Here is a tip that was passed along to me - and I have not tried it yet - but it looks (and smells) like it will work fine! The gentleman that gave it to me regards it as his secret weapon and he is a VERY successful hunter.
Get a fresh tarsal gland off of a decent buck - I think the ranker, the better. Taking them off of bucks that are hot in the rut seem to be the best because that is when the glands are the darkest and have the most "male buck" scent...
Take that gland and put it in a good, thick sealable baggie. Add about 4-5 ounces of hot water (not boiling, you do not want it to cook the skin) and then knead the bag slowly and gently, using firm pressure.
What you want to do is to get that rank scent to transfer out into the water.
I made some today and used distilled water just to try to make it as pure and scent free from contaminants as possible - although I am not sure that did much good - this stuff is POTENT!
After you have created the mix, transfer it into a good, clean scent free storage container - I used a larger, glass pill bottle today.
I can not vouch for storage time, I am going to make the stuff as I need it - and use it right away... I do not know if it will "go bad" or not. I only made one batch and am going to use it this week. I am going to store in a cool area but not refigerate.
My buddy makes it as he needs it... and then tears a small hole in the corner of the baggie and dispenses it right on the spot.
Now... one big problem may be getting one of those big bucks to hold still while you whittle away on his back legs (everyone of the critters I asked refused)... so... I went to the local processor on a Saturday late in October and there were about 7-8 bucks there waiting to be processed. I asked for and received permission to remove the glands and got 5-6 of the best ones... off of the biggest bucks that were there.
This looks like a great scent to use in fake scrapes, to use as a cover scent on your boots or to create a scent line in the breeze with while hunting...
Give it a try and see if it works for you!
