Fumigation treats a whole structure at once. The building is sealed under a tent and filled with a gas that moves through walls, furniture and stored belongings. It is the heaviest bed bug option and is kept for problems that have spread through a house or small building.
When Tenting Makes Sense
- Bugs have moved well beyond the bedrooms into most of the home.
- Heat or chemical treatment was tried and did not work.
- There are too many belongings to treat item by item.
- A small multi-unit building needs every unit done together.
How Structural Fumigation Works in California
- Size upAfter measuring the building, the fumigator gives you a prep checklist on paper.

- FumigateThe gas goes in under a licensed fumigator and stays for the labeled exposure period.
- ClearWith the tarps off, the building vents until air readings show it is safe.
Tenting in San Pablo
Tenting is more common for a detached house or a small duplex than for a large complex, where heat or chemical work unit by unit is usually more practical. If you own a lot with a second unit, ask whether both structures are included in the quote. A good fumigator explains in writing why tenting is better than the other options for your building.
How to Prepare
- Pack food, pet food and medicines in the special bags provided, or take them along.
- Line up 2 to 3 nights somewhere else for everyone, pets included.
- Soak the soil beside the foundation and trim plants that touch the siding.
- Unlock side gates and clear paths so the crew can reach every side.
Questions About Fumigation
How long do we have to stay away?
Plan on 2 to 3 nights, until the building is aired out and air testing clears it.
Does fumigation keep bed bugs from returning?
No. It leaves no residue, so bugs brought in later can start over. Many companies follow up with a residual treatment.
