I bet most people who are saying don't kill it don't know the damage they can do to your home once they get in and start reproducing.
We had a horrific time.
They burrowed from the garden into the house through a gap in the brick work.
There were at least ten and they would run about in the walls, between the floorboards, chewed wires, chewed furniture, pissed everywhere so the house stunk, shit everywhere. It was truly awful.
We tried humane traps where they can be released back outside, then tried snap traps, bait boxes, nothing worked.
We had pest control deal with it using very strong poisons and it was dealt with very quickly.
I feel no guilt after my my house and in particular by baby boys bedroom was completely taken over by horrendous smells and scurrying about.
