Termite Inspection Before Selling a House in Arizona 2026: Who Pays, What to Disclose, and When to Treat

Maybe you spotted mud tubes running up the garage wall. Maybe a neighbor just had their house done. Or maybe you half remember a pest guy coming out years ago and have no idea what he sprayed. Either way you are weeks from listing and deciding whether to call somebody, say nothing, or just treat it and move on. Here is how a termite finding moves through a sale, what the report covers, and who ends up paying.

Pull the treatment history first, then decide on the inspection

Start with the file that may already exist. The Arizona Department of Agriculture Office of Pest Management keeps a database of wood destroying insect inspection reports and post construction termite treatments performed on homes, so your house may already have a documented history a buyer's agent can ask about. If it was treated in 2019 and that treatment carries a transferable warranty, that is an asset you hand over at closing. If an old report shows activity and nothing shows a treatment, you want to be the one who finds out.

Then decide on the inspection. My opinion, after watching these play out: in most resales here it is worth the couple hundred dollars to order your own before you list. Not because termites are a crisis, but because a report turns a vague worry into a line item with a price on it, and line items negotiate in a way surprises never do.

What a wood destroying insect report actually covers, and what it does not

Visible evidence, and nothing beyond it. The state pest management office is direct about the scope: the report documents visible evidence of infestation or previous treatment, notes areas that were obstructed or inaccessible, names who is responsible for correcting damage, and includes a diagram of the findings. It is explicitly not a structural damage report, and it does not certify the house is free of wood destroying insects.

So do not promise a buyer a certificate that does not exist. And watch that inaccessible areas line, because it is where arguments start. Boxes against a baseboard, a flower bed mounded against the stucco: each gets written down as not inspected, and each gives a nervous buyer a reason to ask for a second look. Clear the perimeter and the garage walls first, the same way you would for a pre listing home inspection. What the inspector is hunting for in houses from Mesa to Goodyear:

• Mud tubes. Pencil width dirt tunnels running up block, stucco, or a garage wall. The most common finding on a desert resale.
• Discarded wings. Usually on a windowsill after a monsoon rain, when colonies send out reproductives.
• Moisture against the foundation. Drip lines, a leaking hose bib, grading that sends water toward the slab. This is the part you can fix yourself for nothing.

Why desert houses get treated more than once

Because the termites never left the soil. Subterranean species live in the ground and come up through the slab, the block, and the expansion joints, so a treatment is a chemical barrier with a service life, not a cure. A house treated eight years ago is not permanently protected, and that is ordinary rather than alarming.

So sellers should stop getting defensive when a report shows previous treatment. It does not brand the property. Treatment with an invoice and a warranty reads better to an experienced buyer's agent than no history at all, because it says somebody paid attention. What hurts is the opposite: activity you knew about and never handled, or a warranty that lapsed three renewals ago. Keep the paperwork.

What you have to disclose, and what the market says it costs you

Everything you know. The seller property disclosure statement used in most residential resales asks directly about past and present pest problems and about treatments, and the standard is what you actually know, not what somebody could prove. Had it treated? Say so and attach the invoice. Saw tubes last spring and knocked them down with a hose? Still a yes, with an explanation. Our breakdown of what the disclosure form requires covers the rest of the form.

Then look at the leverage math honestly. Phoenix REALTORS reported 79 days on market until sale in September 2026, 98.0 percent of list price received, and a 4.5 month supply of inventory. Redfin's Data Center put price drops at 38.6 percent of Phoenix listings that same month. A buyer with that many choices does not have to tolerate a surprise in week two. They can demand treatment, repair, and a credit, or go look at the next house. That is the real cost of waiting for their inspector to find what you suspected.

Estimate what you would walk away with

When to treat before you list, and when to leave it alone

Treat now if there is active activity. Leave it alone if there is only history. The middle case takes some thought.

• Active activity. Treat it, keep the invoice, buy the transferable warranty if the company offers one, disclose all three. Handled is a non event. Found by their inspector is a renegotiation.
• Old evidence, nothing live. Do not treat preemptively. You would be buying a line item nobody asked for. Disclose the history and let the report speak.
• Visible damage, unclear cause. Get the report, and if the damage is anywhere near framing, get a contractor bid. This is where sellers guess wrong, and where an inspector writing the word structural costs far more than the bid would have.

I would rather see a seller spend a thousand dollars on treatment with documentation than eight thousand on cosmetic updates that photograph nicely. The first removes an objection, the second raises expectations. More on that tradeoff in what to fix before you sell and what to skip.

Who pays, and why the buyer's loan gets a vote

Usually the seller, by the time it is settled. Treatment is cheap next to the leverage a finding gives a buyer, so most of these end with the seller covering treatment and repair of visible damage, directly or as a closing credit. What changes the size of that bill is how your buyer is paying.

Government backed financing is the strict end. The appraiser is looking at safety and soundness, so visible insect damage can become a required repair before the loan funds rather than a negotiation between the two of you, and a VA buyer commonly arrives with a wood destroying insect report requirement in the file. That program also limits which fees the veteran may pay, which is how that cost tends to land on the seller's side of the settlement statement. Conventional buyers have more room. Cash buyers have the most and often care the least. Knowing which one you have before you counter is worth more than any script, and if you want the lending read on an offer in hand, our loan programs page shows what we work with.

Where this advice has limits

This is a general explanation of how these sales tend to go, not legal advice, and a disclosure question with real liability attached deserves an attorney rather than a blog post. Three honest caveats.

Inspectors are not interchangeable. Only a licensed pest control business can prepare the report, the notes and diagram vary in quality between companies, and you can verify a license through the state pest management office before you hire anybody.

Warranties are not interchangeable either. Some transfer to a buyer and some do not, some cover retreatment only. Read the transfer language before you advertise it as a benefit, because a warranty you promised and cannot transfer is worse than none.

And nobody can promise a pest finding costs you nothing, or that the house sells on a schedule or at a set price. Not every agent is the right fit for a property with a pest history, and a big following is not the same thing as having closed one. You want somebody who will put the number in writing before you sign. The full sequence is in our step by step guide to selling.

Frequently asked questions

Do I need a termite inspection to sell my house in Arizona?

No rule forces a seller to order one. In practice the buyer or the buyer's lender drives it, and a VA buyer commonly arrives with a wood destroying insect report requirement attached to the loan file. Ordering your own ahead of time is optional and usually smart, because it lets you price and fix a finding on your own schedule instead of during the inspection period.

Who pays for termite treatment when selling a house?

Usually the seller, once it is negotiated. Treatment is inexpensive compared with the leverage an active finding hands a buyer, so most settle with the seller paying for treatment and repair of visible damage, directly or as a credit. With government backed financing it is likelier to land on the seller, since the appraiser can require repairs before funding and the VA program limits which fees the veteran may pay.

Do I have to disclose termites if the house was already treated?

Yes. The standard is what you know, and a past treatment is squarely something you know. Disclose it and attach the invoice and any warranty. Sellers worry this scares buyers off and it is almost always the reverse: a documented treatment answers the question an inspector would raise anyway, while a blank line plus an inspector finding tubes makes a buyer wonder what else got left out.

Will termite damage kill my sale?

Active infestation and cosmetic damage almost never do, because both have a known fix at a known price. What kills sales is structural damage found late, or a seller who disputes a finding instead of pricing it. If damage reaches framing, get a contractor bid before you list, and expect a financed buyer to need the repair done before their loan funds.
