Use repellents that taste bad (‘contact repellents’) to deter crop or property damage by mammals to reduce human-wildlife conflict
A replicated, randomized, controlled study (year not stated) in a woodland in Oxfordshire, UK (Baker et al. 2005) found that treating corn cobs with the repellent, ziram, reduced the rate of its consumption by European badgers Meles meles. Fewer corn cobs treated with ziram were damaged by badgers (39–63% of cobs) than were untreated cobs (82% of cobs). Among badgers that were repeat visitors to feeding stations, treated cobs were fed on (as opposed to rejected) on a lower proportion of occasions (10–34%) than were untreated cobs (60%). At two sites, 450 m apart, feeding stations were established, each offering 12 corn cobs and water. Sites were pre-baited, to encourage attendance, and the experiment ran for five nights. Cobs were treated, in equal numbers, with 5%, 10%, 20% or 40% ziram in water or with water alone (as an untreated control). Treatments were assigned randomly across cobs.
