Bed Bug FAQ — 20 Questions Answered by Hong Kong's Bed Bug Specialists

The three most common signs are:

• First: waking up with rows or clusters of itchy red bites on your arms, neck or legs (bed bug bites often appear in a line or triangle pattern);
• Second: small black spots — bed bug droppings — on your sheets, mattress seams or bed frame;
• Third: spotting flat, reddish-brown insects about the size of an apple seed crawling near the bed at night.

No, not at all! Bed bugs are among the most resilient household pests:

• Extremely high reproductive rate: A single female bed bug can lay hundreds of eggs in its lifetime, which hatch in about 1 to 2 weeks.
• Extremely long survival period: Even without eating, bed bugs can survive for months, even close to a year.
• Rapid spread: Hong Kong’s warm and humid climate allows them to reproduce even faster. If not thoroughly treated, the problem will only worsen, and they may even spread to neighboring units along wall cracks and electrical conduits.

[Expert Advice] The earlier you treat them, the lower the cost of complete eradication.

No. Bedbugs are not directly related to environmental hygiene; five-star hotels and luxury homes can also experience infestations.

Bedbugs are primarily spread by people and objects:

• Luggage and hotel beds
• Second-hand furniture 
• Sofas in offices or friends’ homes
• Wall cracks connecting to neighboring units

⚠️ Don’t be embarrassed or guilty if you find bedbugs. The most important thing is to get them treated by a professional team as soon as possible to stop the infestation from spreading.

You can distinguish bed bug bites by the following characteristics:

Bed bug bite characteristics:

• Arrangement: Appears in rows (commonly known as a “breakfast, lunch, dinner” pattern in a straight line or triangle)
• Common locations: Concentrated on exposed skin during sleep (such as arms, neck, calves)
• Itching intensity: Very persistent, lasting 1 to 2 weeks
• Precursor signs: Silent bites

Mosquito bite characteristics:

• Arrangement: Randomly and sporadically distributed
• Common locations: Any exposed area
• Itching intensity: Usually subsides within hours to days
• Precursor signs: Usually accompanied by buzzing sounds when flying

💡 If you frequently find new bites upon waking in the morning, it is very likely due to bed bugs. It is recommended to check the seams of your mattress as soon as possible.

According to current international research, bed bugs are not known disease vectors (unlike mosquitoes and ticks).

However, the harm caused by bed bugs is still quite serious:

• Physical effects: Bites can cause severe itching and skin allergies; excessive scratching can lead to secondary bacterial infections.
• Psychological effects: Long-term bed bug infestation can lead to severe insomnia, anxiety, and significant psychological stress.

Therefore, even if they do not transmit viruses, treatment should never be delayed.

• Resistance Development: Bed bugs in Hong Kong have developed strong resistance to common household pesticides (such as pyrethroids), a fact confirmed by international academic research.
• Insufficient Egg Killing: Insecticides only target some adult bugs and cannot kill the eggs completely. The eggs hatch in about two weeks, and the infestation will return.
• Disturbing the Bed Bugs and Spreading: Bed bugs, stimulated by chemicals, will scatter in panic, spreading from the bedroom to the living room and other rooms, making control much more difficult.

Absolutely not recommended!

• Inability to penetrate hiding places: The smoke from smoke bombs only floats on the surface, making it extremely difficult to penetrate deep into mattresses, wall crevices, and bed frame gaps—the core hiding places of bed bugs.
• 「Spreading before they die」: The smoke strongly irritates bed bugs, causing them to frantically flee before they are poisoned, spreading from a single room to the entire house. Most of the cases we receive that require assistance have resulted in a severe worsening of the infestation due to the use of smoke bombs.

