An adult bed bug is about 1/5 inch long and 1/8 inch wide. Its reddish brown to mahogany-colored body is greatly flattened and oval shaped. After feeding, the bug's body enlarges considerably, becoming longer and much less flattened. Although the body is covered with tiny hairs, these hairs are so small that they are almost invisible to the naked eye, so the general body appearance is shiny. Bed bugs have piercing-sucking mouthparts that enable them to pierce the skin and suck blood from their hosts.
Bed bug infestations are primarily the result of two species of insects from genus Cimex: Cimex lectularius (the common bed bug) and Cimex hemipterus.[3] These insects feed exclusively on blood and may survive a year without eating.[3] Adult Cimex are light brown to reddish-brown, flat, oval, and have no hind wings. The front wings are vestigial and reduced to pad-like structures. Adults grow to 4–5 mm (0.16–0.20 in) long and 1.5–3 mm (0.059–0.118 in) wide.
When bed bugs are suspected, sleeping and resting places should be thoroughly inspected. Check all possible hiding places, mindful that bed bugs, especially the young nymphs and eggs, can fit into very tiny cracks and crevices. Don’t overlook places where pets rest, and where bats or birds have entered structures. In these instances, bat or bird bugs, not bed bugs, may be present. If bats or birds are a source of infestation, they should be excluded from the premises. Note that bats and most bird species are protected by law and should not be killed. Contact the Illinois Department of Natural Resources for guidelines on bat or bird exclusion and removal.
Our place is pretty cluttered so I was freaking out. Luckily we have hardwood floors and not carpet. We tried different things. It gets really hot here, so I loaded up any nearby sheets, pillows, comforters, clothes, etc into trash bags and tied them off so nothing could get out. I put those in the car so the sun could beat heat into them all day. Never thought I’d be so thankful for Texas summers… Still got bites. We bought a mattress cover. Still got bites. We thought, okay, maybe they’re coming from the wall socket from a neighbors or something. We couldn’t close it so we kept the bed away from furniture and walls and put sticky traps on the legs. Caught NO bed bugs but STILL GOT BITES. I was losing my mind.

One method of applying freezing temperatures to bed bugs entails the use of carbon dioxide (CO2) applied as “snow” with a portable application device, i.e., Cryonite™. When applied directly onto bed bugs, the frozen CO2 will kill them. However, this method is similar to using contact pesticides, that is, there is no residual activity. It can kill only as many bed bugs as the applicator can find. The advantage of using this type of freezing device is that bed bugs may be killed quickly and without the use of more hazardous pesticides. Again, this is not a stand-alone treatment, and it is recommended that it be used as a supplemental to the application of residual pesticides and/or other means of control.
Dust the wall voids. Bed bugs can often travel from room to room, especially in apartments, hotels and condo's. They travel along electrical wiring and plumbing lines. Specifically treat wall voids with a hand duster either by removing wall switch plate covers and/or drill access holes discreetly between studs. Cimexa Dust or Delta Dust are excellent choices for void applications. It kills populations in walls and voids and creates a repellent, hostile environment which reduces the likelihood of bed bugs traveling through voids to other areas. Use a small hand type duster to "puff" insecticidal dusts into these areas. A light coating is all that is needed. To much dust and the bed bugs will just crawl around it.
Avoiding bed bugs is most challenging in hotels, apartment buildings, and other places where there are many people, high turnover and ongoing opportunities for introduction of the pests. Periodic, preventive inspection by tenants, housekeeping/maintenance staff, or pest control firms is the best way to detect infestations in their initial stages when they are easiest to control. Visual inspections can be supplemented by using various monitoring devices to capture and reveal bed bugs that may have been overlooked by occupants.   
Bed bugs are obligatory bloodsuckers. They have mouth parts that saw through the skin, and inject saliva with anticoagulants and painkillers. Sensitivity of humans varies from extreme allergic reaction to no reaction at all (about 20%). The bite usually produces a swelling with no red spot, but when many bugs feed on a small area, reddish spots may appear after the swelling subsides.[15] Bedbugs prefer exposed skin, preferably the face, neck, and arms of a sleeping person.
Heat Treatment – this method kills bed bugs with heat. This could be implemented on clothes by putting them in a drier at a high temperature for 30 minutes. In a room, the use of heating devices could kill even the eggs and the nymphs of bed bugs at certain levels temperature at different durations of time. Ideally, to kill bed bugs in all stages, the temperature must be 115 degrees F or 46 degrees C.
Traps aren’t an effective way to wipe out a bed bug infestation, but they’re an excellent way to determine whether you have them. Set traps in areas where they may hide or travel, like near baseboard trim or under nightstands. If they aren’t living in your mattress or other parts of your bed, that means they need to travel up the legs of the bed frame to get to you, so place traps there as well.
Doctors often misdiagnose those afflicted because it is nearly impossible to tell, if you are experiencing an allergic reaction, what bit you. Often healthcare providers and individuals that have been bitten by a member of the Hemiptera order mistake bites for those of a mosquito. The only way to discern, with complete surety, what your bites are from, is to get a sample of what has bitten you.

