What the Course Looks Like on a Calendar
Put the first visit in the diary, then pencil in a second one about ten to fourteen days later and keep a third date free after that in case it is needed. Each visit takes one to two hours. Between them, the household lives in the house normally, apart from a few habits in the treated room.
The gap matters because the insecticide does not reliably kill eggs, so the later visits catch the young bedbugs that hatch in between. Why that is, and where the product goes, is on the London chemical treatment page for the full explanation. If you want to know what the young ones look like when you check the bed, see how to recognise bedbug nymphs.
Tell Us Who Lives in the House
When you ring, tell us about everybody who uses the room and the rooms next to it: a baby who naps in a cot in your bedroom, a toddler who crawls, someone who is pregnant, someone recovering from an illness, someone who needs help getting in and out of bed. None of that is a reason to refuse the work. It changes how we plan the visits and what we ask you to do.
If anyone in the house has asthma or another breathing condition, the Greenford page goes through choosing a treatment with that in mind and what to tell us. If you have a medical question about your own situation, ask your GP or pharmacist as well.

Planning Each Visit Around Little Ones
Nobody except the technician should be in the room while it is treated, and people and pets stay out until the treated surfaces are dry. With small children, that is easiest if they are out of the house altogether for the visit and the drying time. Ways families manage it:
- Book the visit for a nursery or school morning, or when a grandparent can take the children out.
- Move the cot, changing mat and night-time things for the baby to another room the evening before.
- Close the door of the treated room and keep it closed until we say the room can be used.
- Keep toddlers off the floor edges and skirtings in that room until you have been told it is dry.
- Follow exactly what the technician tells you on the day about when the room can be used again.
A child’s cuddly toys need dealing with before the first visit, not after. Our guide to soft toys covers washing, drying and the one toy that cannot go in the machine.
The Evening Before a Visit
The preparation is the same before every visit and happens only in the affected room. Strip the beds and hot-wash everything that can be washed, then bag it and keep it sealed. Clear the floor so the technician can reach the skirtings, and leave the furniture where it stands. If the house is busy and one evening feels impossible, the Perivale page sets out what to do first when time is short.
When the person who is unwell sleeps in the affected room, plan where they will rest during the visit and the drying time. A chair downstairs with a blanket from the bagged, washed pile is fine. Moving them to sleep in another bed for weeks is not, because that is how a second room gets involved.
Between Visits
Keep sleeping in the treated room. The residue works on bedbugs that come out to feed, so an empty bed slows the course down. Do not vacuum or wipe the skirtings and bed frame unless we tell you to, and do not add a shop spray on top. Bites can carry on for a while; that is expected in the first fortnight and is not a sign the work has failed.
For skin reactions, a pharmacist or GP is the right person to ask. Bites vary, and some people do not react at all. Signs of a severe allergic reaction need 999.
When Heat Is the Better Fit
If the household cannot keep children out of the room for each drying time, or cannot manage two or three visits over a month, heat may suit you better even though it costs more. It is usually one visit, most of a day, with the rooms back once cooled. The heat treatment page for Ealing covers that day in a family house.
Treatments start from £220, and chemical is the lower-cost route. Ring 0800 955 1018, tell us how many rooms are affected and who lives there, and you will have the figure on the phone before anything is booked.

Bedbug Chemical Treatment Ealing — Questions
Can my baby sleep in the room after chemical treatment?
Not until the treated surfaces are dry and the technician has told you the room can be used. Follow the instructions given on the day, and ask them anything you are unsure about before they leave.
Do we all have to leave the house during a visit?
Only the treated room has to be empty of people and pets, until it is dry. With small children, most families find it easier to take them out for the visit.
Why can we not just use the spare room until it is over?
Because bedbugs follow people to a new bed, and the spare room then needs treating too. Keep sleeping in your usual bed so the residue does its work.
How many visits will we need?
Usually two, sometimes three, about ten to fourteen days apart. Each takes one to two hours.
Should I tell you about a health condition in the house?
Yes, always. It helps us plan the visits. For medical questions about yourself or a family member, ask your GP or pharmacist.
How much does chemical treatment cost?
Treatments start from £220, and chemical costs less than heat. The exact figure depends on the number of rooms and is given on the phone.
