Is termite fumigation always required in Irvine homes?

No. Many Irvine homes are attached - condos, townhomes, and some duet-style properties - which makes full fumigation impractical or restricted by HOA rules. In those cases, licensed local (spot) treatment is commonly used and is widely accepted by lenders during escrow.

Can a home be fumigated while in escrow?

Yes. Fumigation is regularly coordinated during escrow in Orange County. The fumigation company schedules tenting, aeration, and a clearance notice that gets delivered to escrow, typically all wrapped up before the close-of-escrow date so the buyer takes possession of a cleared home.

What is the difference between local termite treatment and fumigation?

Local treatment targets specific active areas - usually with foam, dust, or borate products - and is well suited to attached homes where tenting is not possible. Fumigation tents the entire structure and uses a measured dose of fumigant gas to reach hidden voids. For widespread drywood termite activity in a detached single-family home, fumigation is often the more thorough option.

How long does fumigation take in Orange County?

Most single-family fumigations in Orange County take roughly 48 to 72 hours from start to clearance. The home is tented and treated, then aerated and tested until fumigant levels are below the U.S. EPA re-entry standard. The licensed fumigator posts a clearance notice once the structure is certified safe to re-enter.

Who pays for termite work in an Irvine real estate transaction?

It is negotiable and depends on the contract terms. In Orange County, it is common for the seller to handle Section 1 (active infestation) items so the home delivers cleared at close of escrow, while Section 2 (conditions that could lead to future infestation) items are negotiated case by case. Your agent should review the termite report carefully and negotiate based on the inspection findings, loan requirements, and overall deal economics.
