How Do Bed Bugs Happen

Bed Bugs FAQs

What are bed bugs?

Bed bugs (Cimex lectularius) are small, flat, parasitic insects that feed solely on the blood of people and animals while they sleep. Bed bugs are reddish-brown in color, wingless, range from 1mm to 7mm (roughly the size of Lincoln’s head on a penny), and can live several months without a blood meal.

Where are bed bugs found?

Bed bugs are found across the globe from North and South America, to Africa, Asia and Europe. Although the presence of bed bugs has traditionally been seen as a problem in developing countries, it has recently been spreading rapidly in parts of the United States, Canada, the United Kingdom, and other parts of Europe. Bed bugs have been found in five-star hotels and resorts and their presence is not determined by the cleanliness of the living conditions where they are found.

Bed bug infestations usually occur around or near the areas where people sleep. These areas include apartments, shelters, rooming houses, hotels, cruise ships, buses, trains, and dorm rooms. They hide during the day in places such as seams of mattresses, box springs, bed frames, headboards, dresser tables, inside cracks or crevices, behind wallpaper, or any other clutter or objects around a bed. Bed bugs have been shown to be able to travel over 100 feet in a night but tend to live within 8 feet of where people sleep.

Do bed bugs spread disease?

Bed bugs are not known to spread disease. Bed bugs can be an annoyance because their presence may cause itching and loss of sleep. Sometimes the itching can lead to excessive scratching that can sometimes increase the chance of a secondary skin infection.

What health risks do bed bugs pose?

A bed bug bite affects each person differently. Bite responses can range from an absence of any physical signs of the bite, to a small bite mark, to a serious allergic reaction. Bed bugs are not considered to be dangerous; however, an allergic reaction to several bites may need medical attention.

What are the signs and symptoms of a bed bug infestation?

One of the easiest ways to identify a bed bug infestation is by the tell-tale bite marks on the face, neck, arms, hands, or any other body parts while sleeping. However, these bite marks may take as long as 14 days to develop in some people so it is important to look for other clues when determining if bed bugs have infested an area. These signs include:

  • the bed bugs’ exoskeletons after molting,
  • bed bugs in the fold of mattresses and sheets,
  • rusty–colored blood spots due to their blood-filled fecal material that they excrete on the mattress or nearby furniture, and
  • a sweet musty odor.

How do I know if I’ve been bitten by a bed bug?

It is hard to tell if you’ve been bitten by a bed bug unless you find bed bugs or signs of infestation. When bed bugs bite, they inject an anesthetic and an anticoagulant that prevents a person from realizing they are being bitten. Most people do not realize they have been bitten until bite marks appear anywhere from one to several days after the initial bite. The bite marks are similar to that of a mosquito or a flea — a slightly swollen and red area that may itch and be irritating. The bite marks may be random or appear in a straight line. Other symptoms of bed bug bites include insomnia, anxiety, and skin problems that arise from profuse scratching of the bites.

Because bed bug bites affect everyone differently, some people may have no reaction and will not develop bite marks or any other visible signs of being bitten. Other people may be allergic to the bed bugs and can react adversely to the bites. These allergic symptoms can include enlarged bite marks, painful swellings at the bite site, and, on rare occasions, anaphylaxis.

How did I get bed bugs?

Bed bugs are experts at hiding. Their slim flat bodies allow them to fit into the smallest of spaces and stay there for long periods of time, even without a blood meal. Bed bugs are usually transported from place to place as people travel. The bed bugs travel in the seams and folds of luggage, overnight bags, folded clothes, bedding, furniture, and anywhere else where they can hide. Most people do not realize they are transporting stow-away bed bugs as they travel from location to location, infecting areas as they travel.

Who is at risk for getting bed bugs?

Everyone is at risk for getting bed bugs when visiting an infected area. However, anyone who travels frequently and shares living and sleeping quarters where other people have previously slept has a higher risk of being bitten and or spreading a bed bug infestation.

How are bed bugs treated and prevented?

