Who Are the Bed Bugs, Where Do They Live and How Are They Dangerous for People

What Do Bed Bugs Look Like?

Bed bugs are long (up to ¼ inch long) wingless brown beetles with an oval flat torso and three pairs of short legs. As the New York State IPM Program put it, “they are also known as: Cimex lectularius, chinches de camas, chintzes or chinches, mahogany flats, red coats, crimson ramblers, wall lice, the bug that nobody knows, lentils on legs, animated blood drops”.

As the EPA specialists have accurately mentioned, a hungry bed bug looks like an apple seed. This hallmark is easy to bear in mind to recognize this parasite easily. The bed bugs only feed on blood, and its body swells considerably and takes deep red color (it can even become as dark as black). If you happen to come across a whole bunch of these insects, you’ll feel an unpleasant sweet odor which is exuded by the special glands at the bottom of a bed bug’s body.

These insects are extremely human-centered as humans are perceived as the center of the universe and an infinite source of food. Eating every 5-10 days and a temperature of 80° F are considered to be perfect conditions for the bed bugs’ life and breeding. Without food or if the temperature falls below 60° F, the bed bugs kind of hibernate and their metabolic processes are slowed down. They fall asleep till better days. According to the University of California Statewide IPM Program, they can remain in such state for up to 400 days. Alternatively, they are forced to attack warm-blooded animals, but this is a much rarer scenario.

How Do You Get Bed Bugs?

As you can imagine, insects do not appear out of nowhere, there is always a reason for their infestation. Here are some of the possible causes of bed bugs:

1. Tourism

At the moment, it is this huge-scale migration of people across the globe that generates more and more hotbeds of bed bug infestations. Here’s how it works: you travel, spend the night at a new place in and the bed bugs get into your things in your suitcase, and you're taking them home in it. That’s it. Then it will be like a time bomb. Having two little bugs will be enough to breed and make your sleep a living hell.

2. Neighbors

Since the bed bugs are great runners and can run up to 100 feet, it won’t be difficult for them to cover the distance between points A and B. We can’t guarantee that your place won’t become point B. If your neighbors are infested by the bed bugs, you are potentially endangered as well. Certain scientists believe that they can travel via a central heating duct.

3. Large crowds, be it dry cleaning or laundry facilities, airports, schools, libraries, offices, shops, public transport, theaters, etc.

Unfortunately, you can catch a bug in any of these places, so bear in mind some basic rules: check your clothing and carry-on luggage once you return home if there is the slightest suspicion of bed bug infestation (for example, if you saw any bugs crawling in the laundry room).

BY THE WAY: your kids can catch not only bed bugs at school, but also some head lice. Find out which actions should be taken in this case from our Guide on How to Kill Lice.

4. Buying Used Furniture

Yes, the bugs can move in with you along with the used closet or dresser you purchased. They can even arrive with new furniture, in case the bed bugs inhabit the factory where it was made or the furniture store.

Where Can Bed Bugs Settle In Your House?

After the bugs manage to get into your house, they settle somewhere inconspicuous, such as behind the wallpaper, outlets, carpets, paintings, cracks, moldings, baseboards, etc. Their favorite spots are still the bed (mattress, frame corners, as well as bed linen) and wooden furniture. You would be, however, gravely mistaken, if you believe that the bed bugs limit themselves to inhabiting a single room. As the Texas A&M AgriLife Extension Service specialists explain, “Typically, an infestation starts in one room and spreads slowly to other places where people sleep”. That’s why they recommend deciding on a single place to sleep at your house and stick to the choice. Otherwise, the bed bugs will follow you as they are used to live at a distance of up to 8 feet away from human beings.

How Dangerous Are Bed Bugs for Human? The Bed Bugs Symptoms  

We can barely call these insects lovely roommates. The first thought that comes to mind at the sight of these swarming creatures is disgust and aversion as no one wants to live in a room infested with bed bugs. Some hypersensitive people can even be stressed by the bed bugs’ presence, the quality and quantity of their sleep will deteriorate, and they can develop a "persecution mania" (the feeling that the bed bugs still live in the house even after you killed them).

