This summer I have been mowing weeds in some pastures for my neighbor Jeff, pulling an old Dunham rotary Cutter behind the Farmall H my dad farmed with for 45 years. It would occasionally hit my right foot with a piece of a weed, and leave a few pieces scattered on the deck of the tractor, but I didn't think anything about it. Sunday afternoon however, Chigger bites started showing in several places. 
When I was talking to Jeff and mentioned it he said to put New Skin (also sold as NU-Skin) on them. It works good, though is best if you out it on the bite as soon as it starts itching, and before you scratch it. Applied quickly the itching subsides in 2 or 3 minutes and the swelling is usually gone the next day. New Skin is on the same shelf as Band aids in most pharmacies, Walmarts, etc. New skin comes in a small sturdy bottle that can easily be carried in your pocket without breaking, though it is a little more difficult to carry someone to put it on the places you can't reach.
