Does Bleach Kill Black Mold
The EPA does not recommend using bleach to kill or remove mold, except in special circumstances. In fact, recognizing the bleach as a threat, the mold will grow back even stronger. When bleach is used on porous surfaces like drywall or wood, mold membranes will move deeper into the surface to avoid the chemical.
Types Of Mold Categorized By Health Effects
How Many Types Of Mold And Fungi Are There
There are over 100,000 different types of mold. Not all types of mold are a threat, however. Some types of mold are fairly benign, and some even have medicinal uses. For example, Penicillium is used in the production of penicillin, an antibiotic commonly prescribed to cure strep throat, bronchitis and other forms of infection.
The problem with there being so many species of mold is that differentiating toxic molds from household molds is nearly impossible for an untrained professional. If you discover mold growth in your home, you should call a professional mold removal company to inspect the area and determine if your home requires treatment.

Trying to buy or sell a house with black toxic mold can lead to major financial issues. Steve Levy explains how mold can develop into such a large problem : Mold spores comprise 25% of the worlds biomass. Generally mold in the outdoor environment is good because its what helps biodegrade waste. However, mold in the indoor environment can be hazardous to health if left untreated. Mold infestations may be hidden in places such as vents, wall cavities, even under floors and carpeting. With water being the key ingredient for mold to grow, the extent of any water damage should not be overlooked or ignored. Surprisingly, homes built over the last thirty to forty years may be more susceptible to mold growth due to the building materials used. Also, most newer homes dont allow for the proper air ventilation which causes moisture. Retention of moisture stimulates present dormant mold spores leading to mold growth.
Business/House Mold SymptomsKnowing Symptoms of Mold in the House or Workplace
Allergic Reactions Asthma Attacks Irritant Effects
Allergic reactions to mold are common and can be immediate or delayed. Repeated or single exposure to mold, mold spores, or mold fragments may cause non-sensitive individuals to become sensitive to mold, and repeated exposure has the potential to increase sensitivity. Allergic responses include hay fever-like symptoms such as:
- Allergic reactions
- Aggravated asthma symptoms
These and other symptoms may be associated with exposure to mold. But all of these symptoms may be caused by other exposures or conditions unrelated to mold growth. Therefore, it is important not to assume that, whenever any of these symptoms occurs, mold is the cause.

Moisture Control Is The Key To Mold Control
Mold does not need a lot of water to grow. A little condensation, in a bathroom or around a window sill, for example, can be enough. Common sites for indoor mold growth include:
- Bathroom tile and grout
- Plant material
In most cases, temperature is not an issue some molds grow in warm areas, while others prefer cool locations such as bread stored in a refrigerator. Often, more than one type of mold can be found growing in the same area, although conditions such as moisture, light and temperature may favor one species of mold over another.
Buildings that have been heavily damaged by flood waters should be assessed for structural integrity and remediated by experienced professionals. Please note that the guidelines covered in this course were developed for damage caused by clean water .

It has long been postulated that exposure to damp, moldy home and workplace environments has detrimental health effects. At the beginning of the 18th century, Ramazzini, considered the father of occupational medicine, described an illness of workers inhaling foul and mischievous powder’ from handling crops . More recently, Platt et al. , found that occupants of wet, moldy buildings had an increase in subjective complaints. Brunekreef et al. found a similar pattern in > 6,000 children in six states in the United States and reported home dampness was a strong predictor of respiratory and other illness in this age group. The list of putative symptoms generally consists of upper respiratory complaints, including headache, eye irritation, epistaxis, nasal and sinus congestion, cough, cold and flu symptoms, as well as generalized gastrointestinal complaints . Taskinen et al. reported an increased prevalence of asthma in moisture-affected schools, although there were no objective measurements of respiratory disease. A number of studies have reported a relationship between similar symptoms and damp housing or workplace environments, although the proposed etiologies have varied .
The indoor environment also contains a wide range of microorganisms including bacteria , mycobacteria , and molds , as well as their products, including endotoxins and mycotoxins. There may often be a much higher bacterial load than fungal load .

