How Contagious Are Bed Bugs Person To Person

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.

They’re creepy, they’re crawly and they’re often quite difficult to spot. Bed bugs – blood-sucking, tiny parasites that dine on human and animal hosts – have become a concern worldwide due to their stealthy ways of getting around. Unfortunately, the little critters are more mobile than we would like to think.

Bed Bug Bites and Basics

Bed bugs – named for one of their favorite hangouts – tend to be found in linens, between cracks in mattresses and even in cracks and crevices in the floor. They leech off their human or animal hosts, with bed bug bites leaving scabby trails of rashes and marks across the skin. Because they are mostly active at night, it can take awhile for a person to notice that his home or hotel room has bed bugs.

How Bed Bugs Spread

Not everyone is aware that bed bugs can be spread via humans: if a person goes to a hotel room that has bed bugs, and the bed bugs hide out on the person or on the person’s luggage, the bed bugs can be spread to a new location. Because of this, no house is safe from a bed bug infestation. Bed bugs can spread from house to house, living in even the cleanest conditions; bed bugs are not a sign that a person’s home is dirty or unkempt.

Looking for Bed Bug Evidence

If you suspect that your home has been hit by bed bugs, look for the following telltale signs: small scabs or rashes in a line-like pattern on your skin, small fecal droppings or small blood smears on your sheets. The bed-bug bites will most likely be across your face, arms, or legs – the areas that are not covered by your pajamas as you sleep. Remember, though, that not all people will develop a rash if being bitten. You’ll also want to check for bugs in your mattress and in your luggage by closely inspecting them.

Eradicating Bed Bugs for Good

Though a variety of sprays and ointments are out there marketed as beg-bug killers, the truth is that many of these products do not work. You can attempt to rid yourself of these pests by vacuuming every inch of your apartment and by putting your linens in a dryer set on the highest setting. While it’s rare to find bed bugs on the clothes you’re wearing – they tend to fall off once you start moving – you should still wash any potentially contaminated clothing as well. A severe infestation will require the attention of a licensed exterminator; it can often take more than one visit from the exterminator to ensure that the bed bugs are really gone.

Are Bed Bugs Contagious?

Are Bed Bugs Contagious?

Bed bugs were once on the brink of eradication, but have made a resurgence in recent years. There are several possible reasons for this, including more travel by the average person, knowledge of the bugs falling out of public consciousness, and increased resistance to pest control methods.Regardless of the reason for the comeback, they are here.

This raises some questions about bed bugs: What are they,are they contagious, and how do you get rid of them?

Bed Bugs Are An Insect, Not An Illness

Since bed bugs are insects, you don’t exactly “catch” them like you would a disease or illness. They do, however, spread from person-to-person through various methods.

How Bed Bugs Spread

Bed bugs are parasitic blood suckers, who feed on living hosts.

But how do they get from host to host?

In several ways, but for spreading amongst humans, person-to-person contact is one of the least likely ways for bed bugs to spread. Unlike lice, bed bugs do not typically remain on hosts permanently.

Like their name would suggest, bed bugs can also live in bedding. It is commonly thought that hotels and motels (especially cheaper ones that are lax on cleaning) are rabid breeding grounds for bed bugs, but this is actually less true than most people think. One researcher investigated cases of hotels who had bed bug infestations and cleared them up. He was looking to see how long it would take for the bugs to come back, but they simply didn’t in the following 12 months. Not even in the case of one hotel that had served nearly 100,000 customers.

One of the more common carriers for bed bugs is luggage. This is because your suitcases and bags are frequently travelling, and let’s be honest: how often are they really washed?

Just How Easy Is It To Get Bed Bugs?

It really depends on the circumstances.

If your significant other picks some up while traveling, and brings them back to your bed? You will almost certainly get them.

If your coworker had them and you shake his hand? Almost no chance of transference.

Who Gets Bed Bugs?

Many stereotypes exist about bed bugs, with varying degrees of truth to them. One of the more prevalent is that poor or dirty people are more likely to catch or spread them.

