Bedbug Chemical Treatment Merton

A Course, Not a Visit

Residual insecticide kills bugs that walk across it, but it cannot be relied on to kill eggs. So the first visit deals with what is active, and the second, about ten to fourteen days later, catches what has hatched in between. If live bugs are still found at the second visit, a third follows on the same spacing. The London chemical treatment page has the full explanation of how the product works.

What matters in a flat is that the course is not broken. A missed second visit leaves the next generation to breed, and you are back where you started with the first visit paid for.

Who Arranges It: You or the Landlord

If you rent from the council or a housing association, or from a private landlord, report the problem in writing first and keep a copy. Whether the landlord arranges and pays for treatment depends on your tenancy and on how the bedbugs arrived, and we are pest controllers, not legal advisers, so we cannot settle that for you.

• If the landlord books its own contractor, the course still looks much as described here. Ask for the dates of both visits in writing when the first is booked.
• If you are asked to arrange it yourself, ring us. We quote on the rooms involved and you can pass the quote to the landlord if they have agreed to reimburse you.
• If you own the flat, the choice is yours, but tell the managing agent. Bedbugs in one flat are a reason for the neighbours to check theirs.

If the landlord’s date is some weeks off, the Mitcham page covers how to manage until then. If you are part-way through a home swap, the Morden page deals with that.

Being In and Being Ready for Each Visit

In a block, access is where courses tend to slip. Somebody needs to be in to let the technician into the flat, and the flat needs to be ready when they arrive. Each visit takes one to two hours.

1. Put both visit dates on the calendar the day the first is booked, and tell anyone else who holds a key.
2. The night before, strip every affected bed and hot-wash the bedding; carry it to the machine in a bag.
3. Clear the floors of the treated rooms, including under the beds, so skirtings and frames can be reached.
4. Leave furniture where it stands, and do not drag a bed or sofa out onto the landing or balcony.
5. Tell us about anyone who is pregnant or has a breathing condition, and about fish or birds, before the visit.
6. Keep everyone, pets included, out of the treated rooms until the surfaces are dry, and follow the instructions the technician gives you on the day.

If you cannot be in on a booked date, ring as soon as you know. Moving a visit by a day or two is far better than losing it.

Between Visits in a Flat

Keep sleeping in your own bed. It feels wrong, but the person in the bed draws the bugs across the treated surfaces; sleeping on a relative’s sofa or in the next room tends to take them with you. Do not use shop sprays or foggers, which can push bugs through gaps into the flat next door. Vacuum the middle of floors if you need to, but leave the skirting edges alone.

In a block, bugs can move between flats along service routes, and bedbugs behind radiators and pipes explains which gaps to look at. If a neighbour mentions bites, suggest they report it too; treating one flat while the next is untouched is a weak position.

Keeping a Record

Write down the date you first saw signs, the date you reported it, the visit dates and anything you see between visits: a live bug by the skirting, new bites, fresh spotting. It helps the technician judge whether a third visit is needed, and it helps you if there is any disagreement with the landlord later. The bedbug timeline shows what is normal at each stage.

When Chemical Is Not the Right Fit

If the flat cannot be kept to a course of visits, or several rooms are involved and preparation for each visit is too much for the household, heat may suit better. The heat treatment page for Merton describes that route, which usually takes one visit and costs more.

Treatments start from £220, and chemical is the lower-cost route. The figure depends on the number of rooms and is given on 0800 955 1018 before anything is booked. The Merton bedbug control page has the wider picture.
