The size of bed bug bites varies with a number of different factors. Bed bugs inject an anti-coagulant along with their saliva when they pierce the skin to take a blood meal. This anti-coagulant is mostly responsible for how a person reacts to the bite and determines the size of the bug’s bite. Since people will have various sensitivities to the bed bug’s bite, the size of the bite will vary, as well. Another factor that influences the size of a bed bug reaction is the number of times a person is bitten. Bite reactions of people bitten many times are also variable, and their response may be either more or less intense as the number of bites increases.
Until fairly recently, most people (and even pest control professionals) had never seen a bed bug. Bed bug infestations actually used to be very common in the United States before World War II. But with improvements in hygiene, and especially the widespread use of DDT during the 1940s and ‘50s, the bed bugs all but vanished. The pests persisted, however, in some areas of the world including parts of Africa, Asia, and Eastern Europe. Over roughly the past decade, bed bugs have made a dramatic comeback in the U.S.― they’re appearing increasingly in homes, apartments, hotels, health care facilities, dormitories, shelters, schools and public transportation. Other places where bed bugs sometimes occur include movie theaters, laundries, rental furniture, and office buildings. Immigration and international travel have contributed to the resurgence of bed bugs in the U.S. Changes in modern pest control practice, less effective insecticides ― and a decrease in societal vigilance ― are other factors suspected for the recurrence. 
Insect and spider bites and how to deal with them Insect and spider bites can occur almost unnoticed, or they can be painful. Either way, home treatment is usually enough for most symptoms. However, some bites can spread serious disease, such as Lyme disease and malaria. Find out how to protect against bites and what to do if someone has a severe reaction to a bite. Read now

Bedbugs normally feed at night, usually approximately 1 hour before dawn. However, if the conditions are favorable, they also feed during the day. Feeding takes 3-12 minutes. In proper conditions, adult bedbugs can survive without a meal for 1 year or longer. Each female lays approximately 300 eggs in her lifetime. The eggs hatch in 10 days. The nymph stage lasts 6 weeks, undergoing 5 molts.
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.
Both of these types of Hemiptera are sensitive to extreme temperatures. It may be necessary to rid the infestation by exposing the area to extreme heat or cold; they are most comfortable in temperatures around eighty degrees Fahrenheit. Raising the temperature to ninety-seven to ninety-nine degrees may kill off a significant portion of the population.

I was at a motel for a week, and had no problems with bed bugs. I then left to go to a shelter, because I had no more money to pay for a motel. The second day I went job searching all day, and started itching really bad on the back of my neck. At first I thought it was from the heat, and from me sweating. I then looked at my neck and noticed red swelling bites on my neck, and I scratched it to make the itch go away. I then noticed as the day progressed that it was spreading fast up the back of my neck. Now I’m getting worried, what is this, and why is it itching and spreading so fat. I asked the shelter workers what they thought it was and they said, I don’t know, but you can take anti-itching cream. I took the cream and put it on my neck, the itching went away, but the bites still were there. The next day I wake up and I have another bite on my upper right arm, and a bite on my right thumb. That night I talked to a resident staying there, and she said you have bed bug bites. I was so disgusted and scared. She then told me that three other people had the same problem I did, with the red bumps on their neck too, and they had left because of it. I want your advice on if I should persue legal action. Thank YoU
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.

