Rarely. The only time I have, and the only time I have heard of anyone being bitten by Huntsmen is when handling firewood and they are under the bark or in cracks.How often do you have those spiders crawling on your body or face? And wouldn't a jolt in response to crawling legs cause them to bite? Like I imagine most people would slap their faces or bodies if they woke up feeling something on them
The instinctive reflex is to brush or flick rather than slap. It happened to me just now which reminded me of this thread. It was a Golden Orb spider, similar to the one in front of the tattooed arm above but nowhere near that size. I was sitting in the sun reading and felt something large crawl onto my elbow. I just brushed it off and it curled into a ball on the ground. They are not harmful.
Another funny thing that happened since I last posted here, I walked into my kitchen one night and saw a large black spider that I couldn't identify in the middle of the floor. I didn't like the look of it so I stepped on it with my boot, and it EXPLODED into thousands, literally thousands of tiny spiders, swarming in every direction over the whole floor. It must have been a female carrying a sackful of young. There was a can of insect spray within arm's reach so I quickly sprayed as many as I could before they could disappear into and under the cupboards.
