 The drill plays an important role in the cultural tradition of bushmeat consumption, and is locally considered to be tasty, and in some regions, a delicacy.The commercialisation of hunting on Bioko Island has made this practice unsustainable.Hunting of the Bioko drill is banned in most areas of Bioko Island, as they predominantly inhabit protected areas on the island, however the ban is considered ineffective and hunting remains the largest threat to the drill's population.
