What Makes Mold Dangerous
Mold is a visible coating produced by microscopic fungi. The mycelium grows deeper than what can be seen on the surface, so a simple wipe-down is never enough. The fungus needs air humidity of seventy to eighty percent for active development and temperatures between three and twenty-one degrees Celsius.
Black mold — Aspergillus niger — is the most dangerous variety. It colonizes wallpaper, painted concrete, and bathroom tile, feeding on organic contaminants as its nutrient base. Its continued presence provokes gradual health decline: allergies, breathing difficulty, skin rashes, and digestive problems. During mold remediation in San Diego, every colony and hidden spore reserve must be located before treatment begins.
