I have a pest company treating the crawlspace for powder post they will be using a sprayer truck with about 15 gallons of water. My concern is with the rainy and cold weather the relative humidity will be too high to effectively dry the wood some members are over 100 years old and have some dry rot or age. Is it best to postpone this treatment when it is warmer and drier? Do not want a lot of moisture in the crawl for too long. It's vented crawl about 1500 sq ft?
If the crawlspace is well vented it should be able to dry out after a Boracare application. Boracare is designed to absorb into and bond with the wood itself, using the glycols of the Boracare to penetrate all the way into the wood and replacing its natural moisture content with the borate particles. You could run a box fan or small dehumidifier under there for a week if you wanted to try to help reduce moisture further, but you shouldn't have to worry about the higher humidity with the rain impacting it greatly. If you wanted to be absolutely certain you could wait until warmer/dryer weather, but it wouldn't be necessary.
