Lightly tap the bites with the spoon until the spoon cools enough that you can hold it against the skin without burning yourself. Repeat until bites no longer itch, then apply hydrocortisone or other anti-itch cream. You may have to repeat the process for a few days, and it sounds like you're covered in them, but I have found this to be very effective at treating chigger bites.
