Fumigation is a whole-structure solution. The building gets tented and filled with a gas that penetrates walls, furniture and belongings all at once, which makes it the most complete bed bug option available, and one that companies reserve for cases where the problem has already spread through most of a home or building.
When It Is the Right Call
- Bed bugs have shown up in nearly every room already.
- Heat or chemical treatment was already tried without clearing it.
- There are simply too many belongings to treat item by item.
- A small apartment building needs every unit handled together, on the same timeline.
The Process Under California Rules
- AssessmentThe company measures the structure and hands over a checklist of what needs bagging or removing.
- Sealing upTarps go over the building and warning placards are posted.
- Gas releaseA licensed fumigator introduces the gas for the state-required exposure time.
- ClearanceTarps come off, the structure airs out, and air testing confirms it is safe.
A Process San Diego Homeowners Already Half Know
Anyone who has tented a house for termites has essentially seen this process before. It gets reserved for severe infestations in single-family homes and smaller apartment buildings, and it usually takes some advance coordination with tenants or an HOA. It is worth asking the company directly why tenting is the better call for your specific situation over heat or chemical treatment.
Preparing the Home
- Take out food, medicine and pet food, or seal them in the fumigation-rated bags the company supplies.
- Plan for everyone, including pets, to be out of the home for 2 to 3 nights.
- Water plants near the foundation and trim back any branches touching the house.
- Give the crew clear access for both the tenting setup and the later clearance test.
Fumigation Questions
Can we move back in right when the tent comes off?
Once a licensed fumigator has ventilated the structure and air testing confirms it is clear, yes.
Will fumigation keep bed bugs from ever coming back?
No. It leaves nothing behind as residue, so a new bug arriving later on luggage or furniture could still start a fresh problem. Some companies add a light residual treatment afterward for that reason.
