How Long Do It Take For Bed Bugs To Spread
Preparing for Treatment Against Bed Bugs
Whether you are hiring a pest management professional or trying to eliminate the bugs yourself, properly preparing your home is an essential first step. Taking these steps before starting out will help speed the process and reduce control costs.
Reduce Clutter–a Great Hiding Place for Bed Bugs
- When reducing clutter take care that you don’t spread the bed bugs:
- Don’t move items from the infested area to a non-infested area.
- Place trash or other infested items directly into plastic trash bags. When full, immediately carry the bags to an outside bin.
Make Your Bed an Island
- Move the bed at least 6 inches away from the wall.
- Ensure all bed bugs, larvae, and eggs are removed from the bed, frame and headboard.
- Place bed-bug-proof covers (often called encasements) or liners on your mattress and boxspring (available in home stores or online).
- Take care that these covers have zippers that close completely and that they are sturdy enough to last for a year.
- Any bed bugs trapped inside will eventually starve to death, and other bed bugs won’t be able to hide in the bed or box spring.
Clean All Items Within a Bed-Bug-Infested Living Area
- Heat treat clothing, bedding, and other items that can withstand a hot dryer (household dryer at high heat for 30 minutes), which will kill bed bugs and eggs.
- Washing alone might not do the job.
- Store clean items in a sealed plastic bag to ensure they remain bug free
Eliminate Bed Bug Habitats
- See "reduce clutter."
- Caulk cracks or crevices around baseboards.
- Repair any wallboard damage, ensure wallpaper is not loose.
- Check electrical outlets and wall switches for evidence of bed bugs.
- Clean if needed.
- Tape or caulk the rims to prevent bed bugs from getting behind the plates.

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.

Do Bed Bugs Travel on People?

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.

Learn About Bed Bug Infestations So You Will Be Better Equipped to Fight Yours!
A bed bug infestation is a big deal. It can disrupt your sleep/life, and you may have no idea what is happening to you or how to stop it. Bed bugs are different from most other household insect pests and are much more difficult to live with and to get rid of.
Bed bugs are keen to find a way into your house, and you have to be aware of their “migration tactics” in order to thwart them. You need to know how they move from house to house and room to room, how fast they can spread, where they are likely to hide, and what options you have for killing them.
Make no mistake. A bed bug infested home means your home has just become a war zone. You can’t let the enemy sneak by unnoticed under your radar, and knowing the facts about bed bugs is winning half the battle.

