5. Scent Control
Although your average black bear is fairly tolerant of human scent around a bait, if the wind is wrong, they can tell when you are there and when you aren't. This often doesn't faze a young bear, but most mature boars won't come in if they smell you. Unless you have photos of the bear you want hitting the bait, leave it alone, and only go in to place bait. If you spend too much time there, the area becomes saturated with your scent, and the bears you are after will move on. Also, check the wind direction before you go to hunt. I often check online forecasts for wind direction the day before, or the same day I plan on hunting. If the wind is blowing toward where the bears come from, stay home and wait for better conditions.
