Once every 6 months I boil up a big pot of water , put 4-5 whole cloves of garlic in it and then put the lid on and turn it off. Let it seep for 24 hrs and then fill up the water dishes with it. They love it. Garlic is high in sulphur. I also use a conventional wormer. The other way to administer garlic is cut the leg off an old pair of stocking place a whole garlic in the toe and hit it with a hammer. Tie the stocking so that it hangs in the water.
I also sprinkle orchardists sulphur round the nesting boxes every time in clean the coops.
These are of course preventative measures, if I find lice or mites I hit them with the ' big guns '. Vaseline on legs, pestine entire body( especially under wings and around vent ). Clean the coops down and spray with coopex insecticide ( available in the garden section at the hardware ). Pay particular attention to the roosts and nest boxes. You have already found the best way to detect lice. Carry your birds around for 10 mins or so and if they are infested you'll have them crawling on you in no time. Don't worry they don't live on humans, have a shower and wash your hair and that will send them packing.
