Well, I used to. Mostly because even I am repulsed by it, and I don't want to touch them but also, many of the crickets that drown float into ridges between rocks or by the log, making them hard to spot. Even worse are the ones that I can't get at, I usually have to wait until nighttime when my frogs are out of their cave to get them. And the ones that are sucked below the filter, but are too big to be sucked into it can elude me for a handful of days, too. It's irritating. However, I've begun doing longer and closer examinations for drowned crickets, and I've not had a moldy one in a while now due to my new constant schedule of checking for them. Also, I've changed the spots where I place the crickets, so less and less are drowning now.
