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.The impregnated member is slidably introduced into the channel through end open end thereof and when the volatilizable substance is exhausted, the member is ejected from the channel by the insertion of a new member into the channel. | |
