4 Most Common Types of Mold in Homes

Household mold is an all too common occurrence that can cause major issues for anyone living with it. While many different types of mold can grow in many different places, here are a few common ones to watch out for in your home. These are some of the most common types of mold in homes and how to identify them.

Penicillium/Aspergillus

While many molds require active water intrusion, penicillium /aspergillus can thrive either in dry conditions or with moderate humidity. Human impact from this mold may include allergy-type symptoms such as hay fever and asthma, hypersensitivity pneumonitis, and various respiratory irritations and infections. It is most commonly found growing on household dust, wallpaper and wallpaper glue, fabrics (including carpet) and moist building materials. Colonies may range in color from grey to white, plus various shades of blue or green.

Cladosporium

Generally considered one of the most common molds worldwide, cladosporium produces the same symptoms as the penicillium/aspergillus cited above, in addition to symptoms such as dry skin, hives and a postnasal drip. Cladosporium will grow on many substrates, including textiles, wood and moist window sills (check windows for interior condensation), and has a wide temperature-range tolerance. Colonies may range in color from white, to olive green, to brown, to black.

Chaetomium

Chaetomium is a marker mold, meaning that it is an indicator of water intrusion. It will produce allergy-type symptoms such as hay fever and asthma, plus a nail infection known as onychomycosis. It may also produce symptoms such as memory loss, balance issues, acid reflux, headaches, nose bleeds, and fevers. Indoors, it will grow on virtually any substrate that may be moist, and is commonly found on damp sheetrock. It may appear as a smudge of dirt, and can range in color from brown to black.

Stachybotrys

Commonly known as toxic black mold, this mold has achieved infamy in the media, and with good reason. Like chaetomium, stachybotrys requires live, active water intrusion to commence growth. Indoors, it is commonly found on wet materials containing cellulose, such as sheet rock, jute, wicker, straw baskets, and other paper materials. Unlike chaetomium, the symptoms produced by stachybotrys range beyond allergy-type symptoms to dermatitis, rhinitis, confusion, dizziness and disorientation, anxiety, depression, aggression, shaking, seizures, and an itching or burning sensation in the mouth, throat, nasal passages and eyes. It is known to produce severe brain fog, and mental impairment. As its common name implies, stachybotrys is black in appearance. (Please note that not all black mold is stachybotrys. There are many molds, some quite benign, that present with a black color. If you’re unsure, have a professional test your home.)

    It was interesting when you explained that Cladosporium mold can grow in both warm and cold areas. My husband and I noticed white-colored mold growing on the floorboards of our kitchen when we were cleaning yesterday morning. Thanks for helping me feel prepared to ask questions about the cause of the mold when were her a testing service to take a look!
