If you are getting ready for tenting, the fumigation gas inside the structure is usually sulfuryl fluoride, sold in the U.S. under the brand name Vikane. It is used to kill drywood termites and other wood destroying pests by filling the sealed building with a gas that penetrates deep into wood and hidden voids. The process is serious, but with the right preparation and utility coordination, it is a controlled pest treatment, not a mystery event.

What Fumigation Gas Is and What It Does

Fumigation gas is a pesticide in gas form that gets into places sprays and dusts cannot reach. For whole structure fumigation, pest control companies seal the home with a tent, introduce the gas, and hold it at a set concentration long enough to kill the target pest. Sulfuryl fluoride is the standard choice for structural fumigation because it moves through lumber, wall voids, and attic spaces without leaving residue on surfaces.

Why homeowners hear about Vikane

Vikane is the best known brand name for sulfuryl fluoride fumigation gas. When a company says the home is being “gassed,” this is the product they are usually referring to. It is not used for routine indoor spraying, and it is not the same thing as odor control fogs or wasp treatments. The entire home must be vacated and sealed before treatment begins.

How Structural Fumigation and Tenting Work

Structural fumigation starts with inspection, sealing, and tent setup. The crew covers the building with a heavy tarp, seals the edges, and places warning signs at every entry point. Once the tent is secure, the gas is introduced and monitored for the exact treatment period set by the pest control company based on the structure, pest, and temperature conditions.

The basic sequence

  1. The pest company inspects the home and confirms fumigation is needed.
  2. You prepare the house by removing food, medicine, plants, pets, and people.
  3. The tent is installed and the home is sealed.
  4. The fumigation gas is released and held for the required time.
  5. The structure is aerated before anyone reenters.

After aeration, the crew uses clearance procedures to make sure the home is safe for reentry. The important point for homeowners is simple, no one goes back inside until the pest control company clears the structure.

Safety: What Homeowners Need to Know

Sulfuryl fluoride is lethal to insects and dangerous to people and pets inside the tented building. That is why strict vacancy rules apply. The home must be empty, and nobody can remain inside during fumigation. The company also posts notices and controls access, because the treatment area is a temporary hazardous zone.

What to remove before fumigation

  • People, pets, and aquarium animals
  • All food, open food packaging, and pet food
  • Medicine, vitamins, and personal care items
  • Plants, cut flowers, and produce
  • Anything that is sealed according to the fumigator’s prep list, if the company says to remove it

Do not rely on guesswork here. The fumigation company gives a prep notice, and you follow that list exactly. If you are unsure whether an item stays or goes, ask the fumigator before moving it.

Utility Questions, Gas Shutoffs, and Local Utility Requirements

Many homeowners search for gas company fumigation because utilities need attention before tenting. For most homes, the utility company or fumigator coordinates access to the meter area, pilot lights, and shutoff requirements. If the home uses natural gas, the gas service is commonly turned off at the meter before treatment and restored after the home is cleared. Electricity is handled separately and is usually kept on for monitoring, lighting, or equipment needs unless the fumigator says otherwise.

So Cal Gas fumigation and PG&E gas turn off for fumigation

If you are in Southern California, people search for SoCal Gas fumigation because Southern California Gas Company may need to shut off or restore service in coordination with the tenting schedule. On the utility side, the exact process depends on the address, appliance setup, and local service rules. In Northern California, PG&E gas turn off for fumigation follows the same basic idea, but the utility used and the scheduling steps are different. The fumigator and the gas company coordinate timing so the structure can be sealed, treated, and later reconnected safely.

Where to look for the utility process

Searches for socal gas fumigation web page or socal gas fumigation are about getting the utility steps right, not changing the pest treatment itself. The useful takeaway is to call the fumigation company first, then confirm the gas utility appointment they require. Do not assume your furnace, water heater, or stove can stay active through tenting. The fumigator decides what must be shut down and what must be relit after clearance.

What Fumigation Costs and What Affects the Price

Structural fumigation is a major service, and cost depends on the size of the structure, pest pressure, location, and how much prep is needed. A single-family home can cost from about $1,500 to $4,000 or more, with larger homes and complicated setups running higher. Multi-unit structures, detached garages, and difficult access points add to the bill.

What drives the total

  • Square footage and number of stories
  • Type of pest, especially drywood termites
  • Travel distance and local permit requirements
  • Utility coordination and relight service
  • Repairs or sealing work needed before tenting

Ask for a written estimate that separates fumigation, prep, utility coordination, and relight fees. That makes it easier to compare bids and avoid surprise charges.

How to Prepare Your Home the Right Way

Good preparation protects your belongings and keeps the schedule on track. The fumigator gives a prep sheet, and you complete every item before the tenting date. Food handling is the most common homeowner mistake, so pay close attention to pantry items, refrigerator contents, and anything in sealed packaging that the company tells you to remove or bag.

Simple preparation checklist

  1. Pack personal items you need during the vacancy.
  2. Remove all people, pets, and plants from the property.
  3. Dispose of or move food and medicine as instructed.
  4. Unlock gates, attic access, and areas the crew must reach.
  5. Arrange where you will stay while the home is tented and aerated.

Keep car keys, chargers, and essential documents with you. Once the tent is up, access is limited until the company finishes the treatment and clearance process.
