When I lived in Illinois, my neighbor was a retired Navy vet who spent her free time working on her yard.

Whenever she saw that we had moles, she’d come over with a shovel and offer to kill them for us. She would take a hose and stick it down the tunnel to flush the little guy out, then whack it with a shovel.

IIRC the hours she spent in our yard to moles killed was not in her favor tho
