Dust your birds with mite powder or Diatom, sprinkle ant powder in the nest boxes & dust bath if you have one too, so they treat themselves. You could use Harkamectin instead, or Frontline.
For the redmite, the most effective is to spray the coop with FicamW. Make sure you read the instructions carefully & use protective clothing, etc. as it's toxic stuff but IMO, better than all the rest of the redmite treatments put together!
Happy in Hampshire!
