The Things That Make It Worse
Most of the damage done while people wait comes from trying hard. Each of these feels like progress and usually is not:
- Moving to the sofa or another bedroom, which gives them a second room
- Shop-bought foggers and bug bombs, which drive bedbugs deeper into walls and next door without reaching the eggs
- Dragging the mattress or bed out to the bins before anyone has looked at it
- Emptying drawers and wardrobes into bags that then sit in the hall
- Moving furniture around to “get at” them

What Genuinely Helps
- Keep sleeping in your own bed. It keeps them in one place, which is what the treatment will need.
- Wash bedding hot every few days. Strip it in the room, bag it, and put it straight into the machine and then the dryer.
- Pull the bed a little away from the wall and keep the covers off the floor, so there are fewer easy routes onto it.
- Clear the floor gradually. Anything stored under the bed or around the edges of the room will have to be cleared anyway, so wash, dry and bag it now rather than all on the morning of the visit.
- Vacuum carefully along the mattress seams and skirtings, then seal the bag or empty the canister into a tied bag and put it in an outside bin.
Keep the Landlord in the Loop
Put your report in writing if you have not already, and write again if things change: bites in another room, spotting on the sofa, a neighbour mentioning the same thing. Keep the replies. If the date slips, ask for the new one in writing too. Who arranges and pays depends on the tenancy and the cause, and we are not legal advisers, but a clear record helps everyone later.
Most landlord bookings in rented flats are for chemical treatment, which means two or three visits. Ask whether the booking covers the follow-up, and whether the rooms next door are being looked at. If you want an independent answer on what is there before the date, an inspection starts at £120.
Getting Ready for the Visit
The last few days before treatment are about access. Floors clear along every wall of the affected room, bedding washed and bagged, furniture left where it stands, and pets and anyone vulnerable out of the room for the visit. Follow the instructions you are given on the day about when to go back in.
If you want to know roughly how the weeks ahead will go, the timeline from first bite to all clear walks through it. Wider advice for households across Merton is on the borough page. And if the wait in Mitcham turns into months, ring us and we will tell you what a private treatment would involve.
Bites vary. Some people react badly and some not at all. A pharmacist or GP can help with itching and skin reactions; call 999 for any sign of a severe allergic reaction.
Bedbug Control Mitcham — Questions
Can I pay for my own treatment instead of waiting?
You can, but tell the landlord in writing first so the two do not clash. Treatments start at £220, and you get the figure before anything is booked.
Is it worth using a spray from the shop in the meantime?
We would not. Shop sprays and foggers tend to scatter bedbugs into other rooms and neighbouring flats without touching the eggs.
Should I throw my mattress out while I wait?
No. Carrying it out spreads them, and a new mattress in the same room will soon have them. Wait for the treatment.
Will a few weeks make it much worse?
It can grow in that time, which is why keeping them in one room matters. The steps above keep it as contained as it can be until the Mitcham visit.
