How Can Bed Bugs Come In Your House

What Causes Bed Bugs? 6 Ways They Find A Way Into Your Home

The first step in knowing how to get rid of bed bugs is to figure out what causes bed bugs. By knowing the ways in which bed bugs come into your home and lay eggs, you can take steps to prevent a bed bug infestation in your home.

Contrary to popular belief bed bugs are not caused by filth or poverty. Bed bugs do not care that you’re rich or poor, clean or messy. They are concerned with blood of humans and animals and nothing more. Every home is susceptible to bed bugs so your best bet is knowing what caused them so you can prevent and treat them.

Pets

Bed bugs can be brought into your home by household pets like cats and dogs. They are warm and have blood, making them the ideal ride into your home. Since bed bugs are not necessarily ‘inside’ creatures, they often hop on animals to feed and simply end up in a new location as the animal moves around.

Pets are just one cause of bed bugs, but regular bathing can minimize a bed bug infestation.

Cramped Living

Cramped living quarters such as hotels, college dorms, hostels and apartment buildings are a big cause of bed bug infestations. While it is not the fact that much of the world lives in apartments or other forms of cramped living, living close to your neighbors provides a good way for bed bugs to spread.

For example, living in an apartment building or dormitory where one unit has bed bugs can quickly cause others to have bed bugs as well. They travel on the carpet from one unit to the next, in the air ducts and power outlets. When one person gets bed bugs in cramped living quarters—particularly without alerting their neighbors—they cause others to get bed bugs.

If you notice bed bugs in your apartment, quickly alert your neighbors so they may prevent or treat their own infestation.

Traveling

International travel has certainly increased our awareness of bed bugs because placed like hotels that have a high turnover rate of human activity. Even a five star hotel can cause bed bugs in your home if that is where the bed bugs latched onto your luggage or clothing.

Places like hotels and airplanes where there thousands of people sharing the same small spaces are a breeding ground for bed bugs. Any place where people are sitting or sleeping for long periods of time is a place that can cause bed bugs to hitch a ride home with you.

Used Furniture

City dwellers often rely on city services to dispose of used furniture, generally by placing old furniture on the curb for a pick-up service. Many times the furniture is picked up to be used by someone else before the pick-up service arrives, and this is one of the causes of bed bugs in your home.

Even if the previous owner had no signs of bed bugs in their home, they can be transferred to the used furniture just from a few minutes on the street.

If you love free furniture, be sure to clean it thoroughly or risk a bed bug infestation.

It isn’t just used furniture found on the street. Used furniture found at flea markets, outdoor sales or second hand furniture shops can also bring bed bugs into your home.

Cracks & Crevices

If you have noticeable cracks or crevices on the walls, floors or ceilings in your home, this is a simple way for bed bugs to crawl into your home. Since bed bugs are quite small they can enter through even the smallest crack in a wall.

They seek warmth and those cracks and crevices provide them an easy way into the warmth.

Your best bet is to seal these cracks as soon as you spot them. Don’t wait until you need to do one big job to buy caulk. The sooner you seal those cracks the greater your chances of avoiding a bed bug infestation.

Clothes

The clothes on your body can easily answer the question,what causes bed bugs?Anywhere you go that has bed bugs—knowingly or unknowingly—is a place where you can bring them home with you.

If you suspect that you may have come in contact with bed bugs immediately run your clothes through a wash cycle on hot water. This will kill the bed bugs before they can lay eggs and infest your home.

Keep in mind that these are just a few of the causes of bed bugs. Regularly check your clothes, pets and furniture for signs of bed bugs. Seal up the cracks and crevices you notice and keep the bed bugs at bay.

What Attracts Bedbugs to Human Environments?

  • B.A., Political Science, Rutgers University

Once considered a pest of the past, bedbugs now make regular headlines as they infest homes, hotels, and dormitories worldwide. As bedbugs spread, more people worry about them and want to know what causes a bedbug infestation.

Though it might seem as if bedbug infestations are on the rise, historical context indicates that bedbugs and other bloodsucking parasites have been associated with humans for thousands of years. Throughout that history, people have endured them feeding on their blood. Bedbugs all but disappeared when people started using DDT and other pesticides to keep insects out of their homes. Although news headlines suggest bedbugs are conquering the world, the reality is that bedbug infestations are still at historically low numbers.

Why are they called bedbugs? Once they settle into your home, they congregate where you spend a lot of sedentary time: chairs, couches, and especially beds. They are attracted to you by the carbon dioxide in the air you breathe out, and you do a lot of breathing over the hours you’re in bed. Then they feed on your blood.

