No problems with bugs at these temps. Last year, during the early October bow season, my two sons hunted and tent camped the same area. Again, no bugs but when they returned to their tent following a day of hunting, the tent had been torn down by a bear. Needles to say, their hunt was cut short as they quickly packed up and skedaddled back to their truck. They were much more comfortable this year, camping with me in our new Oliver...my days of tent camping, during any season, are over now that we have the Oliver!
