Raccoons aren't that finicky, not to worry. They can become trap shy, but bright and shiny...that will actually attract raccoons.
For example: A solid raccoon set that has always worked wonders for me was a simple little stream set. Walk the banks of the stream looking for raccoon sign. You're also looking for a point where there is a rocky bottom forming a shallow riffle in the stream and sign that the raccoons have been working the shoreline looking for food. These are very common locations where raccoons hunt for aquatic invertebrates, like crayfish. When you find a location that fits this, take a 1.5 coilspring and put aluminum foil over the pan (shiny side up) and set the trap so it is about 1/2 inch to an inch under water. You want this trap to be tuned to fire fast. Bed the trap firmly so there is no wobble, in fact bed every trap firmly so there is no wobble, including cage traps. Hook the chain of the trap on a one way slider and anchor the slider in deep water. Raccoons can't resist trying to find out what is that shiny thing dancing under the water in the riffle. Next time that raccoon comes down that stream and starts hunting that riffle, you'll find him the next day at the end of the slider in the deep water. Grab the slider, pull the coon, reset the trap and catch the next one.
Nice thing about this set is that it takes the coon away from the trap location, drowning it in deep water, and keeping the set from being tore up by the trapped coon.
If the raccoons are not hitting your cage trap, make sure first that the trap is bedded firmly. There should be no wobble, no animal will work a set if trap is not firm and wobbles. I use a flat nose shovel to scoop out the trap bed for cage traps. Then Bait the trap with something that raccoons can't resist and wire the trap open, so that it can't close. Raccoons will start hitting the trap, check it each day and when the bait is gone you know they're hitting it. Keep the trap baited and let the raccoons keep hitting the trap each night for 3 - 4 days or do. Then when they're hitting it like clockwork, unwire the trap and set it.
What ever has been hitting your cage trap for the past few nights should be sitting in the trap the next morning.
Raccoons like to travel in groups. If I have a raccoon problem, I'll gang set with 3 or 4 traps at each location along their travel route. Get's the job done in one or two nights, instead of one or two weeks.
