Update:
Went to bed, closed all the bedroom doors.
Woke up, went on with day until child yelled " I FOUND IT !!!!!!!!!"
It had tried to crawl under the basement door. We THOUGHT it was dead, threw a towel on it and went to get a shovel.
Came back and it was GONE.
Searched the basement and found it. Knew it was on its last leg, but it was in a place I just could not (and did not want to!) get him.
Yeah for friendly neighbors who will catch your bat. I am forever indebted.

Our house is once again safe.
