When I was trimming down some weeds around the house I noticed a 2" hole under the chicken wire I'd put down near the clean out pipe 2 falls or so ago when I had a rat dig under my house to get into the cellar. As soon as I saw that I thought "oh no, not a rat again!", but I don't think I have another rat. It looked like a rat had tried to dig its way out of my cellar like when I would plug up holes under the house that it dug because it was a 2" hole but that must be a coincidence. I think it's just some earth that settled due to the plumbers not filling in around the cleanout pipe when they upgraded my plumbing to PVC several years ago. So I tamped it down and filled it in with new earth. I will keep an eye on that spot but I don't think I have any rodents in the cellar. There would have to be a new entry hole that had been dug somewhere around the foundation of the house, and there isn't one. There no way a rat has lived down there for 2 years with no water or food. I have mouse / rat food down there and nothing is touching it at this time.
