Don't know where you live but, hopefully, it will be cold enough that you won't have to worry about them pretty soon. Till then, tuck your pants in your boots (or tie them shut), button your sleeves and spray down with anything that works for you. Don't worry about the smell, just play the wind.
Fidgeting around, scratching and, losing concentration because of itchy bug bites will get you busted by deer quicker than the smell of the spray.
