spray your plants in the early morning or evening to avoid evaporation of the droplets on the leaves. Many gardeners are discovering how easy it is to make insecticidal soap, using Dr. Bronner's soaps as a base. Dr. Bronner's Magic Soaps is a 60-year-old company that manufactures certified organic soaps, hair products and shaving gels.
