Bedbugs are blood-sucking insects that belong to the family Cimicidae. They have been human parasites for thousands of years and have a long and complex history that spans different cultures and regions. The evolution of bedbugs can be traced back to more than 100 million years ago when they were likely feeding on the blood of bats or birds. As bats and birds began cohabitating with humans, bedbugs adapted to feed on human blood.
Bedbugs have been mentioned in ancient Greek and Roman texts and medieval European literature, where they were often associated with poverty and squalor. During the 19th and early 20th centuries, bedbugs were widespread in Europe and the United States, and their presence was seen as a significant public health problem. However, with the introduction of potent insecticides, such as DDT, in the mid-20th century, bedbugs were almost eradicated in developed countries.
However, bedbugs have dramatically returned in the past two decades, with infestations reported in hotels, homes, and public transportation systems worldwide. The resurgence of bedbugs is due to a combination of factors, including increased travel, lack of public awareness, and the development of insecticide resistance.
Bedbugs are a persistent and difficult-to-control pest, and their resurgence has become a significant public health concern. They can cause various problems, including skin irritation, allergic reactions, and psychological distress. Therefore, understanding the history and evolution of bedbugs is essential in developing effective strategies for their control and prevention.
Bed Bug infestation levels
Bed bug infestations are classified into different levels depending on the extent of the infestation and the degree of difficulty in controlling it. The different levels of bed bug infestation are as follows:
- Level 1: Minimal infestation In this level, only a few bed bugs are present in the area, and they are usually confined to a small section of the room. The bed bugs are still in the early stages of their life cycle and have not yet established a large breeding population.
- Level 2: Low-level infestation In this level, more bed bugs are present, and they have begun to spread beyond their initial area. The bed bugs may hide in cracks and crevices in the furniture, walls, or floors and may be challenging to detect.
- Level 3: Moderate infestation In this level, the bed bugs have established a breeding population, and multiple areas of the room or building are infested. The bed bugs may be visible during the day and in bedding, clothing, and furniture.
- Level 4: Severe infestation In this level, bed bugs have spread throughout the building, and many bed bugs are present. The bed bugs are visible during the day and may be seen in all building areas, including walls, ceilings, and floors. This level of infestation requires professional treatment and may require multiple treatments to eradicate the bed bugs.
It is essential to address bed bug infestations early to prevent them from becoming severe and more difficult to control. Regular inspections and early detection can help prevent the spread of bed bugs and minimize the need for extensive treatment.
Different stages of the Bed bug life cycle
Like all insects, they undergo a series of distinct life stages as they develop from an egg to an adult. Therefore, understanding the life cycle of bed bugs is essential for effectively controlling and preventing infestations.
Egg Stage The bed bug life cycle begins with an egg, typically laid in a crack or crevice near a host animal's sleeping area. Female bed bugs can lay up to 500 eggs over a lifetime, with an average of about five eggs per day. The eggs are small, white, and approximately 1mm long, making them difficult to see without magnification.
Nymph Stage Once the eggs hatch, the bed bugs enter the nymph stage. Nymphs are tiny and translucent, resembling adult bed bugs in shape and behaviour. They must feed on blood to grow and moult into the next phase stage of development. There are five nymphal instars, or stages, and each Stage takes about a week to ten days to complete.
Adult Stage After the final moult, the bed bug enters adulthood. Adult bed bugs are approximately 4-5mm in length and reddish-brown. They are wingless and have a flat, oval-shaped bodies. Adult bed bugs can survive for several months without feeding, but they typically require a blood meal every one to two weeks to reproduce and maintain their population.
Bed Bug Life Cycle Timeline The bed bug life cycle length can vary depending on environmental conditions such as temperature and humidity. Under optimal conditions, the life cycle from egg to adult can be completed in as little as four weeks. However, the life cycle can take up to four months or longer in less favourable conditions.
