I'm embarrassed to admit that I just today learned that chiggers do not burrow into your body, causing that infernal itch. Rather, the intense itching from a chigger bite is primarily caused by your body's immune reaction to digestive enzymes in the chigger's saliva.
Chiggers are the tiny larval stage of certain mites. They don't burrow into your skin or suck blood ---- which I'd have bet a thousand dollars that they do. Instead, they attach to the skin (often in areas where clothing is tight) using mouthparts. Then they inject saliva containing proteolytic (digestive) enzymes that liquefy nearby skin cells, creating a feeding tube called a stylostome. They feed on the dissolved tissue for a few days before dropping off. Neat,huh?
It's the enzymes and the stylostome that remain in the skin even after the chigger leaves, triggering the reaction, because your immune system detects the foreign enzymes and saliva proteins as invaders. This leads to Inflammation and release of histamine (and other chemicals), which causes the itching, redness etc...
All I know is that I hate them with the white-hot intensity of 10,000 suns.
EDIT: I changed the photo accompanying this text after being informed that the first photo was of a velvet mite. It was identified online as a chigger but apparently I don't know my mites. My mistake!
