Abstract: An insect repellent system includes an active insect repellent ingredient and a glycol solvent as part of a thermally activated dispersion using a wick and a heater. The active ingredient may be a pyrethroid insecticide or a natural insect repellent material. The glycol solvent includes at least two hydroxyl groups and may be a mixture of glycol solvents. In one solvent mixture, a combination of hexylene glycol and dipropylene glycol are combined with a pyrethroid insecticide of either metofluthrin or transfluthrin. The insect repellent system may be a portable insect repellent system formed from thermoplastic materials and rely on battery power to generate heat.
