Well there is always Microbial Masters. They use an all organic solution to kill the mold that is healthy for humans, and animals. This makes it better than gasses and chemicals. It captures and kills all mold, even stachybotrys, within 60 seconds. It also does not take as long. They fog it into the contaminated area, basing the amount of product to use on the square footage. It is trully an amazing break in mold remediation. It is cost effective, and does not displace occupents as long as other methods.
