Disclosed herein are wearable devices (10) for dispensing insect repellents, fragrances, and/or other chemicals along the outside of the clothing of a human, to avoid the need to apply such chemicals directly to clothing or to human's skin. The devices have an on/off switch (18) that automatically controls a shutter (40) which enables and restricts air flow, while also controlling fan (21) operation and covering of a use-up cue (66). The device also is designed to prevent fan operation when an impregnated slab (60) is not present. Also disclosed are preferred refills for use with such devices.
