Dusting fruit flies can be quite difficult because they are so small. I try not to get any dust in the tank, but sometimes it happens. When I dumped the fruit flies in today, one of my toadlets was eagerly awaiting dinner time and I accidentally got a bit of calcium powder on his head. I prefer not to handle toadlets as they are so small and fragile. Will he be okay, or should I try to rinse him off?
