Disclosed are holders for supporting a burnable substrate such as a mosquito coil. They have an ash tray, a mounting post coupled to the ash tray and moveable between a storage position wherein both an outward part and an inward part of the mounting post are adjacent the ash tray and an erected position where the mounting post is suitable to support the burnable substrate, and a locking bracket linked to the ash tray which is suitable to retain the mounting post in the erected position when that is desired. In some forms multiple such coils and holders are housed in a compact kit.

Devices for dispensing air treatment chemicals are described. They have a first substrate bearing a first volatile air treatment chemical that is dispensed when the first substrate is heated, and a second substrate bearing a second volatile air treatment chemical that is dispensed from the second substrate when the second substrate is heated. The substrates are positioned in stacked fashion relative to each other, optionally with a permeable membrane there between. There may also be a use-up cue indicator unit coordinated with use of the chemicals. The first and second substrates and indicator unit can be in a single replaceable cartridge unit, preferably with the second substrate in the form of a porous ring that houses the indicator unit.
