Joanne,
Antifreeze is what they call a broad sprectrum herbicide/fungicide. It kills mold, fungus, plants, etc. It will also kill animals. I spray it on all my crawlspace wood that is not pressure treated. I also use the borax even though I have only seen it specifically recommended for termites and I don't have termites. I'm hoping it will work on powder post beetles, too, which I do have. Antifreeze will eventually soak into the wood and dry but if moisture is present in the future, it will reactivate. With the MAJOR rot I found in my crawlspace (I have replaced the entire floor and 3/4 of the joists and all the beams) I am not taking chances. I sprayed everything with glycol/borate (antifreeze is ethylene glycol) and put down 2 layers of poly sheeting. The house stood for more than half of its 109 years with rot, I figure it's now ready for 200 more.
