As mentioned in the link...

Deer encounter all sorts of odors in the woods. They come across cattle urine, hog urine, coyote urine, etc. If they happen into human urine, I seriously doubt that they will, or can, associate the smell with humans. The fact that some hunters make mock scrapes with their own pee would help back up this theory.

Speaking of human bodily waste in the woods, did you know that coyotes will eat the "other" human waste?

I really can't type well enough to totally express my opinion here. But, I'll give you the jest of it.....

For years, I wouldn't pee anywhere near a stand and always carried a bottle to and from the stand. I was meticulous about what I did. Some would, say anal. However, a couple of years ago, I read an article written by some biologist working on a big Sth. TX ranch. Basically, they made a bunch of mock scrapes. Some with deer urine, some with human urine. Then they monitored them with trail cams along with the same number of known live deer scrapes. What they found is this: All of the scrapes were used by deer. None, noticeably more than the other. And seldom do particular deer revisit particular scrapes. In fact, there was a higher incidence of re-visits on the human pee mock scrapes. Of course this data flies in the face off everything we've ever been taught. But, this was a study conducted in a very scientific manner. I gotta believe there is some merit to it.

Basically, what I concluded from it was: Scrapes are to deer, as fire hydrants are to dogs. If they are there, they are gonna pee on them. But, they are not going to go seek out the specific hydrant they peed on yesterday.

Since I read this, I have started just peeing wherever I got the urge. Haven't noticed any difference and killed the biggest buck of my career last year. Go figure.

I have hunted areas for quail, before and after deer season. We peed just where ever and alot of times take a break to water the dogs, we'd fire up cigarettes and have a smoke then go out and run into all kinds of deer and some really nice bucks. I've drank coffee in my deer stand and there's been times I've had gas on my hands from my 4-wheeler and still have gotten deer. Now coyotes and cats are a totally different story.

Mock Scrapes and Deer Scents

Here's an article written by Shannon Thompkins of the Houston Chronicle that includes references to the study I spoke of done by Ben Koerth:
Scrapes can tell some surprising tales
Copyright 2002 Houston Chronicle
The smell hit us before we saw the bare patch of sandy loam raked under the
holly tree.

Thick and musky and a lot like fresh-turned wet soil, the scent once
experienced is unmistakable.


Leaves and other debris had been cleared from a spot about the size of a
trash can lid, leaving a blank canvas of dirt on which was written messages
my brother Les and I could only guess at understanding.

What we knew for certain was that this was a deer signpost.

Heart-shaped prints of deer hooves were pressed in the dirt, some of them
obviously made as the deer pawed the ground.

Some of the grayish sand was stained dark and wet. That's where the smell
came from.

A holly limb hung about 3 feet over the bare spot. One of the twigs on the
end of the limb was broken, its dead leaves a stark brown against the waxy
green dominating the tree.

Here was a perfectly classic deer scrape, and a "hot" one at that.

Deer hunters thrill at the discovery of scrapes -- these pawed spots on the
ground, almost always situated under an overhanging branch. They most often
are located along edge -- the margins of fields or pastures, openings in
thick brush or along logging roads or trails.

Finding one of these deer-made spots carries so much more impact than simply
finding random hoof prints or even tracks around a feeder.

A scrape is a physical proof that deer -- bucks, in particular -- are in the
area. Scrapes are important discoveries -- no doubt about it. But they may
not be the ***** in a buck's armor many hunters believe them to be, nor may
they tell the tales hunters think they do.

Generations of deer hunters have been taught that scrapes are made by bucks
looking for does during the breeding season -- the rut.

A rut-addled buck makes a series of scrapes -- paws bare a piece of earth,
leaves his testosterone-charged scent on the ground by urinating over his
metatarsal glands and on an overhanging branch by rubbing it with his
preorbital glands -- to mark his territory and leave a kind of "trapline" by
which he attracts willing does.

Find a scrape, sit over it long enough, and the buck, which makes regular
rounds of his scrapes, sooner or later will be back to check it. And that
puts him right in the sights of the hunter.

Except that almost never happens, if it happens at all.

Over the past few years, new research into scrapes -- including "real"
deer-made scrapes and human-made "mock" scrapes created with commercial deer
scents -- have shown that much of what hunters think they know about
scrapes, the use of deer scents and related issues "ain't necessarily so."

Using the relatively new technology of remote-sensing cameras, it is
possible to monitor natural scrapes around the clock for weeks or even

The results of researchers and average hunters using these
infrared-triggered cameras to monitor scrapes have shattered some of the
long-held beliefs about what these marked areas mean and how deer relate to

Scrapes are not the purview of a single buck, nor do bucks (or does) make
regular visits to the sites. They are, as deer researcher Ben Koerth said,
"community property."

Koerth, a research associate at the Arthur Temple College of Forestry at
Stephen F. Austin State University in Nacogdoches, offered insight into his
remote-sensing camera studies of real and fake deer scrapes at a seminar on
using the cameras for wildlife research earlier this year in Kerrville.

