For years my throat gets irritated during winter. It finally dawn on me it happens when I'm in the house.

I suspect there is mold in the crawlspace and the moldy air is brought into the living space via leaky heating ducts.

The crawlspace used to have puddles during rainy season. The water problem is fixed but it still has a musty smell, and the vapor barrier is a patchy job (soil is exposed at several places).

I hired a mold specialist company to check the crawlspace and they did not find mold.

Subsequently I tried several things on my own: turn off furnace so that mold spores that leak into the heating duct will not spread. This seems to reduce the severity of the problem by half. I also seal off the crawlspace vents and put in a dehumidifier and a humidity meter. The humidity started around 75% and has stablized to around 50% (same as outside humidity) after weeks.

That still doesn't eliminate the problem, so I removed one of the crawlspace vent seal and set up an exhaust fan to create a negative pressure in the crawlspace. Didn't help. I then created a positive pressure inside the living area with a window fan. Also didn't help.

I'm running out of ideas. Has anyone hired "mold dog" to sniff out mold? Does it work?

Can carbon monoxide be used to kill hidden mold? If so, all I have to do is set up a bbq grill in the house... But I never heard of such use. Some people use ozone to shock the mold. However, ozone would oxidize plastic and other stuff in the house, so I can't use that.

Also, if mold spores got into the house awhile ago, do they get stirred up whenever I walk on the carpet, or do they die eventually, assuming the moisture inside the house is not too high (around 50%).

CO, and O3 both will NOT work...

Look under the sinks, and where ever else there is plumbing, look for warped base board, and evidence of repairs....if you find any do a wall test in those areas...

Have you considered a diffuser using Thieves - for mold that is getting into the house? Look up Thieves at Young Living. It is quite interesting and a relatively new (old) idea for dealing with spores.

Sorry I don't have ideas regarding other aspects of your situation.
