I have trapped so many raccoons in a 30+ year period that I could've made Miss Judy a full-length fur coat with matching hat, handbag, and slippers...with plenty of pelts left over.
It's really quite simple. I've always used a live trap. With raccoons, just about any bait will work, e.g. canned cat food, tuna, dry cat food....heck, I've even used chicken bones from a batch of Buffalo wings I had for lunch. They all seem to work.
With raccoons, unlike with skunks, you can walk right up to the cage and put a CCI subsonic right in the brain pan. (NOTE: With a subsonic, your neighbors won't even notice.) The problem is when well-meaning but misinformed people trap them and then relocate them. All that does is make the raccoon trap wise. They'll then approach the trap, enter, and reach over the trip pedal, grab the bait and back out. You can remedy that, however, by constructing a small wire mesh bait box and hang it inside towards the back of the trap. As the raccoon tries getting the bait out of the bait box, it will almost always step on the trip pedal.
Any way you look at it, raccoons are considered by most state fish and game departments as "varmints." Here in Utah, they are one of the animals the state forbids you to release when you catch one. They must be dispatched.
Good luck in your efforts.
