Starting the Conversation
Nobody likes being told their room has bedbugs, and a young person far from home may assume they are about to lose the room or be accused of something. Say plainly that bedbugs arrive on luggage, clothes and furniture, that they have nothing to do with how clean someone is, and that you are dealing with it together.
Where English is a second language, keep it simple and put the main points in writing so they can read them again or run them through a translator. A short list works better than a long message: what has been found, what happens next, and what you need them to do.
Do not try to work out where they came from before the room is treated. It rarely changes the job, and it can sour a lodging arrangement that was going well. If the question of who pays comes up, that depends on your agreement with the student; we are pest controllers, not legal advisers.

What Your Lodger Needs to Do
- Carry on sleeping in their own bed. A night on a friend’s floor or in your living room tends to take bedbugs somewhere new. Getting through the nights before treatment has practical tips.
- Wash and bag clothes from the room. Hot wash what can take it, tumble dry the rest on high, and keep the clean things sealed until the room is done.
- Leave the suitcase where it is. Cases stored under the bed are one of the first places we check, so do not move them to a cupboard elsewhere in the house.
- Keep medicines, sprays and electronics together. If the room is treated with heat, those come out first, and it is quicker if they are already in one bag.
Choosing How to Treat a Lodger’s Room
A single bedroom that nobody else sleeps in often suits chemical treatment. It costs less than heat, but it usually needs a second visit and sometimes a third, about 10–14 days apart, and the student has to be around to strip the bed and clear the floor each time. That can clash with lectures or a trip home.
Heat treatment is usually one visit, costs more, and kills the eggs as well, so the room is finished in a single day. Many hosts in Harrow Town Centre choose it when term is about to end or a new student is due. Either way, the figure is given on the phone before anything is booked, and treatments start at £220.
Before the Next Student Arrives
Once the lodger’s room in Harrow Town Centre is clear, look at the mattress seams and the bed frame joints a couple of times in the first month. If you host students regularly, ask each new one to unpack onto a hard floor rather than the bed. For a wider view of family homes across the borough, see the Harrow borough page.
Bedbug Control Harrow Town Centre — Questions
Should I ask my lodger to leave until the room is treated?
No. Moving them out usually spreads the problem into wherever they go next, including other rooms in your house. Treat the room with them still living in it.
My student has bites but says they are mosquito bites. What do I do?
Bites alone do not prove anything, because people react differently and some not at all. Look for spotting on the mattress seams, or book an inspection, which starts from £120 in Harrow Town Centre.
Do I need to tell the student's college or agency?
That depends on your arrangement with them. There is no pest control reason to, but some hosting schemes ask to be kept informed.
Can you explain the preparation to my lodger directly?
Yes. Put them on the phone when you ring, or pass on the list we give you. Hearing it from us sometimes helps a nervous student.
Will the rest of the house need treating?
Not usually, if the bedbugs are confined to the lodger’s room. We check the rooms next to it and the living areas they use before we decide.
