Deer have a number of things that they generally dislike or avoid. One of the biggest things that deer hate is the scent of humans. They are naturally wary of humans and can be easily spooked by the presence of human scent. Additionally, deer are often repelled by strong, pungent odors, such as those produced by certain plants or by products that contain urine or other scents from predatory animals like coyotes and wolves. As prey animals, deer are always on the lookout for potential danger, so anything that signals a potential threat may cause them to avoid an area. By understanding what deer dislike, it is possible to take steps to minimize their impact on gardens, crops, and other areas where deer may be unwanted.
