Km: KILL THEM! Seriously, if every runner killed ever horse fly that landed on them, I think we might make a dent in the population. Ok ok, not really, but I really HATE horse flies. They take over Umstead for like 3-weeks every summer, and we just started marathon training, it just seems unfair! So, as I am not about to not run in Umstead for the next almost month... BUG SPRAY! I read through the thread, and couldn't stop laughing at some of the comments, and about halfway down I realized that they were talking about horses and not people.
Unfortunately, I tend to believe what that grad student in entomology said... bug sprays are not effective against horse flies because they're too freaking big and you'd need a dose that might harm small kids (or small runners). DANG IT!
