Hey Flint -
Thanks for the tips, super informative !
Question: do you believe there to be any difference if the Kreso-D is applied to dead or dying trees as opposed to living?
In your experience in seasoning rubs have you tried it on various tree conditions or types and observed any preference by the hogs?
The only thing I've noticed is that hogs seem to use trees with rough/deep bark longer than ones that are smoother. (I.E. pine tree bark degrades rapidly, hardwoods not as much). Also, telephone poles and fence posts (which start out smooth), will be abandoned much quicker.
It is the pungent smell and parasite repelling action they are after, BUT a rough surface helps them to 'scratch' and also aids in removing old hair and caked on mud that traps parasites. So the reason for them 'rubbing' is two fold.
I have tried placing rubbing posts (treated) at the bait sites where I hunt them, but it doesn't seem to 'attract' them. They will use it (some) as a matter of convenience.
The most 'action' I get with the product is when I treat a line of trees (several trees in a row) along a path or in an area where pigs travel. Not unlike a 'rub line' a Buck Deer would make.
I DO try to establish that set up in the area I hunt, but the idea is simply to make the 'area' as inviting to them as possible (food, rub trees, nearby cover, not over hunted) and NOT create a singular method to 'attract' hogs. Hogs 'are where they are' for a reason...and that's not usually to scratch on a tree.
IMO it is a useful product to put in your toolbox, but don't expect it (alone) to bring pigs to you.
Where I live...the landscape is heavily wooded, so the application is both easy and well used by the pigs. But some folks hunt hogs where there a few if any trees. I have not experimented with it, but I suspect you could still get results by saturating certain soils with it. Creating a 'dry wallow' for them to dust in.
That's all I can offer. Get some, experiment with it and see if it works in YOUR setting.
