Fumigation treats an entire building at once. The structure is sealed, usually under a tent, and filled with a gas that reaches every wall void, drawer and piece of furniture. It is the heaviest option, and it is used when bed bugs have spread through a whole home or keep coming back.
When Fumigation Makes Sense
- Bed bugs are in many rooms, furniture and walls throughout the home.
- Heat or chemical treatment has not solved the problem.
- The home is full of belongings that would be hard to treat one by one.
For most Carlsbad homes with bugs in one or two rooms, heat or chemical treatment is simpler. A good company will tell you honestly if fumigation is more than you need.
How Structural Fumigation Works in California
In California, structural fumigation is done by companies licensed by the Structural Pest Control Board for fumigation work (Branch 1). The gas most often used is sulfuryl fluoride. The process follows strict safety steps:
- PrepEveryone leaves, along with pets and plants. Food and medicine are sealed in special bags or removed.
- SealThe home is covered with a tent or sealed, warning signs go up and secondary locks go on the doors.
- TreatThe gas is released and held for the time set on the label for bed bugs.
- ClearThe home is aired out and tested with a meter before anyone is allowed back in.
Fumigation and Carlsbad Homes
Carlsbad has a lot of attached housing, such as townhomes and condos with shared roofs. Fumigating one unit in an attached building usually means working with the HOA and the neighbors, which takes planning. Ask the company early how they handle attached homes.
How to Prepare
- Arrange a place to stay for you, your family and pets.
- Follow the company's list for food, medicine and items to bag or remove.
- Water the soil around the home if asked, and trim plants away from the walls.
- Leave keys with the company for the secondary locks.
Questions About Fumigation
Does fumigation leave anything behind?
The gas airs out and does not leave a lasting residue, which also means it gives no protection against new bed bugs brought in later.
Can a single apartment be fumigated?
Tenting usually covers a whole building. For a single unit, heat or chemical treatment is more common. Ask the company what fits your building.
