I just found this product and wanted to share with others. I am going to try this stuff this year for sure. Beaver castor and sow in heat is on the way for my spring hunt.

Hope it works for you. Here in Montana it is spot and stalk only for bear. No bait or scent lures allowed.

Most pheromone based scents are mainly urine. The pheromone molecules themselves have a very short half life, as in days. But just in case, don't put the sow in heat on your self... lol.

Some of it is food scents..... which would be great for trapping certain critters. Coons love the sweet stuff.
