How Long Before Bed Bugs Come Out
How to Find Bed Bugs
If you have a bed bug infestation, it is best to find it early, before the infestation becomes established or spreads. Treating a minor infestation, while an inconvenience, is far less costly and easier than treating the same infestation after it becomes more widespread.
However, low-level infestations are also much more challenging to find and correctly identify. Other insects, such as carpet beetles, can be easily mistaken for bed bugs. If you misidentify a bed bug infestation, it gives the bugs more time to spread to other areas of the house or hitchhike a ride to someone else’s house to start a new infestation. Learn about identifying bed bugs.
Bites on the skin are a poor indicator of a bed bug infestation. Bed bug bites can look like bites from other insects (such as mosquitoes or chiggers), rashes (such as eczema or fungal infections), or even hives. Some people do not react to bed bug bites at all.
Looking for Signs of Bed Bugs
A more accurate way to identify a possible infestation is to look for physical signs of bed bugs. When cleaning, changing bedding, or staying away from home, look for:
- Rusty or reddish stains on bed sheets or mattresses caused by bed bugs being crushed.
- Dark spots (about this size: •), which are bed bug excrement and may bleed on the fabric like a marker would.
- Eggs and eggshells, which are tiny (about 1mm) and pale yellow skins that nymphs shed as they grow larger.
- Live bed bugs.
Where Bed Bugs Hide
When not feeding, bed bugs hide in a variety of places. Around the bed, they can be found near the piping, seams and tags of the mattress and box spring, and in cracks on the bed frame and headboard.
If the room is heavily infested, you may find bed bugs:
- In the seams of chairs and couches, between cushions, in the folds of curtains.
- In drawer joints.
- In electrical receptacles and appliances.
- Under loose wall paper and wall hangings.
- At the junction where the wall and the ceiling meet.
- Even in the head of a screw.
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 Bugs: Everything You Need to Know
Belonging to the orderhemipteraor true bugs, bed bugs are household vampires that feast on blood. They undergo a slow metamorphosis through a 5-stage life cycle that begins as an egg hatching into a nymph to end as a mature breeding adult with a nasty bite.
In this guide, I’ll walk you through what a bed bug is, how to spot them, and their life cycle.
A Quick View of Characteristics
The common bed bugs are interested in humans and don’t go for animals with fur. They can cover a lot of distance and travel about in personal belongings such as purses, luggage or gym bags. Bed bugs hate heat, so they won’t travel directly on your body, so protecting your belongings is the best way to prevent infestation.
Spotting Adult Bed Bugs
Have you seen apple seeds? Adult bed bugs look quite similar. Depending on their age, they are between 4.5mm and 7mm long and go from white when first hatched to a deep mahogany brown. A closer inspection reveals six legs, an oval-shaped abdomen and two short antennae.
Being an insect their anatomy is divided into three parts, head, thorax and abdomen.
- Head: Bed bugs have a tiny head and an eye on each side for 180 degree vision. For a nose they have a sharp ‘beak’, the clypeus, used to pierce skin. You may not notice it’s long proboscis since bed bugs keep it tucked under their bodies unless they are feeding. There are also two antennae.
Thorax: The midsection of a bed bug is called the thorax. Compared to other insect thoaxes, it’s quite tiny. Nearby there are rudimentary ‘wing casings’. There are no wings.
Unlike many other similar-looking bugs, their bodies look quite segmented when you view them from above, and that separates them from carpet beetles and spider beetles. Their oval-shaped bodies also help identify them. They are wingless, which means they just cannot fly. Many people say that bed bugs can fly because they have wing pads. That’s not true because they do have the vestiges of wings but they are not developed enough to help them fly.
So, how do they move? Well, they crawl, and more interestingly, they are capable of covering up to 4 feet in a minute. It may not seem far, but it’s usually enough for them to find a hideout when you try to kill them.
The Bed Bug Life Cycle
In their lifetime, bed bugs go through three stages including molting twice as an adult.
- Egg: Eggs are tiny and pearl white in color. They are laid in dark spots around your home. They take about 6 to 9 days to hatch.
Nymph: During the second stage, nymphs or juvenile bed bugs hatch and are around 1.4mm long although some can be up to 4mm. Each nymph passes through five stages, known as instars to become an adult, and it takes about 5-8 days to complete each instar. Nymphs look like adults but they cannot breed.
