A professional inspection is the most reliable way to find out whether you have bed bugs. Traps can warn you that something is there, but they cannot map an infestation. This guide explains what a survey generally involves in the UK, how to prepare, and what to ask before you book.

When an inspection makes sense

Start with what you have seen. If you find live bugs, shed skins, dark spots on the mattress or bites that keep appearing, our guide to the signs of bed bugs will help you judge how likely an infestation is. However, many things mimic bed bugs, so it is worth reading how to tell bed bugs from something else before you panic.

The NHS says bed bugs are hard to find and may resist some insecticides, so treating them yourself is very difficult. As a result, it advises you to contact your local council or a pest control service if you suspect them. An inspection is the sensible first step, because it confirms the insect before anyone sprays anything.

What a professional survey generally covers

Bed bug work is not guesswork. The British Pest Control Association (BPCA) publishes a code of best practice for its members, and it says a thorough survey must come before any treatment. The surveyor should check all areas of the property, especially resting places such as beds and sofas.

Expect the surveyor to look in places you would not think of. For example, the BPCA code notes that surveyors may need to open drawers and cupboards, remove headboards and lift carpet edges. Identifying the insect is critical. If the surveyor finds no evidence, the code says they must not use pesticides, although they may suggest a monitoring programme instead.

After the survey, the surveyor should tell you what they found and what needs to happen next. Because a full on-site survey is essential for a reliable quote, a sensible firm will not price a bed bug job properly without one. The BPCA code also says the firm must tell you about any survey charge before the visit.

How to prepare

First, ask what preparation the firm wants. The code says the firm must tell you about this at first contact. Then do the simple things well, because good access helps the surveyor see more.

  • Clear clutter from around beds and sofas.
  • Make sure every room is open and reachable.
  • Set aside bedding and clothes that the firm asks you to bag up for washing.
  • Keep a note of where you saw bites, bugs or marks.

It also helps to know your bed. If you plan to fit interceptors later, measure the legs of your bed in advance. However, do not rearrange the room just for the visit. Ask the firm what they would like you to do instead.

What to ask before you book

You are entitled to clear answers. Ask who will carry out the survey and whether they are trained for bed bug work. The BPCA code says anyone involved in bed bug control must be trained and competent. You can also ask whether the firm belongs to a trade body, and then check that claim yourself.

Next, ask what the quote will include. The code lists what a good quote should explain: what is covered, which rooms, how many visits may be needed, and what happens if control is not achieved. In addition, ask for the treatment plan in writing. If the firm mentions heat, ask whether they mean a genuine heat treatment or a steam generator, because the code treats them as different things. Our comparison of heat versus chemical treatment explains how the main options differ.

Finally, ask about guarantees only if you want them, and read the exact wording. We cannot promise any outcome, and neither can this page.

Where your local council fits in

The NHS suggests contacting your local council or a pest control service, and GOV.UK lets you find your council by postcode. Some councils offer pest control or refer residents to it. However, we cannot say what yours provides, so check its website to see what it offers.

If your council does not treat bed bugs, it may still point you to other help. In that case, you can use our enquiry form instead, as the last section explains.

Why traps help but do not replace an inspection

Monitors have a real job. Our guide to interceptors explains how they catch bugs climbing a bed leg. In the same way, sticky traps and active monitors can show activity in a room. Our page on what traps can and cannot do sets out the limits honestly.

The key point is that an empty trap does not prove your home is clear. A trap cannot tell you how far an infestation has spread or where the bugs hide. For that reason, use monitors alongside a survey, not instead of one. If you want help choosing, our best bed bug traps page compares what is sold on Amazon UK.

After treatment, monitoring becomes useful again. It shows whether activity continues, and our post on monitoring after bed bug treatment covers how to do it. You can also read how to use bed bug traps for placement basics.

Ask us to pass on your enquiry

If you would like a professional to look at your home, use the enquiry form. We pass your enquiry to a pest control professional covering your area. We are an independent comparison site, not a pest control company, and we do not set prices or promise outcomes. The professional will explain their own process, costs and terms directly to you.
