A device for dispensing a thermally volatilizable substance in which a housing is formed with a linear open-ended, open top guide channel extending across the upper portion thereof. A window is formed in the floor of the channel and a heater is disposed below the window, providing a support for a member impregnated with the volatilizable substance. A grid spans the open top of the guide channel above the window in juxtaposition therewith to permit release of the substance, e.g. an insecticide, while a skid or runner-shaped element carried by said grid presses the member against the heater.
