Buck Fever Pre/Post Rut Scent is a year round synthetic scent used to scent mark trails, scrapes, and vegetation. Regular use will encourage bucks and does to over-mark with their urine/feces. It is recommended to begin using in summer to attract deer for early season and also effective for first time set ups and scent trails. This scent encourages deer to socialize and re-mark their territories often because it makes deer think that other deer have been in the area.
