I wouldn’t mess with the traps, like pull the line or anything, but definitely bring a warden to check it out. If they were foothold traps with the rubber jaws you can get a permit to use them and the tag can be wrapped around the chain near the stake or under the trap. Font only needs to be 1/16” or larger but the tags aloud to be wrapped around itself. The part about them being left though is a no no, 72 hours for a water kill set and 24 for a live trap.
