Another week, another bed bug warning. As highlighted by the Bournemouth Echo, UK homeowners are being urged to check their properties for bed bugs as infestations continue to rise across the country. The warnings are becoming more frequent — and for good reason.
Bed bug cases have been trending upward since the Paris outbreak made global headlines in late 2023, and UK pest controllers are reporting sustained increases in callouts through 2025 and into 2026. This is not a blip. It is a structural shift in bed bug prevalence, driven by travel, pesticide resistance, and the second-hand furniture market.
How to Check Your Home
Bed bugs are masters of concealment. They are flat, about the size of an apple seed, and hide in crevices during the day. Here is what to look for:
- Mattress seams: Run your finger along the piping and seams of your mattress, especially at the corners. Look for tiny black dots (excrement), pale shed skins, or the reddish-brown bugs themselves.
- Headboard: If your headboard is attached to the wall, pull it forward and check the back. Bed bugs love the gap between headboard and wall.
- Bed frame joints: Check screw holes, dowel joints, and any cracks in wooden bed frames. Use a torch and a thin piece of card to probe into tight spaces.
- Bedside furniture: Inside drawers, behind bedside tables, and along the edges of fitted wardrobes near the bed.
- Blood spots on sheets: Small spots of blood from bites or crushed bugs are an early warning sign.

Why DIY Treatment Often Fails
Here is something the articles warning about bed bugs rarely mention: most DIY bed bug treatments have a poor success rate. There are several reasons:
- Pesticide resistance: Many bed bug populations in the UK have developed resistance to pyrethroid insecticides — the active ingredient in most off-the-shelf bed bug spray products. The sprays may kill some bugs on contact but fail to eliminate the colony.
- Egg survival: Bed bug eggs are resistant to most contact sprays. Even if you kill every adult, unhatched eggs will produce a new generation within 7–10 days.
- Hidden harbourage: Bed bugs hide in places sprays cannot reach — inside wall sockets, behind skirting boards, in the seams of curtains. A surface spray will not touch them.
- Insufficient coverage: Effective treatment requires treating every harbourage point, not just the mattress. Most DIY attempts under-treat, leaving survivors to recolonise.
When to Go Professional
For anything beyond a handful of bugs caught very early, professional treatment is almost always the right call. The two main professional options:
- Chemical treatment: A pest controller applies residual insecticide to all harbourage areas, typically requiring 2–3 visits over several weeks. Effective and widely available.
- Heat treatment: Using professional bed bug steamers, the room is heated to over 50°C for several hours, killing all life stages including eggs in a single visit. More expensive but highly effective, especially for severe infestations.
Whichever route you take, mattress encasements should be fitted as part of the treatment plan — they trap any remaining bugs inside and prevent recolonisation of the mattress.
Protect Yourself When Travelling
Travel is one of the most common ways bed bugs enter homes. Our moving house pest checklist covers pre-move inspections, and the same principles apply to hotel stays: inspect the mattress and headboard before unpacking, keep luggage on hard surfaces, and wash everything on a hot cycle when you return home.
