I hate those suckers! We had them by the tons too until we finally had an exterminator come spray, thought that's not really an option for you with the torts. The exterminator told us they reproduce faster than black widows and I believe him because we were seeing them more and more no matter how many we tried to kill. I hate risking trying to kill a spider and it getting away so I usually use hairspray. Spray them stiff and then clean them up later.
