Bed bugs are masters at hiding — and by the time most Toronto residents are certain they have them, the infestation is already well established. Here are the five signs to look for right now:
Bed bug reports in Toronto have risen significantly since 2020, with multi-unit buildings particularly affected. High-traffic environments, such as condo laundry rooms, Airbnb rentals, and even TTC seating, are common transmission points. Toronto Public Health confirms bed bugs are consistently among the city’s most reported pest complaints.
Store-bought sprays can suppress surface activity temporarily, but they do not reach eggs hidden deep inside mattresses, wall voids, or furniture joints. If you’ve spotted signs in more than one area of your home, or if bites have continued for more than two weeks, a professional treatment is the only reliable path to complete elimination.
Every job begins with a detailed, room-by-room inspection carried out by one of our licensed technicians. We check all primary harborage zones: mattress seams and box springs, bed frames and headboards, nightstands and dressers, sofa joints, baseboards, electrical outlets, and any luggage or clothing items flagged by the resident. By the end of the inspection, you’ll know exactly where the infestation is, how far it has spread, and what treatment approach is recommended — with a transparent cost estimate before any work begins.
Thermal bed bug treatment is the most effective elimination method available. Our industrial-grade heating equipment raises the temperature of the treated space to 50°C and above — a temperature that is lethal to bed bugs at every life stage, including eggs, nymphs, and adults.
Unlike sprays, heat penetrates deep into mattresses, inside wall voids, behind baseboards, and through furniture — reaching every hiding spot in the room. The treatment is maintained at lethal temperature for 6 to 8 hours, with our technicians monitoring heat distribution throughout to eliminate any cold spots. There is no chemical resistance to heat — bed bugs cannot survive it. In the majority of cases, a single heat treatment session achieves complete elimination.
Where required — particularly in severe or multi-room infestations — we apply a targeted residual chemical treatment as a secondary barrier. This is applied to crack and crevice areas, along baseboards, and behind fixtures using Ministry of Environment-approved products.
Residents are advised to stay out of treated areas for 4 hours following chemical application. A follow-up inspection is scheduled within the guarantee period to confirm elimination and provide residual protection against any re-activity.

No — residents, children, and pets must vacate the property for the full duration of the heat treatment, typically 6 to 8 hours. We’ll give you a confirmed re-entry time before we begin.
Our technician conducts a post-treatment inspection before you re-enter. We check for any remaining live activity and document findings. If any activity is detected within your 6-month guarantee window, we return at no cost.
Yes — this is one of the most common scenarios we see in Toronto. Bed bugs can travel through shared walls, electrical conduits, and hallway carpeting. If your neighbour has had bed bugs, a professional inspection of your unit is strongly recommended even if you have no symptoms yet.
Heat treatment uses high temperatures to kill bed bugs at all life stages — including eggs — in a single session with no chemical residue. Chemical treatment uses insecticide sprays and baits and typically requires 2 to 3 visits. Heat treatment is our primary recommendation for most Toronto infestations due to its superior effectiveness and speed.
