In most states, woodchucks can be hunted most of the year with no daily or seasonal limits.
You can shoot woodchucks with a small to medium caliber rifle. Simply observe a burrow, favorite basking spot, or patch of grass and wait. Late afternoon/early evening is an ideal time to hunt woodchucks.
Where legally allowed, use of lethal trapping methods (body grip traps) set in the burrow, may also be considered to control woodchucks. This should be done by professional nuisance wildlife trappers to avoid killing non-target animals.
Box traps may also be used. The captured woodchuck can be euthanized using a carbon dioxide chamber or shot using a .22 caliber pistol or rifle. Shoot the animal in the head unless it is to be tested for rabies.
Commercial gas cartridges are fumigants that are registered for the control of burrowing animals. These cartridges have cardboard cylinders filled with chemicals that burn slowly and produce carbon monoxide and other lethal gases. They are ignited and placed in the burrow of the animal after all of the entrances/exits are sealed. Follow the labeling instructions carefully. Due to potential fire hazard, do not use gas cartridges near buildings, wooden sheds, or near any combustible materials.
