One benefit of doing all of it with just one sim is, I think, the other interactions beside bonding also raise the meter a bit. Either that or there is absolutely no decay on it, because once fully bonded I've never needed to have a sim use the bond interaction again to keep it topped off.
Also, they go dormant in Winter and are just always angry through the winter....no risk of a sting when you harvest the beeswax in winter though, because dormant bees do not sting. (No honey in winter though, just beeswax)
