The portable insecticide dispenser is an electromechanical device. The portable insecticide dispenser vaporizes an insecticide using a method selected from the group consisting of evaporation and sublimation. The portable insecticide dispenser diffuses the vaporized insecticide into the atmosphere. The portable insecticide dispenser comprises a housing, a control circuit, and an essential oil. The housing contains the control circuit and the essential oil. The essential oil is a lipid-based substance that contains a substance known to be an insecticide. The control circuit vaporizes the essential oil such that the insecticide forms a gas phase that mixes into the atmosphere. The control circuit further mechanically diffuses the gas phase of the insecticide into the atmosphere.
