Abstract
Disclosed herein is two-stage mat for dispensing volatile materials. The mat is comprised of two materials varying either in thickness, thermal conductivity and/or porosity (and coated with like volatile material), or coated with volatile materials having different vaporization pressures. In either configuration, the mat provides for both an instant burst of volatile and then a sustained vaporization of volatile. Methods of using such mats are also disclosed.
