Are essential oils dangerous for snakes?

[mlededee]

I'd need to do some more research as my practice doesn't deal with herps very often but it is possible, just because of the global locations of the plants, that tea tree and eucalyptus may be safe for some reptiles in such diluted quantity as they would encounter in the wild IE brushing up against the leaves of the eucalyptus tree they are climbing, etc.

Those oils are not safe for reptiles, not even when diluted. They are among the most toxic to reptiles, in fact. Brushing up against the leaf of a whole plant is not the same as coming into contact with a highly concentrated essential oil that may have been processed in a number of ways (making it into a form which would not be found in nature).
