Bed bugs are a type of insect that feed on human blood, usually at night.[7] Their bites can result in a number of health effects including skin rashes, psychological effects and allergic symptoms.[5] Bed bug bites may lead to skin changes ranging from invisible to prominent blisters.[1] Symptoms may take between minutes to days to appear.[2] Itchiness is common, while some may feel tired or have a fever.[2] Typically, uncovered areas of the body are affected and three bites occur in a row.[2] Bed bugs bites are not known to transmit any infectious disease.[5][7]
It takes time and persistence to get rid of bed bugs, and in some cases, the cooperation of landlords, neighbors and others. It can be physically and emotionally exhausting. It can also be expensive when pest control companies are called in. Just remember - bed bugs are more of a nuisance than a health concern and, with vigilance, you can avoid or deal with infestations.
Buy “say bye bugs” I think its liquid diatemacious earth food grade, I put powder down on my couch took all loose wood off and they were hidden under material sprayed and dusted it with the diatemacious earth kills them on contact, of course you have to do it 10 days. Because even dead they can lay eggs……keep spraying every day, wash bedding in hot water dry at least 45 min on high heat, after you think they are dead, put mattress or furniture in bed bug bag for a year, because they can stay alive for a year without eating…om working on it going on 3 days now!!
In most cases, the only way to say for sure whether it was a bedbug that bit you is to search for evidence of bedbugs living in your home. "Once you start to notice the itchy bites, the second giveaway is the presence of small blood spots on your sheets or mattress, usually resembling patches of rust,” Durham says. Those spots are left behind after a bedbug has been smashed.

Bedbugs are highly resistant to many sprays. There are, however, certain sprays that may be able to kill bedbugs. Check with a professional exterminator about advice using sprays to try and remove the bedbugs yourself. Dead bedbugs usually won't move, may be arched back, or red in color. Ultimately, you may be better off replacing your mattress and bedding and fumigating your home to kill the bedbugs.
Probably chiggers -- they are very small, red mites that usually cannot be seen with the naked eye. They are about as small as the period at the end of this sentence. To stop the itching, use OraJel (usually sold for teething babies), which contains benzocaine (an anesthetic). Also, rub in hydrocortisone cream. To prevent chigger bites, wear long pants and stuff the cuffs into your socks.
Many news reports in recent years have focused on the discovery of bedbugs and their health effects (even in upscale five-star hotels), and a number of lawsuits have been filed by guests of fashionable hotels who awoke to find hundreds of bedbug bites covering their skin. Searching on travel-review web sites regularly reveals information and even photos confirming the presence of bedbugs in numerous hotels.
After bedbugs find a food source, they bite down with their mouths and inject anticoagulant and anesthetic compounds into the skin. Depending on the species, these parasites feed on the host blood via 1 of 2 mechanisms. Vessel feeders directly insert their mouthparts into superficial capillaries, whereas pool feeders damage the superficial tissue and feed on the accumulated blood. As bedbugs feed, their color may change as they swell with the host blood, as shown in this picture of a larval bedbug feeding on a volunteer host.

Some pest control firms also employ commercial steamers or spot-freezing equipment to treat areas where bed bugs are found or suspected. Used correctly, they kill bugs and eggs on contact. Neither method, however, affords residual protection against bed bugs which may have been missed. Steaming and spot-freezing equipment also have limited ability to penetrate fabric, wood, and other materials where bed bugs often reside. 
Once the mattress and box spring are dry, encase them in sealed bed bug encasements. Encasements are crucial, as they prevent bed bugs from entering or escaping the mattress and box spring, cutting off key hiding places. Remember to leave the encasements on for at least 18 months to ensure that any bed bugs already inside have starved to death. Once the encasements have been applied, you can put your mattress and box springs back on your treated bed frame, and put your laundered bedding back on your bed.
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.

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.
Pay attention to when the bites occur. Consider, for example, if you notice the bites after waking up when previously you hadn't noticed them. However, this can also be difficult to determine because each person's reaction time can vary significantly. Symptoms that result from the bite can manifest at any point from a couple of hours to more than a week after the bite occurred.
Wash bedding and clothing (hot water and hot drying cycle for 30–60 minutes), vacuum cracks and crevices, and freeze articles that may have been used as hiding places for bedbugs may reduce infestation until extermination can be performed. Vacuum with special attention to cracks and crevices in furniture, equipment, walls, and floors. Vacuuming some talcum powder will reduce the chance that the bugs will crawl out of the vacuum cleaner. Dispose of the vacuum cleaner filter and bags in a tightly sealed plastic bag. 

Bed bugs can survive more than a year without feeding, but most adults and nymphs probably do not live more than six months without a meal. This ability lets them wait for transient hosts that periodically inhabit camp cabins, apartments and temporary housing. It also helps them survive transportation. Today, bed bugs “hitchhike” more easily than ever, via public transportation and luggage, and in secondhand furniture, mattresses, bedding and clothing. In multi-unit buildings, bed bug infestations that are not adequately attended to often spread between units with or without human help, making eradication much more difficult and costly.
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.

Don't let the name bedbug fool you. Bedbugs can be found any place humans rest and lounge and nearby. Bedbugs can be found under school desks, restaurant benches, on computers in the library, chairs, hospital beds and curtains or on a store wall. The same goes for carpets. Many times a brush against a wall in on infested area can lead to bedbugs in the home. Bedbugs are very good at clinging onto fabrics. Transportation hubs such as airports, train stations and bus terminals are also key infestation stations to be wary of.[4]

* Typically used for control of wood-destroying organisms, true fumigation of structures is occasionally performed for bed bug control. Fumigating a structure involves “tenting” it, i.e., draping and sealing it with tarps so that the fumigant, a poisonous gas, can be applied into and contained within the structure where it penetrates the contents and kills all pests within. Like whole-room heat treatments, fumigation has no lasting effect (it leaves no pesticide residue), is labor-intensive, and can damage contents. It is also more expensive, especially in northern states where fumigations are done less frequently. The advantage of fumigation over heat treatment may be that fumigation is more likely to kill all the pests within a structure.

To treat an allergic reaction, the doctor may prescribe an antihistamine, corticosteroid, or epinephrine injection. If the area is infected, he or she might prescribe an antibiotic or recommend an over-the-counter antiseptic. Finally, if it’s severe itchiness that you’re dealing with, applying corticosteroid or taking an antihistamine in pill or liquid form may be able to help.
Some bed bug species are parasites of bats or birds, and may bite people if the wild hosts are no longer available. Although similar in overall appearance, the species of bed bugs that normally feed on bats, swallows, chimney swifts, pigeons or other wild hosts can be differentiated from those that prefer humans. Entomologists and knowledgeable pest managers can make this determination. If bat bugs or bird bugs are present, roosting and nesting sites should be the primary focus, and the animals should be removed and excluded from the building.
