text: every summer i get bit up by fleas even though everyone around me is unaffected. what's up with that? i'm also really sensitive to the bites getting big itchy welts. yep, i am the same way. it has to do with our blood type or scent or something. i'm guessing that you are prone/sensitive to getting bitten by all kinds of bugs, as i am. stay away from bananas (attracts) and increase garlic (repels).
