Beaver castor?

I had a guy give me a pint jar full of liquid castor this afternoon. Well he traded it to me for 5 beaver carcasses he wanted to make bait with. My question is how do I get my best results and longevity out of it. I've only used commercial baits and fresh castor before. I've never seen it as a liquid. It sure smells good.

Don,t use too much, a little dab will do you.

Thanks Mr. Kirk! I took all the good advice you gave me the other day and set 10 traps on a farm pond that had given me fits this past spring. Caught 5 out of it in 4 nights. Happy landowner and happy me!!!!
