The Role of Enzymes
When chiggers bite, they inject digestive enzymes into the skin. These enzymes liquefy skin cells, creating an opening called a stylostome. This process is what causes the intense itching.
Skin's Reaction
The body's response to chigger bites includes inflammation and irritation. This reaction is a result of the body's immune system trying to heal the damage caused by the enzymes.
Why It Itches So Much
The enzymes and the feeding process stimulate nerve endings in the skin. This stimulation is what makes the itching so severe and bothersome.
