Horse Fly Problem

[Sambosu]

Every morning and evening my calves are attacked by horse flies.  My bronco fly spray does not keep them off.  Does anyone know how to get rid of them or keep them off my calves?

Bronco does nothing but make you think it does.  Placebo effect.  Go get some cv80.  It'll cost you, but it is the only thing that truly works.  Otherwise your sol unless you want to stand around and kill them all
