Can mould spore trap analysis detect mould before it is visible?

Yes, one of the key advantages of spore trap analysis is its ability to detect elevated airborne spores even when visible mould is not present. This is particularly useful in cases where occupants report odours or health symptoms, or when water damage is suspected but not obvious. Since mould often colonises within wall cavities, ceilings, or HVAC systems, airborne spores may escape into occupied spaces before surface growth becomes visible. Early detection allows for quicker response and minimises potential health impacts.
