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.
Skin reactions from bed bug bites vary from person to person. Bites may go unnoticed or may be mistaken for flea or mosquito bites or other skin conditions. The most common skin reaction to bed bug bites are itchy red bite marks that appear clustered or in a straight line, often along the edge of clothing or where sheets were pulled up to a person's skin. Small swollen red bumps are also common. In rare cases, people may develop large, often itchy, red welts. A single bed bug bite is similar to a flea bite, except that a red area does not occur in the center. Flea bites tend to be found around the ankles while bed bugs tend to bite any exposed area of the body while a person is sleeping, such as the face, neck, arms, hands, or legs.
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. 
Turns out, C. lectularius is also forming a resistance to other insecticides, according to a study published online April 10, 2017, in the Journal of Economic Entomology. The researchers, from Purdue University, found that three out of 10 bedbug populations collected in the field showed much less susceptibility to chlorfenapyr, and five of the 10 populations showed reduced susceptibility to bifenthrin, according to a post on Entomology Today. The scientists defined "reduced susceptibility" as a population in which more than 25 percent of the begbugs survived after seven days of exposure to the particular insecticide.
Bedbugs are parasitic arthropods from the family Cimicidae. They are typically less than 1 cm in length and reddish brown in color. Bedbugs can be found in furniture, floorboards, peeling paint, or other small spaces, most commonly in areas of clutter. These insects come out at night in search of prey upon which to feed, with peak feeding times just before dawn. Bedbugs are typically attracted to body heat, carbon dioxide, vibration, sweat, and odor. The image of a Cimex lectularius is shown courtesy of the US Centers for Disease Control and Prevention (CDC).
These nocturnal creatures can hide in beds, floors, furniture, wood, and paper trash during the day. We humans usually become their dinner during the night, with peak biting activity just before dawn.They can obtain their meal in as little as three minutes, after which they are engorged and drop off the host, then crawl into a hiding place to digest their meal. Bedbugs can live for 10 months, and can go weeks without feeding.
If you live in an apartment or condominium, it’s best to alert the property manager.  A coordinated bed bug control effort using a pest control company is generally needed in such situations. Bed bugs readily move from apartment to apartment, with many people unaware that they have a problem. If one apartment is infested, adjoining units (left side, right side, above and below) should be assumed to be infested unless shown otherwise through inspection or monitoring.  Simply asking tenants whether they have bed bugs is not enough.  In one recent study only half of apartment residents whose homes were determined to have bed, bugs knew (or admitted) they had a bed bug problem.
Bed bugs are attracted to their hosts primarily by carbon dioxide, secondarily by warmth, and also by certain chemicals.[4][16][17][18] Cimex lectularius only feeds every five to seven days, which suggests that it does not spend the majority of its life searching for a host. When a bed bug is starved, it leaves its shelter and searches for a host. It returns to its shelter after successful feeding or if it encounters exposure to light.[19] Cimex lectularius aggregate under all life stages and mating conditions. Bed bugs may choose to aggregate because of predation, resistance to desiccation, and more opportunities to find a mate. Airborne pheromones are responsible for aggregations.[20]

When professionals need to treat an infestation, they don’t reach for rubbing alcohol or cedar oil or a blow dryer. They use a proven treatment process that involves a combination of proven products to get the job done. It’s not about whether or not a certain item can kill bed bugs, it’s about whether that item is the ideal part of a treatment that will actually get rid of an infestation. After all, your shoe would have a 100% kill rate on any bed bugs you smack with it – that doesn’t mean you can expect to be bed bug free after a diligent afternoon of shoe-wielding.
My husband works for a garbage company (this is how we think the invasion started) and at the moment they are localized to our bedroom and our bathroom. However, the first place we found them was in our headboard & footboard. It is wood with an intricate carving. We checked the mattress and box spring and didn’t find a thing. But they LOVE that wood.
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.  
Research has shown that some bed bugs are resistant to the pyrethroid pesticides that have been most commonly used in recent years by pest management professionals. Likewise, pyrethroids such as deltamethrin and permethrin have been among the active ingredients most commonly available in pesticides at retail stores. The ongoing use of pyrethroids has undoubtedly contributed to the resistance we see today in some bed bug populations.

