My tub trap is under the floor in an extremely shallow, unheated crawl space. My house is up on peers and the crawl space floor is dirt with the skirting of the house coming down to the ground. It is too shallow for anyone to get in there and insulate the skirting. I want to try to live in the house this winter- I have only used the house as a summer house up till now. I am worried my trap will freeze. I'm in northern NY.
