hah! It never effects the deer in my area, to tell the truth they always go rite up to it and sniff it. Last year i took my lil cuzin out wit me and he shot a decent doe. Next day i myself went out and killed a Huge doe that went rite up to the gut pile, stood broadside sniffing it, and i put a arrow in her. So i guess its just my place but it dosnt effect them one bit.
