Is black mold behind boxes causing my kids' cough?« Back to Previous Page

That black mold discovery is absolutely the environmental factor your pediatrician is asking about. In Dubai's climate, the constant AC use creates significant temperature differences between cooled rooms and unconditioned spaces like storage closets, leading to condensation and mold growth on walls. The mold behind the boxes is releasing spores into the air, which are then circulated by your home's AC system, likely irritating your children's respiratory systems and causing that persistent cough.

For your family's safety, the first step is to isolate the area. Keep the closet door closed and limit access, especially for the children. Do not attempt to clean it yourself with bleach, as disturbing it will aerosolize more spores. The urgency is high to identify the extent and type of mold, as some species common here can produce mycotoxins.

You need a professional inspection. A certified inspector will use moisture meters and borescopes to check inside the wall cavity for hidden growth, which is very common in such scenarios. The most critical step is lab analysis of a tape lift or air sample to identify the species. This tells you the actual health risk and dictates the correct remediation protocol, which is not a one-size-fits-all process.

For remediation, the wall will likely need to be opened, the affected materials properly removed, and the area treated with specialized antimicrobials. A HEPA air scrubber is essential during this process to contain spores. Finally, the source of the moisture—likely condensation from the temperature differential—must be addressed with better insulation or ventilation to prevent it from returning. Given the health symptoms, treating this with professional seriousness is the fastest way to restore your indoor air quality and your children's health.
