Hello, Depending which virdis subpecies you get bit by the the venom varies. some are more myo toxic than others and some have neurotoxic components to their venom. helleri has a very potent venom that makes crofab not to effective at all. oreganus has a myotoxic venom lacking most of the neurotoxins found in its southern cousin.
I have been bit by a mount lemmon black and a prarie,and a helleri. the black lacked all n-toxins the virdis virdis had both components. the typical virdis would hAVE TO UNLOAD ALL OF ITS VENOM TO KILL YOU. BUT BE CAREFULL THER MYOTOXIC PROPERTIES ARE BAD ON TISSUE. ie>> OREGANUS IS MYOTOXIC. HAVE FUN. BILL
