i think it depends alot on what is added to the bait, as far as just some meat in the hole i has this one time, i had a large 5000 head hog finisher complain about coyotes, he did not care about their presence as much as the mess they made, i went out to his dead pile to look and their was thousands of pounds of dead pork laying around from 40 pounds to 240 pounds at a lump,the coyotes were eating a little of the fresh pork but where they really caused a problem was where he would cover the pile up every couple weeks with dirt from his loader, they would then dig enormous holes into this fresh dirt and crawl into this stinking mess and tear out chunks of rotten pork, drag it off a ways and eat the meat leaveing bones scattered all over the farm, some even on the county roads, i shoveled the holes shut to stall for time as it was 2 weeks before prime up, they dug them back out, the owner mixed in barbed wire with the dirt and filled the holes and they dug new ones, the stench comin out of these holes was awesome, after 2 weeks i finally set the section up, and nailed lots of stinking and i mean stinking coyotes, cut them open and they were full of that rotten pork, i got every one of them on getzens bait in dirtholes, and anybody that ever used getzens bait knows it stinks worse than ten piles of dead hogs.
