U.S. government work.


White-tailed deer (Odocoileus virginianus) damage urban and suburban plantings, as well as crops and stored feed. We tested the efficacy of a frightening device that played pre-recorded distress calls of adult female white-tailed deer when activated by an infrared motion sensor for a period of 13 days. This deer-activated bioacoustic frightening device reduced deer entry into protected sites by 99% (δ = -558, P = 0.09) and bait consumption by 100% (δ = -75, P = 0.06). The frightening device that we evaluated demonstrated potential for reducing damage in disturbed environments and agricultural settings.