Bed Bugs Hide in Fabric Folds

This is actually somewhat true. More so the “poor” aspect than the “dirty”, actually. It may seem insensitive to suggest that the poor are more likely to spread bed bugs, but research backs it up. Not only does low-income housing have a higher turnover rate, which means more people moving in or out, but the people living there are in less of a position to do something about an infestation.

Pathogens Carried By Bed Bugs (Or Not?)

It is often suggested that bed bugs are capable of carrying pathogens which are harmful to humans. I’ve even seen articles suggesting that there are up to 30 distinct pathogens that bed bugs can spread. This is not true, according to a report in the Journal of the American Medical Association. While bed bugs can carry certain pathogens in their bodies, they cannot spread them to humans.

To rephrase: There is little evidence to suggest that bed bugs spread disease or illness.


While bed bugs are notcontagiousper se, they can be spread from person to person through contact with clothing, bedding, or luggage.

Are bed bugs contagious?

Bed bugs can affect your daily life on several ways. Some of these affects are physical and some are psychological. But do they infect you any diseases and are they contagious?

What are bed bugs?

Bed bugs are insects which are parasites. So, they feed on living beings. Unlike other insects, their only food source is the mammalians. Bats, dogs, cats and human are their main food sources:

There are numerous insects in our houses. So, it’s important to identify a bed bug and what it looks like. We recently posted an article about what they look like:

Some distinct physical features of bed bugs are below:

  • They have oval-shaped and flat bodies
  • They have 6 legs
  • They are 1-5 mm length sized in average
  • Reddish-brown colored
  • Have no wings

Do bed bugs make you sick?

As we published an article about it before, bed bug bites will cause some health problems including itching, red spots, blisters and other secondary infections:

Common result of a bed bug bite is usually having some blisters at those points where they bit you. Itching and other infections come after that.

What u mean by contagious?

There may be two different meaning for the word “contagious”. One is about carrying diseases from one person to another and the second one is about moving from one place to another.

If you are curious about if bed bugs transmit some diseases from person to person, such an infectious case hasn’t been documented by any health organizations yet.

However, some studies claim that some diseases like yellow fever, HIV or plague can be transmitted by bed bugs, there is no any documented case in US.

But if you are curious about if bed bugs can move from one place to another or from one person to another; yes, it’s very possible.

How bed bugs move from one place to another?

Bed bugs can’t jump or fly so, they need a carrier to move away. It’s not difficult to move around in a house for bed bugs; but when it’s about travelling long distances, they can’t do it by themselves.

Some of their travel items are below:

Bed bugs are contagious at school or work

What makes them very contagious at work or school is that environmental control in such places are very difficult.

You can check every single person entering the school or office. You can’t control their bags, clothes or other personal staff.

So, when someone has bed bugs in personal staff like clothes or bag, bed bugs can move from one person to another one easily. Because they are so little in size and although they are visible to human eye, it’s difficult to see them while they are moving around.

How to prevent bed bug invasion at school?

However, it’s difficult to fight with bed bugs at school, there are some ways that can prevent bed bug invasion.

These steps can be taken by parents in such a deal:

  • Children infected by bed bugs must stay at home
  • All staff in the school must be checked carefully
  • There shouldn’t be unused clothes, boots or bags around
  • A professional pest control expert must be hired
  • Floor and hard surfaces must be cleaned with hot soapy water

Are bed bugs contagious to dogs or cats?

As I told above, bed bugs feed on mammalians by their bloods. So, they prefer to host in cracks or holes which are near to their food sources.

If there are bed bugs at home, they will probably try to feed on your pets like dogs or cats. But you must remember that bed bugs will always prefer human as the main and first food source.

This means that bed bugs can spread on your dogs or cats but, if there are human around and bed bugs can reach them, they won’t prefer feeding on pets.

What’s important about pets is that they are very good hiding places for bed bugs and a dog’s or cat’s hairy skin will become an ideal host for bed bugs.

How do Bed Bugs Spread? Are they Contagious? How Fast/Easily from Person, Room or House?

A couple of factors influence the spread of bed bugs from one place to another. Some individuals wonder of these insects are contagious. Here is an insight into how fast or easy they disperse and ways to curb it.