The following is a general timeline for the bed bug life cycle:
- Egg: 1-2 weeks
- First Instar Nymph: 1-2 weeks
- Second Instar Nymph: 1-2 weeks
- Third Instar Nymph: 2-3 weeks
- Fourth Instar Nymph: 2-3 weeks
- Fifth Instar Nymph: 2-4 weeks
- Adult: 2-4 months
Conclusion In conclusion, bed bugs goes through a series of distinct life stages as they develop from an egg to an adult. Understanding the bed bug life cycle is essential for effectively controlling and preventing infestations. Regular inspections and early detection can help prevent the spread of bed bugs and minimize the need for extensive treatment. It is essential to address bed bug infestations early to prevent them from becoming severe and more difficult to control.
Where do bed bugs hide, and why is it hard to see with the naked eye?
Bed bugs are minor and flat, making them adept at hiding in cracks and crevices. Here are some familiar places where bed bugs like to hide:
- Mattresses and box springs: Bed bugs often hide in seams, folds, and tufts.
- Furniture: Bed bugs can hide in couches, chairs, and other upholstered furniture, as well as in wooden furniture joints and crevices.
- Electrical outlets and appliances: Bed bugs can squeeze into the tiny spaces behind electrical outlets, as well as in devices such as alarm clocks, televisions, and radios.
- Curtains and drapes: Bed bugs can hide in the folds of curtains and drapes.
- Luggage and backpacks: Bed bugs can hitchhike in bags and backpacks, making them a common source of infestations in homes and hotels.
- Clothing: Bed bugs can hide in the seams and folds of clothing, shoes, and hats.
- Bedding and linens: Bed bugs can hide in sheets, blankets, and other bedding.
Seeing bed bugs with the naked eye can be challenging because they are small and often hide in hard-to-reach places. Additionally, bed bugs are nocturnal and tend to hide during the day, making it more difficult to spot them. Furthermore, bed bugs are masters of hiding and can fit into tiny spaces, making them challenging to detect. Finally, even if you see bed bugs, they can be easily mistaken for other insects or small debris, making it essential for a professional pest control company to confirm their identity.
Different bed bug treatments to get rid of Bed bugs
There are several ways to get rid of bed bugs, including:
- Professional extermination: Getting rid of bed bugs can be challenging, and it is often best to seek professional help to ensure complete eradication. Here are some professional extermination methods for getting rid of bed bugs:
- Heat Treatment: This method uses specialized equipment to heat the infested area to around 120-135°F (49-57°C), killing all bed bugs and their eggs. This highly effective treatment can be completed in a single day without chemicals.
- Chemical Treatment: Chemical treatments involve using insecticides applied to the infested area. Professional exterminators can access more robust and effective insecticides than the general public. The chemicals used are usually safe for humans and pets, but it's essential to follow the instructions provided by the exterminator.
- Steam Treatment: Steam treatment involves using specialized equipment to produce steam, which is then directed into the infested area. The heat from the steam kills the bed bugs and their eggs. This treatment is effective but may not reach all the bed bug-hiding spots.
- Vacuuming: Vacuuming is an essential part of the bed bug extermination process. Professional exterminators use specialized vacuums designed to capture bed bugs and their eggs. Vacuuming helps remove as many bed bugs and eggs as possible before applying any other treatment.
- Heat treatment: Heat treatment is considered one of the most effective methods for getting rid of bed bugs. Bed bugs are sensitive to high temperatures and cannot survive in extreme heat. During heat treatment, professional exterminators use specialized equipment to raise the temperature of the infested area to between 120 and 140 degrees Fahrenheit. This high temperature is maintained for several hours to ensure that all bed bugs and their eggs are killed.One of the advantages of heat treatment is that it can penetrate deep into cracks and crevices where bed bugs hide, making it more effective than traditional insecticide treatments. Heat treatment is also environmentally friendly, as it does not use chemicals or pesticides.However, the effectiveness of heat treatment can depend on several factors, such as the size of the infestation, the temperature and duration of the treatment, and whether all areas of the infested space can be heated adequately. Therefore, consulting a professional exterminator with experience in heat treatment is essential to ensure that the treatment is effective and all bed bugs are eliminated.