Much of what Koerth and others have discovered flies in the face of what
hunters figured were immutable truths.

While a single buck may create a scrape, typically pawing it out in the
"pre-rut" a couple of weeks or more before the start of the actual breeding
season, other deer make it their own.

"If a deer -- any deer -- passes by (the scrape), it will use it," Koerth
said. Does as well as bucks will stop at a scrape and leave their scent,
then wander on their way.

The huge majority of those visits occur at night, Koerth said. And just
because a particular buck visits a scrape, it doesn't mean he'll visit it
again on any regular schedule. He may never visit it again. Over long-term
monitoring of scrapes, Koerth has found no regularity or predictability to a
buck visiting a scrape.

"They may visit it once and never come back," he said. "We did have one buck
come back to the same scrape, but it was five days later."

Scrapes -- both natural and mock -- attract more bucks than does. This jibes
with personal observation via remote-sensing cameras. Remote-sensing cameras
set to monitor scrapes on our East Texas deer lease recorded what appeared
to be completely random visits to scrapes.

The huge majority of the visits were by bucks, and they came at night. But
during October and the first week of November, a few visits came during
daylight -- mostly right at dawn or dusk, but a couple during the middle of
the day.

By mid-November, less than two weeks into deer season, more than 90 percent
of the scrape visits were at night. Several bucks visited the scrapes, but
only one made a return visit over the more than three months the camera
monitored the scrape.

From that information, hunters can infer that setting a stand overlooking a
scrape is no guarantee that a buck will visit it on regular basis.

Deer are attracted to scrapes by both sight and smell, Koerth said. He has
proved this by making mock scrapes but using no deer scent on the spot and
recording several visits by deer.

Mock scrapes do attract deer, he said, particularly when made in a spot deer
would naturally use for such a signpost and when combinations of buck and
doe scents are used.

Koerth's studies also cast serious doubt on one of the strongest held
beliefs of deer hunters -- that the smell of human urine inevitably spooks
deer into the next county.

When doing the mock scrape study, he used human urine as the only scent
placed in some of the mock scrapes. His cameras recorded bucks using these
mock scrapes, leaving their own calling card on the bare earth. And the
research showed that buck visits to mock scrapes dosed with human urine were
"not statistically different" from those on which he used buck deer urine.

Amazingly, the mock scrapes dosed with human urine drew statistically more
deer than the mock scrapes baited with doe deer scent, Koerth said.

"There is no indication that human urine scared deer at all," he said.

If nothing else, this is great news for deer hunters who like to take a
Thermos of coffee to the stand.

I had read something a while back about a guide that would pee near the feeders whenever he came by to refill or check them. His philosophy was getting the deer to associate human urine smell with the food from the feeder. Not too sure how scientific his approach is, but he said that his hunters didnt get busted as often as they did before he started doing that.
We still try to keep as much of our scent out of the area as possible and use the wind to our advantage.

Makes sense,, I've never worried about it. If any of you bird hunt think about how many time your male pup would come over and smell it then mark the same spot to show his dominance. It a male thing with animals. you mark a spot, the next one in marks it a little bigger/stronger. It's a territorial thing with all living things.

One morning, my breakfast went right through me (more like RAN through me) and I had to go. CLimbed down the stand and took a big 'ole crapper right behind my stand. The kind that would peel the paint off your stand and give you a permanent orange afro.

Saw a nice 8 pt during that afternoon hunt. I don't think it affects the deer.

Although that 8 pt was sniffing the air and started to wobble a little. LOL!!!!!!!!

How does human urine affect deer? This has been a lifelong debate amongst deer hunters. And as I stated above, my opinions have changed in recent years.

So, I tried to put our little discussion to the test.

Friday before deer season, I made a mock scrape. Just cleared the ground with an old shredder blade and ****'d in it. I did this near my stand so I could see how the deer reacted. Everytime I go by it, I **** in it again. I did the same ting Saturday afternoon before the hunt and Sunday morning after the hunt. The results are, I saw 5 different bucks work that scrape in 2 hunts.

You guys ought to try it around your stand. I don't necessarily think it attracts them. But, it's fun to watch them react to you.

Here's the photographic proof:

It seemed like I used to never kill a deer unless I peed while there. Now I have been serious about not around stands and feeders and we still kill deer but no kidding it used to never fail....I'd get down thinking I won't ever see anything now and then ten minutes after climbing back up the ladder a buck would be heading for me....probably coincidence but fun to think about.

Been there myself. I had the coffee go thru me a little quicker than expected on morning in the stand before dark. Thought I could hold out till after the hunt. Wrong, just starting to get grey outside and I bail out of the stand and scamper into the brush thinking I was a good 50 yards away. Well as light continued to arrive I realized I was only about 10 yards from the stand. Oops. Saw no deer that morning but I did get a colon cleansing.

Urine or Bathroom Breaks

I have had it go both ways. Some hunts where I pee for hours and then later on a buck or doe comes right under my stand.

Then other times I pee once and a buck or doe comes within 60 yards and they snort and run because of the smell.
