Fumigation treats a whole building at once. The structure is wrapped in a tent and filled with a gas that works its way through walls, furniture and everything stored inside. It is the largest bed bug option and is usually saved for infestations found in nearly every room.
When Tenting Can Make Sense
- Bed bugs have moved well beyond the bedrooms.
- Heat or chemical treatment did not finish the job.
- Rooms hold too many belongings to treat piece by piece.
- Bugs are established inside wall voids throughout the house.
How Structural Fumigation Works in California
- Site visitA licensed fumigator inspects the structure and hands you a written prep list.
- TentTarps go over the building and warning signs are posted.
- ReleaseThe fumigant goes in and stays at the strength set by its label and by California regulations.
- ClearOnce the tarps are off, fans air out each room and a meter check clears you to go back in.
Tenting on Howell Mountain
Tenting is unusual in Angwin because it takes a full crew, heavy equipment and several days on site, and sloped lots, oaks, pines and nearby brush can make sealing the tarps hard. If we suggest it, we give you a written reason why heat or chemical work would not be enough. Lodging for 2 to 3 nights is not allowed as a vacation rental in unincorporated Napa County, so book a permitted hotel or inn in the valley early.
Getting Ready
- Bag food, pet food and medicine in the fumigator's special bags, or take them along.
- Arrange 2 to 3 nights away for the whole household, pets too.
- Water the soil along the foundation and trim branches and shrubs that touch the walls.
- Move firewood stacks, ladders and outdoor gear away from the siding so the tent seals.
Questions About Fumigation
After an Angwin house is tented, when can the family return?
Plan on 2 to 3 days away while the building airs out and testing shows the air is safe to breathe.
Does fumigation keep bed bugs from coming back?
No. The gas leaves nothing behind, so bugs that ride in later on luggage or furniture can start over. Ask us whether a residual treatment should follow.
