Baby Teething Gel will stop the itch. It numbs the itch. Also the old Bactine Itch Relief worked on contact, it's formula has changed so it's not as good now. I grew up in the woods of AR. I know about chiggers! Every night during the summer we put a product called Germ Trol in our bath water. One bottle cap full. Our bath then wasn't a tub full of water. It killed the chiggers before the itch got bad. It was a Stanley Home product sold at home parties like Tupperware. Every house had a bottle of Germ Trol. The last newer bottle I saw of it, it wasn't the same at all.
