Repellents: Integrating Sensory Modalities

Recommendations for managing wildlife damage situations often involve application of multiple methods or techniques. The basis for such recommendations is unclear as there is little evidence that such combinations of methods work more effectively than the individual methods alone. In order to improve beyond hit or miss repellent applications, we should adopt principles exhibited in nature and develop repellent treatments based on the design of signals used in animal communications. In particular, characteristics that increase detectability, discriminability, and memorability should be identified and incorporated into repellent design. To do so, the sensory capabilities of the target species need to be more completely understood.
