ABSTRACT:
Disclosed herein are burnable air treatment chemical dispensing substrates, such as mosquito coils, in which wax is incorporated. In one form the wax portion is a separate coating layer in which the air treatment chemical is also placed. This permits the underlying base to be dried without loss of air treatment chemical. Methods for forming such coils are also disclosed.
