There was something in my goats' stall. It was super tiny, could barely see it and black. The bite hurt like heck fire and itched intenesely then the itching stopped and a small red bump rose up. The bump does't itch too bad, nothing like a mosquito bite and goes away in a few days. I completely cleaned the stall, washed it out with bleach and water, limed it and put down fresh straw. So far, no more bites. I'm glad you got rid of whatever it was.
