A good vet will give you a plan over probably a few weeks to kill ever stage of the worm... adult, larva, and egg. Its your best bet. Also, IMO, for preventative measures after the fact, a good vet will take fecal samples on a schedule to test for parasites and will only treat the horse for them if they are present to avoid immunity toward wormers.
