There pretty much all harmless.
Live in Australia and we have tones of huntsmans, dont even bother putting em outside, love em.
Even have em in the car sometimes, not usually on the inside - but its happened... - but when they run across the windscreen whilst driving you shit urself
Once my sister went to get in her car, put her hand on the handle, screamed, jerked it back turned out there was a huntsman under it!
