what i do is this- tap the jar so they fall to the bottom, get the lid off, tip it sideways OVER a small bucket-type container. i have calcium in the bottom of the bucket. not too much, maybe a tablespoon at most. when i get enough, i tap the ff jar and snap the lid on. i then take the bucket and swirl the ff in it. carry it up to my vivarium and hold it sideways while they all crawl out. i use my finger to scoot them out faster, and keep checking for any that might be stuck in the dust, and remove them as well. the bucket thingy is not very big, but it's WIDE, and they fall right in from the ff container. everyone does it differently, but this works for me, and no ff on the floor.
