Bed bug infestations are rising globally, with reports surging in major cities and hotel chains since 2023. Travelers face the highest risk. Knowing how to inspect a room, recognize bites, and treat luggage can significantly reduce your chances of bringing bed bugs home.
You book the hotel. You check the reviews. You pack your bags. What you probably don’t check for—but should—is whether something tiny, flat, and bloodthirsty has already claimed your bed.
Bed bugs never truly disappeared. But after years of relatively quiet reports, they’ve surged back into public consciousness. In late 2023, Paris experienced a widely reported bed bug outbreak that spread across public transport, cinemas, and hotels. The story went viral. Suddenly, travelers everywhere were second-guessing their next trip.
The resurgence isn’t confined to Paris. Pest control companies across the United States, United Kingdom, and Australia have reported significant upticks in infestations. Hotels, hostels, Airbnbs, and even luxury accommodations are not immune. If you travel regularly—whether for work or leisure—understanding bed bugs is no longer optional.
This post breaks down why bed bugs are back, how to spot them before they spot you, and what to do if you suspect you’ve brought one home.
Why Are Bed Bug Infestations on the Rise Again?
Bed bugs (Cimex lectularius) were nearly eradicated in developed countries during the mid-20th century, largely thanks to the widespread use of DDT. After DDT was banned for its environmental toxicity, bed bug populations slowly began recovering. By the early 2000s, infestations were climbing again.
Several factors have accelerated the current resurgence:
- Pesticide resistance. Bed bugs have developed resistance to many common insecticides, including pyrethroids, which are widely used in pest control. According to a study published in the Journal of Medical Entomology, resistant populations are now found across multiple continents.
- Increased global travel. More people traveling means more opportunities for bed bugs to hitchhike from city to city. A single infested hotel room can seed dozens of homes as guests unknowingly carry bugs in their luggage.
- Reduced public awareness. Younger generations have little experience identifying or responding to infestations, which allows problems to go undetected longer.
- Shorter hotel cleaning windows. High turnover in budget and mid-range accommodations means housekeeping staff may not conduct thorough inspections between guests.
The Paris outbreak of 2023 was a stark illustration of how quickly bed bugs can spread through dense urban environments. French authorities confirmed sightings on trains, in airports, and across thousands of hotel properties.
What Do Bed Bugs Look Like—and Where Do They Hide?
Bed bugs are small—adult bugs measure roughly 5–7mm, about the size of an apple seed. They’re oval-shaped, flat when unfed, and reddish-brown in color. After feeding, they become swollen and darker.
Spotting them requires knowing where to look. Bed bugs are nocturnal and hide during daylight hours in tight, dark spaces close to their food source: you.
Common hiding spots in hotel rooms include:
- Mattress seams and piping
- Box spring joints and stapled fabric
- Headboard cracks and screw holes
- Behind wall-mounted artwork or loose wallpaper
- Inside electrical outlets and baseboards
- Along the seams of upholstered furniture
Bed bugs don’t just live in beds—despite the name. Any soft furnishing near where people sleep or rest is a potential habitat.
How to Tell Bed Bug Bites from Other Insect Bites
Bed bug bites often appear as small, red, itchy welts. They typically occur in clusters or a line, reflecting the bug’s feeding pattern as it moves across skin. Common bite sites include the arms, neck, shoulders, and legs—areas exposed during sleep.
The tricky part: reactions vary dramatically. Some people develop visible, itchy welts within hours. Others show no reaction at all, making it possible to be bitten repeatedly without realizing it. Bites alone are not a reliable indicator of infestation.
More reliable signs include:
- Small rust-colored stains on bed linen (from crushed bugs or excrement)
- Tiny dark spots on mattress seams (fecal matter)
- Shed exoskeletons near seams or in crevices
- A faint, musty odor in heavily infested rooms
How to Inspect a Hotel Room for Bed Bugs
This is a skill every traveler should develop. It takes under five minutes and can save you weeks of stress.
Step 1: Leave your luggage in the bathroom or on a hard floor. Bed bugs can’t climb smooth surfaces as easily. Keep bags off upholstered chairs and away from the bed until you’ve completed your check.
Step 2: Pull back the bedding. Strip the top covers and inspect the fitted sheet, paying close attention to the corners and edges of the mattress.
