How Do Bed Bugs Grow

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.

How Fast Do Bed Bugs Grow?

Bed bugs feed on humans while they’re sleeping. These pests can be found in almost any area where people congregate including houses, hotels, offices, and stores. Since bed bugs can become a major pest control issue, you may want to know how quickly bed bugs grow.

Bed Bug Pattern

Bed bugs can easily hide behind cracks, box springs, baseboards, and folded areas of beds. These insects consume a blood meal during the day and it typically takes five to 10 minutes to gulp down the blood. After they’ve fed, they maneuver to isolated spaces where they hide for five to 10 days. Throughout this lifecycle, they do not get fed. This is the time for them to digest their meal, mate, and lay eggs.

Preventing Bed Bugs

There are various ways that you can prevent bed bugs. Make sure that you check your bed sheets for blood spots and refrain from bringing home used furniture such as box springs and mattresses without completely inspecting for signs of bed bug infestation. If you have pets, routinely examine the areas where they sleep for signs of bed bugs. It’s wise to obtain a home inspection report in Atlanta, GA, if you’re in doubt.

What Happens Once Bed Bugs Are in Your Home?

As soon as bed bugs enter your home, the infestations can take a few months before it becomes a major issue. One female bed bug who has already mated can populate your home with additional bugs. The female will lay approximately 100 eggs within the first month. By the end of the month, there will be about 60 developing infant bed bugs and another 40 eggs. There are various home inspection rates in Atlanta, GA, for getting rid of these bugs.

How Fast They Spread

At the end of month two, the population grows to 10 breeding adults with many eggs and 200 developing bed bugs in various stages. At this time, you may observe small, reddish-brown colors and dark specks of dirt on your bed sheets. In the third month of infestation, the population flares up. There will be a community of 100 breeding adults, about 500 eggs, and thousands of developing bugs. Additionally, some of the bed bugs will begin to maneuver to other rooms in your home. Within the first six months of a pregnant female bed bug entering your home, it’s very possible that you will have an infestation in every room. By this point, the population has grown to more than 8,000 breeding adults, about 60,000 eggs, and tens of thousands of developing bugs. With infestations, it’s best to contact a professional pest control service. You should obtain a home inspection quote in Atlanta, GA, prior to hiring anyone.

A home inspection service in Atlanta, GA, is done by an individual who is licensed to perform inspections to determine the possibility of damage caused by bugs, insects, or termites. Most of the products used by pest professionals are very effective and the chemicals are considered to be safer.Home inspection prices in Atlanta, GA,can vary.

Bed Bug Life Cycle

Bed bugs are nocturnal, reddish-brown insects that feed on the blood of humans and other warm-blooded animals. These wingless insects have dorsoventrally flattened bodies that allow them to hide in areas such as floor cracks, carpets, beds and upholstered furniture.

A bed bug’s life begins with an egg, grain like and milky white in color. Female bed bugs lay between one and five eggs each day and may lie up to 500 eggs within one lifetime. Eggs are laid singly or in clusters and are placed within tight cracks or crevices. The egg is approximately 1 mm in length and is comparable in size to two grains of salt. Within two weeks, eggs hatch and immature bed bugs begin immediately to feed.

Nymphs

These young bed bugs, or nymphs, pass through five molts before reaching maturity. Although nymphs appear similar to adults, they are smaller in size and are not yet sexually mature. Young nymphs are also yellow-white in color, while older nymphs and adults are reddish-brown. In order to complete a molting stage, each nymph requires a blood meal. At room temperature, nymphs molt and become adults within five weeks.

Adults

Upon reaching maturity, bed bug adults often make weekly feedings.


Adult Bed Bug

How Long Do They Live?
The life span of a bed bug most commonly ranges from four to six months. However, some bed bugs may live up to a year under cool conditions and with no food.

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.

How Long Can Bed Bugs Live Without A Host? (A Simple Answer)

​Bed bugs are a very frustrating problem for lots of homeowners especially across many states in the United States.

Their excellent adaptability to a wide range of climates and their rate of reproduction have earned these parasites a notorious reputation throughout the country.

Because they get bitten every night by these nasty and stubborn parasites, a lot of homeowners are drawn into the wrong conclusion that leaving the house for a few days can starve the bed bugs to death or at least force them out of the property in search for a new host.

But does it really work?

​The bed bugs’ ability to survive without a host depends on a number of factors. And understanding these critical elements can help you land on the ultimate answer to the question.

​How Does A Bed Bug Feed?

​Before we can really answer the main question, it is best that we first take into consideration how a bed bug feeds.

As we all now know, bed bugs don’t have a chewing mouth part that help them burrow deep into our skin. Instead, these parasites are equipped with a needle like proboscis which they use to pierce through our skin and into the nearest blood vessel.

Prior to feeding, the bed bug excretes an ample amount of saliva which acts as an anesthetic component. It numbs the nerves of the skin surrounding the target area so that the victim doesn’t feel a thing. The be bug’s saliva also acts as an anticoagulant which helps keep the blood flowing as it feeds.

​Is Blood The Only Type Of Meal bed Bugs Prefer?

​Yes. Blood is the only type of nourishment bed bugs require and accept. They can’t and will not feed on anything else other than a thirst quenching blood meal.

Bed bugs need blood for them to molt and to develop full sexual maturity. Proteins and other nutrients found in their host’s blood is essential for the development of their eggs.

The following video is a close up documentary on how a bed bug bites and feeds.

​A blood meal from a human host is what bed bugs prefer. These nasty buggers are significantly attracted to us because of the heat signature that our bodies give off and the carbon dioxide that we exhale. But in the absence of a human host, bed bugs acquire blood meal from animals nearby.

​How Often And How Long Does A Bed Bug Feed?

​When an egg hatches, a nymph emerges. This nymph requires at least one blood meal to molt into the higher stage of its life. The nymph undergoes several molting process (less than two months) before it reaches full maturity.

Nymphs usually take about 5 minutes to feed. Adults on the other hand, may take around 10 minutes per feeding session. It then retreats to a safe spot for digestion of the blood meal it has acquired from its host.

Both nymph and adult bed bugs feed only once per week. If you get bitten by these critters every night, it simply means that you have a sizeable bed bug population to deal with.

​How Long Can A Bed Bug Survive Without Feeding?

​Basically, bed bugs can survive from several months to a full year without a host. But this survivability directly depends on a few factors.

​Adult bed bugs can survive longer compared to the younger ones or nymphs. The absence of a host for a blood meal doesn’t hinder the nymphs from developing into full adults.

Rather, it drastically decreases the amount of time needed for nymphs to reach full maturity. Nymphs become adult bed bugs in just about a month resulting to significantly weaker insects.

Temperature of the direct environment also plays a crucial role on how long a bed bugs survives without a host. Under normal room temperature, adult bed bugs can linger for a year. Increased temperature on the other hand, remarkably decreases the total length of time a bed bug can survive without a host.
