Could this hidden mold cause my kids' coughing?« Back to Previous Page

Yes, this hidden mold is a very likely cause of your children's persistent coughing. The black patch you found is a significant indicator of a long-term moisture issue, and the confined space behind the wardrobe allowed airborne spores to accumulate before circulating in the bedroom's air. In Dubai's climate, where high humidity and constant AC use create perfect conditions for mold, such hidden growth is a common trigger for respiratory irritation, allergic reactions, and asthma-like symptoms, especially in children.

The proper cleaning process is critical. For a patch you describe as "huge," a professional inspection and remediation is strongly advised. Simply wiping it with bleach is ineffective and can aerosolize spores, making the problem worse. Professionals will first identify and fix the AC leak—the moisture source—as mandated by Dubai regulations for any remediation work. They will then contain the area, safely remove the contaminated materials, and use HEPA filtration to clean the air. After removal, a post-remediation verification test, ideally from an independent lab, is the only way to confirm the spore count in the room has returned to a safe level. This scientific verification is key to ensuring your family's health is protected.
