Could mold on toy chest cause my kids' coughs?« Back to Previous Page

My kids have been coughing at night for the past few weeks and I'm starting to worry. I finally pulled out their wooden toy chest from the corner of their bedroom in our villa in Jumeirah and found a bunch of black, fuzzy spots on the back where it was against the wall. We had that unexpected heavy dew a while back and the room felt damp for days. Could this mold be the reason for their coughs and what's the safest way to clean it with them in the house?

Based on your description, it is highly probable that the mold growth on the toy chest is a contributing factor to your children's persistent nighttime coughs. The black, fuzzy spots you describe are characteristic of a mold colony, likely of the Stachybotrys or Aspergillus genus, both of which are known to produce mycotoxins and volatile organic compounds (VOCs) that are respiratory irritants. Children are particularly susceptible due to their developing respiratory systems and higher breathing rates relative to their body size.

The conditions in your Jumeirah villa are a classic catalyst for such growth. The recent heavy dew significantly elevated the ambient humidity. When this moist air contacts cooler surfaces, such as an exterior wall cooled by year-round AC, it leads to condensation. This created a persistent damp microenvironment behind the chest, providing the perfect conditions for mold to proliferate on the organic material of the wooden toy chest.

For a small, localized surface growth on a non-porous item, cleaning with a diluted detergent solution can be effective. However, for porous materials like wood, the hyphae (root structures) penetrate deep into the material, making surface cleaning insufficient and potentially dispersing spores. Given that this is in your children's bedroom and is already affecting their health, the safest course of action is professional remediation.

We strongly recommend a certified mold inspection to assess the full extent of the contamination, including the wall behind the chest which is likely also affected. DIY attempts can inadvertently cross-contaminate other areas of your home. Our teams at Saniservice are trained in UAE-specific protocols and use industrial-grade HEPA filtration and antimicrobial treatments to safely remove the bio-contaminant, ensuring the health of your family is protected.
