The only thing that you have control over is whether the conditions in your home are favorable for the mold to begin growing.

Something that mold loves to hide underneath is your carpet. If the carpet is old (especially if you have it in the bathroom), you can bet there is likely to be something living underneath it. Not only does mold like to hide under your carpet, it will also make a meal out of it.

In order to reproduce, mold requires moisture, warmth, and food. The carpet provides part of the insulation that the mold needs to grow under it, so all that is left for you to provide is moisture either in the form of humidity or water spills that do not get cleaned up properly.

If you think that your carpet is moldy or mildewed, you can clean it with a biocide. Biocides are produced to stop things like mold and bacteria from growing where you do not want them to. Even if you use this, though, you will still have to remove the carpet padding underneath.

This padding is not cleanable and will need to be thrown away. If your carpet has been completely submerged in water and it is not just a small area, it is advised to just tear it up and throw it away, as well. Cleaning a room's entire carpet can be costly and it's possible that you are better off just getting new carpet.

While you are cleaning your moldy carpet, you should wear gloves. After it has completely dried, using a vacuum that has a HEPA filter on it should remove any mold spores that still remain in the fibers of the carpet.

Having wall-to-wall carpeting is not advised. If you already have it, you can reduce the chances of mold and mildew growing by removing your shoes before walking on it and disallowing pets to enter carpeted areas.

Using a good vacuum cleaner (with a HEPA filter) regularly will also help to stop mold from growing. HEPA filters are about 99.97 percent accurate in removing particles from your carpet and air.
