Hogs will lay up all day in a cool wet area then move and feed at night, if you want to increase your chances of seeing hogs late in the evening before it's gets dark, find the cool wet places where they may be bedding down during the day and bait the area with flour / corn or anything that might keep them hanging around.  try using a hog pipe and set up a trail cam to find out exactly what time they are hitting the hog pipe, if it's strictly at night then get you a Destroyer Hawg light and shoot some pork at night.

Good luck, we had already been trying diseal corn, corn mixed with beer to get sour, and bread etc... The best thing that had been working was our hog pipe we set up in the sendero, but it would only get hit once or twice a month, then we tried the flour, it worked!!! Now that deer season is over we are going to focus primarily on hog hunting and trying to shoot a huge boar that is roaming our plcae and is estimated to weigh between 400 to 500 lbs, but is very smart and only comes out early in the am or during the night.
