Possible chigger (red mite larva)

Leaf litter, grassy vegetation, gardens, and humid soil; larvae may attach temporarily to people and animals.

Larvae feed on liquefied skin tissue and tissue fluids; adults and nymphs primarily consume small arthropods and organic matter.

Larvae climb vegetation and attach to passing hosts, commonly causing intensely itchy bites after several hours. They do not burrow into skin and usually detach within days.

Bites can cause itchy, inflamed welts but chiggers are not established vectors of disease in most regions. Free-living stages help regulate small soil organisms and contribute to decomposition.
