Sac is used by the beaver to waterproof their fur. So it's the body smell of the beaver and it also makes a great addition to lure and bait for predators for the same reasons.. Most lure makers will buy or trade , but it doesn't have the value of castor. I make my own castor lure with oil and without. Both work very well, in fact the oil mix works a few percentage points better.. Your welcome.

Happy birthday Beav.

I was taught by an old timer, to cut up dried castor real fine, and reconstitute it in sac oil, soaking it up until the castor swells back to wet castor volume. This can take a year, so make it in advance and add oil as needed.

I have caught a few thousand beaver doing this.

I cant compare the catch results of using anything else in competition with my own lure because I never have done it. I cant hardly keep up skinning the way it is.

I knew an old beaver trapper named Jim White that lived in WY. Had been a tail gunner on bombers in WWII and survived. Told me he caught three thousand dollars worth of beaver after he got home his first season after the war. Lot of money in those days. Took his money and went to a brothel in Laramie. Got to playing poker there. Was broke in 3 days. Told me he thought they had cheated. I really liked that old man. Last few years of his life he only had a few sets out but he always had some. Sewed his plews up on the steel rims of old wagon wheels to stretch them. Clean skinned them rather than fleshing on a beam. Set for a front foot with longsprings and used oil at every set.

Apparently that's another one of those myths the oldtimers threw out to get younger trappers off course. Kind of like scent control, or foxs fleeing the county upon smelling yote pee

A lot of advice is just theories never really put to the test. The animals wont lie so always check it with them. After you really start testing stuff you start seeing who really knows there stuff. Muskrat and mink glands are unnatural in a dirt hole in the Flinthills of Kansas but they will catch a yote or two.

I guess I could never get my head wrapped around drying castor and then gridding It. Seems like a lot of extra work when you can just scrape out the green contents and add glycerin to make a lure. Castor straight from the sac Is as natural as It gets.

Glycerine is what's not natural. Both the sac oil and the castor are. I believe my lure composition with the sac oil reconstituting the dried castor , is stronger and more potent overall than green castor with it's percentage of moisture plus the glycerin.

You only live once Beav. You don't want to complete your entire life without trying the most popular old time lure, and also probably the best kept secret on the planet. I didn't come up with this, it's older than at least 2 of you and me put together. That recipe is older than dirt.

x2

There are lots of lure ingredients that aren't NATURAL when mixed and they seem to work just fine.
I'll stand by my beaver lure It seems to do the job just fine.

Me too Beav, but, I've tried a little of everything.

I've been after those flat tails for about 60years and I have tried a lot of things, home made concoctions and over the counter concoctions and all of them worked to a point. But I settled on what I have used with great success.
Probably the best beaver lure Is to milk that fresh caught beaver right at the set.

Cant say that if you haven't tried everything Beav and by your own admission you haven't tried sac oil and castor together. Lol. Just messing with you some Beav. A little disclaimer here, I've never caught a beaver in my life.

Beav, I know you are going to go right to the end and not give castor and sac oil together a chance, lol.

Notice the reverse psychology there.

I was adding sac oil to castor before you were out of huggies. lol But after trying It I decided It wasn't making my lure any more effective.. Also sac oil has a tendency to spoil If not kept frozen.

I see there are several lure gurus that add Glycerin to their lures and urine. So I can't see where It' s going to spoil the pot.

I don't think sac oil spoils or taints. I believe it keeps near indefinitely , in my experience. I've had jars of it for years, and you'll get some clear oil on top after a while .

Well I can guarantee you that if you leave a oil sac laying around It will taint. One of the best coyote attractors going.

Yes the sac will taint. The oil, if removed from the sac, and is not contaminated with blood, will not taint.

So true because that is how my sac oil is for all that I save. I have more now that I need to drain. then grind up the sacs them. I just grind up today my coyote anal glands and will do the beaver oil sacs tomorrow .

so coydog2 please explain how you can possibly dry down an oily old oil sac so It's dry enough to GRIND.
