I partnered with a company based out of Sweden to bring their hog attractant system to the U.S.
The name of the company is "Boar Collect", and they have developed a tree mounted liquid attractant dispenser that will emit tar, oil, or any liquid based attractant you fill it with. The unit functions just like the timer on your deer feeders, and can be set to emit the liquid whenever you choose.
I am working on importing the tar that they manufacture in Sweden, but there are tons of liquid attractants and tar/oil based attractants available here in the U.S.
If you're interested in this product shoot me a DM and I will gladly answer all your questions.
