Insecticidal soap is a safe, easy way for the homeowner and the gardener to control gnats [Dipterid suborder]. It may be homemade or store bought. Some people may find this natural insecticide an irritant to the eyes or skin. But basically, insecticidal soap is considered to be of low toxicity and irritability to mammals.
