Just bend over to the little door! I forgot about that! Just yell "Be GONE" under the house and it's pretty much the same thing as a ritual to pass the poor thing over. Maybe you should wave your arms and hope for a clap of thunder after you yell it. But seriously, don't you kinda wanna remove it? Or would that be bad, bad, luck?
Once, when jan and I were looking for a reported kitten in an industrial park years ago, she, out there on her own one day, found a "bottle graveyard". It was literally about half an acre in the woods of old broken bottles. She, of course got all the neat ones! When she took me there a few days later, I found an intact cow or small horse skeleton in the woods. I took some bones cuz I thought they were "cool". A few weeks later, I noticed I'd been having a lot of plain ole' bad luck so it was suggested to me by someone to return the bones. this friend accompanied me out there and said some religious thing as I put them back and we hoped the gods would be glad and leave me alone! Well, we all have bouts of bad luck sometimes so I dunno if it was the bones or not but I felt much better returning them to whence they came!