Are Bed Bugs Contagious? How do they spread from person to person?

Bed bugs are a big source of discomfort and embarrassment when you have them infesting your house or crawling on your clothing.

These tiny reddish or brown critters have been known to be the biggest infestations of households since centuries ago and comically have chosen where your best relaxation spots as they chill zones so as to get their blood meals.

They happen to be nocturnal based on their retreat in the light of day and tendency to wage wars in the night. During the day, they are able to hide from plain eye sight by selecting small and dark places

Bedbug infestation

It is worthwhile mentioning that bed bugs do not predominantly prefer your body as a hiding spot and this makes them hardly transferrable from one person to another through physical contact.

However, physical contact is relative as it is limited by time factor and the duration of contact between the source and recipient.

Their distribution is therefore dependent on the availability of a vector that should be able to allow the transfer of bed bugs from one person to another.

Such ‘vectors’ may include luggage, furniture and electronic gadgets.

Thus far, for an organism to be contagious, there should be an element of life on the host in which it relies on for its livelihood.

Notice that in the case of bed bugs, they do not live on the host’s body and therefore not contagious.

Inclusive of a time element of contact between individuals, then it can be logically supposed that you contracted bed bugs from person A and hence deemed ‘contagious’.

Indirect contact is the principal means through which bed bugs are transmissible from one person to another.

So how do bed bugs spread from one person to another through an indirect means?

To answer your question, you need to understand and identify the dominant hideouts of bed bugs in your household then pick out the items that may facilitate their transmission.

In households, bed bugs are able to hide in the following areas as referenced from the University of Kentucky;

  1. Box springs,
  2. Baseboards,
  3. Dressers,
  4. Mattresses,
  5. Bedding,
  6. Luggage,
  7. Closets,
  8. Electronics,
  9. Rugs,
  10. Carpets,
  11. Tiles on floors,
  12. Curtains,
  13. Curtain boards,
  14. Behind wallpapers
  15. Picture frames,
  16. Switches on walls

From your list above, you can be able to pick out the items that are mobile enough to allow transmission from person A to you.

You have probably picked out luggage, clothing in closets, electronics, picture frames, bedding of pets, purses and books. This list will never be exhaustive however.

Circumstances that may result in mobility of such items occur during travel when you do with your infested luggage, clothing or bus seat.

The latter is normally left out among vectors of transfer and measures to mitigate such transfers are occasionally put into context.

You might not have ferried many bed bugs, but a few of them could lead to a robust establishment in your residence that you may end up battling for the next decade.

How fast do bed bugs spread from room to room?

How do they spread from room to room?

When it comes to transfer of bed bugs from one room to another either in a lodging or in your own house once someone has brought some home, they may travel along the ceiling to other rooms.

Bed bugs have been observed to even fall from the ceiling to the bed making them one of the most cunny insects in the world. Fortunately for you, they do not fly!

How fast?

The speed at which bed bugs could mount an infestation depends on a number of factors that come into play either to promote or suppress its spread.

Such factors include the availability of an optimal condition or environment for its growth and the number of bed bugs that have been brought home.

Preliminary measures to preventing them perhaps set up before could also reduce the rate at which bed bugs spread.

This means that you might have set up some traps or covered your bedding or previously eminent cracks and fixed your loosely fitted sockets and switch plates, moves that avail very limited spots in which bed bugs can hide.

Therefore, this article will look at an ideal scenario where there is a provision for optimal conditions, physiologic reproductive capacity of bed bugs among other limiting influencers.

One good thing is that bed bugs could take long before they can actually start becoming a nuisance. Consider a scenario with a single female bed bug with the ability to lay about 100 eggs at least.

This would be perhaps in the first month and hence translated into infant bed bugs with an allowance of premature death, would make about 70 bed bugs.

This number would further translate into about ¾ of them developing and growing into adults. Therefore, by the second month, you will have about 35 bed bug adults that can mate and make more bed bugs.

It is almost assured that by the end of the third month, you will be hosting a colony of over 150 adults and more than a thousand developing nymphs.

