Bedbugs are a species of insect known as cimex lectularius (literallycimex is Latin for bug and lactularius is Latin for bed). There is a second common species of bedbugs known as cimex hemiptera. These are known as the tropical bedbugs, staying within 30 degrees of the equator. There are published reports, many without supporting evidence, that each of the common bedbug species has chemically different saliva. Some researchers, however, have found no difference in the reactions caused by each species.
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. 
Considering how time-consuming and costly it can be to eradicate bed bugs, it’s prudent to take precautions and avoid infestations in the first place. Householders should be vigilant when acquiring used furnishings, especially beds and couches. Discarded items should be avoided, and secondhand articles should be examined closely before being brought into the home. Look carefully in the folds and seams of furniture for signs of bed bugs (see the previous section entitled "Description and Habits" for more details). There is no reason to stop shopping in consignment stores, yard sales, etc., but it would be prudent to run clothing and fabric items through the washer or dryer before storing them in the home. The risk of acquiring bed bugs from items purchased in antique stores would generally be insignificant.      
The biggest problem with these bites is that, depending on the persons skin and their tolerance to bacteria, their appearance is different on different types of people. I have noticed in the past that if I get bitten by a mosquito, I get a rather large red mark (even without scratching), whereas my husbands skin hardly shows any signs of the bite.
Prior to World War II, infestations of bedbugs were common; however, after the widespread introduction of the use of the insecticide DDT in the mid-20th century, bedbug infestations became much less common. The recent resurgence in infestations of bedbugs worldwide is thought to be related to several different factors, including the increase in international travel, dense urban living conditions, insecticide resistance, and new, ineffective pest control measures.
Hello there Trish from Reno we found bed bugs oh my gosh, I am am the only one who has been getting bit last yr on my feet this yr on my hands. My husband saturated our mattress with rubbing alcohol baseboards and I am washing everything tomorrow should we spray our entire you’re house too even our cloth furniture? What else should we do. Thanks you for this site. Sleepless in Reno…
While cleaning up infested areas will be helpful in controlling bedbugs, getting rid of them usually requires chemical treatments. Because treating your bed and bedroom with insecticides can be harmful, it is important to use products that can be used safely in bedrooms. Do not treat mattresses and bedding unless the label specifically says you can use them on bedding.
