The Course, Not the Visit
Insecticide goes into the seams, bed frames, skirtings and gaps where bedbugs shelter. It does not reliably kill the eggs, so a second visit comes back once they have hatched, usually about ten to fourteen days later. Sometimes a third is needed. The London chemical treatment page has the full explanation of what is used and where.
What matters for you is that the first visit is the start, not the end. Bites in the week after it do not mean it has failed; young bugs are still hatching and walking across the treated surfaces. The course has done its job when the bites have stopped after the last visit, not after the first.
Each visit takes one to two hours in a typical flat, and you can use the rooms again once everything is dry.
Keeping the Flat Ready Between Visits
- Keep sleeping in your own bed. It feels wrong, but you are what draws the bugs out across the treated surfaces. Moving to the sofa or a relative’s flat tends to take them with you.
- Hot-wash and bag the bedding before each visit, and keep floors clear so we can reach every skirting.
- Do not scrub the edges. Normal cleaning is fine, but wiping down skirtings and bed frames between visits removes what was put there.
- Leave the mattress where it is unless we have told you to get rid of it. Carrying it down a shared stairwell is how the next flat gets them.
- Write down where and when you are bitten. It helps us decide on the spot whether a third visit is needed.

Council, Housing Association or Private Landlord
Estate flats in Havering are rented from the council, from a housing association or from a private landlord, and some are owned outright. Who arranges and pays for treatment depends on your tenancy and on how the bedbugs arrived. We are pest controllers, not legal advisers, so we cannot tell you who is liable. We can tell you what helps.
- Report it to your landlord in writing: email, an online repair form, or a letter you keep a copy of. Say what you have seen and when you first noticed it.
- Ask whether they will arrange treatment or want you to. Some landlords send their own contractor; if they do, let them in for every visit.
- If you arrange it yourself, tell the landlord who is coming and when, so nobody books a second firm on top of us.
- Keep the dates of every visit. If the problem carries on, a clear record of what was done is the first thing anybody asks for.
The Flats Either Side
In a block, the walls, floors and service ducts are shared. Treating your flat properly deals with your flat. It cannot deal with the one above or the one next door, and if bedbugs are living there too, they can walk back in along pipes and skirting.
That is one reason a landlord who owns several flats in a block may want neighbouring flats checked at the same time, and it is worth asking. Communal stairs and landings belong to the landlord, and only they can arrange for those to be looked at.
If you have been told your bites are not bedbugs but they carry on, read the Harold Hill page before anything is treated.

When Heat Is Worth Asking About
Some flats are better suited to heat: a bedroom packed with belongings, someone who cannot keep to a course of visits, or a household that needs it over in one day. Heat reaches the eggs in a single visit but costs more. The heat treatment page for Havering covers what that involves, and we can talk through both on the phone.
Price and Booking
Treatments start from £220, and chemical costs less than heat. The quote covers the full course of visits and depends on the number of rooms. Ring 0800 955 1018 and you get the figure on the phone before anything is booked. The Havering bedbug control page covers the rest of what we do in the borough.

Bedbug Chemical Treatment Havering — Questions
Why do I still get bites after the first visit?
Because eggs laid before treatment keep hatching. The young bugs cross the treated surfaces and die, which is why the second visit is booked about ten to fourteen days later.
What if I miss the second visit?
Ring and rebook as soon as you can. Leaving a long gap gives hatched bugs time to grow and lay eggs of their own, and the course has to catch up.
Will the council treat my flat?
It depends on your tenancy and the landlord’s own policy. Report it in writing and ask. We cannot tell you what they are obliged to do.
Can I stay at my sister's until it is over?
It is better not to. Sleeping elsewhere usually carries bedbugs to the next bed, and your empty room gives them no reason to come out across the treatment.
Do I need to tell my neighbours?
You do not have to, but in a block it helps. If they have bites too, both flats need treating, or the problem keeps moving between them.
Is it all right for the children to go back in the room?
Once the treated surfaces are dry, the room can be used again. Follow the instructions we give you on the day about the bed and the edges.
