<p>Disclosed herein are mats (10) for dispensing volatile materials. The mats include a central depression (18) and a moat (20) surrounding the central depression. A first volatile is provided in the central depression and bleeds into a portion of the mat between that depression and the moat. A second volatile is provided outside of the moat. The moat acts to prevent bleeding of the volatiles between portions of the mat. The volatiles are selected to provide an immediate short-term impact on the environment, followed by a long-term separate impact.</p> |
