Fumigation treats a whole building in one go. The structure is covered with a tent and filled with a gas that works through walls, furniture and everything stored inside. It is the heaviest bed bug option and is saved for cases that have spread through the entire house.
When Tenting Makes Sense
- Bugs have spread well past the bedroom into most of the house.
- Heat or chemical work has already failed.
- The home is packed with belongings that would be hard to treat one by one.
- Bugs have reached wall voids throughout the building.
How Structural Fumigation Works in California
- InspectA fumigator looks over the house and hands you a written prep list.
- TentThe building is covered and warning signs go up.
- TreatGas is released and held at the level the label and state rules require.
- Air outThe tent comes off, the house vents and air readings confirm it is safe.
Tenting in Port Costa
Many Port Costa houses sit on steep canyon lots close to their neighbors, and a few buildings downtown are large and historic. The fumigator needs room to lay out and seal the tent, so talk through access, slopes and any attached structures at the estimate. Ask the quote to spell out why a tent suits your building better than heat or chemicals.
How to Prepare
- Pack food, medicine and pet food into the approved bags, or take them away.
- Book 2 to 3 nights elsewhere for everyone, pets included.
- Water plants near the walls and trim back branches touching the house.
- Unlock gates and side doors so the crew can reach every wall.
Questions About Fumigation
How many nights will we be away?
Plan on 2 to 3 days, until the building is aired out and air testing shows it is safe to come back.
Will tenting stop bed bugs from coming back?
No. Fumigation leaves no residue, so bugs carried in later on luggage or used furniture can start again. Many companies add a residual treatment afterward.
