Why Waiting Until After Exams Is Tempting but Risky
The obvious plan is to put it off until the last paper. The trouble is that bedbugs do not wait: numbers build up week on week, bites get worse, and they can spread to a brother's or sister's room or to the sofa where the revising teenager falls asleep. A problem in one bedroom in spring can be a problem upstairs by summer.
Treating early, in a gap between papers or at a weekend, usually costs the student less time than months of poor sleep. Our guide on whether bedbugs bite every night explains why a few quiet nights do not mean they have gone.

Protecting Notes, Books and Laptops
Revision material is what students worry about first. Paper and books are not damaged by treatment, but how they are handled depends on the route:
- For heat, most books and papers can stay in the room and are treated with it. Laptops, tablets, chargers and some other electronics come out beforehand, along with aerosols and anything else on the list we give you.
- For chemical, desks and shelves are left in place, but the floor needs clearing. Notes in folders can be moved to a sealed plastic tub for the fortnight so they are not lost in the shuffle.
- Either way, check a school or college bag along its seams before it goes into another room, and keep revision on the desk, not on the bed.
Picking a Date That Works
Heat is usually one visit, with the student out of the room for most of a day and back in once it has cooled. That makes it easier to fit into a single gap between exams, and it costs more than chemical. The Redbridge heat treatment page describes how that day runs in a family house.
Chemical is an hour or two each visit and the room is usable again once dry, but there are usually two, sometimes three visits about 10 to 14 days apart. Plan the second one around the exam timetable as well as the first. The chemical treatment page sets out the course of visits.
Sleep and Study in the Meantime
Keep the student in their own bed until treatment. Moving them to a sibling's room or the sofa for a better night's sleep usually gives them a second room of bedbugs. Hot-wash and dry their bedding, keep the floor clear, and revise at a desk or kitchen table rather than on the bed.
If the bites are keeping them awake or look infected, a pharmacist or GP can help; call 999 for any sign of a severe allergic reaction. For households in South Woodford, telling us the exam dates when you ring helps us suggest a sensible day. If you are not sure it is bedbugs, an inspection confirms it first.
Bedbug Control South Woodford — Questions
Can my son or daughter revise in the room after treatment?
Yes, once it is ready. After heat that is when the room has cooled; after chemical, once surfaces are dry. Follow the instructions given on the day.
Will heat damage revision notes or textbooks?
Paper and books are normally fine in a heat treatment. Laptops, tablets and some other electronics come out first, and we give you the full list before the day.
Should we wait until the exams are over?
Usually not. Bedbugs build up and spread while you wait. Treating in a gap between papers normally costs the student less than weeks of broken sleep.
How much does treatment cost in South Woodford?
Treatments start from £220. The figure depends on how many rooms are involved and whether it is heat or chemical, and it is given on the phone before anything is booked.
Only my teenager is being bitten. Could the rest of the house be affected?
Possibly, since some people do not react. Check the other beds and the sofa for spotting along the seams. An inspection from £120 will tell you for certain.
