One method of applying freezing temperatures to bed bugs entails the use of carbon dioxide (CO2) applied as “snow” with a portable application device, i.e., Cryonite™. When applied directly onto bed bugs, the frozen CO2 will kill them. However, this method is similar to using contact pesticides, that is, there is no residual activity. It can kill only as many bed bugs as the applicator can find. The advantage of using this type of freezing device is that bed bugs may be killed quickly and without the use of more hazardous pesticides. Again, this is not a stand-alone treatment, and it is recommended that it be used as a supplemental to the application of residual pesticides and/or other means of control.
Bedbugs do, however, have a unique bite pattern. Although some bites may appear alone, most bites occur in a row of three to five bites (termed "breakfast, lunch, and dinner") or in a cluster of red bumps (a rash called bedbug dermatitis). The bites often appear in a zig-zag formation, but may appear in a straight line if the bugs bite you in the morning.
Treatment for bedbug bites is typically supportive. Local antiseptic lotions or antibiotic creams can be applied for secondary infections, whereas corticosteroid creams and oral antihistamines can be used for allergic reactions. Bedbugs can be eliminated through the use of permethrin insecticides, baited traps, special bedbug-free beds, and bed nets. Homemade methods, such as wrapping duct tape around bed legs as shown, may be effective, but bedbugs have been known to climb other objects and then fall down onto a bed.

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.
To check for signs of a bedbug infestation, Dr. DerSarkissian says that you may notice rusty-colored spots on bed linen and mattresses. These spots could be either blood stains or bedbug excrement. You may also find shed skins around bed frames, mattresses, and other hiding places. Also, a musty smell is usually present where a large number of bed bugs are living.4
We are often asked, "How do you kill bed bugs?" While we would love to give a simple answer, this is actually a loaded question. There are many ways to kill a bed bug but, if you want to kill all of the bed bugs in your home or business, it is important to pay attention to the details. Here are some ways you can kill bed bugs, and what you should know about each.
To kill bed bugs is to save yourself from a lot of problems. However, before you could eliminate them, there are several preparatory steps that you first have to take so you will know how to get rid of bed bugs. With all those problems and pre-elimination work, many think it is better to prevent the pests by using bed bug spray than to let them in and just get rid of them.
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.
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”.
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.
Bedbug infestations seem to be increasing around the world at an alarming rate, possibly due to insecticide resistance. [1] Resistance to pyrethroid insecticides is already widespread in the United States. The bedbug occurs in aggregations when conditions are favorable, but the arthropods disperse when conditions are unfavorable. [2] Active female dispersal can potentially lead to treatment failures and should be taken into account when using control methods.
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.
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.
To use sprays effectively to eliminate all traces of bed bugs, you need to know the signs of a bed bug infestation. The first sign that you may have bedbugs are some itchy bite marks on your skin when you wake up in the morning. Dr. Carol DerSarkissian on WebMD says that the bites from bed bugs cause red itchy bumps on the skin.3 You can learn about their other signs and symptoms in my articles on what do bed bug bites look like.
Today, bedbugs can be found in every State in the United States, and almost every city. Bedbugs are so common now that the federal government considers them almost "epidemic". The National Pest Management Association has declared war on bed bugs and has held bedbug meetings all across the Nation to help educate pest control companies in an effort to help control them.
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.
