Depending on which movement items are available, it is often safest to carefully kill each Kihunter from below before attempting to get onto its platform: lure the Kihunter over to the opening and spin jump directly up into it. If wall jumping up, do so from low enough that Samus bonks the opposite wall before touching the Kihunter: otherwise the wall jumping movement may prevent Screw Attack from taking effect.
