How to Find out If Fungus Is in Your House

Mold often grows around leaks.

Fungi, also known as molds and mildews, are microscopic organisms present almost everywhere. However, fungi can damage homes and present a health risk to occupants. Prevent fungus by keeping the humidity low, improving air circulation and fixing any sources of moisture, such as leaking roofs. You can clean up small amounts of fungus yourself, but contact a professional if you have large amounts of mold or mildew in your house.

Things You'll Need

• Household bleach

Instructions

1. Inspect your home for signs of discoloration, especially near damp areas such as showers and bath tubs.

2. Place a drop of bleach on any discoloration you find. If it disappears, the discoloration is probably mold or mildew. If there is no change, the stain probably has a different cause, like minerals in the water or smoke from the air.

3. Check for a musty or earthy smell, especially in dark, damp or poorly ventilated areas. A musty smell is often caused by fungal growth.

4. Look for water leaks and damp areas. Fungi is likely to grow in areas of your house where there are moisture problems.

5. Check ceilings and ceiling tiles for water stains, which indicate a leak. A leak that is left unrepaired can promote mold growth.

6. Periodically check areas around your home where pipes run, such as under sinks, behind washing machines and the water supply for a refigerator's ice maker. A leak in these areas can go unnoticed for months, causing rotted wood and sheet rock, and providing the perfect conditions for fungus.

Tips & Warnings

• Wear a mask, gloves and safety goggles when you are cleaning up mold. Dispose of any old rags you may use when removing mold.
