Put regular Listerine (the green kind) in a spray bottle. Spray about a half an hour before you go out. I know it sounds strange, but ever since my mom told me about this, my kids never get bit.
I have also heard that you can rub dryer sheets (Bounce) on you before you go out. I never tried this one but heard it works well. I am also one of those people that never get bit, but my poor daughter used to get attacked before I tried the Listerine. Good Luck!
I’ve heard Listerine works.
