Understanding how bed bugs actually live, move, and reproduce is the key to eliminating them effectively. Many myths persist, but the science is clear: bed bugs are highly adapted to hide near sleeping humans, feed briefly, and exploit our furniture and belongings to spread. If you’re finding bites or spotting dark flecks and shed skins, you’re not alone—and with the right approach, this can be resolved.
At ThermoPest, we specialise in whole-room heat eradication, an approach designed around bed bug biology rather than guesswork. Unlike general sprays or foggers, heat reaches deep into harbourages and destroys all life stages, including eggs, in a single, carefully controlled treatment. When you’re ready, our bed bug heat treatment and our bed bug heat treatment process explain exactly how we achieve consistent, verified results.
What people believe vs reality
- Belief: “I don’t see bugs, so it can’t be bed bugs.” Reality: Most activity happens at night, and adults often hide in seams, screw holes, and inside frames; eggs are pinhead-sized and pearly white.
- Belief: “A quick spray will sort it.” Reality: Modern bed bug populations frequently show reduced sensitivity to common insecticides, and eggs are naturally more resilient.
- Belief: “If I move rooms, they’ll stop.” Reality: Moving spreads the infestation to new sleeping areas; they follow where we sleep because that’s where CO₂ and warmth signal a blood meal.
- Belief: “They only live in beds.” Reality: They prefer bed frames and mattresses but also hide in bedside furniture, skirting, headboards, picture frames, and soft furnishings.
Science-backed facts about bed bug biology
Cimex lectularius (the common bed bug) progresses through five nymphal stages to adulthood, requiring a blood meal to moult at each stage. In typical indoor conditions, they can complete a generation in weeks, but cooler rooms slow development. They use aggregation pheromones and crevice-rich harbourages to cluster near us, reducing exposure and making spot treatments unreliable. Heat tolerance is their Achilles’ heel: when core temperatures of insects and eggs reach lethal thresholds and are held there long enough, mortality is complete. See our guide on what temperature kills bed bugs for the detailed science of time and temperature.
Common mistakes that keep bed bugs lingering
- Using total-release foggers: They rarely penetrate deep harbourages and can drive bugs deeper into structures.
- Over-reliance on sprays: Surface residues don’t reach inside joints and eggs can survive; repeated use can lead to avoidance behaviour.
- Moving or discarding beds prematurely: You risk spreading the problem via stairwells, lifts, and vehicles.
- Stopping too soon: Bites often diminish before every last egg has hatched; without proper verification, a few survivors can repopulate.
Practical, safe steps you can do now
- Reduce clutter around the bed to expose harbourages and make inspection easier.
- Hot-launder bedding and nightwear at 60°C where the fabric care label allows, then dry on the hottest safe setting.
- Vacuum slowly along mattress seams, bed joints, and skirting using a crevice tool; dispose of the bag immediately.
- Use mattress and base encasements after treatment to block hidden refuges and catch any late hatchlings.
- Plan for professional verification—sticky monitors and interceptors help you monitor your property after treatment.

Why heat treatment is the superior solution
Eliminates cold spots with engineered airflow
Professional heaters and high-flow fans are positioned to remove “cold spots” behind furniture and within voids. This matters because even small cool refuges can shelter eggs or nymphs. We use thermal mapping to validate that no areas lag under target.
Sustained lethal temperatures
It’s not just peak heat; it’s time at temperature. Rooms are brought to high ambient temperatures so the most insulated items reach lethal core temperatures, then held there long enough to ensure complete mortality across all life stages.
Sensors and continuous monitoring
Multiple wired and wireless probes are placed in the hardest-to-heat points—mattress seams, divan cavities, sofa frames, skirting voids—and readings are tracked throughout. This data-led approach is the reason our bed bug heat treatment process is dependable rather than hopeful.
All life stages, including eggs
Eggs are the most resistant stage and often outlive casual treatments. Whole-room heat removes this weak link by ensuring eggs, nymphs, and adults are all exposed to verified lethal conditions in one operation, reducing the need for repeated chemical applications.
If you’re comparing methods, see why heat treatment works better than chemicals in environments where bugs hide deep and eggs are protected.
ThermoPest expertise call-out
ThermoPest focuses on bed bug heat eradication for homes, flats, and shared lodging, as well as complex, multi-room settings. For businesses, our commercial heat treatment for hotels and landlords is designed to minimise downtime and protect brand reputation with discreet scheduling and documented verification. Whether domestic or commercial, we combine expert inspection, data-logged heating, and follow-up checks so you can be confident the problem is fully resolved.
FAQ’S
Question: What temperature and exposure time actually kill bed bugs and their eggs?
Answer: Lethality is a combination of temperature and time: insects and eggs must reach a lethal core temperature and stay there long enough. Adults and nymphs succumb more quickly than eggs, which are the most heat-tolerant stage. Professional treatments elevate room air well above lethal thresholds and hold it so that the coldest, most insulated items also reach kill temperature. A quick surface blast isn’t enough; in professional practice we confirm with multiple temperature probes placed in hard-to-heat spots.
Question: Why do DIY heaters and steamers often fail to clear an infestation?
Answer: Household devices struggle to deliver even, sustained heat into deep harbourages and may leave cold spots in joints, frames, and soft furnishings. Steam can help reduce visible bugs on contact, but eggs tucked inside furniture frames are insulated and frequently survive. Missed pockets allow a small population to rebound within weeks. As a safer step, use steam only on accessible seams and pair it with monitoring; in professional practice we heat entire rooms and validate temperatures with sensors.
Question: Could bites continue after treatment, and does that mean it failed?
Answer: Bite-like reactions can persist for days due to delayed skin responses, and some people react to dust or other insects, too. True ongoing activity requires evidence such as fresh faecal spots, live nymphs, or new shed skins in the weeks after treatment. Monitoring traps and a scheduled follow-up inspection help distinguish reintroduction (bugs brought in again) from a surviving infestation. In professional practice we set monitors, review activity data, and confirm success before signing off.
Question: Do bed bugs hide in electronics and how are these treated safely?
Answer: Yes, small electronics offer warm, sheltered voids, and bed bugs can occasionally use them as harbourage. They’re challenging because excessive heat can damage components if not controlled. During professional heat treatment, temperatures are raised gradually and monitored so that electronics warm safely without hotspots, and sensitive items may be isolated with dedicated probes. In professional practice, careful ramp rates and targeted sensor placement protect devices while ensuring lethality to insects.
Question: How can I tell if the infestation is truly gone?
Answer: Look for an absence of fresh signs over several weeks: no new faecal spots, live bugs, or recent cast skins near sleeping areas. Use interceptors and sticky monitors to capture any stragglers and keep the bed pulled slightly from the wall to reduce bridging. Launder bedding regularly and inspect high-risk seams and joints to verify no new activity. In professional practice, we combine client feedback, trap data, and a structured re-inspection to confirm eradication.
