Turkeys have very good eyesight and hearing but their sense of smell is less than that of humans. No cover scent is necessary. I've never worried about bug spray, I use a net camo mask and usually all my extremeties are otherwise covered by my camo clothes. Usually around here in both fall and spring season it's cool enough for me to wear at least a jacket. I only remember one time when it was so warm I needed to strip down to a tee shirt.
