Here are four of the most common types of mold: <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li style=\"line-height:1.7\"><strong>Black Mold (stachybotrys chartarum<\/strong>) \u2013 This allergenic, black pepper-like microorganism is<strong> most prevalent in wood, wallpaper, and leaky ceiling <\/strong>surfaces. It has a strong musty odor, often hidden behind walls.<\/li>\n\n\n\n<li style=\"line-height:1.7\"><strong>Aspergillus <\/strong> \u2013 A very common fungal spore that <a href=\"https:\/\/www.cdc.gov\/fungal\/diseases\/aspergillosis\/index.html\"><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-ast-global-color-7-color\">causes aspergillosis<\/mark><\/a>, a respiratory infection. <strong>This fungus may start white before turning green or gray with a powdery texture<\/strong>. Usually grows on walls and fabrics.<\/li>\n\n\n\n<li style=\"line-height:1.7\"><strong>Cladosporium <\/strong>\u2013 With at least 500 species, identifying this allergenic microorganism can be challenging. <strong>Their appearance is usually brownish or greenish with a velvety-like texture.<\/strong> It often grows in circular patches on carpets, upholstery, and under sinks.<\/li>\n\n\n\n<li style=\"line-height:1.7\"><strong>Penicillium<\/strong> &#8211; We owe a lot to this mold, which shares its name with the antibiotic. <strong>It has a plush texture that\u2019s blue-green in color and usually grows on aged fruit and veg<\/strong>, but also water water-damaged structures. Spreads quickly and it\u2019ll cause a flare-up in respiratory problems like asthma.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_do_you_detect_mold_in_your_house\"><\/span><strong>How do you detect mold in your house<\/strong>?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Although most homeowners leave mold detection and removal to professionals, they recognize the<strong> importance of testing for the presence of mold and mildew<\/strong>.&nbsp;That way, it\u2019s easier to tell if the mold requires a professional to successfully remove it.<\/p>\n\n\n\n<p class=\"has-link-color wp-elements-c47bebe38fbbff41470c68c39bbd43c3\">It is important to notice that the <a href=\"https:\/\/www.cdc.gov\/mold\/faqs.htm\" target=\"_blank\" rel=\"noreferrer noopener\">US Centers for Disease Control and Prevention<\/a> doesn\u2019t recommend mold testing or sampling, they suggest immediate removal of any type of mold that occurs.&nbsp;<strong>Here\u2019s how to test for mold in your home.&nbsp;<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Make a home mold test kit<\/h3>\n\n\n\n<p>To make a mold test kit at home, you will need to do a diluted bleach test on the suspected mold.<strong> Combine 16 tablespoons of water and a tablespoon of bleach to make a home mold test kit.<\/strong> Get a cotton swab, dip it into the bleach-water solution, and dab it on suspected mold-infested sections.<\/p>\n\n\n\n<p><strong>Assume the presence of mold if the area changes color immediately after dabbing it with diluted bleach. <\/strong>Alternatively, the area returns to its original color (black or greenish-black) after blotting. This method isn\u2019t as sophisticated as professional mold testing. However, it <strong>gives you a heads-up whether you have a mold infestation in your home.<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Buy a mold detection test<\/h3>\n\n\n\n<p>If unsure about the results of the DIY home mold test kit, purchase a black mold test package. <strong>Mold and mildew testing packages come in two forms: test-only and test-with-species-identification.&nbsp;<\/strong>The former is cheaper and only serves to confirm mold presence in the home. Testing kits with species identification are suitable for those curious about the specific mold.<\/p>\n\n\n\n<p>When mold isn\u2019t obvious, testing can be useful to determine if it is present. However, <strong>a faster means of gauging if mold is present is to simply listen to the body<\/strong>. Feeling unwell? <strong>Check out the 10 most common symptoms of black mold.<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<div class=\"ast-oembed-container\" style=\"height: 100%;\"><iframe loading=\"lazy\" title=\"Mold Testing Made Easy at Home with Simple Steps\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/ecpe463Byrc?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/div>\n<\/div><figcaption class=\"wp-element-caption\">Credit: Crawl Space Ninja<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">3. Follow the mold testing kit instructions<\/h3>\n\n\n\n<p><strong>Mold detection kits include step-by-step instructions on growing a suitable medium for promoting mold growth. <\/strong>We recommend reading this to get accurate results. Most testing packages come with Petri dishes and other tools for collecting and managing the sample.&nbsp;<\/p>\n\n\n\n<p>The specimen collection depends on what part of the house you want to test for mold. Leave the Petri dish for as long as instructed, then cover it to grow the mold.&nbsp;This method is perfect for checking mold in ventilation systems and similar technologies that aren\u2019t easily accessed, or if you\u2019re unsure about mold being present at all.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Assess the test for mold infestation<\/h3>\n\n\n\n<p class=\"has-link-color wp-elements-18ed2892440275af79969fea127fde31\">The <a href=\"https:\/\/www.fema.gov\/pdf\/rebuild\/recover\/fema_mold_brochure_english.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">Federal Emergency Management Agency<\/a> (FEMA) says <strong>mold and mildew need 24 to 48 hours to develop after moisture exposure<\/strong>.&nbsp;Check the Petri dish after 48 hours or as instructed for the telltale signs of mold. <\/p>\n\n\n\n<p class=\"has-link-color wp-elements-314457ff30a6c436de03e84de021910e\">Assess the sample again after another 24 hours if you didn\u2019t see mold signs in the first 48 hours. If the instant mold test produces negative results, it\u2019s safe to say there\u2019s no mold.<\/p>\n\n\n\n<p>A mold test kit can help determine if your home has a mold problem, and how severe it is. <strong>They don\u2019t replace professional lab analysis, but they\u2019re useful for initial mold detection.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_are_the_Most_Common_Places_to_Find_Mold_in_a_Home\"><\/span><strong>What are the Most Common Places to Find Mold in a Home?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"has-link-color wp-elements-85bc8fbb66bc485f9a2bb0e0f47f1a11\">The <a href=\"https:\/\/www.cdc.gov\/mold\/faqs.htm\" target=\"_blank\" rel=\"noreferrer noopener\">US Centers for Disease Control and Prevention<\/a> says <strong>mold grows in high-moisture areas, <\/strong>including plumbing, around windows, and on roofs.
