On very hot fishing days, when nothing seems to be bitting, Ill get a very very tiny hook and roll up a little bread crumb on the end to catch small sunfish.
I beleive you can buy the same small hooks, and 'dip bait' at walmart, its basically to catch your own bait for larger fishing, its actually quite fun. But I am sure that itll work for this purpuse.
And I mean these hooks are really really small...I cant think of anything to compare it too.
