Why Chemical Treatment Fits an Estate Flat
The flats on the big estates in Roehampton and Battersea are usually compact, with modern walls, fitted skirtings and fewer hiding places than an old house. A residual insecticide worked into seams, frames, skirting edges and the gaps where fittings meet the wall reaches most of what matters in rooms like these, and it keeps working at the edges for bedbugs that arrive later from a neighbouring flat.
How the product works, and why it misses the eggs on the first pass, is covered on the London chemical treatment page, for the full explanation. Here we cover the estate side.
The Two Visits, and Keeping Them
Because the first visit does not reliably kill eggs, a second visit about 10 to 14 days later deals with the bugs that have hatched in between, and sometimes a third is needed. Each visit takes one to two hours. On an estate, the thing most likely to spoil this is not the treatment but the diary: a missed second appointment, a changed shift, or nobody home to let us in.
- Book both dates at the first call, so the gap is right and you can plan round them.
- If someone else has the keys on the day, make sure the entry phone, the block door and the flat door are all covered.
- Strip and hot-wash the bedding before each visit, and clear the floors so the skirtings can be reached.
- Keep everyone out of the treated rooms until the surfaces are dry, then use them as normal.
- Do not vacuum or wash down the skirtings between visits; the product there is doing its job.

Who Else Needs to Know
If you rent from the council or a housing association, your tenancy decides who arranges and pays for pest control, and that can depend on how the problem started. Report it in writing, keep a copy, and note the date. We are pest controllers, not legal advisers, so we cannot tell you what your landlord owes you, but we can treat once you know who is booking.
If your landlord wants to send their own contractor, the Balham page covers how to handle that. If you are about to move to a new flat within a regeneration scheme, read the Roehampton page first, because the move itself needs planning.
Neighbours matter more on an estate than anywhere else. A flat next door, above or below, with the same problem will keep feeding bugs back through service ducts and gaps round pipes. You do not have to knock on every door, but if a neighbour mentions bites, suggest they report it too. If you have seen bugs only since the flat below was treated, the Battersea page explains what that usually means.
Shared Spaces on the Estate
Landings, lifts, stairwells and bin rooms are not where bedbugs live, because nobody sleeps there. What does travel through them is furniture. A mattress or sofa left on a landing for collection can carry bugs to whoever picks it up, so if you are getting rid of anything, wrap it, mark it and arrange collection rather than leaving it out. Do not throw out your own bed before treatment unless we tell you to; moving it through the block spreads them.
Community rooms and any shared seating on the estate are a matter for whoever manages the building. If you have noticed something there, tell the housing officer.

When Chemical Is Not the Right Answer
If the problem has spread through every room of a crowded flat, or you cannot manage two or three visits, heat treatment in Wandsworth may be worth the higher price. If a family member is pregnant, has a young baby, or has breathing problems, tell us when you book so we can talk through the approach, and follow the instructions given on the day.
If you are not sure what you have found, an inspection confirms it before anyone spends money.
Cost
Treatments start from £220, and chemical costs less than heat. The price covers the course of visits for the rooms involved, and the exact figure depends on how many rooms need treating. Ring 0800 955 1018 and you get it on the phone before anything is booked. The Wandsworth bedbug control page covers the other building types in the borough.

Bedbug Chemical Treatment Wandsworth — Questions
Does the whole block need treating if my flat has bedbugs?
Not automatically. We treat the flats that have signs. If neighbours report bites too, those flats need attention as well, and that is usually arranged through the landlord or housing officer.
Why do I need a second visit if I have not seen any more bugs?
Eggs laid before the first visit hatch afterwards. The second visit catches that generation before it can breed, even if you have not spotted it yet.
Can I stay in the flat between visits?
Yes. Once the treated surfaces are dry you use the rooms and sleep in your own bed as normal. Sleeping somewhere else usually spreads them.
Should I tell my housing officer before you come?
If you rent, report it in writing to your landlord or housing officer either way. Who arranges and pays depends on your tenancy, and it is better that is settled before the first visit.
What if I miss the second appointment?
Ring as soon as you know and we will rebook it as close to the right gap as we can. Leaving it weeks gives the young bugs time to grow and lay.
