Yes — mold fogging with the Mold Bomb Fine-Particulate Fogger can cause respiratory irritation during application, which is why all people and pets must vacate the treated space and remain out for the full re-entry period stated on the label.

The Mold Bomb Fine-Particulate Fogger is a pressurized flammable aerosol, and direct inhalation during dispersal is the primary risk. The product is not designed to be breathed in — it's designed to work in an unoccupied room. Once the re-entry window has passed and the space has been properly ventilated, residual risk drops significantly. The grounded particulates the fogger pulls down to surfaces should then be cleaned up with a surface antimicrobial like Biocide 100, since settled mycotoxin-carrying particles remain a health concern if left in place.

  • All people and pets must vacate the space before activating the Mold Bomb Fine-Particulate Fogger.
  • The Mold Bomb Fine-Particulate Fogger is classified as a flammable pressurized aerosol that may cause respiratory irritation on direct inhalation.
  • Re-entry timing is specified on the Mold Bomb product label — do not return early based on odor alone.
  • Dead mold spores still carry mycotoxins; grounded particulates must be cleaned from surfaces after fogging to reduce ongoing exposure risk.
  • One 6oz Mold Bomb can treats up to 100 sq ft — under-treating a space leaves higher residual airborne particulate load post-treatment.

Safety Notes

  • Vacate before activation: All people and pets must leave the space before pressing the Mold Bomb Fine-Particulate Fogger tab — no exceptions, including infants and anyone with respiratory conditions.
  • No open flames or ignition sources: The Mold Bomb Fine-Particulate Fogger is a flammable pressurized aerosol — extinguish pilot lights and unplug electronics that cycle on before treating enclosed spaces.
  • Follow label re-entry time exactly: Do not re-enter based on odor clearing alone; the Mold Bomb label specifies a minimum re-entry window that must be observed regardless of how the room smells.
  • Clean grounded particulates after treatment: Settled mycotoxin-carrying particles on surfaces after fogging still pose an inhalation risk — wipe down with Biocide 100 surface antimicrobial before resuming normal use of the space.
  • Ventilate before extended re-occupancy: After the re-entry window, open windows or run the BioMatrix Air Scrubber before spending extended time in the treated space, particularly in low-airflow areas like crawlspaces or basements.