How really dangerous are the bed bugs and do their bites carry any diseases? Fortunately, the scientists agree that at the moment no clear relationship between the bed bugs’ bites and occurrence of certain diseases has been identified. Dr. Stephen A. Kells and Jeff Hahn from the University of Minnesota confirm this: “Bed bugs are not known to transmit disease to people. They have been discovered to harbor 28 different human pathogens, but fortunately, the transmission of these diseases to people has not been demonstrated”.

However, should you be hypersensitive to the substances the bed bugs emit with their saliva when biting, you can find yourself having an allergy, and such complications as the nettle-rash and others. However, as the U.S. National Library of Medicine reports, these cases rarely occur. Still, we have to warn you of the symptoms that should alert you:

  • if the small bites turned into big red spots;
  • sudden fever;
  • increased blood pressure;
  • breathing difficulty;
  • fatigue and lightheadedness.

Pay attention to any potential symptoms that are not typical of your healthy state, provided that you are not sick at the moment, and the symptoms have appeared after the bed bugs’ bites. Consult a doctor once you experience any of them.

How to Tell If You Have Bed Bugs

Suppose, the bed bugs have already infested your house, what should be done? Do not panic and do not rush to look for insecticides right away. Follow the 7 steps outlined below and you will already be on the halfway to the victory over the bed bugs. But first, you need to be 100% sure that it is the bed bugs that are in front of you.

The 5 Obvious Signs of Bed Bugs

Clearly, it is much easier to identify adult bed bugs than to than to note the presence of larvae on a light-colored mattress. A larva’s body is much smaller than an adult’s one, it is transparent or whitish. Mission impossible is finding the bugs’ pearly eggs which are the size of a pinhead.

We have found out that your attention is the best bed bug detector. The scientists advise conducting a regular, careful inspection of all the “potentially hazardous” zones in your bedroom, especially the bed and the mattress. It is such check that will allow you to begin getting rid of the bed bugs in time and not the use of any other devices for identifying the insects.

Furthermore, no matter how good the bed bugs are at hiding, the following signs always give them away:

  • Feces in the habitat
  • If you see some black dots (which are actually digested blood) somewhere where it’s supposed to be clean, make your conclusions
  • Larvae skins
  • Larvae throw them when turning into adults.
  • Blood stains on the bed sheets
  • The actual bed bugs you’ve squashed in your sleep
  • Bite spots on the human body

In order to be full, the adult bed bugs won’t get enough of a single small bite. Usually, they leave tracks of 3-5 itchy bites located next to each other. Most often they attack hands, feet, and the neck. These insects almost always bite at night, just before dawn, but in the case of severe hunger they can pay you a visit whenever.

How to Check for Bed Bugs? Top-3 Bed Bug Traps

If you either still hesitate whether you’ve been bitten by a bed bug or some other insect or haven’t been able to find a bed bug nest at home, try using the bed bug traps. There are two types of such devices: plastic traps and sticky traps.

The former are the double plastic cup-holders to be placed under the bed legs which keep the bed bugs crawling off the bed inside one circle, and the bugs crawling into the bed are kept in another one. Thus, being a 2-in-1 piece, the gadget allows you to track the movement of bugs and catch them. Climbup Insect Interceptor Bed Bug Trap for ~$33 is the most popular trap of this type today. Buy on

ClimbUp Insect Interceptor Bed Bug Trap

Monitoring devices such as ClimbUp® are useful for confirming the presence of bed bugs when a visual inspection cannot. When installed under bed legs, they also provide a barrier between floor and bed which can potentially reduce bites, especially when beds are pulled slightly away walls and encased, as Michael F. Potter, Extension Entomologist, University of Kentucky confirms.

The latter is sticky cardboard traps that can be placed anywhere and be used to monitor a variety of insect pests, including bed bugs. The idea of their operation is the same: when an insect touches the adhesive tape, it sticks to it and dies. Certain traps even have food bait. The following 2 products are considered to be the best sellers among top 100 traps on

7 Mandatory Steps of the Bed Bugs Treatment

Here are the 7 first steps to be taken as preparation if you want to get rid of bed bugs completely. No one ever said it would be easy.

All scientists agree that getting rid of the bed bugs is hard work. “Management will require employing several nonchemical methods such as vacuuming, washing bedding at a high temperature, using steam or heat treatment, and sealing up hiding places. Insecticides may be required to eliminate serious infestations. The best approach is to combine chemical and nonchemical tactics with increased sanitation and habitat modification practices” (University of California Statewide IPM Program).