- Cold treatment: Similarly, bed bugs cannot survive below 32°F. Freezing infested items or using liquid nitrogen can also be an effective way to kill bed bugs. Cold treatment, also known as freezing, is another method for getting rid of bed bugs. Like heat treatment, cruel treatment exploits the bed bugs' sensitivity to extreme temperatures. Professional exterminators use specialized equipment to lower the temperature of the infested area to below 0 degrees Fahrenheit. This extreme cold temperature is maintained for several hours to kill all bed bugs and their eggs.While cold treatment can be effective, it is generally considered less reliable than heat treatment. This is because bed bugs have some ability to survive in cold temperatures, and it cannot be easy to ensure that all areas of the infested space reach the necessary temperature for the required duration. Cruel treatment may also be less effective at penetrating deep into cracks and crevices than heat treatment.Heat treatment is typically considered a more reliable and effective method for getting rid of bed bugs than cold treatment. However, in some situations, a combination of heat and cold therapies may be used to increase the effectiveness of the treatment. It's essential to consult with a professional exterminator to determine the best treatment options for your specific situation.
- Vacuuming: Vacuuming can physically remove bed bugs and their eggs from the affected area. Make sure to dispose of the vacuum bag or contents in a sealed container. Vacuuming can be a practical component of a larger bed bug control strategy, but it is not typically considered a standalone method for getting rid of bed bugs. However, vacuuming can help to remove bed bugs, eggs, and debris from infested areas. In addition, it can be beneficial for eliminating bed bugs from cracks and crevices, which can be challenging to reach with other methods. However, vacuuming alone is generally insufficient to eliminate a bed bug infestation, as it is unlikely to remove all bed bugs and their eggs. Vacuuming may also cause bed bugs to scatter, making the infestation more difficult to control. Professional exterminators may use vacuuming as part of an integrated pest management (IPM) strategy to eliminate bed bugs. This may include combining vacuuming with other methods, such as heat or insecticide treatments, to destroy all bed bugs. When dealing with a bed bug infestation, vacuuming can effectively eliminate them, but it is essential to do it correctly. Handheld vacuums, vacuums with cloth bags, and those with fabric hoses are not recommended because they can become infested themselves. Instead, it is best to use a vacuum with a HEPA filter for households with allergies or asthma to avoid putting insect and dust allergens back into the air. Since bed bugs and their eggs cling to wood and fabric surfaces, it's essential to use a stiff brush attachment and a back-and-forth scraping motion when vacuuming the mattress, box spring, bed frame, baseboards, non-washable furniture cushions, rugs, carpeting, heating units, baseboards, and the inside and underneath all drawers and furniture. A nozzle attachment should be used for seams and crevices. After vacuuming, let it run for a while to ensure that all bed bugs have been sucked into the bag, and then dispose of the vacuum bag in a sealed white plastic bag (this makes it easier to spot a bed bug) in a garbage bin with a lid. To prevent any bed bugs from escaping, stuff a paper towel at the end of the vacuum hose and seal it with tape. All vacuum attachments should be washed in hot water and detergent. For bagless vacuum cleaners, follow the instructions above, empty the canister contents into a plastic garbage bag, seal and dispose of the bag immediately, and wash the dust container in hot water with detergent. Finally, store the vacuum in a large plastic bag and seal it.
- Mattress and box spring encasements: These specially designed covers can trap bed bugs and prevent them from accessing or hiding in the mattress and box spring.
- Steam cleaning: High-temperature steam can kill bed bugs and their eggs on contact. This method is particularly effective for upholstered furniture and other hard-to-treat areas.
- Chemical treatments: Insecticides and other chemical treatments can effectively kill bed bugs, but they should only be used by professionals and by label instructions.
It is important to note that bed bugs are notoriously difficult to eliminate, and a combination of multiple treatment methods may be necessary to eradicate an infestation. Proper prevention measures such as regular cleaning and inspection can also help prevent future infestations.
Steaming, washing and throwing out items
- Mattresses, upholstery, and plush items infested with bedbugs but still intact should be cleaned with steam. Bedbugs will die at 50°C, and steam cleaners typically emit mist at 120 degrees (°C) or higher. Dry steam cleaners or low vapour steamers are preferable, as they leave behind less moisture. Move the steam cleaner slowly and evenly to ensure the steam kills all the bedbugs. Be sure not to use too much water, which could cause mould to form.
