I am in the middle of a lot of outdoor work. The horse flies are ferocious, abundant, and apparently I am delicious. Any tips or hints for combatting them? I have noticed that if I wear a white t-shirt it attracts them faster. In any case, I am forced to wear socks, long pants, a hat and a long sleeved shirt.... and it's hot! Heeeeellllppp meeeeee!
