How Do Chiggers Affect People and Do Chiggers Suck Human Blood?

Chiggers can cause a rash known as chigger dermatitis; the skin, especially of the legs and waist, is speckled with rather large, raised, red spots that itch ferociously and are caused by the feeding activity of those tiny mites.

Chiggers do not suck blood and, contrary to popular belief, they do not burrow in the skin.

They inject an enzyme that digests skin cells and thus eats a long narrow tunnel down into the skin.

The tunnel is lined by hardened secretions that are a part of the skin’s defensive response.

The chigger sits at the upper end of the tunnel and ingests the partly digested skin cells that are within it.
