The sooner you discover any mold problems in your attic, the higher the possibility that it can be controlled.
Types of Mold Found in the Attic
There are many different types of molds that can be present in your attic. Scientists don’t actually know how many molds exist. Some believe it could be one hundred thousand or more.
Mold is a type of fungus. Generally, you can split the mold types into two categories: toxic attic mold, and non-toxic attic mold. We recommend that the toxic molds be dealt with quickly and with the help of professionals. On the other hand, while non-toxic mold is less less threatening, it should still be examined and cleaned up as well.
Harmful molds can be broken down into three different categories: allergenic, pathogenic and toxigenic. Allergenic mold are those that causes allergic reactions from people when inhaled or made contact with. The pathogenic kind, are those that may cause more serious symptoms such as nausea, headaches and other respiratory illness. Lastly, molds categorized as toxigenic are very hazardous and may lead to death.
Here are some of the toxic molds that can be in your attic:
Acremonium and Fusarium are toxigenic types of mold that appears as a fine powdery substance. While Chaetomium and Stachybotrys are pathogenic mold. Stachybotrys chartarum is a common type of black mold
Although there are a number of threatening molds, most often than not, what homeowners find in their attic are of the non-toxic kind. Here are some of the common non-toxic molds found in the attic:
Aspergillus mold is a common one that may be hard to spot. Other common types include Aspergillus versicolor, Aspergillus and Penicillium. Alternaria, aspergillus, Trichoderma, Ulocladium, Aureobasidium, Mucor and Cladosporium are common forms of allergenic mold.
Although these molds are relatively less harmful to your health, they still need to be dealt with as they can still damage your home.
