Doe-N-Estrus Gel: is collected from individual Doe as they show signs of being in estrus and then converted into a Gel. Doe-N-Estrus Gel urine has been known to be the most productive during the Rut but has been proven to be just as effective during the Pre Rut and Post Rut periods as well. Not all whitetails go in their estrus cycles at the same time and if a Doe is not bread it could go into another Estrus Cycle up to 28 days later during the Post Rut period .One method is to apply to several scrapes in or around the selected hunting area and apply on branches at least three feet off the ground to really put the scent in the air so that any buck that smells this down wind will be forced to investigate and come in seeking out this hot doe.
