Rhodium
Vanilla
Anise
Poplar Bud
Birch
Wintergreen
Sweet Flag
Skunk Essence
Honey
Cinnamon

Ideas?

When using any of the mints a little goes a long way.

Ive used honey and like it. Nice and sticky, I mix about one part honey to three parts Castor

I make poplar bud oil myself and have used it mixed with castor and straight. If you have muskrat in you waters your sets will be gagged with them if set shallow. But good additive for deeper hind leg catches

The others I haven't used

Thanks Turtledale for replying. I'm gonna soak some castor in burgundy wine.

One thing I always consider when mixing any essential oil with castor is what nontargets will it catch. I’d muskrats are a welcome catch the sweeter type oils work well. Oils that may attract otter are another thing to consider. There are also some combinations that work better for predators.

Saw some cheap blackberry/vanilla wine in Piggly Wiggly yesterday. May go back and buy that for the 1st "official" castor test soaking.

I've used perfume/after shave with some success in a castor based lure. Some of the smells made for people have a lot of research, money and time put into them.

Swamp and others, I have used cinnamon and tried Allspice in a some homemade castor lures. Produced well but I really couldn't see a big difference in my catches.
AND like Todd and Turtledale mentioned, a little goes a long way as on a least one test batch I used TOO MUCH Allspice and my nose could barely detect castor odors.
I think I'll let the lure makers make my lures....lol

I soaked castor in wine last and had good luck with it ,but I had great luck with just the leftover wine for coon, mink, and muskrat , every time I used it I had visits . made 2 more quarts for this year.

I like cherry oil.

It’s loud and carries really well.



Plus, add two other ingredients and it smells like borkum riff cherry cavendish which is one of the greatest smells ever.

I like to add a bit of watermelon to my beaver lure.
It seems to attract the black beaver.

Went back and checked my notes, Calvin Cobb out of Homedale, Id. gave me beaver lure recipe from the Mountain Man day. It included a spice called Mace.
The closest smell I could find was Allspice...add that to Swamp Wolfs list.
