Introducing the E-Thermal Scent Pads from Wyndscent. E-Thermal pads are designed to be used either by hanging on branches, placing on the ground, or placing in heating devices. Designed specifically for the E-Thermal Enticer as well as other heating devices. When used with a heating device, each pad will last up to 3 hours of continuous scent dispersal. Heating the scent makes it smell stronger and fresher and is the most effective way to disperse scent in both warm and cold conditions. Another great thing about E-Thermal Scent Pads is they are 100% biodegradable and are a very eco-friendly way to disperse scent in the woods. Apple is a great cover and attractant scent. Deer are often attractant to the smell of food, especially apples.
