What a professional inspection is
A visual inspection carried out by a licensed technician, working systematically through the areas where bed bugs harbour and feed. The output should be a clear statement of what was found, where, and what it means for treatment.
Areas commonly checked
- Mattress seams, piping and labels
- Box springs and their fabric underside
- Bed frames, slats, screw holes and joints
- Headboards, including behind them where fixed to the wall
- Nightstands, dressers and upholstered furniture
- Baseboards, carpet edges, cracks and crevices
- Wall fittings, switch plates and picture frames where activity is heavy
- Adjacent rooms or units where movement is plausible
Evidence professionals look for
Any one of these may indicate bed bugs. Interpretation matters, which is why a professional confirmation is more reliable than a photo comparison.
- Live insects at various life stages
- Dark, ink-like spotting on fabric and wood
- Shed skins in seams and crevices
- Eggs and eggshells, which are very small and pale
- Rusty smears on sheets consistent with crushed insects
When canine inspections may be used
Some companies offer scent-detection dogs, most often in large properties, hotels or multi-unit buildings where visual inspection of every room is impractical. Results depend heavily on the handler and the team's training, and reputable operators confirm an alert visually before treating.
Free versus paid inspections
| Type | Typically involves | What to clarify |
|---|---|---|
| Free inspection | A quoting visit that checks the main affected areas | How thorough it is, and whether adjacent rooms are included |
| Paid inspection | A longer, documented inspection, sometimes with a written report | Whether the fee is credited against treatment |
What to expect afterwards
You should leave the visit knowing whether activity was confirmed, which areas are affected, what method is being recommended and why, what preparation would be required, and how many visits the program includes.
How to prepare for an inspection
- Do not spray retail products beforehand — it can scatter insects and complicate the assessment
- Leave bedding in place unless asked otherwise
- Note where and when you have seen bites, spotting or insects
- Provide access to all rooms, including storage and adjoining spaces
Frequently asked questions
Can an inspection confirm bed bugs from bites alone?
No. Bites vary between people and can be consistent with other causes. Physical evidence such as live insects, skins, eggs or spotting is what confirms an infestation.
How long does an inspection take?
It depends on the property size and how many rooms are involved. A single bedroom is quick; a multi-room home or a unit in a shared building takes longer.
