Common Types of Mold in Homes
Aspergillus – Aspergillus mold is a very common type of fungus typically found indoors and virtually all over the world. Allergic aspergillosis is a condition that occurs when people inhale the microscopic spores of aspergillus, causing an immune response in the body that can include a high fever, asthma attacks, and coughing up blood and mucus.
Cladosporium – Cladosporium is a type of mold often found growing inside homes. While most types of mold prefer warm climates, cladosporium can grow in cool areas, too. It often grows on fabrics, like carpets, and on wood surfaces, like cabinets and floorboards. It can cause a variety of respiratory problems.
Chaetomium – Chaetomium is said to be the third most common type of mold found in damp buildings. It can be found on all sorts of water-damaged building materials, including wallpaper, drywall, window frames, baseboards and carpets. The mold produces an enzyme called cellulase, which breaks down the cellulose in these materials, literally destroying them.
Ulocladium – Ulocladium requires a lot of water, so it frequently grows in areas with extensive water damage, including homes that have been flooded. It’s often found growing on wet walls. Many people are allergic to ulocladium.
Fusarium – Fusarium is another of the mold types that, like cladosporium, can grow and spread at lower temperatures. It’s often found growing on water-damaged carpeting and other fabrics. It causes allergic reactions, asthma, and respiratory infections. People with compromised immune systems are particularly vulnerable to infections due to fusarium exposure.
Penicillium – Penicillium is often found growing on materials that have been damaged by water, including carpeting, wallpaper, insulation, and furnishings like mattresses. It’s one of the mold types that spread quickly and easily from one part of the home to another. Exposure to penicillium can cause allergic reactions, chronic sinus infections, and inflammation of the lungs.
Stachybotrys – Stachybotrys is often referred to as “black mold” due to its slimy black appearance. It’s sometimes referred to as “toxic mold”. It can cause allergic reactions, breathing problems, chronic sinus infections, asthma attacks, fatigue, and depression. Stachybotrys has a characteristic musty odor and usually grows in places that stay damp all the time, like in air conditioning ducts where there is a lot of condensation or around leaky pipes.
Efflorescence – Efflorescence are often confused with white mold in basements. Efflorescence is a crystaline, salty deposit that occurs on the surfaces of bricks, concrete and other masonry products. Water from the grounds surface can often be the cause of efflorescence.
