Different Types of Mold That Can Invade Your Home

There are several different types of mold that can invade your home and cause issues for you and your property. Learn about the types of mold with this guide.

According to one recent report, more than half of all U.S. households will experience a mold problem. Moreover, nearly 30% of people are highly susceptible to health issues linked to mold exposure.

As a diligent homeowner, you naturally want to keep your property as clean and sanitary as possible. As you vacuum, mop, and wipe down surfaces, have you considered the possibility of mold growth?

Knowledge is key to prevention, so today we're sharing a few of the most common types of mold that could appear in your home. The more you know, the quicker you can take action and safeguard your space for good. 

Aspergillus

Aspergillus is one of the most common kinds of mold found in homes. This is a mildly allergenic mold that can trigger respiratory distress when inhaled. 

Aspergillus most commonly grows within the damp and musty environment of an air conditioning unit. However, you may also find it on food. It can grow both indoors and outdoors and can reproduce rapidly near a water source. 

While some mold spores are visible to the naked eye, note that its roots can grow deeply into food or other surfaces. Aspergillus can appear fuzzy and gray in color. 

Alternaria

Like Aspergillus, Alternaria can also grow indoors and outdoors and prefers damp, cool spaces. It's most commonly found outdoors, on plants and wood.

In nature, this mold catalyzes the decomposition process. As a result, some agricultural researchers use it as a bio-control agent to prevent the spread of invasive pests and plant species. 

If spores from the outside make their way into your home, Alternaria will most commonly develop on the following surfaces and spaces:

  • Clothing
  • Carpets
  • Windows
  • Doors
  • Drywall
  • Plywood
  • Paint

The mold spore colonies can be black, green, or gray in color. You may also notice them in damp places around your home, such as under the sink or near the shower.

Aureobasidium

Have you noticed a slimy cream-colored or pink-tinged substance on certain surfaces in your home? If so, then it could be Aureobasidium. This is a common household mold that starts out light in appearance and later turns brown or black, developing a velvety texture over time. 

You're most likely to find Aureobasidium in moist environments, such as around your window frames or near your bathtub. It can also appear on the following surfaces:

  • Wooden furniture
  • Wallpaper
  • Painted walls
  • Tile grout
  • Textiles
  • HVAC units
  • Caulk

Physical reactions to Aureobasidium are common and can range from headaches and skin rashes to severe respiratory distress. 

Cladosporium

Cladosporium is primarily an outdoor mold. It grows on dead or decaying plants, as well as rotting organic matter. When the mold reaches maturity, it releases spores. 

These spores can become airborne and enter your home. Once inside, they can start to grow on:

  • Bathrooms
  • Carpets
  • Tiles
  • Wallpaper
  • Wooden or painted surfaces

If you've noticed a colony of mold comprised of small black dots that look like black pepper, then it could be Cladosporium. This mold can also trigger respiratory problems if left untreated.

Chaetomium

When a house experiences any type of flooding or a water leak, then there's the potential for Chaetomium to develop. Outdoors, this mold prefers the damp and moist habitat of the woods, where it develops in soil and on plant debris. 

In its early stages, it will appear fuzzy and white. As time goes by, it can darken in color and even resemble black mold. Around your home, look for it on any moist surface that contains cellulose, such as:

  • Wood
  • Drywall
  • Ceiling tiles

If there are any water-damaged surfaces in your home, then these could also harbor Chaetomium colonies.

Fusarium

Both houseplants  and humidifiers can improve the air quality inside of your home. Unfortunately, they can also have the opposite effect if they harbor dangerous mold spores. 

Fusarium is a type of mold that prefers these two spots. It can enter your home via an indoor plant, or the spores can simply travel through the air. It can also develop on old and outdated food. 

If the mold is left to form colonies, then you'll notice visible growth on surfaces throughout your home. A few places to check include:

  • Drywall
  • Behind wallpaper
  • Under carpets

Fusarium often spreads due to an increased moisture level within a home. For instance, it can occur after extensive water damage, or if humidity levels are too high. 

Penicillium

As you might have guessed, some spores within the Penicillium genus are used to make the antibiotic Penicillin. However, there are other spores that create a decidedly less helpful effect.

This mold can grow anywhere in your home where there's an adequate amount of moisture. In the kitchen, look for it on old produce, including spoiled fruits and vegetables, as well as outdated. It can also grow on rotting plant bulbs. 

The growths will be fuzzy in texture and can be either blue or green. You may also notice them on wooden surfaces throughout your home, as well as tiles. 

Stachybotrys

There are many different species of Stachybotrys mold. However, there are two particular ones that savvy homeowners need to know about:  Stachybotrys chartarum  and  stachybotrys chlorohalonata.

These strains are known as black mold. This is a toxic and dangerous type of mold that can lead to significant health issues. Often, they develop when indoor air is filled with too much moisture. When this is the case, Stachybotrys can develop and spread through a home's ventilation system.

If you believe you have any instances of Stachybotrys in your home, then it's important to hire a licensed remediation specialist  to correct the issue. This step should be part of a more comprehensive effort to lower the amount of moisture in your home to a safe level.

While these are a few of the most common types of mold that can occur in your home, this list isn't exhaustive. That's why it's helpful to partner with a mold remediation company that can help you spot, treat, and prevent any type of dangerous growth from occurring.