- Freezing small items or placing them outside can be an effective method for getting rid of bed bugs, but it is important to note that freezing temperatures must be kept for a prolonged period (4 days of consistent cold at -19°C), which may not kill all bed bugs.
- Placing small, non-washable, dry-clean-only items in a hot dryer for 30 minutes or more is recommended to eliminate bed bugs.
- Additionally, washing all mattress pads, bedding, bed skirts, infested clothes, curtains, and any other washable items in hot water is essential and dry them on the hottest dryer setting. Once things are clean and dry, store them in light-coloured, sealed, heavy-duty plastic bags or plastic storage bins with secure lids to avoid re-infesting other areas.It is essential to dispose of any items that cannot be washed, heated, or steam cleaned to prevent the further spread of the bed bug infestation.
DIY ways and home remedies and bed bug treatments to get rid of bed bugs
- Vacuuming: Regular vacuuming of the bed, mattress, and surrounding areas can help physically remove bed bugs and their eggs. It is essential to use a vacuum with a HEPA filter and dispose of the vacuum bag outside the home immediately after use.
- Steam Cleaning: Bed bugs are susceptible to high temperatures, so steam cleaning is an effective way to kill them. A steam cleaner can clean mattresses, box springs, and other infested areas.
- Diatomaceous Earth: This powder is made from fossilized diatoms and can be spread around infested areas. The powder dehydrates and kills bed bugs by absorbing the oils and fats from their exoskeletons. It is essential to use food-grade diatomaceous earth, which is safe for humans and pets.
- Tea Tree Oil: This essential oil has insecticidal properties and can repel and kill bed bugs. Mix a few drops of tea tree oil with water in a spray bottle and apply to infested areas.
- Lavender: Lavender has a calming scent that repels bed bugs. Place lavender sachets or essential oil on and around the bed to deter bed bugs from infesting the area.
- Baking Soda: Baking soda can absorb moisture and kill bed bugs. Sprinkle baking soda on the mattress and let it sit for a few hours before vacuuming it.
- Rubbing Alcohol: Rubbing alcohol can kill bed bugs on contact. Spray rubbing alcohol on infested areas and wipe them down with a cloth.
- Double-Sided Tape: Place double-sided tape around the legs of the bed and furniture to prevent bed bugs from climbing up.
- Freezing: Bed bugs are sensitive to extreme temperatures, so placing infested items in the freezer for a few days can kill them.
While these DIY methods and home remedies can effectively eliminate bed bugs, they may not be enough to stop a severe infestation. Therefore, it is essential to seek professional help if the problem persists. Additionally, it is important to practice preventative measures such as regular cleaning and decluttering to reduce the likelihood of a bed bug infestation.
FAQs
Does washing clothes in Washing Machine kill bed bugs?
Washing clothes in a washing machine with hot water (at least 60°C or 140°F) and then drying them on a high heat setting can effectively kill bed bugs and their eggs. The hot water and high heat from the dryer will dehydrate and kill the bed bugs. It is important to note that washing clothes in cold water or using a low heat setting in the dryer may not be effective in killing bed bugs. Additionally, it is recommended to seal infested clothing in plastic bags until they can be washed and dried to prevent bed bugs from spreading to other home areas.
Does talcum powder kill bed bugs?
Talcum powder is not a reliable method for killing bed bugs. While talcum powder can absorb moisture and oil from the outer layer of bed bugs, it does not kill them. The powder may temporarily cause bed bugs to become less mobile, but they will eventually recover and continue to live. Additionally, talcum powder may harm humans when inhaled in large amounts. Therefore, it is not recommended to use talcum powder as a bed bug control method. Instead, using proven techniques such as heat treatment, cold treatment, vacuuming, and insecticide sprays is best.
Are bed bug traps effective?
Bed bug traps can effectively reduce the number of bed bugs in an infested area, but they are typically not a complete solution to a bed bug problem. Traps work by luring bed bugs into a container or sticky surface where they cannot escape, which can help reduce the overall population of bed bugs. However, traps are ineffective in killing bed bugs or eliminating an entire infestation. Bed bug traps can be helpful with other control methods such as heat treatment, cold treatment, and insecticide sprays. It is important to note that not all bed bug traps are equally effective, and some may work better than others. It is best to research and choose a web that is known to be effective based on independent testing and reviews.
