Bed bug females lay between 200 and 500 eggs during their lifetime in batches of three to four eggs per day. These eggs hatch after 6 to 17 days. Nymphal bed bugs molt five to six times before becoming adults. Under the best conditions, the life cycle is complete in four to five weeks, but since ideal conditions are rarely found it can take four to five months. Adult bed bugs can live 10 months or more without food. Nymphal bed bugs are known to survive for more than two months without feeding.
Bedbug bites, like all insect bites, can become infected through excessive scratching, as underneath the fingernails lies a host of bacterial pathogens. If your bites become infected, they will appear red and swollen, feel tender and may drain pus. Typically there will not be a fever unless a substantial area of the skin is involved. If you experience any of these symptoms, you must seek medical attention as it points to a secondary infection. Your physician may prescribe antibiotic therapy or, if the infection is mild, an antiseptic medication that you can buy without a prescription.
Bedbug infestations affect both sexes and people of all ages and races in the United States and globally, particularly in poor regions of the world.  The reported rate of bedbugs (Cimex hemipterus) was 37.5% in children's beds from a rural region of Gambia. Recently, bedbugs were allegedly reintroduced from abroad into Seoul, Korea, because there had been no reports on bedbugs in Seoul for more than 20 years. 
Some oils like tea tree and neem oil can't kill bedbugs, but they work well to repel them. Tea tree oil is an extract from the Melaleuca alternifolia plant—it can cause various health problems with pet birds, cats, and small dogs. If there are pets in the house, look for other safer choices. If you use the oil, apply it in small quantities to the skin to repel bed bugs. Since bed bugs are active at night, apply it before bedtime.
Stripping and vacuuming the mattresses and box springs, and encasing them. Double bag your bedding and wash in hot water and dry for at least 30 minutes (discard the inner bag after putting bedding into the washer, as it could have bed bugs). After vacuuming suspected bed bugs from the bed, take your vacuum cleaner outdoors and remove and discard the bag. Purchase a good quality set of bed-bug-proof encasements for your mattresses and box springs. Bed bug-proof encasements are fabric sacks into which you slide your mattress or your box spring. The zippers on bed bug encasements are designed to be tight enough to prevent even the smallest life stages of the bed bugs from escaping. Also, good bed bug-proof encasements are woven to prevent bed bugs from biting you through the encasement. A good encasement will trap all bed bugs in the mattress and box spring inside, and will be smooth on the outside, providing few places for bed bugs to hide. Sears, Target, Walmart and other stores may sell bed bug-proof encasements, but these can also be purchased online. A good place to look for different brands and reviews of mattress encasements is Amazon.com (whether you buy there or at a local store). Go to http://www.amazon.com and search for “bed bug mattress protectors”.
Adult bed bugs are brown, 1/4 to 3/8 inch long, and have a flat, oval-shaped body. Young bed bugs (called nymphs) are smaller and lighter in color. Bed bugs hide in a variety of places around the bed. They might also hide in the seams of chairs and couches, between cushions, and in the folds of curtains. They come out to feed about every five to ten days. But they can survive over a year without feeding.
It’s perfectly natural to want to eliminate a bed bug infestation without spending a ton of money on professional-grade products or a treatment by a pest control operator. When people discover that they have bed bugs, they often turn to do-it-yourself recommendations from discussions on the Internet. These suggestions might include household items, some of which are recommended more often than others. Let’s take a closer look at some of the most popular items and how they might be used against bed bugs:
First up is the most commonly recommended tool by far: rubbing alcohol diluted in water. This is suggested because alcohol can kill bed bugs on contact, and evaporates shortly after, so it’s considered safe for use pretty much anywhere in a home. A recurring theme in these recommendations are household items that are considered to be safer for people than mainstream chemicals.
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.
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.
