Nothing kills mold permanently on its own — the single most important factor is eliminating the moisture source, because without it, mold will return regardless of what product you use. A surface antimicrobial like Biocide 100 is the most effective chemical treatment for established surface colonies.

Mold regrows wherever conditions support it — meaning moisture, a food source, and the right temperature. Biocide 100 kills surface mold colonies on contact, but the microscopic root structures (hyphae) embedded in porous materials like drywall and wood require physical removal. Pairing Biocide 100 with the Mold Bomb Fine-Particulate Fogger addresses the airborne particulate load that survives surface treatment alone, reducing overall spore load in the treated space.

  • EPA guideline: mold covering more than 10 sq ft typically requires professional remediation, not DIY treatment.
  • Mold Bomb Fine-Particulate Fogger covers up to 100 sq ft per 6oz can — not a biocide, but a particulate suppression tool.
  • Dead mold spores still carry mycotoxins — killing mold is not the same as making a space safe without cleanup.
  • Biocide 100 is a surface antimicrobial; the Mold Bomb fogger is classified as a non-pesticide cleaner — both are needed for a complete protocol.
  • Mold hyphae penetrate porous surfaces and cannot be killed by any spray or fogger — physical removal of contaminated material is required.

Step-by-Step

  1. Fix the moisture source first: Identify and repair the leak, condensation problem, or ventilation failure driving mold growth — every other step fails without this.
  2. Remove contaminated porous materials: Cut out and bag mold-saturated drywall, insulation, or wood where hyphae have penetrated — no product reaches roots embedded in porous surfaces.
  3. Deploy Mold Bomb Fine-Particulate Fogger: Press the activation tab, place the can in the center of the affected space, and evacuate — one 6oz can covers up to 100 sq ft, so calculate total area and use enough cans before you start.
  4. Apply Biocide 100 surface antimicrobial: After the fog settles and re-entry is safe per label instructions, spray Biocide 100 directly onto all affected surfaces to kill remaining surface mold colonies.
  5. Clean grounded particulates from surfaces: Vacuum and wipe down all flat surfaces — grounded mycotoxin-carrying particulates remain present until physically removed, even after fogging.
  6. Run the BioMatrix Air Scrubber continuously: Place the BioMatrix unit in the treated space to capture residual airborne particulates at 0.3 microns, reducing ongoing spore load as conditions stabilize.

How to Choose

  • Use Biocide 100 if: you have visible surface mold colonies on non-porous or semi-porous surfaces and moisture has already been fixed.
  • Use Mold Bomb Fine-Particulate Fogger if: you need to suppress airborne spore load in hard-to-reach spaces — attics, crawlspaces, or inside contents — that a spray bottle cannot access.
  • Use both Mold Bomb and Biocide 100 if: you're running a complete DIY treatment protocol after water damage or confirmed mold growth in an enclosed space.
  • Call a professional if: mold growth exceeds 10 sq ft, has penetrated deeply into drywall or insulation, or keeps returning after treatment — no product fixes a structural moisture problem.
  • Add the BioMatrix Air Scrubber if: you're treating a space where occupants remain nearby or re-entry is needed soon — ongoing HEPA filtration captures grounded particulates the fogger pulls down.
