I have seen this once. About 5 yrs ago, had a buddy who is an excellent bowhunter talk me into getting some Evercalm. He knew I wasn't a fan of using any types of scents, but he insisted, told me that deer had bedded down where he used it.
So I got some, put it on some branches. very first time, sure enough, I had a doe and fawn bed down near the scent. I used some the next couple seasons, had deer and hogs both bed down in shooting lanes, which were not bedding areas.
I made a mock scrape, I put a small amount of evercalm on a branch right above the licking branch to test what would happen. That evening, a basket rack 8 point came into the scrape, worked the licking branch, pawed it, peed in it, walked away all sprung up, high stepping, then came right back and laid down right on the scrape, and had me pinned down till after dark. Never saw another buck at that scrape, expect for some nighttime pics. It didn't work everytime, but I had enough pics and sightings to know it had some effect for sure.
Tried the same routine one other time with a mock scrap, with no success. They also had some doe in esterous stuff, and it was really expensive. Bought some of it, used it with no success that I could tell.
Like I said, I'm still not a foreign scent guy at all, and I'm not advertising the stuff. I haven't even used any the last couple of years cause of the hogs bedding down.
