dude those are white flies

you can try my beer trick, but its already too late. you have eggs under your leafs. you can get rid of them by..

taking your finger, dip it in water and run it across the bottom of the leaf, takes the eggs right off. get some sticky fly traps.
also any leafs that are totally infested i'd just pluck them off, its really the only way to get rid of them.

after you do that, take you plant outside and blow on it, canned air works good. this will get rid of the ones flying around, shake the plant. inspect it then bring it back inside.

chances are that you have some flowers (hibiscus is the worst) near your house, bushes ,,shrubs,, ect that is breeding white flies, get rid of those too, or use pesticide
