My hibiscus bush forms many flowers and is thriving however the flowers frequently fall off soon after and often before they even open. Or... maybe its critters?

Sounds like a flower bud worm. An adult fly or wasp lays an egg on the unopened bud, the egg hatches into a larvae which each the insides of the flower before it can open. Since it's inside it's protected from insecticides and it's really difficult to control flies or wasps so I can only suggest you prune off the flower buds that are affected to try and stop the lifecyle of the pest. It will stop damaging the flower buds a little later this summer. Best wishes with your plant~
