In short

What is pest inspection?

A general pest inspection is a walk of the whole property looking for evidence of pests, the entry points letting them in, and the conditions keeping them there — then a written report of what was found and where. It is broader than a termite inspection and produces no lender document. Its value depends almost entirely on one thing: whether the person inspecting also sells the treatment they are about to recommend.

Triggers

Signs you need pest inspection

You are hearing something in the ceiling or the wall at night and cannot tell what it is
You have found droppings, gnaw marks or a smell and want an identification before you act
You keep seeing insects with no obvious source, in a room with no obvious food
Your general home inspector flagged something pest-related and moved on
You have treated the same problem twice and it has come back both times — a sign the entry point was never found
You just moved in and want a baseline before you commit to a service plan
You are a landlord getting conflicting reports from a tenant and need something documented

The job

How pest inspection actually works

You describe the evidence first

Where, when, how often, and what you actually saw or heard. Scratching in the ceiling at dusk points somewhere completely different from a trail of insects on the kitchen counter at night.

Watch for: An inspector who does not ask. The homeowner's observations narrow the search more than anything else on this list.
Exterior walk and entry-point survey

The perimeter, the grade line, utility and pipe penetrations, weep holes, vents, soffits, the roofline, the garage door seal, and vegetation touching the building. This is where the actual cause almost always is.

Watch for: An inspection that never leaves the inside of the house. Interior sightings are symptoms; the entry point is the diagnosis.
Interior inspection of the likely harbourage

Under sinks and appliances, the water heater closet, pantry, behind and beneath cabinetry, plumbing chases, and any area you reported activity in.

Watch for: Nobody moving anything. Most interior evidence sits behind or beneath something.
Attic, crawl space and basement

Insulation disturbance, droppings, rub marks along joists, chewed wiring, nesting material, moisture, and daylight visible at eaves or vents. These spaces produce most of the meaningful findings in a house.

Watch for: Both spaces skipped. If the attic hatch was not opened and the crawl space not entered, the inspection covered the least informative part of the building.
The findings report

What was found, where specifically, what it indicates, and what conditions are supporting it — ideally with photographs of anything you cannot see for yourself.

Watch for: A report that is a treatment proposal with a findings paragraph on top. Those are different documents and you should be able to tell which one you were given.

Money

What does pest inspection cost?

Independent pest inspections are usually a modest flat fee, scaled by property size and how much crawl space and attic work is involved. Treatment companies commonly inspect free, which trades the fee for a sales conversation. See the Cost Guide for how inspection fees are often credited against later work.

Straight answer

When pest inspection is the wrong call

Everyone else ranking for this is paid when you say yes. Here's when you shouldn't.

You need a document for a property transaction. A general pest inspection is not a wood-destroying insect report and no lender will accept it as one. If a closing depends on it, order the WDI report instead.
You already know exactly what you have and where. A visible wasp nest under the eave or a mouse caught in the kitchen does not need diagnosing. Go straight to quotes for the job.
You are about to buy a service plan anyway. Every reputable plan starts with an inspection included. Paying separately first duplicates it — unless you specifically want that inspection to come from someone who is not selling you the plan.
You want it to cover structure, mould or moisture. An inspector may note damp or damage as a conducive condition, but assessing it is a different trade. Do not treat a pest report as a building survey.
The activity is seasonal and predictable. Cluster flies at one window each autumn or a few spiders in the garage in September are normal building behaviour, not a case for a paid diagnostic.

Before you sign

What to check when hiring for pest inspection

Do you sell treatment as well as inspection?

The central question on this page. A free inspection from a treatment company is a real service and often a competent one — it is simply also a sales call, and the recommendation should be read that way.
Will you enter the attic and the crawl space?

These produce most of the findings. If the answer is "if accessible", find out now what would make them inaccessible and clear it before the visit.
What will I receive in writing, and does it include photographs?

Photographs of a crawl space you will never enter are the difference between a report you can act on and one you have to take on faith.
Will the report identify species, not just "rodents" or "insects"?

Treatment differs sharply within those groups — mice and rats need different exclusion, German and American cockroaches need different approaches. A report without identification cannot be costed properly.
Is the inspection fee credited if I go on to book treatment?

Frequently yes, which makes an independent paid inspection cheaper than it first appears. Ask before booking, not after.
Will you list entry points and conducive conditions separately from pest findings?

The entry points are the part you can act on without buying anything. Kept separate, that list is usually the most valuable page of the report.

FAQ

Pest Inspection — questions people ask

Still have a question? Talk to our team →

Is a free pest inspection worth having?

Often yes — technicians doing them are usually experienced and will spot things you would not. The limitation is structural, not personal: the visit exists to produce a proposal, so it is oriented toward what the company sells. Take the free inspection for the identification, then treat the recommendation as a bid rather than a diagnosis, and get a second one before committing to anything expensive.

What is the difference between this and a termite inspection?

A termite or WDI inspection has a narrow scope — wood-destroying insects — and produces a standard form used in property transactions. A general pest inspection has a wide scope and produces a findings report for you. Neither substitutes for the other, and buying one when you needed the other is a common mistake, usually discovered at the worst point in a closing.

How long should it take?

For an average single-family home with a crawl space or an accessible attic, an hour or more is realistic. Twenty minutes means someone walked the interior and looked under a sink. Duration is not a quality guarantee, but an unusually short visit on a complicated house tells you what was skipped.

What should I do before the inspector arrives?

Clear the attic hatch and crawl space access, unlock gates, move stored items away from garage and basement walls, clear under-sink cabinets, and write down every sighting with a place and a time. Do not clean up the droppings — that is the evidence, and photographing it before the visit is genuinely useful if it has been intermittent.

Will the report tell me what treatment I need?

A good one tells you what was found, what it indicates, and what the realistic options are — including which of them you can do yourself. Be more sceptical of a report that names a single recommended package with a price at the bottom and no alternatives discussed, because that is a proposal wearing a report's clothes.
