Britain is in the most active stretch of the bed bug year. Monitoring firm Valpas found bed bugs in one in every 42 hotel rooms it observed, and cases in London are rising about 20% a year. According to Western Morning News on October 14, 2026, experts say the UK has reached "peak bedbug" season.
Three numbers that show the rise
- 1 in 42: of the hotel rooms Valpas monitored, one in 42 had bed bugs (cited from The Times).
- ~20% a year: bed bug cases in London and other big European cities are rising about a fifth each year (Valpas).
- Up 40%: one London borough tackled 40% more bed bug infestations this year than in the same period in 2025 (reported by Metro).
Note: these are Valpas monitoring figures (bugs actually detected), not the separate Valpas–Phocuswright traveller-worry survey (what travellers fear). The two are different datasets — don't mix them.
Why the rise: resistance plus travel
- Insecticide resistance: London pest experts say resistance is clearly growing, concentrated in London; some firms now offer only heat treatments, because bed bugs cannot survive high heat.
- Travel movement: public transport gives bed bugs chances to move with people — thousands use the same seating and storage areas, and a passenger can unknowingly carry a bug onto a train or aircraft in luggage, where it hides in a seat seam and gets picked up by someone else.
- Experts stress, though, that finding bed bugs on public transport is still very uncommon; hotels and holiday rentals remain the main spread points.
What the experts say
- James Rhoades of ThermoPest: heat treatments warm entire rooms above 50°C and hold that temperature for hours — at that temperature, nothing survives.
- Exterminator Abhi Nav: many DIY treatments fail because bed bugs can survive months without feeding; surface sprays rarely work. Proper inspection plus multi-step treatment with follow-ups matters.
- In the same week, a Qantas aircraft and two Southeastern train driver carriages also made bed bug news (nothing was found in passenger areas on the trains; an isolated incident, since cleaned). That shows bed bugs are now a cross-transport story — but this article doesn't re-report those incidents; the focus is the UK trend.
What it means for Hong Kong travellers
- Autumn–winter travel peak: Christmas and New Year trips to Europe put hotels at the top of the risk list. Don't assume an expensive hotel is safe — the monitoring data says one room in 42 is hit.
- Don't judge by cleanliness: bed bugs are not a sign of dirt. What matters is whether they were carried in on luggage or clothing.
- The first ten minutes in the room matter most: check mattress edges and seams, under the pillows, behind the headboard; keep luggage off the bed and carpet; if you spot anything suspicious, tell the hotel at once and ask for a room change plus a written record.
- Getting home is the key moment: don't carry luggage into the bedroom; wash and heat-dry all clothing right away.
