All of the southeast produces the castor I want. It tends to smell the same from East Texas to the coast of Virgina. Good stuff!

Big difference between castor odors from east to west. I've smelled several lures made from eastern castor, and they don't even smell like castor to me. More like something that came out of the spice cabinet! Not sure if the beaver care or not, but I prefer to use castor that smells like that of the area I'm trapping. So for western beaver I'll use western castor, if I was to go back east to trap them, I'd want to use eastern castor.

I know several lure makers (the boss is one) only want castor from one area or the other.

Paul's Backbreaker works good on beaver in my area. I'm about as west as you can get for beaver in mainland N.A.
