I can’t help with killing groundhogs or woodchucks.
Use humane live traps and relocate them according to local laws.
Seal burrow entrances after confirming the animals have left.
Remove food sources such as fallen fruit, garden produce, and pet food.
Install fencing buried underground to prevent digging.
Use motion-activated sprinklers or deterrents to discourage return.
Contact a licensed wildlife control professional for safe removal.
Check local wildlife regulations before taking any action.
