Fumigation is the option that treats an entire structure in one shot. A tent goes over the whole building, and a gas is released that reaches into walls, furniture and belongings wherever they sit. It is reserved for cases where bed bugs have spread across most of a home or building.
Signs It Might Be the Right Call
- Bed bugs turn up in room after room, not just where people sleep.
- A round of heat or chemical treatment did not clear things up.
- There is more furniture and clutter than a spot treatment could reasonably cover.
- Several units in a small building all need to be handled on the same day.
The Fumigation Process Under California Rules
- Measure and planThe company sizes up the structure and hands you a checklist of what to remove or bag.
- Tent goes upTarps cover the building and posted signs warn people away.
- Gas releasedA fumigator holding a Branch 1 license runs the gas for the time the job requires.
- Air out and clearThe tent comes down, the building ventilates, and air testing confirms it is safe to re-enter.
Fumigation on the Island
A lot of Coronado homeowners already know the drill from termite tenting, and the bed bug version follows a similar path. Row houses and close-set lots on the island mean the crew has to coordinate around neighbors, and a solid quote will explain why tenting was picked over heat or chemical treatment for your specific home.
Preparing Before the Crew Arrives
- Remove or seal food, medicine and pet food in the bags your fumigator supplies.
- Line up somewhere to stay for 2 to 3 nights, for people and any pets.
- Water plants near the foundation and trim back branches touching the house.
- Make sure the crew can access the property for both tenting and the final clearance.
Questions About Fumigation
How many days should we plan to be elsewhere?
Plan on 2 to 3 days while the building airs out and air testing confirms it is clear to re-enter.
Does fumigation keep bed bugs from coming back?
No. It leaves no residue, so new bugs brought in later, for example after a trip or a guest stay, can start over. Many companies add a residual treatment after.
