congrats on the new addition.
As far as the venom compared to bee stings goes, people just use it as a comparison as to how the bite feels- ie a person with no bee allergy gets stung vs being bitten by a rosie. chemically, they are entirely different. There is not one single documented case of a person being allergic to T venom.
That said, they are perfectly happy being hands-off animals. Out of my eight Ts, my rosie is the only one that ever gets handled, and that is only when I bring her out to show to kids.
