Mine were hitting late too but i found i was using the wrong bait try some scraps from the butcher and some raspberry jello powder

How far away from the bait site are you? Answer this question and I will give you some idea's. Need to know if you can go to it every day.

sure can yep i drive thier everyday when I'm hunting its about 45 mins away by truck

I can't get there but on the weekends. I am 100 miles away. Ocassionally get there during the week when work permits. Have 5 baits out, all getting hit, but 4 out of 5 are late. The one getting hit is a small bear. Using bagels, grease, candy, molasses, cookies.

There are several suggestions.

There is using a radio. A small transitor. Turn it on low at night and turn it off first thing in the morning for several days.

There is if using a barrell close it up during the night and open it up first thing in the morning. Do that for a few days and the bears will be fighting over who gets it.

There is if having multiple bears hitting limiting the bait you put out so there is more of a drive to get to the bait first and the dominant bear or the bigger bear will more than likely come to it or stay closer to it.

There is using a cow bell with a long rope attached to it so every time you leave you ring that bell and the bears will get used to hearing it ring and know that the person left. Do that for a week or 2 to get them used to it. Then when the time comes for you to hunt it 2 guys walk in the 1 guy walks out and rings the bell and they think no one is there and there you have bears coming in.
These are some tips I learned.

But most of these are for if you are close to the bait site and can put bait out or do some of the things I mentioned. I also live 3 hrs from my bait site and I am limited to when I can go up to it.
How long is your season?
If it last till in October like our season does then they will start feeding in the day time because then it will start getting snow on the ground and they will want to just sit there and feed. I usually feed them till the last week of the season in the spring because then there will be alot of bears there and they will want to just eat.
Good luck and keep us posted how its going.

i find the bears around here are gettin a little smarter
