Another trick is to have a water dish or pool that is craggy or tiered. Crickets that jump into my water dishes now usually skim themselves across the top an to the edge, or water step that is above water, because it's a rough edge they can grab a foot hold and get out.
Crickets I've noticed only really drown in flat edged bowls where they can't get a grip on the side of the bowl to get out.
