For our Canadian friends, we don't have basements in Cali, and we have crawl spaces underneath our bottom floors which critters can find many access points that you are not aware of.


Well up here, so far north, we like to dig into the permafrost and hollow out little burrows to keep our beer.
Incidentally, any little holes at the bottom of one's house would allow cold air to come in during the winter and freeze the beer. As such, Canadian builders decided long ago to seal and insulate walls as best as possible so our beers do not freeze...and to keep energy costs reasonable.
I guess that thought concept hasn't hit some California builders yet, though i understand their brownouts are good fun.

Good luck with the rats.
We had some issues with a common grain moth in our pantry for awhile. They kept coming in with the dry goods or produce from the store. The solution was simply cutting off the food supply and zip bagging any grains, seeds or flour.
There's likely some dormant cocoons still in the walls.
