I am always scared of injuring the spider with the slide method. I have hit upon a method which is much simpler, and rather satisfying to execute. Wait until the spider is stationary. Put the glass on its side with the mouth directly in front of the spider. Then - tickle the spider's behind. Invariably the spider will panic-run forward, right into the glass. Lift the glass and there you have it! Spiders can't climb the smooth sides so no lid necessary. I have found that persuading the spider to enter the glass without tickling its behind to be much more challenging for some reason. They sense the trap, or at least that it's a sterile dead end. But startle them, and they'll always run forward in a straight line.
