C.S.
Sounds simple but try just a baking soda and water paste- it should take calm the itchiness and help dry it out but won't sting and is all natural.
I can remember when I was little my grandmother pooring rubbing alohol on my legs. It stung like crazy and I would cry. My grandmother would tell me "if you'd stop scratching then I wouldn't have to do this". It was awful but it kept the infection away, helped dry the bites and made me think twice about scratching :) But I would try the baking soda!
