Wisconsin laws:
Non-submersion (dry) Set: non-submersion sets must be attended and checked in person at least once each day and any captured animals must be removed from the set, except that weasel boxes may be checked every four days given that:1. the entrance hole is no greater than 1â…œinches in diameter;2. the enclosure set must use a body-grip trap (for weasels this includes a foothold trap and rat snap trap); and3. the enclosure is securely anchored to an immovable object. Water Set: water sets, except submersion sets, must be attended and checked in person at least once each day and any captured animals must be removed from the set.Submersion Set: any trap set capable of capturing an animal and capable of submersing the captured animal. Slide wires or poles, locking devices, slip chains, weighted traps and traps staked in deep water are commonly used in submersion sets. A body gripping trap is not a submersion set when more than one-half of the set trap is located above water. Traps must be attended and checked in person within a 4-day period following the last tending of the set. Any captured animals must be removed from the set unless it is an under ice set. You must monitor water levels to ensure effective submersion sets. Under Ice Set: there are no mandated trap checking periods for sets made under the ice.
You may not molest or take traps, cable restraints, snares or trapped animals that belong to someone else.
Interference with Trapping. No person may interfere with lawful trapping with the intent to prevent the taking of a wild animal: Harassing wild animals, impeding lawful trappers or disturbing lawfully placed traps, among other actions, may constitute unlawful interference.
Stealing or molesting traps, cable restraints, snares, animals or the contents of any lawfully placed trap, cable restraint or snare is a criminal act and is punishable by fine ($300-$1,000), imprisonment (up to 90 days) or both and a mandatory 5-year revocation of license.