Where Do Bed Bugs Come From?
Bed bugs are quite willing to enter your premises uninvited, take up permanent residence, and help themselves to a blood feast. But where do they come from to begin with?
The fact is, bed bugs live primarily in human habitations all over the world, be it in mattresses, box springs, carpeting, picture frames, cracks in floor, furniture, or a host of other locales.
Of course, bed bugs ultimately hail from the great outdoors, and you may find some still living there in tall grasses, but they are overwhelmingly an “indoor insect.”
Transferred from Person to Person
Unlike fleas and lice, bed bugs do not tend to live permanently on human beings or animals. Instead, they will generally hide is some hard to reach nook or cranny and come out at night to feed. That’s why they like to live in or near beds and other places people sleep or sit for long periods.
But, it is still possible for bed bugs to be transferred from person to person.
- They can get into your clothes, purse, laptop bag, jacket, or anything else you wear or carry about.
- From there, they can get onto clothes of others you are in close contact with.
Their eggs can also be found on clothes sometimes, and if egg-infested clothes of yours touched someone else’s clothes, even the eggs could get transferred.
So, while it’s not very likely, it is possible for bed bugs to move from person to person.
Spread From House to House
Bed bugs, as clever as they are, do not generally walk long distances between buildings. They have other ways of getting into your house.
These stealthy home-invasion strategies include (but are not limited to) the following:
- Hitch a ride on your laundry, luggage, or other possessions that you bring back from a bed-bug-infested hotel room.
- Your pet might pick up a bed bug while visiting another house (or even outdoors) and then bring it back to your place.
- Bed bugs may be hiding in furniture in one house, but the owner may sell it at a garage sale or put it on the curb to dispose of it. Then, you take that old bed-bug-ridden piece of furniture into your house, thinking it’s a great find.
- You sleep over at a friend’s house where bed bugs live. Bed bugs get into your stuff or on your person, and you unknowingly transport them home with you.
- If you live in a multi-unit home or apartment complex, these bugs can crawl down the hall, through vents, and through cracks in the walls to get into your living quarters.
Spread from Room to Room
You may, perhaps, imagine that bed bugs can’t get around too fast. It’s true they have small legs and can’t hop or skip, but they can walk up to 100 feet in a single night. They just “keep going till they get there.”
Bed Bug Hiding Spots
And bed bugs are known to move through the inside of walls, which they will access via outlets if not through cracks. They can run inside of in-wall piping for a quicker move from room to room. It really doesn’t take more than a single night for them to migrate to a new room. And they can even get into your vacuum cleaner so that you are helping them spread quicker as you clean the carpet.
It could be a matter of days before your entire house is infested, given you have enough of a bed bug population and your bed bugs are motivated to look for food/water/blood somewhere other than where they are at the moment.
I found a bed bug, you say, so where should I look for more? Can I map out the infestation so I can map out an eradication plan?
Unfortunately, there’s no way to be sure of all the nooks and crannies your unwelcome guests may be hiding in, and they may even move around from night to night. All you can do is know the likely spots and apply bed bug killer.
I Have One Bed Bug. Does It Mean an Infestation?
A single bed bug may or may not indicate you already have a true infestation.
But if you do find a bed bug, here are some things to keep in mind:
- A single impregnated female can produce a whole population. She will lay the eggs and then breed with her own offspring.
- The odds are in favor of your not having found the only bed bug in your house. Where there’s one, there are probably more.
- Bed bugs can go 6 months or more without a blood meal, and many individual bugs may not feed more than once a week on average. Thus, you won’t see them all out searching for food at the same time.
- Is the bed bug red-bodied? Then it was feeding. If they’re feeding, chances are they’re breeding.
Once in your bedroom, bed bugs will have no trouble finding your bed. They are attracted to carbon dioxide such as warm-blooded animals exhale and to your body heat. As soon as they sense CO2 and heat at night, they will go to your bed because you, their target, are lying on it.
Bed bugs can get into your bedroom on your dirty clothes, on the clothes you are wearing, or by hiding in suitcases, hand bags, boxes, furniture, or anything else you bring into your room that offers them good cover.
Do bed bugs live in walls? The answer is: sometimes. Walls are not necessarily their number one or preferred hideout, as with cockroaches, but when no better shelter exists near their feeding zone, they’ll be quick to reside inside wall cavities.
Of course, there has to be an entry point for them to get into the wall. So if your walls have cracks or small holes in them, caulking it up, painting over it, or otherwise sealing it off may deny your bed bugs a hideout.
Yes, bed bugs can live inside wood flooring. They can even crawl along inside the seams between wood planks, even when those seams are rather tight.
The pancake-flat bodies and small size of bed bugs allow the to get into and live in even the most inaccessible areas. There are few wood floors, if any, that are so tightly put together that bed bugs couldn’t get into them.
You may be wondering what to do if you have bed bugs, and how long you have before they overrun you. You may be waking up at night, staring at the clock, and wondering, “How long do I have?”
How Long Does It Take for Bed Bugs to Infest?
Here are four facts you should know that will give you an idea as to how long it takes for a bed bug infestation to get started and to get into “full swing:”
- Female bed bugs can lay from one to five eggs per day and ultimately 200 or 250 eggs in a lifetime.
- Eggs will hatch in five to 10 days’ time, and the emergent nymphs will immediately begin looking for a blood meal.
- It takes around four or five weeks for a bed bug to reach maturity, going through five molts along the way.
- Bed bugs will live around four to 10 months, but life spans may vary quite a bit based on conditions (and on your extermination efforts!)
The Life Cycle of a Bed Bug
Conclusion: an infestation can get rolling in less than a week, become unbearable in one to two months, and reach peak population levels in six months to a year, given the right conditions and plenty of blood.
What You Should Know
You may be wondering, “Do bed bugs go away if I just leave them alone a while?” Wishful thinking may have its merits, perhaps, but no, they normally won’t just go away on their own.
My Apartment Is Infested With Bed Bugs. Now What?
If your apartment definitely has a bed bug infestation, what can you do about it? You’ll need to learn how to kill bed bugs and how to keep them from coming back.
Here are Five Key Steps you can take to eradicate your blossoming bed bug population:
- Clear away all the clutter from your bedroom or other infested area. In fact, clean and organize your whole house like you were getting ready for white glove at college.
- Wash and dry all your clothes and linens that could possibly have gotten exposed to bed bugs or their eggs. Use the high-heat setting.
- Spray bed bug killer along the baseboards, into cracks and crevices, onto mattresses, box springs, upholstered furniture, and anywhere else it’s safe to spray it. Also apply diatomaceous earth under and around your bed, set up CO2 bed bug traps, and use rubbing alcohol to protect your exposed skin at night.
- Use a one-two punch bed bug fogger bomb approach. The first bombs will kill off adults mostly. Wait two weeks so the surviving eggs can hatch, and then bomb to wipe out the hatchlings before they mature and repopulate.
- You can repeat the four steps above several times, but if the problem persists, call in a professional who can safely heat your home to 118 degrees Fahrenheit to kill every bed bug.
Three Steps to be Bed-Bug-Free
Can They Come Back After Treatment?
Bed bugs can return the same way they got into your home to begin with, even after you totally eradicate them.
Thus, you need to think about how they may have gotten in. Stop bringing in garage sale or curbside furniture, routinely sprinkle diatomaceous earth along your door’s bottom if you live in an apartment complex, or change whatever else it takes to keep them out!
Learn how bed bugs spread into and throughout houses and how their population explodes. Take measures accordingly without delay to kill them and prevent a return. Knowing the facts about your bed bug infestation will help you end it!

