Soap, that is made from sodium/potassium salt of fatty acid, can be categoried as a general household detergent just as dish-washing detergent, shampoo and powder laundry detergent which have anionic surfactant property. Besides the fundamental benefit of removing dirt from surface, soap water has been referred to for its insecticidal activity for more than 200 years. Today, countries in Europe, America and Australia make use of this property of soap by producing many kinds of insecticidal soap products that can get rid of insect pests of home ornamental plants. Nevertheless, in Thailand, the concept of using anionic surfactant of various diseases, is still new.
Entrusted with the duty, and realizing the people’s tendency in overspending on pesticides and neglecting other methods for insect vector control, the Chemical Control Section, Medical Entomology Group, National Institute of Health, Department of Medical Sciences has experimented, applied and developed the simple prepared general household detergents as a weapon against mosquito and other insect vectors around the house. This may prevent epidemics borne by insect vectors before wide spread to the nearby community. Consequently we expected to change insecticides and turn to using novel household weapon in controlling insects for good health, safe from insect-borne diseases, and for life long clean environment in which to live in.
