An apparatus and method are provided, which enable an air modifying agent such as an insecticide, pesticide, insect repellant, fragrance, perfume etc. to be disseminated into an atmosphere. The air modifying agent is entrained in a flammable liquid carrier (2) which is less volative than the agent, which is held in a container (1). A wick (3) draws the agent/carrier (2) up to an igniting station provided at the rim (5) of a metal collar (4) which closely encircles the wick (3). The collar (4) is provided with a pair of diametrically opposed elongate slots (8), which expose part of the wick (3) to the atmosphere and thereby provide a vaporisation station spaced below the igniting station and disposed in the path of the flammable liquid carrier. In use, heat from a flame (6) passes along the collar (4) and warms the wick (3) in the vaporisation station, thereby assisting the preferential evaporation of the air modifying agent from the vaporisation station, away from the flammable liquid carrier prior to the latter's combustion in the flame (6). An angled deflecting plate (10) is also provided to deflect the evaporated air modifying agent away from the flame (arrow A).