When you talk about getting rid of a bed bug infestation, it’s important to try methods that clear the adults and eggs, as well as all the nymphs.
Being white, nymphs are harder to spot but they only stay white until they take their first feed. Nymphs have a red lump in their abdomen where they store their blood meal as they slowly digest it. Once it’s completely digested they molt and shed their exoskeleton so they can grow larger.
As they continue to digest and grow they turn brown. The color change shows they have absorbed the nutrients in the blood. In total, the nymph passes through five sub-stages or instars and with the completion of each, they get browner. Once an adult, they don’t change color again.
Nymphs molt during instars and will molt five times altogether before they are mature adults. Between each molt, they need a blood meal to survive. Even though nymphs are small and too young to breed, they are still looking for a meal from the instant they hatch.
Fact: Did you know that after feeding, those nymphs could grow six times their body weight?
Can You See Bed Bugs With The Naked Eye?
Of course, which is helpful if you’re on a mission to confirm you have a bedbug infestation. The adult bedbugs are the largest and darkest especially when they have recently fed. They also move much more slowly after they’ve just eaten.
Nymphs are tiny but still visible despite being no larger than a pinhead although you might have trouble finding them without a torch.
Bed bugs are nocturnal so active at night, but that doesn’t mean they won’t come out during the daytime to feed if there’s an opportunity. Even so, they prefer to hide in safe crevices and cracks during the day. This makes finding their hideouts more of an issue rather than being able to see them with the naked eye.
Differences Between Males and Females
It’s a subtle difference but still noticeable. To determine a bed bug’s gender, you need a close look at their abdomen. Ones that look slightly rounder are female bed bugs. Males are slimmer and more elongated, especially when unfed.
A more obvious difference is at the tip of the abdomen. A closer look will show that females have rounder bodies whereas males have a more pointed tip, which is considered their sex organ.
Fact: Did you know bed bugs bite a lot but you don’t feel it because they inject an anesthetic and anticoagulant while sucking blood but that may leave you with reddened bumps?
The Bed Bug Reproduction Cycle
Dealing with a bedbug infestation is difficult not only because these pests have become resistant to common pesticides but because they reproduce very quickly. If it was possible to find a way to stop them reproducing, we’d be able to get rid of them once and for all.
Once a nymph passes through five stages and turns into an adult, it’s ready to breed. Bed bugs use a process called traumatic insemination. A male bed bug has to break through the shell of a female to inject sperm directly into its body. After traveling through the female’s body, the sperm eventually reaches eggs to fertilize them.
Something that makes this whole process bad news for households is that once fertilized, the female is capable of lying at least one egg a day, and she can mate again to keep topping up the number of eggs she is carrying. This process continues for 6-8 weeks, which means plenty of eggs to grow into new bed bugs.
Each female bed bug lays up to 200-250 eggs although some studies have recorded females lying more than 500. It all comes down to the right conditions. Females are likely to lay more eggs in warmer temperatures and in places where breeding and feeding conditions are most suitable.
Compared tocimex lectularius, the common bed bug in the U.S., lays many more eggs than their tropical cousins.A tropical bed bug lays no more than 50 eggs in her entire lifetime.
Fact: Did you know female bed bugs often migrate away from their harborages after the undergo traumatic insemination?
Can Bed Bugs Survive Without a Blood Meal?
One reason why we have failed to get rid of bedbugs for good is that they are very resilient and more than capable of managing without meal. However, once they have fed, it takes them a long time to digest the blood. Left unfed, they can last months without blood meal.
Bed bugs can live longer without food when they are in cooler environments. In fact, experts believe that bed bugs can live up to a year without feeding at 55F or less. However, they may find it a bit harder to survive without food in temperature-controlled buildings but they can still survive for 6 months.
This means that even leaving your home for a few months is not always going to work. These little blood-suckers won’t starve to death waiting for you to return.
Bed bugs are notorious household pests, and as they reproduce quickly, with each female laying over 200 eggs, it doesn’t take long before you have a heavy infestation at hand. Leaving it unattended would result in serious issues, including itching and allergic reaction.