Understanding Types Of Mold
Mold is a broad term that describes a range of micro-organisms that grow in the presence of a food source and usually require sufficient moisture. More specifically, mold is a type of fungi, and growths are sometimes generically called mildew. Mold usually falls into one of three broad categories.
Allergenic molds are not toxic in and of themselves, but can trigger allergic reactions such as asthma.
Pathogenic molds can trigger illnesses in people already weakened by other causes.
Toxigenic families of molds are the most dangerous because they create their own toxins that can lead to health problems that are sometimes lethal.
Fortunately, regardless of the type of mold youve got, it can be killed with a registered fungicide.
Read on to learn more about the different types of molds and how to recognize them.
Type of Mold: Allergenic.
Where Its Found: Bathrooms and damp windows.
Got moldy stuff growing in your bathroom or shower? Perhaps mold along the bottom of windows where condensation develops during cold weather? Its probably a mold called Alternaria. This is the most common type of allergenic mold.
From the genus ascomycete, this organism thrives around the globe outdoors in natural ecosystems. But Alternaria can cause problems when it ventures indoors. It causes allergic reactions in people, and can also trigger hypersensitive conditions such as hay fever and asthma. This organism can infect people whose immune systems are impeded.
Type of Mold: Allergenic.
What Types Of Mold Are Considered Toxic Mold
Toxic mold is a term that is used to describe types of mold that are considered deadly to humans. Most people believe that the name refers to one particular species of mold however, it encompasses hundreds of species, a small fraction of which are not very harmful to the human body. Black mold is commonly used as a name for the most harmful mold species, which happen to be black in appearance. However, even molds of a different color can be toxic to the human body.
Any place that is dark and where there is an accumulation of moisture, is a potential breeding pool for mold. Mold can grown on almost any organic surface as long as moisture and oxygen are present. When large amounts of moisture build-up in buildings, or building materials mold growth will occur. It is virtually impossible to remove all indoor mold and mold spores, but it is possible to manage.
People are exposed to some amount of mold everyday. When mold is growing on a surface, spores can be released into the air where a person can then inhale them. A person who is subject to inhaling a large amount of these spores may be subject to some medical damage.

Common Types Of Mold Found In Homes
Alternaria is often found outdoors, but it also grows in damp places indoors, like in showers or under sinks with leaky pipes. It can also be found in buildings that have been flooded or suffered other water damage. It spreads easily from one area of the home to another. Exposure to alternaria can cause allergic reactions and asthma attacks.
Aspergillus is a type of mold frequently found indoors. It can causes allergic reactions, respiratory infections, and a condition called hypersensitivity pneumonitis, which causes inflammation of the lungs. More about aspergillus mold.
Aureobasidium is a mold often found outdoors, but it can also be found in homes growing on wooden surfaces, wallpaper, and painted surfaces. Its also often found on damp window frames and caulking. It is pink and black in color. Many people are allergic to aureobasidium. Follow the link for more information on pink mold in the bathroom.
Botrytis grows in areas with high levels of humidity, like bathrooms with poor ventilation. It can cause allergic reactions and asthma.
Chaetomium often grows on drywall, carpets and window frames that have sustained water damage. It produces a characteristic musty odor.
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.
How Do You Get The Molds Out Of Buildings Including Homes Schools And Places Of Employment
Mold growing in homes and buildings indicates that there is a problem with water or moisture. This is the first problem to address.
Remove moldy items from living areas. Once mold starts to grow in carpet, insulation, ceiling tiles, drywall, or wallboard, the only way to deal with the problem is by removal and replacement.
It is important to properly clean and dry the area as you can still have an allergic reaction to parts of the dead mold and mold contamination may recur if there is still a source of moisture.
Remove or replace carpets and upholstery that have been soaked and cannot be dried promptly.
Clean up and dry out your home thoroughly and quickly after any flooding. Dig out mud and dirt . Use a wet vacuum to remove remaining dirt. Scrub cleanable surfaces with soapy water and a bristle brush. Thoroughly clean all hard surfaces with water and dish detergent. Dry surfaces quickly and thoroughly after cleaning. If you have a fan, air conditioner or dehumidifier that wasnt affected by flooding use it to help the surfaces dry after you finish cleaning
Mold growth can be removed from hard surfaces with commercial products, soap and water, or a bleach solution of no more than 1 cup of bleach in 1 gallon of water to kill mold on surfaces. Never mix bleach with ammonia or other household cleaners.
