Abstract
An environmentally-safe, broad spectrum insecticide that is toxic to invertebrate animals and non-toxic to vertebrate animals. The insecticide comprises a water solution of hydroxy acyclic acid, such as citric acid, and ionic or non-ionic surfactant thoroughly mixed together. The insecticide may be applied by aerosol, misting, spraying, or pouring on the insects or into their abodes. The composition is also an effective mosquito repellant when applied to human skin.
Claims21
