Identification
Cimex lectularius adults are 4 to 5mm long, flat, oval-shaped, and reddish-brown (darker red after a recent blood meal). Unfed adults are about the size and colour of an apple seed; fed adults are plumper, rounder, and darker. No wings at any life stage — bed bugs do not fly. Six legs; two antennae roughly half the length of the body. Nymphs are smaller (1 to 4mm depending on life stage) and paler, almost translucent when unfed. Eggs are tiny (1mm), white, and cemented in clusters in hidden seams. The closely related bat bug (Cimex adjunctus) occurs in BC and is essentially indistinguishable without microscopy — but when both are present, treatment is typically the same. Bed bug droppings are dark black or rust-coloured specks, often smeared as small commas on mattress fabric or sheets.
Habitat in BC
Bed bugs live close to hosts — within 2 metres of a sleeping human is standard. In Metro Vancouver homes that means mattress seams, box-spring corners, bed-frame joints, headboard backs, bedroom baseboards, behind picture frames adjacent to beds, inside nightstand drawers, and along the seams of bedroom upholstered furniture. Couch-sleeping pattern homes add living-room sofas to the list. Hotels, Airbnbs, backpacker hostels, and multi-unit rental housing are epidemic pressure sources — Vancouver hotels saw a meaningful bed-bug resurgence through 2024–2026 following the post-pandemic travel rebound. Cross-unit migration in strata buildings through shared walls, electrical conduits, and shared laundry is documented. Neighbourhood distribution is essentially universal but heavier in denser multi-family housing.
Signs you have bed bug
- Itchy bites in lines or clusters on exposed skin (arms, legs, neck, back) appearing overnight — classic 'breakfast, lunch, dinner' pattern of 3 adjacent bites.
- Small dark specks on mattress seams, box-spring corners, or sheets — bed-bug droppings, often smeared as commas.
- Visible bugs — adult Cimex lectularius in mattress seams, under headboard edges, or in bed-frame joints.
- Small blood smears on sheets from bugs crushed during sleep.
- A sweet, musty, raspberry-like odour in the bedroom (heavy infestations only).
- Recent history: hotel stay, travel, second-hand furniture purchase, or a new resident in an adjacent unit.
Risk & damage
Bed bugs are not a disease vector — decades of research have found no meaningful role for Cimex lectularius in transmitting human pathogens, despite their blood-feeding habit. The direct health risks are meaningful but indirect: severe itching, secondary skin infections from scratching, allergic reactions in sensitive individuals, and most significantly documented psychological effects — insomnia, anxiety, and in prolonged infestations depression-like symptoms. For Metro Vancouver rental housing the regulatory and financial stakes are substantial: documented bed-bug presence affects unit habitability under BC's Residential Tenancy Act, and hotels with repeat bed-bug complaints face real reputational and revenue consequences.
Seasonality in Metro Vancouver
Bed bugs show essentially no seasonal variation — they live entirely in heated human structures and are not exposed to outdoor climate. Indoor populations grow year-round. Metro Vancouver call volume does show some modest seasonality driven by travel patterns: summer travel season (July through September) and the winter holiday travel peak (mid-December through early January) both produce bed-bug introduction spikes as travellers return home with hitchhikers from hotels. Strata-building cross-unit migration is continuous year-round. The 2025–2026 travel rebound has produced meaningfully elevated 2026 call volume across Metro Vancouver compared to pre-pandemic baselines.
Treatment approach
Bed-bug thermal treatment is our flagship bed-bug protocol and is overwhelmingly the most effective approach. We raise the temperature of affected rooms above 48°C (118°F) for several sustained hours using professional-grade electric heaters with distributed temperature sensors, killing every bed bug in every life stage — including eggs — in a single session. Treatment time is 6 to 8 hours for a typical home. We combine thermal with targeted residual pyrethroid at baseboards and furniture seams as a backup insurance policy. Pre-treatment client preparation is essential — removal of heat-sensitive items, laundering of bedding at 60°C or above, clearing of wall-adjacent furniture for heat circulation. A 90-day post-treatment warranty is standard. Chemical-only treatment is offered as a lower-cost alternative but typically requires 3 to 4 visits over 4 to 6 weeks and has meaningfully higher failure rates due to resistance and egg survival.
When to call a professional
Call on first suspicion. Bed bugs are one of the few pests where speed of response dramatically affects treatment cost and duration — a two-bug introduction treated in week one is a single-room thermal visit; the same introduction treated in month six is a whole-home infestation with cross-unit migration risk. DIY bed-bug treatment with retail sprays is essentially always ineffective because retail products do not reach harbourage and do not kill eggs; multiple studies including work by the US EPA have documented resistance to pyrethroid actives in common retail sprays. For hotel or Airbnb concerns, check mattress seams before unpacking on arrival.
