camo out from head to toe. long sleeved camo shirt, a netted face mask, etc... If you are camoed out, then the mosquitos / nats can't get to you very easily. Turkeys don't smell very well at all...it would be fine to spray mosquito spray on you, but I don't think it is neccessary to do so if you are camoed out completely. Full camo also helps conceal you from a gobblers eyes (servers multiple purposes).