What about bug bombs?
Bug bombs, also known as foggers, are insecticide products that release a fog or mist of chemicals into the air to kill insects in an enclosed space such as a room or a building. Bug bombs typically come in pressurized cans or canisters and are designed to be set off in a room or area infested with insects. The fog released from bug bombs is intended to penetrate cracks and crevices where insects may hide and kill them on contact. Bug bombs are available in different formulations and may be designed to target specific types of insects, such as bed bugs or fleas. However, bug bombs can also pose risks to human health if not used properly and may not effectively eliminate all insects in an infested area. Therefore, it is essential to follow the instructions on the label carefully and take appropriate safety precautions when using bug bombs.
When to reach out to professional pest control companies to manage bed bugs?
It is advisable to contact pest control professionals to manage bed bugs as soon as you suspect an infestation. Bed bugs are notoriously difficult to eliminate, and their numbers can quickly multiply if left unchecked. If you have noticed signs of bed bugs, such as bites on your skin or bloodstains on your sheets, there is likely much more hiding in your home. Professional pest control companies have access to specialized equipment and chemicals that are more effective at eliminating bed bugs than DIY methods. They can also guide how to prepare your home for treatment and help you prevent future infestations. Additionally, suppose you have attempted to treat bed bugs without success. In that case, contacting a professional pest control company as soon as possible is a good idea to avoid further spreading the infestation.

How to destroy bed bug eggs?
Bed bug eggs are notoriously difficult to destroy as they are very small and often hidden in cracks and crevices. The methods mentioned above should kill bedbugs and their eggs too. It is important to note that destroying bed bug eggs is just one part of eliminating a bed bug infestation. It is crucial also to target adult bed bugs and any nymphs to eradicate the infestation.
Bed bugs and hotel rooms
Bed bugs are a common problem in hotel rooms. When travelling, it is essential to take precautions to avoid bringing bed bugs home with you. Here are some tips for dealing with bed bugs in hotel rooms:
- Check for Bed Bugs: Before settling into your hotel room, check the bed and surrounding areas for signs of bed bugs. Look for small brown or reddish insects, tiny white eggs, or black fecal spots. Check the mattress, box spring, headboard, and nearby furniture. Use a flashlight to help you see into cracks and crevices.
- Store Luggage Away from Bed: Keep your luggage off the bed and store it on a luggage rack or in the bathroom. Bed bugs are less likely to be found in these areas.
- Wash Clothes: When you return home, wash all your clothes in hot water and dry them on high heat. This will kill any bed bugs or eggs that may have hitched a ride home with you.
- Use Luggage Encasements: Consider using luggage encasements to protect your luggage from bed bugs. These encasements are durable, tear-resistant materials that prevent bed bugs from entering or escaping.
- Notify Hotel Staff: If you find bed bugs in your hotel room, notify the hotel staff immediately. If necessary, ask to be moved to a different room or request a refund.
Remember, bed bugs are not a sign of poor hygiene and can happen in even the cleanest hotel rooms. However, taking these precautions can help you avoid bringing bed bugs home with you and prevent an infestation in your own home.
Bed bugs and dryer sheets
There is a common belief that dryer sheets can repel bed bugs, but this is not entirely true. While dryer sheets may help mask the odour of a person, they do not repel bed bugs or prevent them from biting.
Bed bugs are attracted to heat and carbon dioxide, so they are commonly found in bedding and mattresses. Unfortunately, dryer sheets do not emit enough heat or carbon dioxide to prevent bed bugs from infesting an area.
Additionally, using dryer sheets to try and repel bed bugs is not recommended or effective for bed bug control. Instead, following proper bed bug prevention and control techniques, such as regular vacuuming, washing bedding and clothing in hot water, and seeking professional pest control services if necessary, is essential.
While dryer sheets may provide a temporary pleasant scent, they are not a reliable solution for bed bugs. Using effective and proven methods for bed bug prevention and control is essential to keep your home and bedding free of these pesky insects.
