RE: Should I refridgerate buck/doe urine after opening?
Was it a commercial product or from a kill ?
Newly purchased or thawed from last year ?
Was it previously frozen ?
Mixed plain/estrous urine or single doe ?
I keep mine in the fridge during the season , and I don't usually have leftovers , but any remaining lure of any animal type will get frozen for later use . Unopened commercial products when frozen can last over a year in the freezer , but will decline slightly . Freshly harvested urine can stay frozen for two or better . The product can easily be tested by removing a shaving and thawing it out . Plain urine will attract curious deer of either sex throughout the year , and makes for great practice during the off season . Take a camera instead of a bow or gun and practice drawing deer to you . Just as challenging as real hunting , requires the same skills and gear , and you'll never have the "one that got away" .
