How to Diagnose a Home: The Pest Control Inspection Sales Process

Two reps can knock the same door with the same plan at the same price. One lists features. The other asks what the homeowner has been seeing, walks the side of the house with them, and points at a web in the corner of the garage door.

The second rep has a much better conversation, because now the sale is about this home. That is what diagnosing means in pest control sales, and it is the part of the job most new reps skip.

A quick word on language. Reps often call this an inspection, and the keyword people search is inspection sales, but what you do is a sales diagnosis. Formal inspections, pest identification and treatment decisions belong to licensed professionals. Keep that line clear for yourself and for the homeowner.

What is the pest control inspection sales process?

The pest control inspection sales process is a repeatable way to ask questions, look at the property with the homeowner’s permission, share what you noticed, and recommend a service that fits. It sits between the opening of the conversation and the presentation of your price.

1. Prepare before the door. Look at the home and the street for what you can reasonably notice from the sidewalk.
2. Open the conversation. Introduce yourself honestly, including who you work for and why you are there.
3. Ask first. Find out what they have seen, where and for how long.
4. Get permission. Ask before you walk anywhere on the property.
5. Walk and observe. Stay focused on the areas tied to what they told you.
6. Share what you saw. Show them, in plain language, and say what you did not see too.
7. Set expectations. Explain what the technician will confirm and what the service does and does not include.
8. Recommend. Tie a specific plan to the specific things you discussed.

In the Pro Certification, Stages of a Pest Sale breaks the sale into Pre Interaction and Customer Interaction, and Pest Pro Tips – Marshall Hawkes includes a lesson called Diagnosing – The Consultative Approach. The steps above are our own general framework, so use them alongside whatever process your company teaches.

What should you do before you talk to the homeowner?

Before you talk to the homeowner, take a few seconds to notice what the property tells you. Kids’ bikes, a dog bowl, a garden, a woodpile, a pool or a new build each give you something to talk about and a question to ask.

Noticing is different from assuming. A web on the eave tells you there is a web on the eave. It does not tell you the home has a spider problem. Use what you see to start a question, and let the homeowner fill in the rest. The Prospecting module has a lesson called Signs of Life, Signs of Bugs that fits this part of the job.

What questions should you ask to diagnose a home?

Ask open questions about what the homeowner has seen, where they see it, and what they have already tried. Let them talk. The more they describe the problem themselves, the less you need to convince them it exists.

• “What kind of bugs do you see most around here?”
• “Where do you notice them, inside or out?”
• “Is it worse at certain times of year?”
• “What have you tried so far? How did that go?”
• “Is anyone servicing the home now? What do you like about it?”
• “If you could change one thing about bugs around the house, what would it be?”

Then listen for the problem behind the bug. One person hates seeing spiders in a child’s room. Another is tired of spraying the garage every weekend. The bug is the same category, but the reason they care is different, and your recommendation should speak to that reason.

Watch how they respond too. Marshall Hawkes has a lesson called Non-Verbals for Pest, and reading a homeowner’s posture and attention is a skill worth building. If they are checking the time, shorten the walk. If they step outside and start pointing at things, slow down and let them lead.

What should you look for during a pest walkthrough?

Look for visible conditions you can honestly point out, and stick to the areas connected to the homeowner’s concerns. Calvin Escobedo’s Bugs and Pests module has lessons on Outside the Home and The Yard, and those two areas are where most of a rep’s walk happens.

Where to look	What you might notice	A fair way to say it
Eaves and overhangs	Webs or small nests	“Here’s some webbing up here. Have you noticed more of it lately?”
Foundation and walkways	Ant trails or small soil mounds	“I can see some ant activity along here. Is this where you’ve been seeing them?”
Doors, windows and garage	Gaps or worn weatherstripping	“This gap is worth mentioning to the tech when they come out.”
Pipes and utility lines	Openings where lines enter the house	“The tech will want to take a look at where these lines come in.”
Plants and yard	Shrubs against the walls, stacked wood, damp spots	“These areas are worth pointing out to the technician on the first visit.”

Notice what is missing from that table: certainty. You are not announcing a diagnosis of the species, how bad it is or what it will do to the house. Say what you can see, then hand the rest to the technician.

How do you share what you found without scaring the homeowner?

Share what you found calmly, in plain words, and let the homeowner draw the conclusion. Point at the thing itself. “Here’s what I noticed” works better than any warning.

Fear is a bad sales tool in pest control. It erodes trust, it is easy to overdo, and it can quickly cross into deception. Keep these lines firm:

• Never fake evidence or exaggerate what you saw.
• Never tell someone they have an infestation unless a licensed professional has confirmed it.
• Never warn about health or property damage to push a sale.
• Never put down the company currently servicing the home.

If you see nothing, say that. “Honestly, the outside looks pretty good. You may not need anything from me right now, but here’s what ongoing service looks like if you ever want it.” Homeowners remember that sentence, and it often earns more trust than a hard pitch would. Read more in our guide to pest control sales ethics.

How do you set expectations after diagnosing a home?

Set expectations by telling the homeowner what you noticed, what the technician will check, what the service includes, and what it will not do. Calvin Escobedo has a lesson called Proper Diagnosis and Setting Expectations, and pairing those two in one title makes sense. A sale built on an accurate picture holds up after the first service.

Cover these points in your own words and your company’s approved language:

• The technician, not you, makes the call on identification and treatment.
• What the service covers, and what it does not.
• What the homeowner may see after service, and how your company handles follow-up visits.
• Who to call with questions.

Do not say “you’ll never see another bug,” and do not describe any product as safe, non-toxic or guaranteed. If the homeowner asks about children, pets or health, point them to the product label and the licensed technician. For help putting pest behavior into plain language, see how to explain pest problems to homeowners.

How do you move from the diagnosis to the close?

Move to the close by recapping what the homeowner told you and what you both saw, then recommending one plan. The recap does most of the selling, because every item on it came from them or from something they looked at with you.

It can sound like this: “So you’ve been seeing ants by the back door since spring, and we saw that activity along the patio. Based on that, here’s what I’d recommend.” Then present the plan and the price. If the walk uncovered something outside the base plan, the technician can review it, and you can note it for later.

From there, the rest of the sale is straightforward. Our guide on pest control closing techniques picks up at this exact moment.

Where do you learn to diagnose a home?

You learn to diagnose a home by getting the pest knowledge first, then practicing the conversation until the questions come naturally. Knowledge makes your questions better, and repetition keeps you from reverting to a feature list when you get nervous.

The Pest Pro Certification includes Bugs and Pests with Calvin Escobedo, Stages of a Pest Sale, and Pest Pro Tips – Marshall Hawkes. If you are newer, begin with the Pest Apprentice Certification and work your way up.

In the meantime, try this on your next ten doors: ask two more questions than you normally would before you mention your service. Then write down what you learned at each home. Your notes will show you which questions open people up, and which ones you can drop.

One last check before you rely on any of this in the field. Ask your manager what your company allows reps to do on a property and what you may say about what you see. Rules vary by state, and your company’s license and policies set your limits.
