Not applicable (Human foot featuring hyperkeratosis/callus)

Global (found indoors and outdoors)

Omnivorous (referring to the human shown)

The image displays a physical condition known as hyperkeratosis, or cracked heels, often caused by dry skin, standing for long periods, or footwear issues. It is not an insect or biological pest.

Risks: In severe cases, deep cracks (fissures) in the heel can lead to bleeding, pain, and potentially infection if bacteria enter the wound. Benefits: Calluses themselves are the body's way of protecting skin from friction.
