Yep, but it's a mature colony by now and it's in a hole created by another creature, with all sorts of nooks and crannies. Try dumping bucket of soil over it after dark, once they are dormant. Then look for the next hole they find to exit and repeat.
On the bright side, it's been there all summer and no one's been injured.
