Tryon / Polk County North Carolina - How bad are biting bugs ?

Hello everyone, I would be VERY thankful for some help.
We will move to Polk County, NC next year.

As I keep my horses outside 24/7 it is very important for me to know whether that is possible in that area ? How bad are Deer flies, horse flies, ticks and any other bugs ? How long is the season ? Is it possible to ride outside during summer or are you and your horse being eaten and bitten all over ?

I have lived in an area that was so bad ,if you open your front door and make a few steps outside the deer/and horse flies are all over you, riding during the summer months outside- impossible, horses on pastures go crazy.

Please give me as much information as possible, THANKS !!!
