Human hair has been used for centuries to repel animals and control pests in various ways. It works differently on different species. For moles, the hair is irritating enough to drive them away. Deer, on the other hand, are alarmed by the scent of humans. In India, rhinoceros beetles can be trapped using a simple ball of human hair. Farmers place the hair strategically on trees, and the beetles, trying to walk over it to reach the crop, get their spiky legs tangled, rendering them immobile. Another strategy involves using human hair to encircle a garden to repel rabbits. While wild rabbits will be scared off by the scent of humans, suburban rabbits, already accustomed to it, will adapt.