Bed bugs have a fast and large reproduction nature. On an average, they can reproduce within 200 to 250 eggs at one time, and hatch during an interval between 6 to 10 days. Bed bugs largely live between 4 months to 6 months, and a 1-time treatment is not sufficient to cover the Bed Bug life stages. A 3 times treatment integrated with steam treatment and follow ups across 1.5 to 2 months is usually recommended. Read more here on 6 Questions to Get the Best Treatment for Bed Bugs.
Wash the bites with soap and water. Wash the area with mild soap and water; use a bar of soap and enough water to wet surface of your hands. Work the soap in your hands into thick, soapy lather. Rub the lather over the affected area liberally. Repeat until the entire area is covered. Leave on and do not rinse. Allow the soap lather to dry over the bitten areas. You should experience immediate relief from itching.[5]
you probably ALREADY HAVE THEM..you cant let people that you know have an infestation of blood sucking parasites in your HOUSE..im sure you already have them but a hot dryer does kill them yes but thats not going to protect you these are very easily spread they fall off their bodies or hair right into your house & if you have children with bedbugs in your home you most likely already have them..sometimes people have no idea they even have them the bites dont affect some people..other people after about 3 week get an allergy & thats why the bites swell like hives..they became allergic & that can be a dangerous allergic reaction
After treating a mattress or box spring for bed bugs, we recommend encasing each in a bed bug proof cover. This will prevent re-infestation and will make future inspections and treatments easier. Be sure any product that has been sprayed or applied to your mattress is dry before you cover the mattress with a bed bug proof cover. You can make the bed with your freshly laundered linens over a bed bug proof mattress cover.
The creatures don't have wings and they can't fly or jump. But their narrow body shape and ability to live for months without food make them ready stowaways and squatters. Bedbugs can easily hide in the seams and folds of luggage, bags and clothes. They also take shelter behind wallpaper and inside bedding, box springs and furniture. The ones that feed on people can crawl more than 100 feet (30 meters) in a night, but typically creep to within 8 feet (2.4 m) of the spot its human hosts sleep, according to the CDC.
Apply residual Bed Bug Insecticide Spray. After every crack, crevice, switch plate, electrical switch, baseboard, box springs, mattress, etc, has been treated and everything is put back, it is time for the residual treatment. Using a hand held sprayer such as the Chapin Sure Spray apply Optimate, Cy-Kick, Suspend SC or Demand along the baseboards in the bedroom and closet, under and around the bed, behind the headboard, inside bed stands etc.
A definitive diagnosis of health effects due to bed bugs requires a search for and finding of the insect in the sleeping environment as symptoms are not sufficiently specific.[5] Bed bugs classically form a line of bites colloquially referred to as "breakfast, lunch, and dinner" and rarely feed in the armpit or behind the knee which may help differentiate it from other biting insects.[4] If the number in a house is large a pungent sweet odor may be described.[4] There are specially trained dogs that can detect this smell.[2]
Desiccant dusts.  Two low toxicity dusts with good effectiveness include silica aerogel and diatomaceous earth (DE).  Both of these dusts are low risk to humans, and work by desiccating, or drying out, bed bugs that come in contact with it. Silica aerogel is, in some studies, superior for this purpose.  It is sold under various trade names including Tri-Die™ and CimeXa™.  Diatomaceous earth can also be effective.  Look for DE for insect control–it is not the same product as diatomaceous earth used in swimming pool filters, which is dangerous to breath. Some pest control companies now use desiccant dusts extensively in bed bug control. These relatively inexpensive dust can be purchased online or in garden centers or hardware stores. Look for products labeled for indoor use and lightly dust all accessible crack, crevices and voids.  A paint brush is useful for applying these dusts to seams and crevices in sofas and mattresses, along baseboards and inside drawers and dresssers.
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.
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.
Heat treatments of this type are advantageous because they present no pesticide hazard. However, they also provide no residual activity. That is, they do not prevent a structure from being re-infested after it is heat treated. For this reason, residual pesticides are often applied in conjunction with heat treatments. Such applications may not prevent re-infestation, but help control any bed bugs not killed by the heat. A certain percentage of heat treatments, perhaps 10 to 20 percent, fail to kill all the bed bugs present. Often this is due to residents failing to adequately prepare the premises for heating.
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 are a little trickier.  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 (the warmer the temperature, the shorter the survival time for starving bed bugs). Heating bags by placing in direct sunlight is one of the most effective methods during the warm summer months.  Seven pounds of items placed in clear bags in direct sunlight on a 95 degree day will get hot enough to kill all bed bug life stages in one afternoon.  Also, placing bagged items in a chest freezer (0 degrees F) for 8-10 hours is lethal for bed bugs and their eggs. Some toys may be disinfested by cleaning with hot soapy water and/or rubbing alcohol.
The first sign of a bed bug problem is obvious: the bed. After bed bugs feed on humans, they'll leave behind blood stains resembling small rust spots. These will usually be found near the corners and edges of the bed. Bed bugs also shed their skin, or molt, several times as they mature, so you may find their oval brown exoskeletons during your search.
Bed bugs are small, brownish, flattened insects that feed solely on the blood of animals. Although the common bed bug (Cimex lectularius) prefers feeding on humans, it will also bite other warm-blooded animals, including dogs, cats, birds and rodents. It has done so since ancient times; bed bugs are mentioned in medieval European texts and classical Greek writings back to the time of Aristotle.

Other types of bed bug traps include those that do not rely on humans as bait, but instead use CO2and/or other attractants. CO2 is thus far the most powerful lure for bed bugs, as it is the primary cue they follow to locate hosts. Traps that issue CO2 for a period of time are more expensive than Climbup™ traps, but can effectively trap bed bugs when no host is present, such as in common areas, vacant homes or units, offices, schools, and theaters. Thus they can help confirm infestation and eradication.
Bed bug bites are caused primarily by two species of the insect Cimex: Cimex lectularius (the common bed bug) and Cimex hemipterus.[3] Their size ranges between 1 and 7 mm.[7] They spread by crawling between nearby locations or by being carried within personal items.[2] Infestation is rarely due to a lack of hygiene but is more common in high-density areas.[8][2] Diagnosis involves both finding the bugs and the occurrence of compatible symptoms.[5] Bed bugs spend much of their time in dark, hidden locations like mattress seams or cracks in the wall.[2]
To know it's bedbugs, it's important to find the bugs themselves. Look at bedsheets and mattresses for little spots of blood, rusty-looking stains (crushed bugs), or black dots (bugs' poop). You might see live bugs around the seams or tags of mattresses and box springs, or in cracks of bed frames and other furniture. They can even hide in books, carpet edges, and electrical outlets.
Instead, get written quotes from three licensed exterminators detailing their course of action, including pesticides, traps, and/or heat treatments they'll use and how and where they'll use them. "You should ask lots of questions to the companies you interview, because a good company will answer them and will never pressure you to make an appointment," says Dunham.
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.
Prepare the room by separating treated from untreated furniture.  This will involve moving all your furniture to one side of the infested room (Remember, you’ve already assessed which rooms you think are infested.  You may not need to do this in every room).  The process is important because if you treat half of the items in a room and leave other areas untreated, bed bugs may return to the previously treated areas from untreated sites. Take all clothes from drawers, infested closets, etc. and double bag them in clear plastic bags (clear bags are easier to see where things are). Also double bag all personal items (toys, papers, books, electronics, CDs, or anything that could serve as a hiding place for bed bugs) and set them aside until they can be carefully treated, cleaned or inspected. 

