This is gonna be a gross read - but it is worth it...
Tony makes and uses this to great success... just look at the photo album I have posted here to see how well it works... let me say this, also - all of Tony's photos come from 2 small 250 acre tracts... you do not have to have 5000 acres to make this work.
First - the gross part.. the recipe:
In a gallon container, combine 2 finely pureed apples (complete apple), a cup of plain non scented ammonia and fill the container the rest of the way with human urine.
I know.. but it works...
Place the loosely sealed container in a cool area and let it ferment for a week or so.
Voila! You now have the magic potion (mine is well fueled with Corona but I do not think it matters how you generate the urine!).
Ok, now find a likely area to put the fake scrape... cover edges are perfect.... and then find an overhanging (licking) branch about 3 - 5 feet over the ground...
If you have seen many scrapes in the wild, you begin to recognize immediately an area that would likely have scrapes just by the way the limb is positioned and the surrounding areas.
Rake out an oval depression about 2-3' in diameter under the branch. Use a stick of some other object that is devoid of human scent.
Pour some of the potion (I use about a pint) into the scrape but also save some to pour on the licking branch above the scrape.
I wear rubber boots and rubber gloves when making the scrapes and make sure not to touch any of the surrounding vegetation... do your work and then get out of the area.
You have now created a natural signpost that MAY attract the bucks in your area.
Tony has well documented bucks coming to his scrapes - he has some great photos!!
I have made about 12 of these so far and about 8 of them have been taken over by bucks in the area... I am going to assume I made the non productive ones in the wrong areas.
Here are some photos of one I made right behind my house (as a test, this land is not hunted) and it was immediately taken over by two bucks, I think... it looks to me like the scrape is being worked from two directions. I checked it this morning and there was clearly new raking marks and fresh urine in the scrape. The licking branch is well tortured also!
It sounds freaky and gross - but give it a try - you may well be surprised at the results!!!
