Horse Flies

[Sabretooth]

I worked outside for weeks during the summer of 2013.
Mosquitoes and regular flies were bad, there was underbrush and tall vegetation on two sides of the building I demolished.
After an internet search, I found that spraying myself and clothing with blue listerine mouthwash kept those pests away.
Try this and let me know if it helps, good luck.

serious advice.....
