This was a Chilean rose hair tarantula which actually has a nice disposition, or should I say "not aggressive" and was recommended as a starter tarantula. He wasn't kicking his hairs up. It was a fluke and it's not a common, but from handling him the sixteen year old transferred microscopic hairs that got on his hands to his eyes when he touched his face. It's actually pretty serious for his eyes as the hairs will work their way through the eye layers.
It's not that the tarantula was being bad, they have no such notion, it was from not knowing something like this could happen. I gave my 6 year old a rose hair also, we don't handle it and I will be finding it a new home because of this. Tarantulas are interesting to watch when you feed them, but they don't enjoy being handled, only tolerate it. Also, their lack a memory prevents them from becoming "tame".
