Hulmîkak

Hulmíkak is the venom of the hulmiis  ant, a  large (1/2")  black carpenter  ant native to  temperate forests.    To  most  arthropods  and  other invertebrates,  hulmíkak  is  a  lethal  nerve  poison,  but  in vertebrates, it  attacks the  optic nerves, causing blindness; at minimum, it impairs vision.