At this point, the infestation has gone way overboard and you may need the assistance of professionals to help you treat it.

It therefore occurs as imperative that adequate measures be instituted in the second month before it may get any catastrophic.

According to Cornell College of Agriculture and Life Sciences, this number, by the sixth month may have increased in magnitudes of about 8-10.

How do bed bugs spread from house to house?

Bed bugs are transmissible from one house to another. Well, this depends on how the houses are built and spaced from each other.

Consider apartments in a block; such as observed in motels and lodgings or hostels in a university.

If the house next door shares a wall with the other on both sides and is infested with bed bugs, chances are they are breeding in the houses next door too and spreading.

There have been rampant cases of failing treatment of bed bugs infestation in apartments and hostels due to such loopholes.

In this case, spraying a single room may still allow bed bugs to escape into the next houses then come back when there is a ceasefire or equal measures instigated by the neighbor and it becomes a vicious cycle.

There are various ways in which bed bugs are able to travel from one house to another including:

  1. Travel through cracks and holes in walls
  2. Through ceilings
  3. Through spaces under the door
  4. Through pipes and other connecting systems
  5. Through sharing of furniture and other ‘vector’ materials.
  6. Visitations

Therefore, house to house transfers are quite hard to monitor and at times neighbors find themselves blaming each other for their infestations ending up in a ‘chicken or egg’ scenario.

How easily & long does it take for bed bugs to spread?

How long for them to spread? What factors will determine the duration an ease. Spread of bed bugs once they have been brought to your house will depend on whether:

  1. If a female bed bug, has mated.
  2. If a female bed bug, has a male partner for them to mate
  3. There are optimal conditions including temperature relevant for its growth and development
  4. Its hide-outs are well placed for breeding and retreats.
  5. You will instigate measures to treat and impending infestation
  6. A vector material is available for its transmission.

Hence, such factors are influential in determining the rate, extent and ease of spread of bed bugs.

How to control the Spread

It is important that you always have measures that will help you prevent spread of bed bugs.

This is regardless of whether you have them and would not want them spreading into your neighbor’s house, spread from your travel accommodation to your own house or reducing the rate of spread among rooms in your own house. You can consider the following tips:

Inspect your clothing before wearing them:

Since bed bugs can hide in between your clothing in the closet, it is necessary to ensure that the clothing you choose for the day isn’t ferrying any bed bugs.

This, you can do through physical inspection especially along the corners of sections sewn together and thoroughly doing so for dark colored clothes.

Iron the clothes thereafter paying keen interest on the corners, sleeves, collars and edges of your shirt, blouse or trousers. Shoes, socks, scarfs and caps are also possible areas in which bed bugs can hide.

If you have a dryer, you can heat your heat-stable clothing for about 30 minutes. If you do this a night before, you can insert the clothes in a plastic bag and seal it so that they are ready to wear on the following day.

Once you are dressed, leave without having to sit on the bed or furniture otherwise they might just crawl back onto you. Do so for your purse, had bag or brief-case.

Inspect your purse, wallet and bags

Do this frequently so that you are able to take out everything that you have in the bag and clean it. Cleaning could involve washing it, allowing it to dry then heating it in a dryer for a few minutes.

Flip through the pages of your books too as they could be in there. Other ways in which you can clean your bags, which happens to be less cumbersome includes vacuuming or brushing them.

Above all, once you have a clean bag devoid of bed bugs, seal them in a plastic bag.

Traveling anti-bug measures

Choice of accommodation is important to ensure that you sleep in rooms that have been frequently treated. While bed bugs have been rampant for motels and lodgings, even quite lavish hotels are beginning to indicate that bed bugs do not choose their blood meals.

Therefore, do not assume that since you are in a posh hotel, you are safe from bed bugs. Hang your bag on the hook instead of having them on the bed or on the floor.

Ensure that you inspect the corners of your bed and the mattress on which you are going to use and make a call for changes if you notice any danger signs.

Once you get home, leave the bags outside and only let them in when you have treated them if you are from an area with an infestation.
