How To Kill Crawl Space Mold:

Other Mold Prevention Methods
Your first plan of attack is always preventing growth in the first place. To do this, you need to find out what is causing the moisture in your crawl space.
Check your dirt and your pipes. If your pipe is leaking, fix it. If the issues seem to be the dirt, you can place a dehumidifier or moisture absorber in your crawl space.
Here are a few other methods to help you prevent moisture in your crawl space:
- Add a plastic vapor barrier.
- Seal up your vents
- Protect your crawlspace from outdoor elements by building a barrier around your house.
- Think about installing insulation under the floor.
Is It Something Else
Youre in your crawl space and white mold seems like a probable conclusion, but could it be something else? If theres no musty or damp smell and the white substance is on a stone surface rather than wood, it could be a mineral deposit. We refer to this as efflorescence, and the salt deposits come from moisture.
If you mist a little water over it, it should disappear as it dissolves. While this may not be mold, it indicates the presence of moist conditions, which are a perfect breeding ground for mold.
Another possibility is mildew. While similar to mold in many ways, it is only a surface fungus, so its easily cleaned with a household product. Mold tends to be more fuzzy or even slimy.

Fight Mold With Ventilation
Once fungal growth takes hold, it thrives in the wet, stale atmosphere under your home. Ventilating the crawl space circulates fresh air through the area and holds down humidity. That reduces the concentration of air-borne spores, making it harder for mold to spread.
Power Tip: Make sure the clothes dryer vent terminates outside the crawl space.
Bleach And Vinegar Cleaner
If youre still interested in taking on the task of killing mold in your homes crawl spaces, you will need a cleaner that is proven to eliminate a mold infestation. Bleach and vinegar-based mold cleaners are a good starting place, as they have proven to be effective in eliminating the presence of mold. However, its important to wear a respirator when conducting this action, as your air quality will become dangerous to inhale once bleach and vinegar are in a confined environment. Consider airing out these environments after applying cleaners to mold-infected areas.

White Mold Vs Black Mold
The main distinction between white and black mold is that white-colored molds, sometimes known as fungus, are generally not considered harmful.
While species of molds that are black can sometimes be harmful to specific individuals.
However, it is essential to note that any mold species that are black, green, or white can cause an allergic reaction to some individuals.
Stachybotrys Chartarum, a mold species with a dark green to black color, is commonly referred to as black mold.
This species is believed to cause allergic reactions because it liberates a relatively large quantity of mycotoxins into the environment.
On the other hand, white mold does not release as many of these compounds, but it can still cause several health issues.

Why Are Crawl Spaces Prone To Mold Growth
Generally, the soil in a crawl space is drier than the soil around the foundation. This results in moisture wicking into the crawl space from the soil outside. Once inside the crawl space, the moisture evaporates into the air and the water vapor moves up and settles on ductwork, floor joists, subfloor, and/or floor insulation.
During the summer, the air and surfaces inside a crawl space are generally cooler than the outdoor air. As warm, humid air moves into a crawl space through the foundation vents, it begins to cool, resulting in an increase in relative humidity. Condensation from water vapor gathers on the ductwork, floor joists, subfloor, and/or floor insulation, and of course you know that moisture leads to mold growth.
