You probably should invest in one of the small 'Hav-A-Hart live traps. They're Just the right size for rodents like that. Use sun flower seeds or peanuts for bait. When you catch it, you'll have to release it a good mile or more away or it will find it's way back. And, you'll have to destroy the scent of the hole(s) or another will quickly take up this 'ready made' residence. Dropping a moth ball down the hole and covering over with soil worked for me.