  1. Ultimate cleaning. Even if the first idea that comes to your mind when you see the bed bugs is to flee, get yourself together. You still have some cleaning to do.
  2. Inspect your bed and any other potential bed bug shelter. Vacuum clean the carpets and floors, as well as all corners and crevices to remove as many adult parasites and their larvae as possible. The vacuum cleaner will not help to get rid of the bed bugs’ eggs (as they are too sticky), so use sticky tape in case you notice the eggs.
  3. Wash all of your clothes and bed sheets at 120°F so that all the bed bugs, larvae, and eggs are killed. Try to steam clean those items you can’t wash.
  4. If possible, take all the furniture outside, into the sun, as the bed bugs do not like extreme heat. If you have substantial bed bug infestation at home, and so a lot of things are to be treated, or if you travel frequently, a thermal camera for treating infected objects (such as Dr Infrared Heater, 18 cubic feet portable bedbug heater quickly reaches 120-155F in minutes and effectively kills bed bugs  for ~$175) will be handy. Buy it on Dr Infrared Heater
  5. Although most often the bed bugs are found in the bedrooms, sometimes they happen to migrate to other rooms, in the bathroom, for instance, so make sure you check everything.
  6. Warn your neighbors; ask them if anyone has the same problem as it is easier to kill the bed bugs together than alone. Do not be ashamed of having the bed bugs as they can settle even in the most luxurious buildings. As the Center for Disease Control and Prevention specialists claim, “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”.
  7. Insulate the bed, as the main source of infection. Do not dispose of it, even though getting rid of the bed bug nest seems to be the easiest solution. Your bed can be treated. First, insulate the bedroom: take away tables, chairs and other furniture which is directly adjacent to the bed. If possible, move the bed away from the window sill and walls.

Some of these steps can help you to get rid of dust mites too. Read more in our article "How to get rid of dust mites?".

What Kills Bed Bugs For Sure? Bug Bombs, Mattress Protectors, Sprays and Dusts and Their Effectiveness

Let us warn you: getting rid of bed bugs is a hard and long job to do. But if you are consistent and practice the integrated approach of combining the timely cleaning with the use protective covers for the beds and insecticidal sprays or dusts, you are guaranteed to succeed.

Experts still debate the effectiveness of various bed bug control products and active ingredients, but they are unanimous that vacuuming, washing bedding at a high temperature (120° F), using steam or heat treatment give a 100% result, Therefore, do not neglect these simple and banal at a first glance ways of killing the bed bugs.

A Single Bug Bomb Can Kill All Bed Bugs Immediately: True or False?

So, it’s time for some serious actions now! Many people try to use bug bombs and foggers to kill the bed bugs, but the Department of Health & Mental Hygiene, NY specialists, warn us: “Foggers and bug bombs are not effective against them”. This is so because the sprayed droplets of the synthetic fog cannot penetrate hidden spots inhabited by the bed bugs. The University of Kentucky scientists agree with this. They insist that the home insect foggers (“Bug Bombs”) are useless against crawling insects. When applied in this manner, very little insecticide actually penetrates into cracks, voids, and other hidden locations where cockroaches, ants, silverfish, and most other household pests congregate and spend most of their time. The main point is also that the ingredients within “bug bombs” also tend to be repellent, causing insects to scatter and move deeper into wall voids and other hard-to-reach areas, which means they are hiding a bit further!

It’s pointless to rely on any repellents either as the bed bugs’ bloodthirstiness is stronger than the smell. That’s why protective cases and insecticidal sprays remain the most effective means of dealing with the bed bugs today.

How Do You Get Rid of Bed Bugs? – With the Bed Bug Mattress Encasement!

According to the entomologists, 70% of the bed bugs in the house settle in the mattress, box spring and bed frame during a typical infestation. That is one of the priority tasks is to treat the infected bed and mattress and to protect the new bed by using protective encasements. Modern encasements are made of firm materials (polyurethane, polyester, etc.) the pores of which are smaller than the bed bugs so that you could lock up all existing bed bugs and their larvae inside and prevent new bugs from getting into the mattress from the outside.

Remember! In order to completely get rid of the bed bugs, the encasement should cover the mattress for a year as it is this period of time that is required for the captivated bed bugs to starve. If you happen to take the encasement off and then put it back on, you might as well start everything all over again.

