Disclosed herein are mats for dispensing volatile vapors such as insecticides. The mats are multi-layered. One layer is a carrier layer impregnated with the volatile. It is secured to at least one metal layer. The metal layer spreads the heat from a heater, thereby minimizing hot spots. In other embodiments additional layers are provided to provide a further heat distribution or temperature step down. An air gap can be provided between two of the layers.