How Fast Can Bed Bugs Spread?
Bed bugs have been in the news in recent years.After decades in which they seemed to have been almost eradicated, these pests are making a comeback. This is bad news for humans. According to the College of Agriculture at the University of Kentucky, bed bugs require a “blood meal” to survive, and they prefer the taste of human blood to that of other warm-blooded animals. These miniature vampires typically strike at night while people are sleeping, making a painless bite and sucking several drops of blood. Not known to carry infectious diseases, bed bugs nonetheless can cause allergic reactions to their saliva, and their bites leave itchy blotches similar to mosquito or flea bites. Hiding in inaccessible places, spreading out to all areas of a building and able to go months without feeding if necessary, they are difficult to find and control.
Once an infestation is underway, the property owner faces a tough eradication process that will require the services of a professional exterminator.This must be done sooner rather than later because they are hardy and they spread very quickly.
In the outdoors, bed bugs infest nests of birds, bats and other animals.These flightless insects, which measure 1/4 inch at maturity, enter a house, motel or apartment building by hiding in luggage, clothing or fabric. Once in place, the bugs set about reproducing, which they can do with impressive speed. Female bed bugs lay between one and five tiny eggs per day. Hatchlings are no bigger than a poppy seed.Once hatched, according to the School of Public Health at Harvard University, a baby bed bug or “nymph” requires only a single blood feast to molt and move into its next stage of development, which occurs five times before adulthood.
The nymphs reach maturity in a month or more, depending on conditions such as temperature (bed bugs like it warm) and the availability of blood. Assuming an average daily production of three viable eggs, simple math would indicate that at the end of one week, a single female would lay more than twenty eggs. Some weeks later, given a steady blood supply, these 20 bedbugs are adults. If half of them are females and each one lays twenty eggs in a week, this means a second generation of nymphs numbering approximately 200, all of which come from just one female bed bug. The production of three generations of bed bugs in a year is not uncommon.
Bed bugs can spread from one room or apartment to another through door frames, windows, or holes or cracks in the walls, ceilings and floors. They can contaminate wood furniture by laying eggs in cracks and recesses, and when that furniture is moved, these eggs (which can stay viable for years) may hatch in a new location. Weeks or months without blood do not harm these tough insects.As a result, if bed bugs are found, one should consult an exterminator immediately.
