RE: SCENT DRIPPERS ?
I have always found the " drip bag" to be iffy. But I cannot say they scare deer away. Therefore, no harm, no foul.
I strictly use mine on mock scrapes during pre-rut and rut. I have had bucks come in and tear the hell out of the scrape, and I have seen evidence of does in heat urinating in the mock scrape.
However, beware! On more than one occassion, I have had bucks bed down nearby. It is my opinion, that it is possible that the bedded buck thought another buck was in his territory, and he bedded down nearby to watch for the invader to arrive at the scrape. Guess whom the buck sees?
