Vitamin B-12 tablets will help there. I grew up in a highly tick, flea, chigger, and mosquito infested area. My parents shoved B-12 tablets down our throats as soon as it started to get warm every year. We almost never go bitten, as long as we kept taking the daily tablet.

You’ll sweat it out, and B-12 is the smell you have associated with fresh baked bread. The tablets smell like a commercial bakery. Sweating it out gives your skin a slight bitter oder, and masks the smell of your blood.