While steam can kill bed bugs upon direct contact with the nozzle, it cannot eradicate the infestation throughout the house:

• Rapid cooling: The temperature of the steam drops rapidly just centimeters from the nozzle, insufficient to maintain the high temperature needed to kill bed bugs.
• Insufficient penetration: The steam cannot penetrate the inner layers of mattresses or deep crevices, rendering it ineffective against the hundreds of adult bugs and eggs hidden inside.
• 「Kill one at a time」: Traditional steam treatment only addresses the affected area. To completely eliminate bed bugs, the temperature must rise evenly throughout the entire space and be maintained for a sufficient time; this is the core principle of thermal treatment.

• Uniform Heating Throughout the House: NOBEDBUGS-HK uses its own professionally developed heating system to safely heat infested spaces to 60°C and maintain this temperature for up to 3 hours.
• Deep Penetration Without Dead Angles: The intense heat penetrates every corner of mattresses, sofas, wall crevices, and appliances, thoroughly killing adult bugs and eggs in one go.
• Exclusive Sealing Formula: Combined with an exclusive, proprietary silica gel powder formula, it blocks bed bug escape routes.

By any professional standard, high-temperature thermal treatment is the most thorough and safest solution for eliminating bedbugs:

🔥 High-Temperature Thermal Treatment (Best Choice)

• Advantages: Physically heats up the insects, penetrating deep into furniture and wall crevices; kills adult bedbugs and eggs in one treatment; bedbugs cannot develop resistance; zero chemical residue; occupancy is possible immediately after cooling down.

💊 Traditional Chemical Treatments

• Disadvantages: Currently bed bugs are becoming increasingly resistant to chemicals; chemicals cannot kill eggs and require 2-3 more applications; leaves chemical odors and toxicity.

💨 Steam Treatment

• Disadvantages: Temperature drops rapidly after leaving the nozzle, unable to penetrate deep into mattresses; only kills individual bedbug, failing to eradicate large, hidden colonies and eggs.

💣 Insect-killing fog bombs (worst choice)

• Disadvantages: The insecticidal fog cannot penetrate deep into crevices and cracks, and may instead disturb bed bugs, causing them to spread to other rooms and even neighboring units, resulting in “the bedbugs spreading before they die”.

Extremely safe!

• Zero chemical residue: The thermal treatment process utilizes purely physical high temperatures, leaving zero chemical dosage and toxic residue. After treatment and cooling, the room can be used normally immediately, with no need to worry about children, infants, or pets coming into contact with harmful agents.
• Simple and safe: During treatment, family members and pets only need to temporarily leave the unit.

💡 This is also the core reason why more and more Hong Kong families, kindergartens, and five-star hotels are choosing high-temperature thermal treatment.

Absolutely no hassle required!

• No complicated preparation: We operate on a “zero-preparation” principle. Upon arrival, our team will conduct a thorough inspection and provide guidance. You will essentially not need to fold clothes, move beds, or wash all your garments (these are requirements for old-fashioned chemical treatments).
• Simple removal of heat-sensitive items: Generally, only a few heat-sensitive items need to be removed beforehand (such as candles, chocolates, aerosol cans, and some electronic devices). We will provide a simple checklist before the treatment and assist you step-by-step throughout the process.

The heat treatment takes the whole day. Usually from 9am to 5pm (depending on the size of the unit/house to be treated)

• Immediate Move-in: Depending on the unit size and the severity of the pest infestation, most residential units can have all work completed on the same day.
• No Need to Move Out: After treatment and cooling, residents can return home immediately to resume normal routines and sleep, unlike traditional chemical treatments which require several days of temporary accommodation.
• Rapid Business Reopening: Hotel rooms can also be reopened for rent immediately, minimizing business losses.

This stands from our absolute confidence in our proprietary technology!

• Traditional methods are ineffective: Traditional chemical pesticides cannot kill the eggs, leading to a high recurrence rate in a short period. Therefore, most companies only offer a 3-month maintenance course or even none at all.
• Double protection for complete eradication: High-temperature heat treatment kills both adult insects and eggs in one go, combined with our proprietary protective powder for continuous defense.
• We dare to promise: if bed bugs unfortunately recur within the 1-year maintenance period, we will provide free on-site treatment. This commitment is rare in the pest control industry in Hong Kong and even globally.
