Moisture and malodor control systems are disclosed. These systems provide moisture control and the sustained delivery of active volatile compounds for imparting fragrance and controlling malodor within innumerable objects and spaces, such as shoes, gloves, closets, etc. The systems utilize a novel combination of active volatiles contained within a diluent carrier and solid adsorbing compound. In some embodiments, increased release of active volatiles is triggered by the presence of moisture in the target environment. The systems of the invention may further include an accessory component for providing fragrance to the target environment and/or an accessory component for absorbing and removing malodorous compounds from the target environment.
