A non-powered insect repellent device includes a heating element, a reservoir, and an activating member. The heating element includes a chemical compound configured to generate heat via an exothermic reaction when exposed to air. The reservoir is coupled with the heating elements and includes a dosing member and a container. The container included a cavity containing a volume of insect repellent material. The activating member is coupled with the heating element and the reservoir. With the activating member in a closed position, the activating member prevents air from passing to the chemical compound and prevents the insect repellent material from being dispensed from the cavity to the dosing member. With the activating member in the open position, air passes through the first opening to the chemical compound to facilitate the exothermic reaction and the insect repellent material is dispensed to the dosing member.
