On Christmas Eve I wondered if all of the running around up in the ceiling was Reindeer on the roof instead of the Rats. The pattern of the running around we hear still matches the sounds we have heard attributed to possums instead of rats. We wonder if the rats were over the main part of the house and the possums are over the eaves. We called the pest control people and they won’t come back out until the bait has been up for 1 month. 3 weeks now and the noise still goes on all night. They mostly just run around the inside perimeter of the house. Definitely is more than 1. Sounds like one is chasing the other all night long. We did sleep better last night though as we put in the bedroom furniture we had bought via ebay.
