Need help fighting those tiny flies/nats

[lucky2hunt]

Lots of guys on this site have said thermacell works....I haven't tried it, but sure sounds like a good option.

This disclaimer is printed on every Thermacell box and even the Cabelas website (where I copied and pasted below statement):

 

This ThermaCELL Mosquito Repellent is not designed to run at altitudes above 4,500 feet. The manufacturer states that units become difficult to start and run at altitudes above 4,500 feet above sea level.

 

I have tried the TC here around Flagstaff, it seems to start once or twice but then after that I cannot get the unit to ignite. I called the customer service dept and they pretty much quoted the above statement... Used the same unit in Kansas and Illinois and worked perfectly.
