CK, the first rule of thumb for remote field work -- for both men and women -- is to eliminate all commercial oders from bathsoap, shaving lotion, deodorant, perfume, hairspray, etc.
Buy UNSENTED deodorant and soap. And don't use the other products when you plan to be in the field.
It will cut down on the bothersome flying predators. Multiple layers of DEET on top of multiple layers of scented projects tend to cancel each other out. Deet is not safe in excessive doses, beware. Americans always think that 'more is better' but it isn't in this case.
In Australia the flies were horrific in some areas. We used netting over hats that tied at the neck. That worked very well along with care to eliminate scented personal products.