Bed bug bites usually do not pose a serious medical threat. The best way to treat a bite is to avoid scratching the area and apply antiseptic creams or lotions and take an antihistamine. Bed bug infestations are commonly treated by insecticide spraying. If you suspect that you have an infestation, contact your landlord or professional pest control company that is experienced with treating bed bugs. The best way to prevent bed bugs is regular inspection for the signs of an infestation.

Bed Bug Infestation

Bed bugs are flat and small in size, allowing them to hide easily from view during the day when they are not active. They hide in mattresses, bed frames, bedding, furniture, carpets, baseboards and bedroom clutter. They are most commonly found in the seams of mattresses or inside box springs. However, it is not necessary to locate a specimen to identify an infestation. Their excrement leaves brown to black stains on mattresses and linens, and bloodstains may be visible where bed bugs have been accidentally crushed.

Bed bugs are commonly transported within luggage, allowing them to spread anywhere humans settle. Infestations have become a problem in domestic households, hotels, dormitories and other places of residence. Because of their small size and propensity to hide within mattresses and furniture, controlling a bed bug infestation can prove difficult.

The presence of only one fertile female bed bug in a friendly environment such as a single or multiple family dwelling is an infestation that is waiting to happen. Since a healthy, blood-fed female bed bug can produce from 200-500 healthy eggs during her lifetime and may lay from 2-5 eggs each day, the likelihood of an infestation of bed bugs is extremely high unless bed bug control efforts by your pest management professional are employed to eliminate the infestation.

WHERE DO BED BUGS COME FROM?

As the name indicates, bed bugs are often found in close proximity to beds. They are attracted to and feed on warm-blooded animals to survive. This can be humans or animals, but little is known about what causes bed bugs to have a preference for humans.

BED BUGS IN THE BEDROOM

To feed on humans, bed bugs want close proximity to the host. Box springs, headboards and bed framing are favorite harborage sites for these pests. They may also settle into furniture and fixtures that are close to a bed.

Bedrooms are not the only place where bed bugs can be a concern though.

BED BUGS OUTSIDE THE BEDROOM

Bed bugs are looking for human hosts who are inactive long enough to provide a meal. The feeding doesn’t have to be at night. They will feed opportunistically, even in the daytime.

Where else might bed bugs find and feed on you?

Sitting for two hours in a movie theater while being distracted by adventure and popcorn? You could become an extra large drink for a bed bug.

Maybe the movie is enjoyed (or possibly slept through) in that favorite recliner in the living room. You could be a target.

Have a long cab ride into the office?

You get the idea. Any place that humans sit, rest or sleep can be a place that bed bugs are introduced or feed.

HOW DO BED BUGS SPREAD?

Bed bugs are consummate hitchhikers. In fact, they are primarily transported by humans and human belongings like suitcases.

If bed bugs or evidence of bed bugs are discovered, leave the area and call a qualified pest management professional to assist.

Bed bugs will move to other areas when they are disturbed. This may cause other areas to be infested that may be much more difficult to inspect or treat.

Do Earwigs Bite?

If you shudder a little when you think about earwigs, you’re probably not alone. They’ve developed quite a nasty reputation, thanks to urban legends (mostly false) that have been circulating for years. But are they harmful?

The Lifespans of Insects With Short Lives

Many insects, such as butterflies, have a lifespan that occurs in four stages: egg, larva, pupa, and adult. Other insects, such as grasshoppers, do not have a pupal stage and instead go through three stages: egg, nymph, and adult. The length of each stage can vary based on many things, from the insect species to the temperature outside—but what some insects share in common is a very short adult stage. Keep reading to learn about five insects with some of the shortest adult stages in their lifespan.

The Return of the Brown Marmorated Stink Bug

The change of seasons from summer to fall means many things: leaves changing colors, dropping temperatures, and—depending on where you live—stink bugs sneaking into your home. Stink bugs were named for their distinct ability to emit an unpleasant odor when they are threatened or disturbed by predators like lizards or birds. This also means that if stink bugs enter your home and feel threatened, you’ll be faced with dealing with their strong smell in your house. As we head into fall, you might find yourself with more active stink bugs than usual, so it’s important to know the basics about these smelly insects.

