Mold Treatment Guide
Significant Mold Treatment
When mold has affected more than one room, or has been detected with mold tests and is present but not seen, fogging with HavenFog™ will reduce mold and keep it under control. Each HavenFog Kit includes HavenFog, and a HavenFogger (large or mini, depending on the size of the environment) and plates for testing before and after your treatment.
This protocol was developed and validated by Jeff Bookout (CMI, CMRC, AHERA Inspector — 20+ years, 4,000+ mold assessments) and JW Biava (CMI, CMRC, ISEAI Board Member — 100,000+ inspections). HavenFog™ is formulated by Walter Hayhurst, RPh, PCCA using citrus seed extracts with a Material Safety Data Sheet (MSDS) of all zeros for all hazard categories. HavenFog™ disperses a fine citrus-based mist that remains airborne long enough to reach mold colonies on surfaces, behind walls, and inside HVAC ducts throughout the treatment area.
Significant Mold Treatment Steps
Choose one of the following kits:
HavenFog Kit
The HavenFog Kit includes a 1,500-watt thermal fogger, one gallon of HavenFog solution, and four mold test plates. The included solution treats up to 4,000 square feet. Applying HavenFog throughout a 3,000-square-foot area takes approximately two hours. This estimate covers application only; preparation, waiting, and small particle cleanup are separate steps.
HavenFog Mini Kit
The HavenFog Mini Kit includes a 1,100-watt thermal fogger, one quart of HavenFog solution, and two mold test plates. The included solution treats up to 1,000 square feet. Application in a 1,000-square-foot area takes approximately one hour, excluding preparation, waiting, and small particle cleanup. Use HavenFog solution in either fogger.
1. Rip, Remove, Replace
Rip, remove, replace materials contaminated with visible mold. Use proper conditions (i.e. negative air containment, proper personal protective equipment or PPE, etc.) for your own safety and health. Call our experts at (505) 400-8891 for any guidance needed.
*May require professional remediation.
2. Test
Sample the area with a mold test. Collect air samples of the areas you will fog. After fogging you will test again and compare the results.
*Additional plates can be purchased at immunolytics.com. Visit immunolytics.com/analysis for steps on self-analyzing and interpreting your test.
3. Prep
Prep the area you are treating. Open all cabinets, drawers, closets, etc. for a thorough treatment of the area.
Allow up to one hour for preparation, depending on how and where you will apply the fog.
Disconnect all fire alarms. The fog will cause the alarms to sound.
4. Fog
HavenFog is intended as a one-time treatment. Additional treatment may be needed if a significant mold problem has not yet been remediated or after another water event. Use HavenMist for continued maintenance.
Fog your environment. Add HavenFog to your fogger and thoroughly treat the entire area.
Application takes approximately two hours for a 3,000-square-foot area with the HavenFog Kit, or approximately one hour for a 1,000-square-foot area with the Mini Kit. These estimates cover application only.
People and pets should not remain in the treatment area for extended periods during fogging. It is best to leave the fog undisturbed for 24 hours after fogging is finished. Re-entry after 12 hours is acceptable. Ventilate the treated areas when people or pets return.
Begin small particle cleanup 24 hours after fogging is finished. Cleanup time depends on the area to be cleaned and the thoroughness of the process.
People and pets may remain in the area throughout HavenMist misting. After misting, we recommend small particle cleanup by wiping or HEPA vacuuming. Cleanup may begin immediately after misting or at any later time.
After 24 hours clean all horizontal surfaces by HEPA vacuuming or wet wiping.
Optional
Shampoo with HavenClean all carpets, rugs, and fabric furniture before fogging.
5. Re-Test
Test for mold after 3 days. After treatment, wait at least 3 days and retest the areas with the included mold plates. Compare the new sample to the previous sample and to the ImmunoLytics health scale* to confirm the treatment was successful. You can use the included plates for self-testing. Optional laboratory analysis by ImmunoLytics is available for an additional fee and is not included in the kit price.
*Visit immunolytics.com/analysis for steps on self-analyzing and interpreting your test.
Optional
Mist your environment as often as needed. To maintain your environment and prevent mold growth, mist. Determine whether your environment needs to be misted again by mold plate testing or if health symptoms return.
Frequently Asked Questions
How is significant mold treatment different from isolated mold treatment?
Isolated mold treatment uses HavenMist™ and is appropriate when mold is confined to one or two rooms. Significant mold treatment uses HavenFog™ — a whole-room fogging system — when mold has spread to multiple rooms, is detected in air samples but not visible, or requires treatment of HVAC-connected spaces simultaneously.
Which HavenFog kit do I need?
The HavenFog Kit (1-gallon, large fogger) treats up to 4,000 sq. ft. and is recommended for whole-home treatment of homes up to 3,000 sq. ft., with solution left over for follow-up. The HavenFog Mini Kit (1-quart, mini fogger) treats up to 1,000 sq. ft. and is ideal for apartments, condos, or treating one to two large rooms.
Do I need to leave the house while fogging?
People and pets should not remain in the treatment area for extended periods during fogging. It is best to leave the fog undisturbed for 24 hours after fogging is finished. Re-entry after 12 hours is acceptable. Ventilate the treated areas when people or pets return.
How long does significant mold treatment take?
Application takes approximately two hours for a 3,000-square-foot area with the HavenFog Kit, or approximately one hour for a 1,000-square-foot area with the Mini Kit. These estimates cover application only. Allow up to one hour for preparation, depending on how and where you will apply the fog. Application time depends on the size of the area being treated. Begin small particle cleanup 24 hours after fogging is finished. Cleanup time depends on the area to be cleaned and the thoroughness of the process. The treatment guide walks you through preparation, application, waiting, and cleanup as separate steps. Follow the guide’s separate re-testing step.
Why do I need to test before and after treatment?
Pre-treatment mold plate testing establishes a baseline spore count for the areas you fog. Post-treatment testing (at least 3 days after fogging) confirms the reduction. The included plates can be used for self-testing. Optional laboratory analysis by ImmunoLytics is available for an additional fee and is not included in the kit price. Without testing, there is no objective way to confirm treatment efficacy.
Is HavenFog safe for people with chemical sensitivities?
HavenFog™ is formulated by Walter Hayhurst, RPh (PCCA), using citrus seed extracts with a Material Safety Data Sheet (MSDS) of all zeros for all hazard categories — no toxic ingredients, no harsh chemicals. It is used by practitioners who work with chemically sensitive patients. People with severe sensitivities should vacate the space during treatment and allow adequate ventilation before re-entry.
When should I call a professional instead of treating myself?
DIY fogging is appropriate for mold that is airborne or on non-porous surfaces in accessible spaces. Call a professional if: mold covers more than 100 sq. ft. of porous material (drywall, insulation, subfloor); HVAC systems are heavily contaminated; mold follows water intrusion from flooding or a plumbing failure; or household members are experiencing persistent health symptoms. AirWell provides certified mold assessment and remediation services.
