How to Check for Bed Bugs After Travel
By Henry, Taff Pest Control · Reviewed August 2026
August is peak season for two things: holidays, and the bed bug calls that follow them a few weeks later. Bed bugs don’t crawl in from the garden. They’re carried, in luggage, second-hand furniture and occasionally a visitor’s coat. Knowing how to check for bed bugs (in the hotel room and again when you get home) is the difference between a two-minute inspection and a multi-room treatment.
One thing before the practical advice: bed bugs carry a stigma they don’t deserve. They turn up in immaculate homes and good hotels constantly. Finding them says nothing about you except that you’ve travelled.
What you’re actually looking for
People expect to find the bugs themselves. Usually you find the evidence first:
Black ink dots. The most reliable sign. Bed bug droppings look like clusters of black felt-tip dots, concentrated along mattress seams and in the corners and joints of bed frames. One dot means little; clusters mean activity.
Blood spotting. Small rust-coloured smears on sheets, the aftermath of feeding. Easy to dismiss individually; meaningful alongside the dots.
Shed skins and eggs. Bed bugs moult as they grow, leaving pale, papery casts of themselves. The eggs are tiny, whitish and glued into seams and crevices, and hard to spot, which is why the droppings matter more.
The bugs. Adults are the size and shape of an apple pip: flat, red-brown, and quick to retreat from light. Flat means unfed; rounder and darker means recently fed.
Bites are the least reliable sign of all. Some people don’t react to them; others react to things that aren’t bed bugs. Carpet beetle rashes are mistaken for bed bug bites all the time. Never diagnose from bites alone. Look for the physical evidence.
The two-minute hotel room check
Do this before you unpack. It’s the habit that keeps them out of your house:
1. Keep your case off the bed and floor. The luggage rack or a hard surface, away from the bed, until you’ve checked.
2. Pull back the bedding at the head end. Lift the sheet at the corners nearest the headboard and run your eye along the mattress seams and piping. The head end is where they concentrate, because it’s closest to the sleeper.
3. Look behind the headboard if it moves easily. Hotel headboards are a favourite harbourage: dark, undisturbed and inches from the food.
4. Check the bedside furniture. Drawer joints and the underside edges of bedside tables, anywhere wooden pieces meet.
Nothing found? Unpack and enjoy the holiday. Found the dots or worse? Photograph everything, ask for a different room well away from that one (not next door, they travel through walls), and keep your luggage sealed in the meantime.
When you get home: the habits that catch stowaways
Even after a clean-looking stay, a little caution costs nothing:
Unpack on a hard floor, not on the bed and not on bedroom carpet. Kitchen or bathroom floors give a stowaway nowhere to hide and you a clear view.
Wash the washables at 60°C and tumble-dry what the labels allow on a hot cycle. Heat is what kills bed bugs and their eggs reliably; a cool wash isn’t enough.
Inspect the case itself (seams, pockets and zips) before it goes away. Store luggage somewhere that isn’t the bedroom if you can.
Then stay alert for a few weeks. A small number of stowaways takes time to make themselves known: eggs hatch in around a fortnight, and the early signs are subtle. The ink dots along your own mattress seams are what you’re watching for.
Found the signs at home? Do less, not more
The instinct is to attack the bed with a shop spray. It’s the single worst move available. Spray insecticide at a bed bug colony and you scatter it: deeper into the room, into the sofa, into the next bedroom. What began as one bed’s problem becomes a whole-flat problem, and the professional job gets bigger and longer as a direct result.
Don’t start sleeping in another room, either. They follow the sleeper, and you’ll seed the second room on the way.
What works: leave everything where it is, photograph what you’ve found, and get it looked at. Our bed bug treatment starts with an inspection that maps exactly how far they’ve spread. That mapping decides everything that follows, and it’s far easier when the evidence hasn’t been sprayed and shuffled. It’s a discreet visit as standard: unmarked vehicle, no branded uniform or signage.
Common questions
What do bed bug bites look like?
Typically small, itchy red bumps, often in lines or clusters where skin met the mattress. But reactions vary hugely: some people don’t mark at all, and carpet beetle rashes mimic them closely. Bites raise the question; the mattress-seam evidence answers it.
Can I have bed bugs without being bitten?
You can be bitten without reacting, which amounts to the same thing. Around half of people show little or nothing. That’s why one partner can be “eaten alive” while the other doubts the whole thing. Check the seams, not the skin.
Do bed bugs mean my home is dirty?
No. Bed bugs feed on people, not dirt. They go wherever people sleep, and they arrive by hitching, not through poor housekeeping. Immaculate homes get them constantly.
How soon after a trip would I know?
Sometimes within days, but a small introduction can take several weeks to become noticeable. Eggs hatch in roughly two weeks and numbers build slowly at first. Keep half an eye on the mattress seams for a month after a suspect stay.
Will washing my clothes get rid of them?
A 60°C wash and a hot tumble-dry deals with what’s in the laundry. It doesn’t touch anything that’s already reached the bed or the room; that’s where a proper inspection comes in.
Worth reading: Cardiff Council lists a flat bed bug fee by house size, but has paused home treatments for now; our council pest control comparison explains what that fee covers and what neighbouring councils offer.