Bedbugs Don’t Care If You’re Clean or Dirty

Contrary to popular belief, there is no association between bedbugs and filth. They feed on human and animal blood, and as long as a source of blood is available to them, they will happily take up residence in even the most pristine home.

Being poor doesn’t put you at greater risk for bedbugs, and having wealth doesn’t immunize you from a bedbug infestation. Although poverty doesn’t cause bedbugs, impoverished communities may lack the resources needed to control infestations, making them more persistent and pervasive in such areas.

Bedbugs Are Excellent Hitchhikers

For bedbugs to infest your home, they have to hitch a ride on someone or something. They don’t usually stay on their human hosts after feeding, but they might hide in clothing and inadvertently go along for the ride to a new location. Most often, bedbugs travel in luggage after someone has stayed in an infested hotel room. Bedbugs may even infest theaters and other public spaces and spread to new locations via purses, backpacks, coats, or hats.

Bedbugs Go Where the Action Is

Since bedbugs travel by hitchhiking, infestations are more common in places with high rates of turnover in the human population: apartment buildings, dormitories, homeless shelters, hotels and motels, and military barracks. Any time you have a lot of people coming and going, there’s an increased risk that someone will carry a few bedbugs into the building. In general, owners of single-family homes have a lower risk of getting bedbugs.

Bedbugs Hide in Clutter

Once in your home, bedbugs scurry quickly to select a new hiding place; in beds and other furniture, behind baseboards, under wallpaper, or inside switch plates. Then it’s just a matter of time before they begin multiplying. A single female may arrive at your doorstep already carrying enough eggs to produce hundreds of offspring. While filth does not benefit bedbugs, clutter does. The more cluttered your home is, the more hiding places there are for bedbugs and the harder it will be to get rid of them.

What Causes Bed Bugs

Bed bugs often appear even in new apartments that are equipped with the all modern conveniences. Certainly, the owners of clean houses are puzzled about why parasites have inhabited their apartment. Moreover, how have they penetrated into their dwelling? There are several causes of bed bugs appearance in the apartment.

The thing is that it does not matter how carefully cleanliness is maintained. The main and the only target of bed bugs is a human being (or sometimes small-sized animals). Thus, they can settle in the places where people spend nighttime.

To avoid bed bugs penetration into the house you should always stay alert and monitor the subtle changes that happen in the apartment. Also, from time to time it is useful to take prophylactic measures and apply insecticide on the perimeter of the possible entry points of insects. It is also recommended to communicate with your neighbors and pay attention to the condition of their apartments.

Additionally, bed bugs can come to your house by chance. In this case, it depends on the owner’s wish to mind all the possible ways of their penetration. Therefore, it is important to understand what causes bed bugs appearance to be able to protect yourself from these parasites when needed.

What Causes Bed Bugs in an Apartment?

It is difficult to answer the question about where bed bugs come from. It depends on the flat location, the presence of parasites at neighbors’ apartments, or the owners’ recent trips by train or someone else’s car. There are many ways of how these insects penetrate into the house; thus, bed bugs causes may be different.

  • In most cases, bugs come from neighboring premises. It is especially typical for old buildings. Insects can crawl through a damaged wall, cracks or the outer wall of the house. Also, bed bugs often come through ventilation shafts. They can survive without food for quite a long time. Thus, long travels are not a problem for them. Insects’ body shape and small size facilitate their penetration into small holes and cracks. If a house is located in the countryside, bed bugs can often come to people from small-sized farm animals. In fact, the thick skin of a rabbit or a goat is not so attractive to these blood-sucking insects as the human one.
  • You can “catch” a bed bug and transfer it to your apartment having spent a night outside your house. Hotels, friends’ apartments, as well as trains or railway stations are places where you can get these parasites. Bed bugs are small in size. Thus, even if an insect does not have time to hide when a person gets up and dresses, the bug’s presence will be unnoticeable on the cloth.
  • One more cause of bed bugs penetration is buying appliances. Bed bugs like to hide in the places that are protected from bright daylight and have a source of heat. Parasites often get into working system units. If such a unit is moved to be repaired or to a new apartment, bed bugs will quickly spread through a new place.
  • Another way of getting bed bugs is bringing them to the house on clothes. Parasites cannot bite through clothing, but they can hide in it. It is not always possible to notice the bloodsucker due to its tiny size. Therefore, it is very likely to bring one or more insect home, having visited an apartment inhabited by them. Also, another cause of bed bugs penetration can be a purchase of clothes infested by these parasites.
  • Furniture is one of the most common bed bugs causes. New pieces of furniture brought from the store are rarely infested, as parasites simply have nothing to eat there. However, exceptions may occur. In most cases, bed bugs can dwell in the furniture that was previously used. Parasites spread through its surface and cracks. It is necessary to check the furniture very carefully before buying it, especially the inside part of it.
  • Bed bugs can live on bats, birds, hamsters and rats if they have not very long and thick hair. These insects do not drink blood of cats or dogs because their skin is too thick for these parasites. For this reason, they prefer cattle.
  • Guests may bring bed bugs to the apartment too. People who live in the infested premises may bring these insects on their clothes. It happens that after flat renovation owners may reveal bugs “left” by workers. These parasites are very fond of the large crowds of people, so they often live in construction trailers and hostels. If hired workers live in such conditions, it is very likely that they will bring bed bugs to their workplace.

