- My friend had a whitetail bite which was mild but a year after he had an acupuncture treatment and the bite wound reapeared. If the whitetail has been proven to not have a necrotic venom then I suggest it may be a bacteria other than the venom that causes the adverse reaction, after all they prey on other venomous spiders so maybe it's carrying a bacteria from another species it recently devoured. I have seen whitetails approach the funnel webs of black house spiders, tap the extremeties of the web causing the house spider to emerge seeking prey and then the whitetail pounces.They are very evolved for spider hunting. However I have also seen that they are not the top predator in my house. I have seen a daddy longlegs carefully wrap up the legs of a large whitetail that was moving across the ceiling. The whitetail was oblivious to the slow gentle entrapment. Once the whitetails legs were bound only then did the daddy longlegs bite it, the whitetail unable to move. Since then we refuse to kill daddy longlegs as they are excellent spider controllers! Leave them alone and they will help you out!
