Sorry to hear that you have itchies near your eye - nasty!
Sulphur (sp?) powder is supposed to work to kill (smother?) the horrid things.
Chiggerex ointment (which I bought at Walmart) really helped to subdue the itch. They are "supposed" to bite us on the torso, or wherever elastic clings to the body. Don't your chiggers know nuffin?????
I always thought they were a Southern thang, until we got some in a load of bark chips. Now they have made our deck their home.