Identifying those bugs, however, will help take quick actions and may make it possible to eradicate an infestation before the problem spirals out of control.
How Long Does It Take For A Bed Bug Infestation To Develop?
ByChris Williamson February 6, 2012.
I was recently sent to a job to inspect for Bed Bugs. Previous tenants had been treated for bed bugs and have moved out. Management wanted to know two things: How long has the unit been infested, and were there any live beg bugs. Inspection for bed bugs can be difficult as most units are full of furniture and belongings, this unit was vacant and empty. With full access to all areas of the unit the extent of the infestation was more clearly defined.
Bed bugs, the scourge of the rental industry, are small insects that feed exclusively on human blood. Long lived and easily spread, bed bugs secretive lifestyle makes detection difficult. Relatively few bed bugs start an infestation. In fact, if a male bed bug is the only hitchhiker, no infestation will develop. Only female bed bugs are able to lay eggs. A mated female can lay around 3 eggs a day if feeding is available, laying more than 300 eggs in her lifetime. Small white eggs are cemented to discrete surfaces, near a host, and hatch in about 10 days. Nymphs resemble adults but are much smaller. In order to grow, or molt, nymphs must acquire a blood meal. Depending on the temperature, it takes nymphs about 100 days for the five molts to occur before mating can take place. Roughly 1.5-2 months are required for a complete cycle from egg to mated adult bed bug. Adult bed bugs live about 10 months, although without a host, bed bugs may live over a year.
Bed bug infestations develop slowly. At first very few insects are present, feeding intermittently on the host and may not be noticed. Bites are sometimes overlooked or blamed on some other pest species like spiders. Secretive adults may not be noticed as they feed on sleeping hosts. Over time though, evidence builds up. Bed bugs are gregarious, and can be found living side by side in harborage sites. Great numbers of nymphs and adults can be found together. As these sites become more active, females will migrate to areas of less activity to lay eggs. Male bed bugs want to mate constantly with females, driving them away. This behavior is believed to be what makes bed bugs “spread out” into new areas. Large populations also use up more and more of the hiding spaces near the host, and are forced to seek shelter farther from the feeding site. All the while the bed bugs are pooping. Bed bug feces is little more that partially digested human blood. Fecal spots form as the bed bugs move about and accumulate in and around the harborage sites. Fecal spots are usually clustered, and may have a small “smear” at one side, indicating the direction of the bed bug’s travel. In heavy infestations there may even be a discernable, almost sweet odor, due to large amounts of feces and aggregation secretions. As bed bugs molt during the growth process, the smaller old skin is shed and a new larger skin forms. These skins are also left where they fall and may accumulate over time. In heavy infestations, there may be considerable numbers of these cast skins.
Now, back in the unit to be inspected, I am looking for evidence. I begin with a cursory look around. With a bright flashlight, pliers, and a screwdriver in hand I start with the ceiling edges and walls. As harborage sites become full, bed bugs will end up in corners and on walls. Right away I begin to notice some fecal spots on door frames and at lower closet edges. No activity behind outlet covers, or under carpet in the 2 bedrooms, 12-25 dead bed bugs noted on the bed room floors, some fecal spots on lower closet door and door frames, no live activity. Bases of all 3 hall closet door frames also had fecal spots, dead bed bugs, no live activity. As I began to examine the living room, there seemed to be more and more dead bed bugs, and fecal spotting, increasing as I got over to the baseboard radiator. Fecal spotting all over the metal housing and adjacent molding told me I was getting warm. When I dismantled the housing and pulled the carpet out from under it I hit pay dirt. 1000’s of cast skins, large pockets of blood stained carpet(major harborage site), and hundreds of dead bed bugs were deposited under the carpet and heating unit. There must have been a couch or bed right there. As the infestation grew, the bed bugs spread out along the floor edge and eventually found the bed rooms, where there was much less fecal spotting etc. In my opinion, the focal point of the infestation was the living room. As far as a time table is concerned, based on the life cycle, amount of fecal spotting, and the number of cast skins noted, the infestation was more than a year old, maybe older. 2 live bed bugs were found, although upside down, on the kitchen floor. This indicates that the treatment was working, and that bed bug control is almost complete. My recommendation was to re-treat the unit prior to new tenants moving in to ensure that the infestation is gone completely.

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!
