Its bite is painful and can be fatal in rare cases. Epidemics of bites have been reported, and Ukrainian farm workers have been bitten in the fields. In Kazakhstan, where it is called karakurt, it has been reported to bite and kill camels. Only the female's bite is dangerous to people and cattle, because the male cannot get through the thick outer skin.1
