Drywood Termite Fumigation in Orange County

Protect your property from hidden Drywood termites with expert whole-structure fumigation by Orion Exterminating.
Drywood termites can cause significant structural damage before they’re ever detected, making early and effective treatment essential. Unlike other pests, these termites live entirely within wood, bypassing soil contact and forming colonies in attics, walls, furniture, and framing—often without obvious warning signs.

At Orion Exterminating, we specialize in Drywood termite fumigation services for residential, commercial, and real estate properties throughout Orange County and Long Beach, California. With decades of experience and a focus on long-term protection, our team uses Vikane® gas fumigant, the industry standard for full-structure fumigation.

This trusted treatment penetrates deep into the wood and reaches areas that spot treatments can’t access, ensuring complete eradication of both visible and hidden termite colonies. Whether you’re responding to a severe infestation or preparing for a real estate transaction, our licensed professionals are here to help.

Why Whole-Structure Fumigation Works

Drywood termites live deep within the wooden structure of your home—often invisible until the damage is done. They can colonize attic beams, interior walls, floors, and furniture. Unlike spot treatments that target visible infestations, whole-structure fumigation treats the entire building in one comprehensive process.

Fumigation with Vikane® gas reaches:

  • Interior wall voids
  • Sub-roofing and crawl spaces
  • Framing, flooring, and support beams
  • Satellite termite colonies

Tenting and sealing the structure allows for total saturation, ensuring that even undetected termite colonies are eradicated without drilling, mess, or guesswork.

Our Fumigation Process

Orion Exterminating makes the fumigation process as smooth and stress-free as possible. Here’s what to expect:

1. Property Inspection

A licensed termite inspector will evaluate your property, confirm the presence of Drywood termites, and determine if whole-structure fumigation is the right solution.

2. Tenting & Treatment

The structure is sealed with a professional fumigation tent. We then introduce Vikane® gas, which penetrates all wood areas to eliminate termites throughout the building.

3. Post-Treatment & Clearance

After safe aeration and air quality testing, we provide re-entry clearance. If needed, we’ll also issue a report or clearance letter and advise on preventative steps.

Why Choose Orion Exterminating?

In addition to fumigation, we offer termite inspections, localized treatments, and preventative control programs tailored to your needs.

When Should You Consider Fumigation?

Whole-structure fumigation is the most effective way to eliminate Drywood termites, especially when infestations are widespread or hard to detect. You should consider fumigation if:

  • Termites are found in multiple areas of your home or building

  • Previous spot treatments have failed or the infestation has returned

  • A real estate transaction or escrow requires a clearance letter

  • You want the most comprehensive protection against hidden colonies

Even if you’re not selling, fumigation helps preserve your property’s structural integrity and value by stopping damage at the source. It’s a proactive choice that can save you money on costly repairs later.

If you’re unsure whether fumigation is the best option, our licensed inspectors will assess the situation and provide expert guidance to help you make an informed decision with confidence.

Drywood vs. Subterranean Termites

Knowing the difference between Drywood and Subterranean termites helps determine the right treatment approach. While both species damage wood, their habits and treatment methods are very different.

Drywood Termites:

  • Live entirely inside wood—no soil contact needed
  • Found in walls, attics, furniture, and trim
  • Leave dry, pellet-like droppings (frass)
  • Typically require whole-structure fumigation

Subterranean Termites:

  • Nest underground and build mud tubes to access wood
  • Prefer damp areas like foundations and crawl spaces
  • Often treated with soil-applied termiticides or baiting systems

If you’re unsure which type is causing damage, our inspectors will identify the species and recommend the most effective solution for your property.
