When asking for chigger advice, be forewarned that someone is going to bring up remedies involving "choking off the air supply to the chigger." Usually this involves putting nail polish or some other substance that produces a hard, air-tight cap over the bite site.

But in reality, by the time you get the red itchy bump, the chigger is long gone. They are a tiny, tiny critter, and it doesn't take them long to drink all the liquified skin from you they need.
