Trichoderma species in West Virginia homes
The aggressive green colonizer of soaked wood
What this species signals about a building
Trichoderma is a fast, aggressive colonizer of very wet cellulose, common in flood aftermath and chronically wet crawl spaces. Some species are notable for degrading wood and even attacking other fungi — a sign of a mature, wet microbial ecosystem.
Where West Virginia buildings feed it
Humid continental mountain climate. Hillside construction concentrates water at uphill foundation walls; drainage correction anchors many fixes.
Read those two paragraphs together and the assessment map draws itself: this organism grows where its moisture requirement is met, and West Virginia's climate and housing stock determine where that requirement gets met most often. That intersection — not a generic national checklist — is where instruments should go first.
What remediation requires
Locate the saturation zone — crawl spaces and post-flood assemblies lead the list — remove colonized materials, dry the structure with verification, and address the bulk-water pathway that created the conditions.
Fast-spreading colonies that begin white and turn vivid green as spores mature, often with a coconut-like odor.
- Hillside drainage against foundations
- Damp basements
- High rainfall
West Virginia questions
Where does Trichoderma species typically show up in West Virginia homes?
The organism's requirements don't change by state — it grows where its moisture threshold is met. What changes is where West Virginia buildings meet that threshold: hillside drainage against foundations Combined with the local housing stock (hillside construction concentrates water at uphill foundation walls; drainage correction anchors many fixes), that's where an assessment should look first.
Does finding Trichoderma species mean something different in WV?
Trichoderma viride appears among the HERTSMI-2 marker species. Its presence in dust at meaningful levels indicates genuinely wet building materials somewhere in the envelope and belongs in the investigate-seriously category. In West Virginia, weigh that signal against the state's dominant moisture drivers — the species tells you about the water, and the local climate tells you where that water most likely came from.
Who handles Trichoderma species contamination in West Virginia?
Remediation requirements are set by the contamination, not the species name: locate the saturation zone — crawl spaces and post-flood assemblies lead the list — remove colonized materials, dry the structure with verification, and address the bulk-water pathway that created the conditions. We match West Virginia households with providers vetted on containment discipline, fine-particle competence, and independent verification — matching is free for households.
