Where are there documented Blacktails with CWD? If it is truly Blacktail estrus, I don't think there are any problems.
I've been seeing bucks following does nose up, so I'd use it now.
I don’t believe there has been any documented cases, but beginning Jan. 1, 2020, the state of Oregon will be banning the use of elk and deer estrus scents due to the possibility or threat of it occurring. I’m sure other states like Washington will follow right along in the not so distant future.
For the OP, I would definitely be using them right now! It’s that time!