Units that produce “dry” steam are less likely to damage household goods. Steam must be at least 113 degrees Fahrenheit (F), the minimum temperature to kill bed bugs, and care must be taken to reduce pressure so that bed bugs are not literally “blown away” before they can be killed by the steam. Steaming should be avoided around hazards such as electrical outlets.

When you return home, quarantine your bags. Decontaminate your luggage and clothing by putting your entire suitcase into a large chest freezer (if you have one) for four days, suggests Gondhalekar, before bringing them back into your home. Extreme hot or cold temperatures kills bed bugs. You can also put your clothes in the dryer on a hot setting for 30 minutes, and try steam cleaning your luggage and clothing.


It is also recommended to put infested items, such as a mattress, in a sauna that reaches temperatures of upwards of 170° Fahrenheit. Similarly, they also perish in extremely cold temperatures so mattresses and other items can be cleansed of these bugs with the use of plastic wrap and dry ice. Cover the items with large plastic tarps and carefully insert dry ice, and then secure. The extreme temperature will naturally fumigate the pests.
Discard affected items. In some cases, infested mattresses and box springs will need to be discarded. Since bed bugs can disperse throughout a building, it also may be necessary to inspect adjoining rooms and apartments. Pay it forward: chop up and/or damage the items you discard so nobody will be tempted to take them home and spread the problem further.[17]
Before you begin your own bed bug treatment, you will need to prepare the room or rooms where bed bugs have been found, in addition to rooms that share walls with the infested rooms. Remove any items in the room that you absolutely cannot treat or that have already been treated. Cover items that will be removed from the room in plastic bags before moving to the next room to prevent any unseen bed bug from infesting another room.

But the bites will look different from person to person, and some people won’t develop any reaction whatsoever. “The same bedbug could bite two different people and one could have no reaction at all and the other can have an extreme reaction with a swollen arm or itchy rash,” says Eric Braun, a board-certified entomologist and business manager for the national pest control company Rentokil Steritech, who is based in Redding, Pennsylvania. Some people end up developing a rash that looks like eczema. (5)
Waking up with bites might be the first indicator that you have a bed bug problem. Their bites are often arranged in lines or clusters on the face, neck, arms or hands. Where there are bed bugs in large numbers, you might smell a sweet, musty odor (from the bugs’ scent glands) or see rust-colored spots on your bedding or mattress caused by bed bug blood or excrement. If you look closely, you might see adult bed bugs themselves, usually in mattress folds or seams or on the wall behind the headboard. Bed bugs prefer to stay close to their food source and are typically found hiding out within 1 to 5 ft of infested beds or furniture.
Great read and very helpful info. However, when you describe how to use essential oil sprays for bed bug treatment, it would be most helpful if you included the amount of water used to mix with the oils. Simply stating to use “a small spray bottle filled with water” isn’t a very good description. A quick search for “small spray bottle” will get results for a wide range from 2-ml to 16-ounce bottles, all classified as small. This makes for a rather potent mixture to an extremely weak mixture.
DIY heat treatments most often just drive bed bugs deep into wall voids and hard-to-reach spaces in a structure. When the heat is turned off, the bugs return to living and sleeping areas. It has no impact at all. But, in worst case scenarios, where desperate people have gone to greater lengths to destroy these tormenting pests, it has resulted in damage to belongings, the death of pets, structural fires, and in tragic cases, a loss of human life.
Bed bugs are very hardy insects. Both adults and nymphs can survive prolonged periods without food or under adverse temperature conditions. Adults can live for a year or longer without feeding and can survive over winter in an unheated building. Nymphs are not as hardy as adults, but they can survive for considerable periods under adverse conditions.
Don't assume your bites are bedbugs. Bites can be hard to identify, even for doctors. Rule out mosquitoes, fleas, mites, and biting gnats by conducting a visual inspection. It's best to collect and identify bedbugs to confirm bites. Look for the bugs themselves or their bloodstains, especially along the seams of mattresses. Further, look for dark spots of insect waste where bedbugs might crawl into hiding places on furniture, walls, and floors.

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]
They come out at night to find food, which in their case means blood. Bedbugs have a special ingredient in their saliva (spit) that keeps blood from clotting while they feed, typically at night in areas where people sleep. After their blood meal, bedbugs don't stay on a person for long. Instead, they hide nearby, often in clothing or luggage, allowing them to spread when belongings move to another location.
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.