Prevention playbook
How to prevent bed bug in Metro Vancouver homes
- 1
Inspect hotel rooms before unpacking
On check-in, put luggage in the bathroom (bugs avoid tile). Pull back sheets and inspect mattress seams, box-spring corners, and headboard edges with a flashlight for live bugs, dark specks, or shed skins. This 60-second check is the single most effective prevention action any Metro Vancouver traveller can take.
- 2
Heat-treat travel luggage on return
After any hotel or Airbnb stay, run clothes through a clothes dryer on HIGH heat for 30 minutes (washing alone is not sufficient — the heat kills bugs and eggs). Store suitcases in a garage or sealed bag away from bedrooms until inspected.
- 3
Never bring home used upholstered furniture from the curb
Used mattresses, box springs, and sofas are the second-most-common introduction pathway after travel. Even if a piece looks clean, bed-bug eggs are 1mm and invisible under stitching. If you must buy second-hand, arrange professional inspection and a preventive thermal treatment first.
- 4
Use a zippered mattress encasement
After treatment — or as a preventive measure in multi-unit buildings — encase your mattress and box spring in a bed-bug-rated zippered encasement (look for products tested to AATCC 100 standard). This traps any bugs that penetrate and eliminates harbourage in seams.
- 5
Seal cross-unit migration paths in strata
If you live in a condo, apartment, or townhouse, ask the strata or landlord about sealing shared utility penetrations (baseboards, electrical outlets, plumbing chases) to adjacent units. Bed bugs migrate between units along these paths — sealing them cuts introduction risk substantially.
- 6
Act within 48 hours of first suspicion
Bed-bug populations double every 16 days. A 2-bug introduction treated in week one is a $600 thermal visit; the same introduction in month six is a $3,000+ whole-home treatment with unit neighbours involved. Speed matters more than thoroughness of preparation.

Frequently asked questions about bed bug
How do bed bugs get into my home?+
Hitchhiking. The documented primary pathways: hotel stays (by far the most common), travel in airline and train seating, second-hand furniture purchases (especially mattresses, box springs, couches), shared laundry facilities in multi-unit buildings, cross-unit migration through shared walls in strata, and guest visits from infested homes. One pregnant female can seed an infestation; a single travel bag can carry dozens. Vigilance after travel and with used furniture is the best prevention.
Do bed bugs spread disease?+
No, in meaningful terms. Despite decades of research — and bed bugs' blood-feeding habit — Cimex lectularius is not a documented vector for human pathogens. They don't transmit HIV, hepatitis, or any known human disease. The health consequences are localised skin reactions from bites, secondary infections from scratching, and documented psychological effects — insomnia, anxiety — from prolonged infestation. Serious, but not disease-vector serious.
Is heat treatment actually better than chemical?+
For bed bugs specifically, yes, meaningfully. Chemical treatment typically requires 3 to 4 visits over 4 to 6 weeks, struggles to kill eggs (which are sealed in a protective envelope), and faces documented pyrethroid resistance in many bed-bug populations. Heat treatment kills every life stage — eggs included — in a single 6 to 8 hour session at 48°C+. Upfront cost is higher; total cost (including re-visits and failure rates) is typically lower. The disruption is also substantially smaller: one day, one treatment, 90-day warranty.
Do I have to throw out the mattress?+
Not usually. Thermal treatment kills bed bugs inside the mattress rather than requiring disposal. For chemical-only treatment, mattress encasements (bed-bug proof zipper covers) are an effective retention strategy. The exceptions are mattresses that are physically damaged or contaminated beyond cleaning — in which case disposal is the right call, but this is a mattress-condition decision, not a pest-control requirement.
How do I know I brought them back from a hotel?+
Inspect luggage on arrival before unpacking: look at luggage seams, inspect the luggage-stand in the hotel room, and check mattress seams at the hotel itself (look for dark specks or visible bugs). On return home, unpack directly into a laundry cycle — 60°C dryer for 30 minutes kills all life stages. High-risk travel (hostels, questionable Airbnbs) warrants inspection on arrival. For a recent hotel stay with subsequent bite onset, assume Cimex lectularius until professionally excluded.
What about landlord responsibility?+
Generally a landlord responsibility under BC's Residential Tenancy Act, unless the infestation is clearly caused by tenant action (introducing infested second-hand furniture, for example). Landlords must maintain units in habitable condition and bed bugs affect habitability. Document the infestation in writing, notify the landlord formally, allow reasonable response time, and escalate to the Residential Tenancy Branch if remediation is refused. Single-unit treatment often fails in multi-unit buildings without building-wide coordination.
