These are all good answers and effective nigger bait. The thing you want to keep in mind is what season it is and where you are trapping niggers.
For example, watermelon works great in the summer whereas a fat white woman works better im the winter months.
While downtown in a large city has the biggest population of niggers, it also can be unsafe. The last thing you want while nigger trapping is a pack of feral niggers attacking. I advise going out towards the suburbs and staking out a liquor store or gas station. If there is legal weed, a dispensary. Scratch tickets or menthol cigarettes are excellent bait for these areas.
Remember to set up a good nigger blind while waiting to trap a nigger. I suggest sitting in a vehicle with the darkest tint on the windows as possible and play rap music with the bass turned all the way up. The niggers will just assume you are one of them and drop their guard.
Good luck! Happy hunting!
