I have a question about the shelf life of Code Blue Scents or scents in general. I picked up a few scents last year and used them sparingly. Do these scents spoil, or loose effectiveness after a certain period of time? If so, does a bottle of scent bought last year that hasn't been opened retain its effectiveness? I want to avoid putting out an estrous scent in a few weeks that has gone bad and ruin a hunt. Is there any documentation out that addresses this issue?? Thanks!!!
