class=\"ez-toc-section-end\"><\/span><\/h2>\n<p data-start=\"606\" data-end=\"810\">Mold stains walls, produces strong odors, and makes indoor spaces uncomfortable. The moment it appears, many homeowners reach for bleach or chemical sprays, assuming the problem can be wiped away quickly.<\/p>\n<p data-start=\"812\" data-end=\"865\">That approach creates a dangerous illusion of safety.<\/p>\n<p data-start=\"867\" data-end=\"1029\">Spraying mold does not remove it. In many cases, it makes the situation worse by disturbing spores, masking deeper contamination, and delaying proper remediation.<\/p>\n<p data-start=\"1031\" data-end=\"1098\">Understanding how mold behaves explains why surface spraying fails.<\/p>\n<hr data-start=\"1100\" data-end=\"1103\" \/>\n<h2 data-start=\"1105\" data-end=\"1159\"><span class=\"ez-toc-section\" id=\"What-Mold-Really-Is-and-Why-It-Is-Hard-to-Eliminate\"><\/span>What Mold Really Is and Why It Is Hard to Eliminate<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p data-start=\"1161\" data-end=\"1228\">Mold is a type of fungus. It is not dirt, dust, or a surface stain.<\/p>\n<p data-start=\"1230\" data-end=\"1299\">Mold grows by extending microscopic filaments into materials such as:<\/p>\n<ul data-start=\"1300\" data-end=\"1380\">\n<li data-start=\"1300\" data-end=\"1311\">\n<p data-start=\"1302\" data-end=\"1311\">Drywall<\/p>\n<\/li>\n<li data-start=\"1312\" data-end=\"1328\">\n<p data-start=\"1314\" data-end=\"1328\">Wood framing<\/p>\n<\/li>\n<li data-start=\"1329\" data-end=\"1347\">\n<p data-start=\"1331\" data-end=\"1347\">Carpet backing<\/p>\n<\/li>\n<li data-start=\"1348\" data-end=\"1362\">\n<p data-start=\"1350\" data-end=\"1362\">Insulation<\/p>\n<\/li>\n<li data-start=\"1363\" data-end=\"1380\">\n<p data-start=\"1365\" data-end=\"1380\">Ceiling tiles<\/p>\n<\/li>\n<\/ul>\n<p data-start=\"1382\" data-end=\"1542\">The visible growth on a wall or floor is only a small part of the organism.
