Fumigation covers a whole structure in one pass. Tarps seal the building and it is filled with a gas that reaches into wall cavities, furniture and belongings alike. It is the heaviest option on the list, saved for infestations that have spread across most of a home or building.
When Tenting Is the Right Call
- Bed bugs show up in most rooms, not just the bedrooms.
- A previous round of heat or chemical treatment did not resolve it.
- There is too much stored property to treat piece by piece.
- A small multi-unit building needs everything done at once.
How Fumigation Works Under California Rules

Fumigation Around Spring Valley
A number of Spring Valley homeowners have already seen a tent go up for termites, and the bed bug process runs much the same way. It comes into play for heavy infestations in houses and smaller apartment or duplex buildings, and on hillside lots it takes some coordination with the neighbors nearby. Ask the company to walk through why tenting beats heat or chemicals for your specific situation.
Getting Ready to Leave
- Remove food, medicine and pet food, or bag them in the company-approved sleeves.
- Line up 2 to 3 nights of housing for people and pets.
- Give foundation plantings a good soak beforehand and clear branches away from the exterior walls.
- Make sure the crew has full access for tenting and for clearance afterward.
Questions About Fumigation
When is it actually safe to move back in?
Once the licensed fumigator has fully aired out the structure and follow-up air testing confirms the gas has cleared, reentry is safe.
Does fumigation prevent a future infestation?
It does not. The gas dissipates completely and leaves nothing behind, so bed bugs brought in later on luggage or furniture could start a new problem. Many companies pair fumigation with a residual product afterward to reduce that risk.
