Possum you by chance didnt put that in a pipe and take a puff did you? LOL I have known a few over the years that have.I hear from old indian folk lore that castor is to have a hallucinatory effect.Known by some to be called "Castor BUZZ".

Possum, That is interesting. My tests with dry versus green have been the other way around. I have had better results with beaver using green castor in formulation. Makes sense to me since beaver mark their territory with fresh castor, not dried. I have on the other hand found dry castor to be much more effective in canine and cat formulas than green. I took lure formulating instructions from Gary Jepson (creator and former owner of Fur Country Lures) several years ago and he stated having the same results.

always wondered what them ole indians had in that Pipe. Ive noticed the same thing Skinner always diff every clanl Always wondered if the quality a water they were in had any effect on there castor smell.

Biologists say that castor odor is directly related to diet and time of year. In the north beaver feed on their food cache most of the winter and more green vegitation in summer thus the varying odors from season to season. Around here beaver feeding on corn in the fall will have a different castor odor than beaver feeding on primarily tree cambium.

wow this has turned into a very informative post! archive material maby?

Most things change odor when dried,rehydrated and in this case diet as I stated before influences odor as does time of year when harvested.Each beaver has his own scent therefore knows when another has marked his area. It may all smell like plain old castor but the difference in there and they know it.

I have seen castor mounds 3 ft tall in Arkansas from repeated applications from different beaver over a period of time. Granted these were found along a river that has a constant flow of beaver and a good population base.

used that lure to catch a 35 pounder on thrusday,put a glob of castor on the mound and dripped some of the castor-soaked glycerin down the bank into the water,next day bang there it is at the end of teh drowner