Step 3: Check the mattress seams. Run your fingers along all four sides, flipping up the piping to look underneath. Use your phone’s flashlight for better visibility.
Step 4: Inspect the headboard. If it’s mounted to the wall, try to pull it slightly forward. Check screw holes and any cracks in the frame.
Step 5: Look at the box spring. Flip the mattress if possible. The underside of the box spring—particularly where fabric is stapled—is a prime hiding spot.
If you find anything suspicious, request a different room and ask that it be on a different floor. Bed bugs can move through walls and travel between adjacent rooms.
How to Protect Yourself During and After Travel
Inspection is your first line of defense—but not your only one. These precautions reduce your risk significantly.
During your stay:
- Store luggage on metal luggage racks rather than on carpet or upholstered furniture.
- Keep clothing in sealed plastic bags inside your suitcase.
- Avoid placing clothes in hotel dressers for short stays.
When you return home:
- Unpack outside or in a garage rather than a bedroom.
- Immediately wash all clothing on the hottest cycle the fabric allows. Bed bugs die when exposed to temperatures above 120°F (49°C) for at least 20 minutes.
- Place luggage in a sealed plastic bag and consider using a portable heat treatment bag designed to kill bed bugs in baggage.
- Vacuum suitcases thoroughly and dispose of the vacuum bag immediately.
What Should You Do If You Think You’ve Brought Bed Bugs Home?
Act fast. The longer an infestation establishes itself, the harder it becomes to eliminate.
Contact a licensed pest control professional as soon as possible. Self-treatment using over-the-counter sprays is rarely effective, particularly against pesticide-resistant populations. A professional will typically conduct a full inspection, confirm the infestation, and recommend either chemical treatment or heat treatment—the latter being increasingly preferred for its effectiveness and low toxicity.
Avoid moving furniture or bedding between rooms before treatment, as this can spread bugs to unaffected areas.
What Accommodations Are Most at Risk?
No accommodation type is completely safe, but risk levels vary. Budget hostels and older hotels with high turnover face the greatest challenges due to rapid room cycles and aging infrastructure. That said, five-star hotels are not immune—bed bugs care about warmth and proximity to hosts, not star ratings.
Properties that actively invest in prevention—including staff training, mattress encasements, and routine inspections—present lower risk. When in doubt, check recent reviews on platforms like TripAdvisor or Google. Guests who encounter bed bugs rarely stay silent.
The Bottom Line: Stay Vigilant, Not Paranoid
Bed bugs are a real and growing concern for travelers, but they’re manageable with the right knowledge. A five-minute room check costs nothing. Washing your clothes immediately after a trip is a small habit with meaningful protective value.
The goal isn’t to avoid travel—it’s to travel smarter. Staying aware of where you place your belongings, knowing what to look for, and responding quickly if something seems off puts the odds firmly in your favor.
Frequently Asked Questions About Bed Bugs and Travel
Can bed bugs survive in luggage for long periods?
Yes. Bed bugs can survive for several months without feeding under the right conditions, making it possible for them to travel long distances in luggage and remain viable for weeks after your trip ends.
Do bed bug-proof mattress encasements actually work?
Mattress encasements prevent bugs from entering or escaping a mattress, but they don’t eliminate an existing infestation elsewhere in the room. They’re most effective as a preventive measure in your own home.
Can bed bugs travel through hotel walls?
Yes. Bed bugs can move through wall cavities, electrical conduits, and shared plumbing spaces. If your neighbor’s room is infested, requesting a room on a different floor—not just down the hall—reduces your risk.
How long does it take for a professional bed bug treatment to work?
Chemical treatments typically require two to three visits over several weeks to fully eliminate an infestation. Heat treatments can be completed in a single session but require professional equipment to reach lethal temperatures throughout the space.
Are luxury hotels safer from bed bugs than budget ones?
Not necessarily. Bed bugs are attracted to warmth and carbon dioxide, not price points. High-end hotels can and do experience infestations—though well-maintained properties with proactive protocols generally catch problems earlier.
Should I be worried about bed bugs on planes or public transport?
The risk is low compared to accommodations, but not zero. Upholstered seats on long-haul flights and trains can harbor bugs. Using a thin blanket or scarf as a barrier between your skin and the seat offers some protection.