Here is the #1 Bestseller in the Mattress Encasements category on LINENSPA Zippered Encasement Waterproof, Dust Mite Proof, And Bed Bug Proof Breathable Mattress Protector.

How to Get Rid of Bed Bugs: Dusts and Powders

Here is what Michael F. Potter, Extension Entomologist, University of Kentucky recommends to those who cannot afford a professional exterminator:

Bed bug eradication is challenging, and it’s prudent to hire a professional when resources allow. However treatment can be expensive, often costing hundreds or thousands of dollars. Those who cannot afford this often must cope with the problem themselves. A useful step that anyone can take to combat bed bugs is to install bed encasements. Covering the mattress and box spring can help eliminate a substantial portion of the bed bug population.

Bugs that are spotted can be removed with a vacuum, or killed with over-the-counter insecticides labeled for such use. Most bed bug sprays intended for householders have little remaining effect after the spray has dried. Therefore, it’s important to initially contact as many of the insects as possible with the spray droplets. Some insecticides applied as powders or dust (e.g., diatomaceous earth) will kill bed bugs although boric acid powder will not.

Let’s start with Diatomaceous Earth, which is recommended by the scientists, as the bed bugs have not yet had time to get used to it and become resistant, which is, incidentally, confirmed by the EPA.

Diatomaceous earth kills bed bugs

Diatomaceous Earth is the remains of diatom algae composed of silicon dioxide. It is this compound that has an abrasive effect on many insects, including the bed bugs. It dries their armor – their exoskeleton, and the insects die. That is why the bugs do not need to eat the powder to be poisoned and die, it will be just enough for them to touch it. In spite of such killing effect of its use, Diatomaceous Earth is organic and completely safe for people and pets. It only costs ~$21. Buy on

How should you use Diatomaceous Earth? You’ll need for that a special kind of sprayer duster, like Pest Pistol Mini Duster for ~$10.90. You’ll have to treat all of the bed bug infestation hotbeds, be it cracks and crevices in the floor, walls, furniture, bed frame and the space around it, etc. The scientists recommend refraining from using other pesticides along with the Diatomaceous Earth (but make sure you do apply other bed bug control ways) and being patient, as the bed bug killing can take up to 2 weeks.

The only downside of using Diatomaceous Earth is the dust which will cover your entire room. If you want to use a cleaner product, pay attention to several bed bugs sprays which are trusted by the insecticide consumers and which you can use for getting rid of bed bugs on your own.

Getting Rid Of Bed Bugs with Sprays

It is available for ~$20.99 for 1 gallon. Buy it on

bed bug insecticidesHowever, bear in mind that certain bed bugs species have adapted to the pyrethroid insecticides. That’s why you should make sure the manufacturer states whether the product is effective against pyrethroid insecticide-resistant bed bugs.

If you do not want to use insecticides, there are a lot of natural-based bed bug sprays based on oils available on the market. Although many pest control experts doubt the high effectiveness of the oil-based bug killers as they are really very tenacious of life insects and learned to adapt to any kind of poison with time, give it a try if it is important to you to use all natural products. The manufacturers promise that their sprays will kill the bugs, larvae, and eggs by direct contact of the liquid with the parasites. The sprays are to be applied on all open and hidden spots where the bed bugs can settle. In fact, we’re speaking about everywhere from the floor to ceiling, including the hideaway spots, such as place behind the pictures, wallpapers, cracks in floors, walls, etc.

Among the best selling natural sprays in the Pest Control Sprayers category on, you can find the Bug Killer by EcoRaider for ~$18.99. According to the manufacturer, this is “The only natural product kills bed bugs with 100% efficacy according to Entomological Society of America's published study “. It is promised to kill the bed bugs at any life stage as well as to eliminate the resistant bed bugs.

natural bed bug killer sprayNB! Regardless of which spray you’ve picked, don’t apply it spot-on as the bed- bugs will get used to it and will simply flee to other places. You are supposed to treat the entire premises with it.

Also, while the room treatment does not cause any concerns, you have to be careful with the treatment of the bed and linen. Even the natural sprays contain sls, which is a synthetic sodium lauryl compound which is commonly used in household chemicals production and other products. The United States Department of Agriculture specialists has proven that the prolonged contact of the sls with skin may result in dermatitis. Therefore, if you have sensitive skin, wait for a while before falling asleep on the treated bed sheets.
