Last year, I had one of these playing house above the front-yard water faucet. I had never seen one before.

Yes, I know they're harmless and even beneficial, but I started to have dreams about it. Definitely un-good dreams. So I gently relocated it to a lovely patch of trees in the local park.

Because it was either that or take off and nuke the entire site from orbit. It was the only way to be sure.
