I have heard about this home made scent killer but does anyone know f it will really work? Just seems like a whole bunch of trouble when you can buy it in a store. I buy the combo pack of Scent Killer with the big bottle and the field bottle for like $12. I've had several deer within 25 yards with the wind blowing in their face and was never detected. Never had a problem with it and it usually lasts the majority of the season.
