Hotel Bed Bugs: How to Check Your Room Before Sleeping
Even well-run hotels can encounter bed bugs. They hitchhike on luggage and clothing, then hide in seams and cracks until night. A calm, methodical check takes just a few minutes and dramatically reduces your risk. Below is a science-led inspection you can do safely before you settle in, plus what effective professional remediation looks like if a room is affected.
What people believe vs reality
- Belief: Bed bugs only occur in dirty hotels. Reality: They travel with guests; five-star properties get them too.
- Belief: If I can’t see them, they’re not there. Reality: They’re cryptic; juveniles and eggs are tiny and often tucked into screw holes, stitching, and headboard joints.
- Belief: A quick spray fixes it. Reality: Eggs are resilient and many populations show chemical tolerance; incomplete treatments allow survival and spread.
Science-backed facts
- Typical signs include black pinhead faecal spots, cast skins, eggs (pearl-white, glued to surfaces), and live bugs from 1–5+ mm.
- They’re attracted to sleeping hosts (CO₂ and body heat) and are most active at night.
- Lethal heat is well defined: see what temperature kills bed bugs for thresholds used by professionals.
- They spread via soft furnishings and luggage, not just beds; adjoining rooms can be affected.
Common mistakes to avoid
- Putting luggage on the bed before you check.
- Only glancing at the top sheet—bugs hide under the piping and along the headboard edge.
- Relying on bite marks alone; many rashes mimic bed bug bites.
- Using aerosols or foggers in a hotel room—these can disperse bugs and rarely affect eggs.
- Accepting a move to the room next door or directly above/below an affected room.
Practical, safe checks you can do in minutes
- Park your luggage smartly: Place bags in the bathroom or on the rack after inspecting the rack’s straps and screw joints. Avoid the bed until checks are done.
- Strip and scan the bed: Pull back bedding. Use your phone torch to examine mattress piping, labels, handles, and corners. Look for black spots, pale eggs, or live insects.
- Headboard and bed frame: Run the torch along the top and sides of the headboard, behind it if it’s liftable, and around screw holes and brackets.
- Bed base and bedside: Check the base seams, castors, and the top of the bed base where it meets the mattress. Open bedside drawers; examine runners and underside.
- Soft seating and curtains: If the room has a chair/sofa, check the seams and under the cushions; quickly inspect curtain headers and tie-backs.
If you find convincing evidence, stop unpacking, take a clear photo, and inform reception. Ask for a room that’s not adjacent, above, or below the original. On returning home, bag travel clothing and wash at 60°C or tumble-dry on high heat for at least 30 minutes; vacuum your suitcase slowly and dispose of the bag.

Why heat treatment is the superior solution for affected rooms
Cold spots are the enemy
Bed bugs exploit cool, insulated voids in furniture and wall fixings where chemical residues and casual steaming often fail to reach. Any treatment that leaves cold spots risks survival of eggs and hidden nymphs.
Sustained lethal temperature matters
Professional room heat treatments raise and hold temperatures so contents—including seams, joints, and voids—reach and maintain lethal levels for long enough. This sustained exposure is what clears all life stages in one visit.
Sensors and monitoring ensure coverage
We place multiple probes in the hardest-to-heat locations and data-log continuously to prove every cold spot is eliminated. See our bed bug heat treatment process for how we manage airflow, circulation, and verification.
All life stages, all at once
Eggs are the toughest stage; they require higher, longer heat. When applied and monitored correctly, bed bug heat treatment kills eggs, nymphs, and adults hidden deep in furnishings—without the chemical odours or lengthy re-entry delays guests dislike.
ThermoPest expertise
ThermoPest specialises in precision heat for both homes and hospitality. In hotels we combine discreet scheduling, containment plans for adjoining rooms, and commercial heat treatment for hotels and landlords to keep downtime low and verification robust. For households, our guidance on preparing your home for treatment helps ensure safe, thorough clearance the first time.
If you bring bed bugs home
Early action prevents establishment. Launder travel clothing at high heat, isolate suspect items in soluble or sealed bags, and avoid moving soft furnishings between rooms. If an inspection confirms activity, heat is typically the fastest route to full eradication with minimal rework and no lingering residues.
FAQ’S
Question: What are the quickest checks I can do before putting my luggage down?
Answer: Place bags in the bathroom or on a cleared, inspected luggage rack first. Use your phone torch to scan mattress piping, labels, headboard edges, and the top of the bed base for black spots, eggs, or live bugs. These are the highest-yield locations in a two–five minute check. Pro tip: carry a few clear zip bags—if you find a specimen, you can safely contain it for hotel staff; in professional practice we always verify with visual or physical evidence.
Question: I found a suspicious black spot—does that confirm bed bugs, and what should I do?
Answer: Not always; make-up, pen marks, and general wear can mimic faecal spotting. Bed bug faecal spots are typically pinhead-sized, dark, and bleed slightly into fabric; confirmation is stronger if you also find cast skins, eggs, or a live insect. Stop unpacking, take a clear photo, and request a room non-adjacent, above, or below the original. In professional practice we also inspect neighbouring rooms and heat-treat confirmed areas to remove uncertainty.
Question: Do bite marks prove a hotel room has bed bugs?
Answer: No—skin reactions vary widely and many rashes look similar. Without physical evidence (live bugs, eggs, cast skins, or characteristic spotting), bites alone are not definitive. Log the timing and location of any reactions and perform a focused bed check that night. In professional practice we pair guest reports with inspection findings before deciding on treatment.
Question: Can I use a hairdryer or a DIY spray to fix a problem I notice?
Answer: Household hairdryers rarely deliver sustained lethal heat to hidden voids, and DIY sprays often scatter insects while leaving eggs untouched. Bed bugs survive in cool crevices that casual methods fail to heat evenly, creating cold spots. If you encounter evidence, inform the hotel rather than attempting treatment yourself. In professional practice, we use controlled, room-scale heat with sensors to ensure all areas reach the required temperature.
Question: Why do some hotels see bed bugs return after treatments?
Answer: Two reasons: re-introduction by new guests, and incomplete prior control that left eggs or cold spots. Single-chemical or patch treatments struggle with hidden harbourages and egg resilience, so low-level survivors can rebound. Hotels need confirmed eradication plus ongoing monitoring and staff awareness to catch re-introductions early. In professional practice, documented heat treatment and follow-up inspections minimise recurrence and downtime.
