did the does estrus work?
I went all-out with this code blue stuff. I set up my blind in a likely spot two weeks ahead of time.
On the day before shotgun season opened I went out & made some mock scrapes & put a few drops of estrus in each, and also put some drops of doe estrus on a rock wall . I hung the Code Blue 'drop time dispenser' that sprays out a small plume of pee at 20-minute increments from a well-placed pine. I also hung a few pieces of cotton gun cleaning patches (using tie-wraps) from branches around the perimeter of my spot, with a couple drops of estrus on each. I pretty much used up the whole 1oz bottle. So if a deer DIDN'T smell this stuff, its nose must've been broken.
Results? A buck 'shat' on the spot on the rock wall before I even came back Monday, and he sniffed and wheezed at me as I was walking in that morning, and again on my way OUT Tuesday after sunset. So the urine definitely attracted (kept) deer in the area.
Also, Tuesday afternoon while I was sitting in my Doghouse blind, a woman and her dog (both wearing blaze orange) came walking through the area, and the dog rolled around on my scrape. She's talking to her dog "Now what are you getting into? What are you rolling in?" when she hears my whipsered voice coming out of nowhere:
"Deer Pee! Your dog is rolling in deer urine!"
She quickly figured out where my voice was coming from, and she & the dog moved on quickly... I thought it was pretty funny, and the whole episode broke up my boredom. (I was reading a book a lot of my time otherwise...)
I ended up shooting my deer while still-hunting less than a hundred yards away, on my way in to my spot after sunrise on the fifth morning.
I knew from previous scouting trips and from getting sniffed at Monday morning and Tuesday night that there WAS a decent-size deer in the area. I'd like to think it was my "expert doe estrus application skills" that kept him there so I could get a shot on him.
That, and peeing underneath every treestand I saw... (j/k)
YMMV
