This method is often used when pests are widespread or hidden in hard-to-reach areas. Routine structural fumigations are rarely used as a primary pest management program due to the time and cost involved.
What is structural fumigation?
Structural fumigation is a method used to help manage pests inside enclosed buildings or structures, generally warehouses and processing plants. It involves sealing the structure and releasing a fumigant gas that reaches hidden crevices where pests may be hiding.
What pests will structural fumigation deal with?
Structural fumigation is primarily used to treat severe insect infestations, especially pests that are difficult to reach with conventional methods. It's most commonly applied for wood-destroying insects like drywood termites and powderpost beetles. This type of fumigation pest service can have an immediate impact on advanced rodent and insect infestations, making it an appropriate solution in some circumstances. While it can also target pests like bed bugs, these are not commonly treated with structural fumigation.
Fumigants used with structural fumigation
Fumigants such as sulfuryl fluoride and phosphine—often used as alternatives to methyl bromide fumigation—are commonly applied in structural treatments. These gases are effective at reaching deep into a structure and, when applied correctly by pest control technicians, can help control a wide range of pests.
After treatment, the structure is ventilated to remove the remaining gas before re-entry.
What methods of structural fumigation are there?
There are two primary methods used in structural fumigation. Each one is selected based on the structure, pest type, and treatment goals.
Tent fumigation
Tent fumigation is a full-structure method used when pests are widespread or deeply hidden inside a building.
This type of fumigation involves covering an entire building with a large, sealed tarp or tent. The fumigant is then released inside the structure.
The method allows the gas to reach all parts of the structure, including walls, furniture, and hidden spaces. It’s often used when pest activity is widespread.
After treatment, the tent is removed, and the structure is ventilated. Air testing ensures that any remaining gas is cleared before anyone can enter.
Tape-and-seal fumigation
Tape-and-seal fumigation is a method used to treat buildings without covering the entire structure.
This fumigation method uses plastic sheeting and tape to seal doors, windows, vents, and other openings. It’s typically used in warehouses or commercial buildings.
Once sealed, a fumigant is introduced to the building. The gas spreads throughout the interior and helps manage pests without fully covering the exterior.
After exposure, the building is aired out with fans or ventilation systems. Trained technicians monitor gas levels before declaring the space safe for re-entry.
Industries that may require structural fumigation
Structural fumigation may be needed in several industries, including food processing and warehousing operations, especially when pests hide deep within stored goods or packaging.
Less common but still relevant uses include museums and libraries, where structural fumigation helps protect sensitive collections from wood-boring insects, though these services are used sparingly and carefully due to the delicate nature of the environments.

Frequently asked questions
Structural fumigation may be considered when pests are widespread, hard to reach, or not responding to other treatments. It is often used for termites, beetles, and other pests hidden deep inside walls, furniture, or flooring.
The full process usually takes between 24 and 72 hours. This includes the time needed to prepare the building, release the fumigant, allow exposure time, and properly ventilate the structure before re-entry.
When performed by trained technicians and under proper conditions, structural fumigation can be done safely. Strict safety guidelines are followed to make sure no one is exposed to the fumigant during or after treatment.
Before fumigation, all people, animals, and plants must be removed from the building. Food, medicine, and other sensitive items may need to be sealed or taken out. The fumigation team will provide clear instructions based on the structure and treatment plan.
No, most fumigants used in structural fumigation do not leave behind any residue. After treatment, the building is ventilated and tested before anyone returns.