Prior to the widespread use of synthetic insecticides, this small, brown blood-sucking bug was perhaps the most unwanted pest in America. The insidious bed bug was loathed even more than the cockroach. Although the bug’s impact was greatly reduced by insecticides during the 1940s and 1950s, it remained an occasional invader of homes, hotels and shelters. Pest management professionals now agree that bed bugs have become the most difficult pest to control.
A flashlight:  Bed bugs hide in dark areas and in cracks and crevices.  Bed bugs are a dark red to brown color, but they can be light brown if they haven’t been feeding. This makes it very hard to see them. When hunting for bed bugs hold your flashlight parallel to the surface being inspected, this will cause eggs and small bed bugs to cast a shadow, making them easier to find.
As for traps, these capture methods may not be full-proof for all bedbug species. Researchers have found that while both the common and tropical bedbug species have hairy feet, C. hemipterushas denser foot hairs, making this tropical insect an expert climber on slick surfaces. In the study, detailed on March 15, 2017, in the Journal of Economic Entomology, the researchers found that adult tropical bedbugs were much better at escaping traditional pitfall traps, which held onto most of the common bedbugs in the study.
With practice and a flashlight, nonprofessionals can become proficient in finding and destroying bed bugs. The process is made easier by reducing clutter, especially in bedrooms and sleeping areas. Bugs that are spotted can be removed with a vacuum (see previous discussion), 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. Insecticide labels should be read carefully as some bed bug products should not be used on mattresses and seating areas. Some insecticides applied as powders or dusts (e.g., diatomaceous earth) will kill bed bugs although boric acid powder will not. However powders can be messy and difficult to apply, especially by nonprofessionals. Total release foggers (otherwise known as ‘bug bombs’) are ineffective against bed bugs and potentially dangerous when used incorrectly (see University of Kentucky entomology fact sheet Limitations of Home Insect Foggers).
Bed bugs will also succumb to cold temperatures below 32°F, but the freezing temperatures must be maintained for a longer period (e.g., one to two weeks). Consequently, heating tends to be a better option throughout much of the country. Efforts to rid entire dwellings of bed bugs by raising or lowering the thermostat will be unsuccessful, although pest control firms are able to achieve lethal temperatures with supplemental heaters (see the subsequent section entitled "Heat Treatments" for more details). 
The Diatomaceous Earth seems to kill them and centipedes. Didn’t even know I had those til I put powder down to prevent bed bugs and found one curled up dead. It dries them out and kills them. Works great! I’ve heard boric acid doesn’t work on bed bugs but I do know it works wonders on killing roaches. My sister had them in an apartment & boric acid wiped them out!

While most of the bed bugs were wiped out by the chemicals, three groups continued to thrive after being treated with chlorfenapyr, and five groups were still kicking after being treated with bifenthrin. That means that while some bed bugs will respond to these chemicals, others won't—and it's likely that more and more bugs will become resistant over time.


Bed bugs are not a new pest problem. These bugs have been around for centuries. They know how to avoid our attempts to kill them. If these bugs have gotten into your home or business, don't attempt to get rid of them on your own. Call a pest control company immediately. A certified and educated pest professional knows how to administer bed bug control products in a way that adheres to all government regulations and the best practices set forth by experts in the industry. A pest technician will also offer advice on how you may have acquired the bugs and how to prevent future infestations from occurring.
Some patients develop blisters filled with blood or bloody fluid, especially on the arms and legs. These blood blisters are extremely rare and can burst, causing bleeding or oozing of the bloody fluid. Healthcare providers are not sure if the cause of these blisters is related to the bug or the human but have found groups of patients that were all bitten by bugs on the same train exhibiting this sign.
Insecticides might also have their work cut out for them: Entomologists have known that the common bedbug has built up resistance to some typical insecticides such as those containing certain pyrethroid chemicals like deltamethrin, according to Entomology Today. Deltamethrin apparently paralyzes an insect's nervous system, according to Cornell University.
Reactions to bed bug bites vary among individuals. Many persons show no signs of bites. Others don’t realize they’ve been bitten until redness and swelling appear around the bite, sometimes with intense itching. Some exhibit inflamed swollen spots that may occur in linear series or have a rash-like appearance. Such bite marks, when they appear, may not show for several days after the person is bitten.
