Not to overload you w/info., but Safeguard goat wormer is another one often used for a variety of worms, including roundworms. Dawg knows his stuff, no doubt about it. I've been lucky in only dealing w/worms once, and the Wazine seemed to "fix" things for me, so I won't knock it. I do keep Safeguard on hand just in case though.
Many use Adams Flea/tick spray or Frontline (for cats or dogs) to treat mites, if you're talking feather mites.
I've never tried deep litter method. Many swear by it, but it just grosses me out, thinking of all that manure piling up. You might do a search on "dropping boards" if you're considering going a different route.
We've all "lived and learned" with our birds to different extents. When they're pets, those lessons are hard ones...
