Fumigation handles a whole structure in a single treatment. A tent goes over the building and a gas is released that seeps into walls, furniture and everything stored inside. It is the heaviest bed bug option and is kept for cases that have spread through a house or small building.
When Tenting Makes Sense
- Bugs are in most rooms, not only the bedrooms.
- Earlier heat or chemical work did not solve it.
- There is too much stored property to treat item by item.
- A small multi-unit building needs every unit done at once.

Fumigation in San Ysidro
Tenting is more common for single-family houses and small buildings than for large apartment complexes, where heat or chemical work is usually easier to organize. If your San Ysidro lot has a house plus a rear unit, ask whether both structures are part of the quote. A good company explains in writing why tenting beats the other options for your property.
How to Prepare
- Pack groceries, pet food and medicine into the special bags the fumigator provides, or take them along.
- Line up 2 to 3 nights elsewhere for the household and pets.
- Water plants near the walls and cut back anything touching the building.
- Unlock gates and clear side yards so the crew can reach every wall.
Questions About Fumigation
How long do we have to stay somewhere else?
Plan on 2 to 3 nights, until the structure has aired out and passed air testing.
Does fumigation keep bed bugs away for good?
No. Nothing lingers after the gas clears, so a bug carried in next month can begin a fresh problem. Many companies add a residual treatment after tenting.
