The Interdigital Gland is a sebaceous skin gland located between the toes on all four feet of a whitetail deer. An opening between the toes leads to a skin like pouch that fills with a yellow, brown waxy substance called sebum. These compounds left behind in a deer’s trail evaporate at different rates as time passes. It is believed this change in odor allows a deer to trail another in the correct direction. Add two cups of our sex specific dominant buck interdigital gland to a gallon of your buck urines for authentic, natural scent trailing communication.