What Causes Bed Bugs?

Bed bugs aren’t caused by dirt and filth and they’re not a holdover from some deadly plaque from years ago. They exist solely because of us—and they’re out for blood.

The first thing to understand about bed bugs is that their only food source is blood. The common household bed bug needs to feed on human blood both to live and to breed. So what causes bed bugs is essentially… us.

Bed bugs don’t have the ability to leap or fly, so to get close to their food source they hitch a ride on us and our belongings. Once they’ve arrived at their destination, they seek out places where we humans nap or sleep, they hide out, and they wait. Bed bugs are able to sense, by body heat or the carbon dioxide we emit when breathing, when their human host is asleep, then they quietly crawl onto our skin and settle in for a blood meal.

Some of the most common causes of bed bugs are:

  • Travel
  • Population growth
  • Urban living

Why am I hearing more about bed bugs now?

Bed bugs were nearly wiped out in the 1950s by the pesticide DDT. But in 1972, DDT was banned because it was found to be dangerous to humans, wildlife, and the environment. Bed bugs are hardy insects, and the ones that survived did so because they were resistant to DDT (and other pesticides). These super bed bugs kept living and breeding—each female can lay three to five eggs per day and hundreds in her lifetime, depending on conditions.

Their resistance to pesticides combined with increasing ability to spread via global travel, population growth, and urban living contributed to the resurgence that has occurred in the United States. Today, “one out of five Americans has experienced a bed bug infestation or knows someone who has encountered these pests,” says Brittany Campbell, PhD, an entomologist with the National Pest Management Association (NPMA).

Do bed bugs live on people?

No; for the most part, the only time bed bugs are on humans is when they’re feeding, but they do rely on us to get around. “Bed bugs travel with us, so however we may travel, they will travel,” says Jody Green PhD, an urban entomologist at the University of Nebraska—Lincoln.

“They do not have wings or specialized legs for jumping, so they crawl onto our belongings to hitch a ride.” And they’re not picky about their mode of transportation—backpacks, luggage, purses, car seats, wheelchairs, wigs, toys, and sleeping bags are all common forms of transit for bed bugs.

Can bed bugs travel the globe?

Yes, and travel is a big factor in what causes bed bugs. “Global travel has increased exponentially in the last several decades, as it has become cheaper and more accessible for a wider percentage of the population,” says Eric Braun, a board-certified entomologist for Rentokil Steritech, a pest control company. “That has made it much easier for bed bugs to hitchhike and move on personal items, planes, ships, and people.” If you travel a lot, you definitely want to know how to spot bed bugs in your hotel room.

Do bed bugs like cities better than rural areas?

Bed bugs aren’t partial to any particular locale; they will make a home just about anywhere they find us. What causes bed bugs to choose a location is based on how and where humans live. “In the last several decades, North Americans have become increasingly urbanized, moving closer together in cities. The closer we live in proximity to one another, the easier it is for bed bugs to spread,” says Braun.

Can I bring home bed bugs from a thrift store?

It’s hard to pass up a good deal on a nearly new sofa, but before you buy it, consider what could lie in its folds and crevices. “That sofa could harbor bed bugs or bed bug eggs, which might not be observed immediately,” Braun cautions. Be vigilant and inspect furniture thoroughly before bringing it into your home.

How far can bed bugs crawl?

Bed bugs are champion crawlers and move quickly. “Over the course of a night, they could find their way down a long hallway,” says Braun. Plus they can survive without a blood meal for 6 to 12 months, Green says, which is part of the reason they’re so hard to spot and get rid of.

Can bed bugs live in cold climates?

