Your deodorant doubles as a mosquito bite itch queller. So far my best remedy is to put a metal spoon (t.) under hot running tap water for a few seconds then press onto the bite. Test it first with your finger to make sure it is not too hot.
How to stop a mosquito bite from itching: apply a few drops of apple cider vinegar, tea tree essential oil and witch hazel to a cotton ball and dab onto the mosquito bite! Find more natural remedies for mosquito bites: http://www.optiderma.com/articles/natural-remedies-mosquito-bite-itching/
