Types of Mold That Are Blue

While there is no such thing as a species of mold specifically called “blue mold”, there are many types of mold that can appear blue. One of the most common types of mold that appears blue is Penicillium. Penicillium strains are found both indoors and outdoors, and some strains of Penicillium are used to create antibiotics and cheese. That being said, there are other strains of penicillium that are toxic because they produce significant amounts of mycotoxins. If you are not sure which species of mold is present in your property, we recommend that you call (855) 460–0914 to speak with a mold professional anywhere in the United States about it right away. If the mold is the toxic kind, it may not be ideal for you, your family, and/or your pets to be near it.

Where Does Mold Commonly Grow?

While mold is commonly found in a wide variety of places in buildings, it is commonly found wherever moisture is available. For this reason blue mold on walls in bathrooms is quite common due to the bathroom being a common place where moisture is present.

How to Check for Mold

Mold may not always be in plain site, so it is important that you know how to check for it in your property. We recommend using a moisture meter and/or looking for water stains in your property to see if there is any water damage. As stated before, mold needs moisture to grow so if you find a moisture source, that is a sign that there may be mold present also. Another way to check for mold is by using a mold testing kit. While these are not always accurate, they are a good thing to try.

Blue Mold on Food

While blue mold is actually common in certain foods like blue cheese, it is not safe on other types of foods where it is not supposed to be found. One example of a type of food you should avoid if it has any sort of mold contamination is on bread. This is because the blue mold strain found on the bread can be a toxic one without you knowing.

How to Remove/Remediate Blue Mold

While it is possible to remediate a small amount of mold yourself, we recommend at least consulting with a professional before attempting it. If you remediate the mold incorrectly, it can grow back and/or cause mold spores to go airborne in your property.

Here is the mold remediation process that is commonly preformed by experts:

Step 1: Where Safety Gear

We recommend putting on respirator masks, and potentially also a full-body hazmat suit before attempting to remediate mold. One reason for this is because mold spores can go airborne during the mold mitigation process, so you don’t want to be breathing them in.

Step 2: Take Care of Your Personal Belongings

Mold can contaminate your personal belongings, so it is important that you remove them, clean them with an antimicrobial agent, and/or dispose of any affected materials before remediating the mold. Failure to do this could cause the mold to grow back because it is still in your personal belongings. Keep in mind that porous materials like clothing are more susceptible to mold growth than solid materials like glass.

Step 3: Set up a Barrier

We recommend using polyethylene sheeting to create a temporary enclosed area around the mold affected areas of your property. This is done primarily to prevent the spread of mold during the remediation process. within this barrier we also recommend that you run some HEPA filters to catch mold spores and other toxins during the remediation process.

Step 4: Fix Leaks and Dry the Water Damage

Mitigating the mold without drying the moisture that caused it in the first place will likely cause it to grow back. If there is a leak in your property, we recommend fixing it and using specially water damage restoration fans and dehumidifiers to dry the affected areas. If the damage is severe, you will need to demolish the area which we will discuss in the next step.

Step 5: Demolish the Contaminated Area

While it is possibly to simply spray some antimicrobial solution on the mold and hope it goes away, that doesn’t always work. We recommend going the safe route by demolishing mold damaged areas.

Step 6: Cleaning and Sanitization

In this step you will clean and sanitize any remaining mold residue using wire brushes and an antimicrobial solution.

Step 7: Reconstruction

You probably don’t want to live in a property with demolished walls for example, so you will need to install new building materials. When doing this you may want to consider building materials that are at least somewhat waterproof to avoid future water damage and mold growth.

Step 8: Put Back Personal Belongings

In this step you will put back the personal belongs that you cleaned and sanitized in step 2. Be careful not to put back any personal belongings that are still contaminated with mold as this can cause the mold to grow back. It’s probably better to be safe than sorry when deciding which personal belongings to keep. Don’t be afraid to dispose of the belongings you are not sure about.
