This spider is non-aggressive, preferring to disappear into a rock crevice if disturbed.
The following is a report by Deb Hunter, a very experienced caver, after receiving a bite, suspected to be from a cave spider as cave spiders were in the vicinity of the location where she was bitten.
"About 30 seconds after turning and leaving the cave entrance a numbness spread from near the base of the third finger of the left hand. A red spot was centred at this site. The numbness affected an area including adjacent knuckles and the first section of that finger. A few minutes later, pain began, centred at the site. It was accompanied by redness and swelling. This pain intensified until it reached a peak at about 12 hours, then gradually abated completely over 3 days, accompanied by itching as it subsided. Swelling continued for a few days after the pain subsided. The thing that stood out for me was the numbness: I described it at the time as a feeling of a local anaesthetic spreading quickly."
