Mould Mites in Singapore — Identification, Removal & Prevention

Mould mites are microscopic arachnids — typically Tyrophagus putrescentiae — about 0.3–0.5 mm long, pale white to tan. To the naked eye they look like fine, slowly-moving dust on a mouldy surface. Under a magnifying glass they appear as tiny eight-legged creatures.

The mites themselves don't bite humans and rarely cause serious harm. The bigger concern is the mould colony feeding them — mould spores trigger respiratory irritation, allergies and asthma flare-ups. People allergic to dust mites may also react to mould-mite proteins.

Dust mites feed on shed human skin in bedding and carpets and prefer 70–80% humidity. Mould mites feed on actual fungal growth and only appear where mould is active. If you see 'dust' moving on a damp wall or ceiling, it's almost certainly mould mites, not dust mites.

Yes — without their food source, mould mites die off within days. Our treatment removes both the visible mould and the substrate moisture that sustains the colony. vacuuming captures residual mite bodies before sealing.

DIY surface sprays kill visible mites but rarely reach the mould inside porous surfaces or behind paint. Without addressing the moisture source, mites return within weeks. Professional treatment is the only way to break the cycle.

Keep relative humidity below 65% (ideally 50–60%), fix any active leaks, run an exhaust fan during and after showers, and have mould-resistant paint applied to chronic problem areas — bathrooms and toilets through our Toilet Refresh ($199) or Toilet Protection Pro ($400) packages, other areas through Essential or Signature Care.