People don't often consider bed bugs until they've left their mark. The appearance of flat, red welts in zigzag lines or small clusters is a key sign of bed bugs on humans. Bed bugs can also leave their bites in straight rows and, while they don't spread diseases to humans, their bites are quite irritating and scratching them can lead to bleeding and infection.


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.
Next, vacuum and steam along baseboards, window sills, and the edge of the carpet. When you’re done vacuuming, the bag or canister should be cleaned or discarded to limit exposure of bed bugs to other parts of the home. The steamer can also be used to treat sofas, chairs, furniture, and cabinets. When applying steam, remember to move the nozzle slowly (about one inch per second) to ensure that all bed bugs and eggs are killed.

Treat or isolate your bagged items. For washable items research shows that dry cleaning, washing in hot water for 30 minutes, or tumble drying for 30 minutes on high will kill all stages of bed bugs. Non-washables items that aren’t needed for a while can just be stored. It takes 2-5 months to kill bed bugs by isolating them in bags or heating bags by placing in direct sunlight is one of the most effective methods during the warm summer months.  
It often seems that bed bugs arise from nowhere. The bugs are efficient hitchhikers and are usually transported into dwellings on luggage, clothing, beds, furniture, and other items. This is a particular risk for hotels and apartments, where turnover of occupants is constant. Bed bugs are small and agile, escaping detection after crawling into suitcases, backpacks and belongings. Acquiring secondhand beds, couches and furniture is another way that the bugs are transported into buildings. Bed bugs also can be carried in on one’s clothing, shoes or wheelchair. Once bed bugs are introduced, they can crawl from room to room or floor to floor. They can also be transported throughout buildings on people and their belongings. 
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.
A few decades ago, bedbugs were somewhat of a novelty in developed countries. But since the early 2000s, infestations have become more common in places like the United States, Canada, the United Kingdom and Europe, according to the U.S. Centers for Disease Control and Prevention (CDC). A 2013 study in the journal Nature Scientific Reports suggested that bedbugs have evolved ways to resist insecticides.
If you arrive home and discover that you have brought some unwanted guests home with you, immediately notify the hotel of your discovery. Having a possible infestation in hotels and motels can be a public relations nightmare for the owners. Politely ask them to pay for any and all costs incurred to rid your clothing and home of a possible new infestation.

Bedbugs may enter your home undetected through luggage, clothing, used beds and couches, and other items. Their flattened bodies make it possible for them to fit into tiny spaces, about the width of a credit card. Bedbugs do not have nests like ants or bees, but tend to live in groups in hiding places. Their initial hiding places are typically in mattresses, box springs, bed frames, and headboards where they have easy access to people to bite in the night.
Bed bugs have been pestering humanity for thousands of years, but in the 1950s they finally met their match: the pesticide DDT. Then DDT was banned, but for most of the 40 years since, bed bugs have not been a major problem. Now, however, these blood-sucking vermin are back with a vengeance. That’s the bad news. The good news is that, unlike mosquitoes and ticks, bed bugs don’t spread disease, and there are practical steps you can take to prevent an infestation. And if you do get bed bugs, you can get rid of them yourself. We’ll show you what to look for, how do you get rid of bed bugs if you find them, and how to keep them out!

Bed bugs love fast food. They like to feed and then scurry back to their hiding places. They try to avoid crawling all over their food for fear of waking it/us. They usually bite the bare skin they find closest to the mattress. That’s why it’s common to see two or three bite marks in a line along the skin that was in contact with the mattress or pillow. When this happens it’s time to learn how to get rid of bug beds fast.


Bed bugs have five immature nymph life stages and a final sexually mature adult stage.[13] They shed their skins through ecdysis at each stage, discarding their outer exoskeleton.[14] Newly hatched nymphs are translucent, lighter in color, and become browner as they moult and reach maturity. Bed bugs may be mistaken for other insects, such as booklice, small cockroaches, or carpet beetles; however, when warm and active, their movements are more ant-like, and like most other true bugs, they emit a characteristic disagreeable odor when crushed.
Bed bug infestations have resurged since the 1980s[43] for reasons that are not clear, but contributing factors may be complacency, increased resistance, bans on pesticides, and increased international travel.[44] The U.S. National Pest Management Association reported a 71% increase in bed bug calls between 2000 and 2005.[45] The number of reported incidents in New York City alone rose from 500 in 2004 to 10,000 in 2009.[46] In 2013, Chicago was listed as the number 1 city in the United States with the worst bed bug infestation.[47] As a result, the Chicago City Council passed a bed bug control ordinance to limit their spread. Additionally, bed bugs are reaching places in which they never established before, such as southern South America.[48][49]
The mechanism of skin injury by arthropods depends on the structure of the mouthparts. These insects are categorized as vessel feeders if they insert the tip into a capillary or as pool feeders if they feed on the extravasated blood from damaged tissue. They often inject different pharmacologically active substances (eg, hyaluronidase, proteases, kinins), which may cause different skin reactions (eg, erythema, wheal, vesicle, hemorrhagic nodule). See the following images.
Should I worry about a tick bite? Ticks are parasites that feed on blood, and although their bites are harmless they can still transmit diseases, such as Lyme disease or Rocky Mountain spotted fever.
