Insect repellent device and method

A non-powered insect repellent device, comprising:

• a plurality of stacked heating elements, each including a chemical compound configured to generate heat via an exothermic reaction when exposed to air via a first opening;
• a container thermally coupled with the plurality of stacked heating elements, the container including a cavity containing a volume of insect repellent material and a second opening, the insect repellant material including a metofluthrin solution;
• a dosing layer including an absorbent material, the dosing layer coupled with the container and configured to receive at least a portion of the volume of insect repellent material from the cavity via the second opening;
• a first activating member coupled to the first opening and configured to selectively permit air to flow to the outer-most heating element via the first opening to facilitate an exothermic reaction;
• and
• a second activating member coupled to the second opening and configured to selectively dispense insect repellent material from the cavity to the dosing layer via the second opening.

A non-powered insect repellent device, comprising:

• a housing defining a cavity;
• a heating element including a chemical compound configured to generate heat via an exothermic reaction when exposed to air via a first opening;
• a reservoir thermally coupled with the heating element, the reservoir including a dosing member, a container cavity containing a volume of insect repellent material, and a second opening, the dosing member positioned to receive at least a portion of the volume of insect repellent material from the container cavity via the second opening;
• an activating member coupled to the first opening and the second opening, the activating member configured to selectively permit air to flow to the outer-most heating element via the first opening to facilitate an exothermic reaction and to selectively dispense insect repellent material from the container cavity to the dosing layer via the second opening;
• and
• an insulative layer surrounding at least a portion of the heating element;
• wherein the heating element, the reservoir, the insulative layer, and at least a portion of the activating member are positioned within the cavity of the housing.
