Well I suppose that's a horse of a different color then!
Overran by deer and allowed to bait? Gotta go with corn on that one. Course I've never baited, other than for bear, but I doubt a deer would go for spaghetti, frozen pie or dead beaver!
Of course when I hunt for a new stand placement I'm looking mostly for white oaks with lots of acorns. They prefer those over the reds around my area. There's another product called Acorn Rage posted all over TV also. That may be another good one to try? It's a deer's natural food source around here. Not sure in Iowa though?
I hunted several years in Maryland and you were allowed to bait on private land. Hunted over a corn pile for a couple days and didn't see anything. Went back to public land and used common knowledge and the lay of the land to shoot a nice buck. I guess it just wasn't natural to me to be hunting over something like that since I never have for deer. Hopefully some of the MD folks will chime in on this one and give you a better perception. I've never used either so all I have is a biased opinion on what I would consider "bait". It
may work but it looks like a gimmick to me!
