Fumigation treats a whole structure at one time. Crews cover the building with tarps and release a gas that seeps into wall cavities, furniture and every stored box. It is the most intensive bed bug method and is kept for problems that have spread through a house or small building.
When Tenting Makes Sense
- Bugs have reached most rooms, not just where people sleep.
- Heat or chemical treatment has been tried without success.
- There are too many belongings to treat item by item.
- A small building with several sleeping rooms needs all of them done together.

Fumigation Around Graton
On farm parcels near Graton, people may sleep in more than one building, such as a main house, a cottage and a bunk room. Ask whether each one needs treatment or only the building with bugs. Tenting also needs clear ground around the structure, so vines, trellises or stacked equipment close to the walls may need attention first. Expect the written quote to say plainly why tenting is a better fit here than heat or chemical work.
How to Get Ready
- Pack food, medicine and pet food in approved bags or take them out.
- Arrange 2 to 3 nights elsewhere for everyone, animals included.
- Water plants along the walls and trim back anything touching the building.
- Open gates and clear access so the crew can work all the way around.
Questions About Fumigation
How long must everyone stay away?
Usually 2 to 3 days, until the structure is aired out and cleared by air testing.
Will tenting prevent bed bugs from returning?
No. Fumigation leaves no residue, so bugs brought in later can start fresh. Many companies follow it with a residual treatment.
