Bedbugs live indoors, so they do not have a season in the way that wasps or mosquitoes do. What they do have is a pace, and that pace follows the warmth of the room they are in. Add the travel and visitors that come with summer and it is easy to see why the calls pick up then.
Warmth Speeds Them Up
In a warm room, bedbugs feed more often, eggs hatch sooner and the young grow into adults faster. A small problem that would have crept along through a cool spring can build up noticeably over a few warm weeks. None of that makes the individual insects more dangerous; it just means there are more of them sooner.
Homes that stay warm all year, with good heating, thick walls or a top-floor flat under the roof, may not see much seasonal change at all. The pace in those rooms is steady.
Holidays, Guests and Luggage
The other reason is movement. Summer means holidays, hotel rooms, holiday lets and overnight trains, and it means visitors staying with you. Every suitcase that has been somewhere people sleep is a possible lift for a bedbug.
- On arrival anywhere, keep the case on a rack or a hard floor and look at the mattress seams.
- At home, unpack away from the bedroom, and put holiday clothes through a hot wash and dryer.
- Vacuum the seams and pockets of the case, then store it outside the bedroom.
- Give guests somewhere other than a bed to put their bags.
The borough sees plenty of visitors and short stays, and hotels have their own routines for this; see the Kensington and Chelsea hotel treatment page if you run one.
Why Winter Is Not a Cure

People sometimes hope a cold snap will deal with the problem, or that it will fade on its own after the summer. It will not. Indoors, next to a heated bed, bedbugs slow down in cooler months but carry on. Opening windows or turning the heating off does not bring a bedroom anywhere near cold enough, and a cold spell outside does not reach into a mattress or a wardrobe.
A quieter winter can actually make things worse, because fewer bites mean people put off dealing with it, and the problem is larger by the next spring. If you have seen signs, treat when you find them, whatever the month.
When People Tend to Notice
Summer is also the season of lighter bedding and bare skin. Arms and legs outside the covers get bitten more visibly, and pale sheets show spotting that a winter duvet hides. So a problem that started months ago can seem to appear suddenly in July.
Bites alone are not proof. Mosquitoes, fleas and other insects are busier in warm weather too, and people react very differently. Look for the signs in the bed itself; our London guide to the early signs of bedbugs shows what to look for. If you are not sure, an inspection from £120 answers it.
Does the Season Change the Treatment?
Not much. Heat treatment raises the room to a temperature bedbugs cannot survive whatever the weather outside, and a thermal camera checks for cold spots. Chemical treatment is the same course of visits in any month. The practical difference is planning: in summer, book treatment around holidays so that nobody packs from an affected bedroom mid-course.
Treatments start from £220, with the figure set by the rooms and the method. The Kensington and Chelsea bedbug page covers what stays in the room and what has to come out first.

Related Questions
Do bedbugs die off in winter?
No. Indoors they slow down in cooler months but survive, and they pick up again when it is warmer.
Should I wait until after my holiday to get treatment?
Better to plan it before, or at least not to pack from an affected bedroom. Otherwise you can take them away with you and bring them back.
Can I open the windows in winter to freeze them out?
It will not get a bedroom anywhere near cold enough, and bedbugs deep in a mattress or a frame are well insulated.
Is heat treatment harder in hot weather?
No. The room is brought to a temperature bedbugs cannot survive regardless of the season, and it is checked with a thermal camera.