How to identify bed bugs?

Bed bugs are an oval shape and are up to 4-5 mm long when fully grown. Adult bed bugs have a flattened body and their skin colour is either rust brown or a deeper red brown.

Due to the flattened body of a bed bug they can easily hide in small places such as baseboards, cracks in floors, under carpets, behind loose wallpaper, bed frames, sofas, behind picture frames and many other places which makes them very difficult to detect. They tend to stay together and large infestations will give off a sweet but unpleasant smell.

What are some key signs of bed bugs?

If you suspect bed bugs, or want to be proactive, look for live or dead bugs or the skins they can leave behind when they are molting. After feeding, bed bugs will regularly leave behind small spots of reddish-black fecal matter on your bedding, mattress or box springs. They will lay their eggs (1/32″ to 1/8″ in size) in dark crevices near feeding areas.

Bed bug bites can also go unnoticed, and are even often misdiagnosed, making detection that much more difficult. Discover more answers to bed bug questions here.

Bed bugs spread

Once established, bed bugs tend to stay put but can spread due to any of the following;

  • Being disturbed (i.e. disassembling furniture or incorrect pesticide application)
  • A food shortage (i.e. no host) may cause them to migrate to neighbouring rooms
  • A shortage of harbourage spaces may cause them to migrate to neighbouring rooms
  • Infested furniture moved down a hall, or passed on to others
  • Vacuum cleaners used for multiple rooms
  • Commercial laundry machines

What to do if traces of bed bugs are found?

Do not

  • Disturb the room further. Leaving the “scene” untouched will help Orkin Canada diagnose the problem.
  • Take any items out of the room. Doing so will only help the bed bugs spread.

Do

  • Stop using the room and “quarantine” it
  • If the room is occupied, work with management to move guests to a new room
  • Contact a professional pest control company immediately in order to inspect the infested room and/or pre-treat rooms to which any guests might be moved. In British Columbia you can only pre-treat when evidence of an infestation is found.

How can I prevent bed bug infestation?

Look for live or dead bugs or their skins, Check beds for red spots of fecal matter, Clean and vacuum bedrooms regularly, Protect mattresses and boxsprings with certified bed bug encasements, Use light coloured sheets to spot stains, Check all furniture near sleeping areas, Look around seams, crevices, and folds, Seal cracks in walls, trim, and bed frames.

Since bed bugs are such good hitchhikers and often hide in hard to reach areas the best way to truly rid yourself of bed bugs is often professional pest control. Orkin Canada uses specially trained bed bug dogs, to detect anywhere live bed bugs and their eggs are hiding – and uses customized control strategies to make sure they’re gone for good.

Habitat, Diet, and Behaviour

What is the lifecycle of a bed bug?

Bed bugs undergo gradual metamorphosis (egg, nymph, adult). Nymphs are smaller versions of the adults and will go through several molts until fully grown.

Females lay 200 to 500 eggs in her lifetime, 10 to 50 at a time, on rough surfaces. Eggs then hatch within 6 to 17 days, with adult bedbugs having the ability to survive over 1 year without feeding.

Commonly Asked Questions

Why do I have bed bugs?

Bed bugs are seeing a resurgence in Canada and even the cleanest of homes can fall victim to these painful pests. At night, bed bugs feed on sleeping humans, but by day, they hide in dark undisturbed areas like inside furniture, baseboards, floorboards, carpets, and even wallpaper.

Bed bugs are attracted to the carbon dioxide and warmth that humans emit, which makes them particularly drawn to multi-unit buildings with lots of turnover like hotels or rental apartments, where they are often brought in on luggage or used furniture.

Bed bugs do not cling to people but they are notorious hitch hikers and can hide in our belongings (i.e. suitcase, purse, laptop bags). From there they can be introduced into a home, hotel, office, hospital, or any other building as well as modes of transportation. Sanitation is not a factor in whether or not you get bed bugs.