“Climate does not affect bed bugs because they live with us in our homes and we keep it at the optimal temperature for both us and them,” says Green. Do chilly temps kill bed bugs? Only under the right conditions. According to Green, the temperature has to drop to 0°F for four days to kill a bed bug. So bed bugs could survive a while in your car before hitching a ride into your house. That’s why you’ll want to know the telltale signs of bed bugs in your car.

Is getting bed bugs inevitable?

Green offers this helpful analogy: “Think of bed bugs like germs. We carry germs around; they need people to survive, but sometimes we leave germs in places, and other people pick them up and get sick. All people are exposed, everyone can get sick from germs, but not all people do get sick. Not every case is the same, but all cases can be preventable with awareness, communication, and education.” Knowing these 16 secrets about bed bugs will help you to keep them at bay.

Where Do Bed Bugs Come From – How Do You Get Bed Bugs

How do you get bed bugs in your house? Anyone who has ever woken up with a chain of red blisters from the bites of night parasites would wonder where bed bugs come from. In most cases, bed bugs are not transferred to the apartments. The thing is that they live there for decades, not revealing their presence at once. Mostly these insects spread from one apartment to another, but where do bed bugs come from?

It is impossible to answer this question because they just spread through the building being attracted by the presence of humans. How do bed bugs get in bed? After penetration into the premises, insects hide under the beds, in the wardrobes, under the carpets, behind the baseboards, in the cracks of furniture and in mattresses. These insects prefer to settle in places where they can bite people during night time.

In suburban areas bed bugs find human dwelling using their sense of smell. Then insects move to the buildings from chicken coops and rabbitries, where they parasitize on the skin of medium-sized animals. However, bed bugs parasitism on other mammals and birds is more like an exception, because these insects usually feed on human blood.

Bed bugs are not very mobile insects. They cannot fly and run much slower than cockroaches, but they can survive without food for quite a long time. Thus, bed bugs can travel for long distances. How do bed bugs spread? Despite the fact that these parasites cannot run fast, they spread through the apartment considerably quickly. They move freely through ventilation holes, electrical wiring channels and cracks in doors. Due to flat shape of their bodies these insects are able to crawl even where no cracks or holes are visible. It is impossible to isolate an apartment from bed bugs because they come through the outlets and by the outer walls through the windows. It is especially true for the apartments in old high-rise buildings and the houses built in the countryside.

How Do You Get Bed Bugs in Your House

First, people get bed bugs by bringing them home from journeys. For example, bed bugs can be in the luggage and the things brought from the trips, to the warm countries in particular. Tropical Egypt, Thailand, Indonesia and India seem to be a paradise for thermophilic bed bugs. Thus, travelers have to remember that the last place they traveled to before the bugs appearance is the most likely to be a historic homeland of the blood-sucking parasites. In this case, you can bring a single adult female that may lay eggs and give rise to a new population. You should be cautious because these insects can hide or accidentally fall into the pleats of the clothes, into the suitcases, bags and footwear, and travel through several time zones. This way of getting bed bugs is particularly relevant for backpackers, who often change hotels.

One more common method of how bed bugs come to the new house is hiding in the furniture, especially in the new one. In furniture factories or stores bugs have nothing to eat; thus, new products are not infested. Pieces of furniture from infested houses and apartments are, on the contrary, the main breeding ground for these parasites.

People can also get bed bugs on clothes. Although these insects prefer to bite open skin areas, they often hide in the clothes left in the apartment or taken off before going to bed. Thus, you can bring bugs into your house by visiting the infested house or taking guests from such a place. Moreover, there are known cases when bed bugs were found in expensive clothing shops in unworn clothes. The insects got there from people who lived in the infested apartments or from neighboring premises.

Furthermore, bed bugs can get into the house with new appliances. These insects prefer to spend the daytime in warm places. Thus, they can stay in laptops, tablets, scanners, microwave ovens, and any other appliances, and be transferred to a new place from the store.

Moreover, bed bugs can get into the apartment being carried by animals. It is a very rare way of transferring these insects, but it may happen too. Despite the fact that bed bugs do not feed on cats and dogs because they cannot bite their skin tissue, these pets can transfer the parasites. Moreover, bats and birds can be transmitters of these parasites as well.

Thus, once appeared in the house, bed bugs can spread through the entire apartment. They can inhabit all the places where they can be caught only by the professional desinfectants. Moreover, bed bugs can fall into anabiosis because of the absence of food. Thus, the bugs can stay in uninhabited apartments for more than a few months. A flat can be perfectly clean at first glance, but insects and their larvae will crawl out of the cracks as soon as they smell a human body.
