The Fumigation Process
See each stage of structural fumigation, from preparation and tenting through treatment and aeration.
What Happens During Structural Fumigation?
Structural fumigation is a carefully coordinated process designed to treat the entire enclosed property. Before work begins, the property must be properly prepared and all occupants, pets, plants, and other required items must be removed or handled according to the preparation instructions provided for the project.
Once the property is ready, the fumigation team prepares the structure for treatment by enclosing and sealing it as required for the project. The property is secured, warning notices are posted, and access is restricted so the fumigation can proceed under controlled conditions.
After the structure has been properly prepared and secured, the fumigant is introduced and maintained for the required treatment period. The amount of fumigant and exposure time vary according to factors specific to the structure and fumigation plan. During treatment, the property remains completely unoccupied and unauthorized entry is prohibited.
When the treatment period is complete, the property enters the aeration phase. Fresh air is circulated through the structure and the fumigant is allowed to dissipate while the site remains under controlled access.
Before occupants are permitted to return, the fumigation professional must complete the required clearance testing. The structure remains restricted until the fumigant concentration has reached the established clearance level and the property has been released for re-entry.
Once clearance has been confirmed, occupants may return according to the instructions provided for the project. Customers should wait for official notification rather than assuming a property is ready for occupancy based solely on the appearance of the structure or the removal of fumigation materials.

THE FUMIGATION PROCESS
Your Fumigation From Start to Finish
Here’s what to expect at each stage of a typical fumigation with First Class Fumigation.
Project Coordination
The pest control company coordinates the fumigation with First Class Fumigation and provides the property-specific schedule and preparation requirements. This keeps the inspection, treatment recommendation, and fumigation roles clearly defined throughout the project.
Preparing and Vacating the Property
Before fumigation begins, occupants complete the required preparation steps and leave the property. Pets, plants, food, medications, and other items must be handled according to the preparation instructions provided for the project.
Enclosing and Securing the Structure
The property is enclosed with fumigation tarps and carefully sealed. Entry points are secured and warning notices are placed to prevent unauthorized access while the property is under fumigation.
Treatment
Once the structure has been properly enclosed, the fumigant is introduced and maintained for the required treatment period. The property remains completely unoccupied and secured throughout this stage.
Aeration
When treatment is complete, the property enters the aeration phase. The fumigant is removed and fresh air is circulated through the structure while access remains restricted.
Clearance and Re-entry
Before the property can be occupied again, the fumigation professional performs the required clearance testing. Only after the property has been cleared for re-entry should occupants return.
Important to Know
Do not enter the property until you have received official clearance that it is safe to return. Re-entry is only permitted after the structure has completed the required aeration and clearance process.
