When fumigation is the right choice
A qualified termite inspector may discuss fumigation when drywood termite activity is widespread or difficult to reach with localized treatment. Localized methods can be suitable in some situations, while whole-structure fumigation has substantial preparation and temporary-vacating requirements. The appropriate option depends on inspection findings and the structure.
Fumigation does not treat subterranean termites in the soil. If both types are present, they may require different treatment methods. Ask the inspector to identify each type and explain the recommended plan for the structure and soil-related activity.
How tenting works
The house is covered with heavy tarps that are sealed at the ground and clipped together. A licensed fumigator releases a gas fumigant, usually sulfuryl fluoride, inside the sealed structure. The fumigant is intended to penetrate the structure and control drywood termites in treated areas. The licensed fumigator must follow the product label, required exposure conditions and applicable safety procedures.
After the set exposure time, the tarps come off and the house is aired out. The fumigator uses gas-detection equipment to confirm the air is clear before anyone is allowed back inside.

Most of the work on your end is preparation. The fumigation company gives you a written checklist. These are the items on almost every list.
- Plan for people, pets and indoor plants to leave for the period specified by the licensed fumigator; the exact schedule depends on the job and required clearance.
- Remove or double-bag food, medicine and pet food in special fumigation bags provided by the company. Items in unopened factory-sealed glass or metal containers can usually stay.
- Arrange for the gas service to be shut off at the meter. The fumigator will usually coordinate this, and the gas company relights pilots afterward.
- Trim plants and shrubs back from the walls and water the soil around the house the day before. Wet soil helps keep the gas from escaping under the tarp.
- Open interior doors, cabinets, drawers and closets so the gas can circulate.
- Remove valuables and anything you do not want to leave in an unattended house. Fumigated homes have secondary locks on doors, but take valuables anyway.
- Tell your neighbors, especially in the tighter lots around downtown Arcadia where the tarp may come close to a property line.
Fumigation timeline
Inspection
Call (626) 597-0007. An inspector confirms drywood activity and measures the home.
Prep day
You bag food and medicine, water the perimeter, and move out. The crew trims back any branches or vines that would block the tarps.
Day one: tarps and gas
The crew covers the house, seals the tarps and releases the fumigant. Warning signs go up.
Day two: exposure
The gas sits in the structure for the required time, usually about a day.
Day three: aeration and clearance
The tarps come off, the house airs out, and the fumigator tests every room before signing off on re-entry.
Fumigation versus local treatment
| Fumigation | Local treatment | |
|---|---|---|
| Reaches hidden termites | Yes, all wood in the structure | Only wood the technician can reach |
| Move out required | Yes, about 2 to 3 nights | No |
| Lasting protection | None after aeration | Limited to treated wood |
| Best for | Widespread or hidden infestations | One or two small, accessible areas |

Termite fumigation FAQ
Is it safe to go back in after fumigation?
Do not re-enter until the licensed fumigator has completed the required testing and explicitly cleared the structure. Follow the provider’s written instructions for food, medicines, dishes, clothing and other belongings.
Will fumigation kill my plants?
Indoor plants must be removed. Outdoor plants right against the walls can be damaged where the tarp touches them, which is why the crew trims them back and why watering the soil beforehand helps.
Does fumigation kill other pests too?
Fumigation may affect other pests present inside the treated structure, but it is designed for the target infestation and does not prevent pests from entering again. Ask the provider which pests are covered by the treatment.
How often do Arcadia homes need to be tented?
There is no set schedule. Some homes go many years between fumigations. Regular inspections and good exterior maintenance stretch that time out.
