This building is over 60 years old, and it was constructed with used lumber in the first place. Its dry soft old pine of some kind. This place was built by just putting it up, a lot of odd spacing on framing members and studs.
The back foundation is constructed of rocks and mortar, a lot of spaces in there. Last summer I placed 1" foam panels on the outside foundation and they tucked under the siding all the way around. This gave me r 6.5 and makes the stone and mortar foundation somewhat of a thermal mass. I was really worried about the new plumbing freezing, I also sprayed Tiger Foam all around inside the foundation. The heat from the stove must be radiating very well into the crawlspace down through the floors, I just put in a tile floor in the kitchen area where the stove is, and refinished the hardwood floors in the living area last year. It's been holding around 50* down there.
I found a reproductive ant with wings and it's definitely a carpenter ant. The walls are only dead air space, they might be in there, sux.
Anyway, I just got out from under there, I'm not highly claustrophobic but it's nasty. I went around the perimeter and emptied 2 bottles of Home Defense juice; and gave them another fogger bombe surprise for dessert.
I have a few pounds of boric acid, I might hook up a shop vac with an exhaust port I have, and see if I can blast it all over the foundation down there somehow.
I'm still fighting with a few roof leaks, have to correct those problems in the spring.
Clordane???? Why do they take all the good stuff off the market......
Thanks again for the help!!!!!
