You're doing fine...a multi-method approach is often the best, since you want to remove as many as possible safely, while you wait for additional product that's more
lethal to mites. It's very common that mites seek relief in their water bowl & that was my first guess, but I'm sorry that turned out to be correct. Just do a good job on
getting rid of them though, so hopefully you won't have to re-treat (as some have had to).
