Whose Problem Is It?
In a furnished let the mattress, bed frame and upholstered chairs are the landlord's property. If the bedbugs were there before you arrived, that usually points towards the landlord or the letting agent arranging treatment. If they arrived later, in your own luggage, it can point the other way. Most tenancies say something about pests, and a company relocation package may say something too.
We are pest controllers, not legal advisers, so we will not tell you who has to pay. What we can say is that the order of events matters. Report it in writing to the agent or landlord as soon as you are sure, keep a copy, and photograph what you found: the spotting on a seam, a live insect in a clear bag, the date. If your employer arranged the flat, copy in whoever handles the relocation.

Making Sure It Really Is Bedbugs
A landlord is more likely to act quickly on a confirmed finding than on a description of bites. An inspection starts from £120 and gives everyone the same answer: whether bedbugs are present, which rooms are involved and which pieces of furniture are carrying them. If it turns out to be something else, you have spent far less than a treatment.
Please do not drag the mattress out to the bins or ask the agent to swap it before anyone has looked. Carrying an infested mattress down a stairwell sheds insects on the way, and a new one dropped into the same room simply gets moved into.
Treatment in a Flat That Is Not Yours
Either route can work. Heat treatment suits a furnished let where the tenancy is short, because it deals with the eggs too and is usually one visit, so the flat is not tied up for a fortnight while you wait for a follow-up. Chemical treatment costs less and is usually two or three visits about 10 to 14 days apart, which works if you are staying on for a while. Whoever books it, the exact figure is given on the phone once we know how many rooms are involved.
Your part is the same either way: your own clothes and bedding washed hot and bagged, your suitcases open and ready to be looked at, and the floor clear. You do not need to move the landlord's furniture.
Leaving Without Them
The risk for someone relocating is carrying bedbugs from the temporary flat into the place you settle in next. In the weeks before you go, keep packed bags zipped and off the bedroom floor, wash every fabric item on the hottest setting it can take before it goes into a box, and check the seams of your cases on the day you leave. If the flat has not been treated by then, be stricter still: unpack at the new place on a hard floor, one bag at a time, and check each item as it comes out.
If you were bitten on a trip before you moved in, our guide to holiday cottages, campsites and B&Bs covers checking your things after a stay away. The Richmond borough page is about stopping bedbugs coming back once a home has been treated.
Bedbug Control Richmond Town Centre — Questions
Can I just move out early?
That depends on your tenancy, which is a question for the agent or an adviser, not us. From a pest point of view, leaving early does not help if your belongings go with you untreated.
The agent wants me to pay. Can you settle who is responsible?
No. Who arranges and pays depends on the tenancy and on where the bedbugs came from. We can tell you what we find at an inspection, which is often what both sides need first.
Will my relocation company accept your quote?
We give the figure on the phone before anything is booked, based on the rooms and the treatment. Whether a relocation budget covers it is between you and your employer.
Should I throw away my own mattress topper?
Not before we have looked. Bag it and leave it in the room. Most fabric items can be dealt with by washing or by treatment, and moving it spreads them.
Can I stay in the flat during treatment?
You stay out of the room while we work. After chemical treatment you are back in once surfaces are dry; after heat, once the room has cooled. Follow the instructions given on the day.
