When the rut is nearing, estrus urine—also called doe-in-heat urine—is just the ticket to bring bucks your way. Estrus urines provide the scent a buck is looking for as he cruises his home area during the rut. A buck that encounters the scent of a hot doe is almost always going to follow the trail to investigate. Used by pouring on the ground near your tree stand or on a drag rag when walking to your area, estrus urine will definitely catch a buck's attention. Some hunters have great success with a double drag, dragging one rag with estrus urine and another with buck urine to give the impression another buck is following the doe. Estrus urine can be purchased in many of the forms discussed above and also some others, including liquid, gel, spray, aerosol, fogger and even foam.