They are known to travel more than six metres from hiding in order to feed, but generally hide within two metres of their host, in large infestations that give off a sweet but unpleasant smell.

Why are bed bugs back?

Bed bugs never really left. They are common in many nations around the world. We are seeing a resurgence in North America for several reasons including a reduced use of pesticides, the use of second hand furniture and increased international travel as bed bugs are notorious hitch hikers.

The combination of re-introduction, increased international travel and the fact that pest control professionals no longer use older pesticides (such as DDT, Chlordane and Lindane) means that bed bugs have been able to stage a resurgence and become a very serious pest in the 21st century. They have a unique ability to hide and due to their ability to spread, new inspection and control methods must be far more thorough and extensive than with many other pests.

Bed bugs are parasitic insects that live near their hosts. Since they feed on humans (their hosts) their habitats include houses, hotels, or any property that we frequent. All they require is a protected area in close proximity to a feeding source. Bed bugs bite people when they are sleeping usually on exposed skin.

When looking for a meal bed bugs can move very quickly to feed and then back into hiding after their meal. Bed bugs have been known to travel over 20 feet from hiding in order to feed but will generally hide within 3-6 feet of their host. Unless you know specifically how to look for bed bugs these pests can be easily overlooked.

How worried should I be about bed bugs?

You may find red spots of fecal matter on your bed after being bitten by bed bugs, but it can be maddeningly difficult to detect where the bugs are actually hiding.

Bed bugs multiply quickly, with females laying up to 500 eggs in her lifetime. In just six months, a few of these pests can turn into a full-on infestation of more than 13,000 bed bugs. Adults can also survive for a year without feeding, so even if you leave, they might not.

When Treatments Don’t Work

If the goal is to eliminate bed bugs, the job has to be done correctly. Bed bugs are so small that they can live in a crack the width of a credit card, increasing the control challenge.

Pesticides often are an important part of a control strategy but they must be used properly for the treatment to work. There can be many reasons for failure of a pesticide treatment to completely control the bed bugs, including:

  • Not finding all the bed bugs.
  • Inadequately preparing area (failure to remove clutter, seal cracks and crevices, etc.).
  • Overlooking treatment of any of the known resting areas (bed bugs may rest or hide in hampers, bed frames, even furniture).
  • Failing to treat nearby areas where bed bugs may have migrated (adjacent rooms or other apartments in multi-dwelling housing).
  • Disregarding recommended label rates (applying pesticides at too low a rate may not kill bugs and may speed up development of resistance to that chemical).
  • Not following up on treatment in an appropriate timeframe (many pesticides will not kill eggs, so treatment must be repeated after the eggs hatch, or the infestation will not be controlled).
  • Not allowing enough time for a pesticide to work (some pesticides, such as drying agents or growth regulators, may be effective but take some time to kill the population).
  • Bed bugs becoming resistant to a specific type of pesticide.
  • As insects, such as bed bugs, are exposed to a pesticide over time, the most susceptible ones are killed first, leaving only the less susceptible ones to breed. This can result in a rapid decline in relative effectiveness of the pesticide.

Pesticide Resistance as a Cause of Treatment Failure

While there is evidence of resistance in some populations to certain types of pesticides, pesticide resistance can only be verified in laboratory tests. Researchers are currently trying to determine the scope of the resistance problem, which will vary from community to community. This research will support the development and use of effective control strategies.

Because of the potential for resistance, homeowners and others trying to control bed bug infestations must always use pesticides appropriately and according to the label. It is also important to:

  • be vigilant in surveillance, identification, and monitoring efforts;
  • hire trained, experienced, and reputable pest management professionals; and
  • use a comprehensive approach.

For example, you may wish to:

  • choose different types of pesticides from the list of currently labeled ones for sequential treatments; or
  • use pesticides for which insect resistance has not yet been reported, such as diatomaceous earth, in combination with other control techniques.

Remember, as illustrated in the list above, resistance is only one of many possible causes of a treatment failure. All possibilities must be explored in any situation.
