Fumigation goes after an entire structure in a single pass. Once the building is wrapped in a tent, a gas is released that reaches into walls, furniture and belongings alike. It is the heaviest option on this list, reserved for cases where bed bugs have spread throughout a home or a building.
When It Makes Sense
- Bugs have turned up in nearly every room, not just the bedrooms.
- A previous round of heat or chemical treatment did not fully clear it.
- There is simply too much furniture and clutter to treat piece by piece.
- A small apartment building needs its units tented together in one pass.
The Process Under California Rules
- Measuring and planningThe fumigator sizes up the structure and gives you a list of what to remove or bag.
- Sealing the tentTarps go up over the building along with posted warning signs.
- Releasing the gasA licensed fumigator applies the gas for the length of time required.
- Airing outThe tent comes down, the structure ventilates, and the air is tested before anyone re-enters.
Fumigation Around La Mesa
Plenty of La Mesa homeowners have already seen tent fumigation used for termites, and the bed bug version follows a similar playbook. It comes up for serious infestations in houses and small apartment buildings, and it takes some coordinating with neighbors and tenants ahead of time. A good company will explain clearly why tenting, rather than heat or chemicals, is the right call for your situation.
Preparing for Fumigation
- Remove food, medicine and pet food, or seal them in the fumigation-rated bags the company supplies.
- Line up 2 to 3 nights elsewhere for both people and pets.
- Water plants near the foundation and cut back any branches touching the structure.
- Make sure the crew has clear access for tenting and for the final clearance check.
Questions About Fumigation
When can we move back in after fumigation is done?
Once a licensed fumigator has ventilated the structure and confirmed through air testing that it is clear, it is safe to return.
Does this prevent bed bugs from ever coming back?
It does not. There is no residue left behind, so bugs carried in later on luggage or furniture could start a new problem. Plenty of companies follow up with a residual treatment to help guard against that.
