In the case of beds, a more economical option is to encase both the mattress and box spring in a protective cover like those used for allergy relief. Encasements specifically designed to help protect against bed bugs are available through retail or pest control firms. Higher quality ones tend to be more durable and comfortable to sleep on. Once the encasement is installed and zipped shut, any bugs which happen to be inside are entombed and eventually will die. Encasements also help protect newly purchased beds, and make it easier to spot and destroy any bugs residing on the outer surface during subsequent examination. Encasements will not, however, keep bed bugs from crawling onto a bed and biting a sleeping person.
Claude suggested a “hot as you can stand it” shower or bath to treat the bites. The itching will intensify for a few seconds, but then there is the relief which lasts for many hours. Some believe that the heat from the water overloads the ends of your nerves and prevent them from telling your brain to itch. Some think that the heat causes your body to release more histamine than usual and thereby less histamine around the bite. Whatever the reason, it’s commonly used as a solution to itching caused by bites.
A number of other symptoms may occur from either the bite of the bed bugs or from their exposure. Anaphylaxis from the injection of serum and other nonspecific proteins has been rarely documented.[5][10] Due to each bite taking a tiny amount of blood, chronic or severe infestation may lead to anemia.[5] Bacterial skin infection may occur due to skin break down from scratching.[5][11] Systemic poisoning may occur if the bites are numerous.[12] Exposure to bed bugs may trigger an asthma attack via the effects of airborne allergens although evidence of this association is limited.[5] There is no evidence that bed bugs transmit infectious diseases[5][7] even though they appear physically capable of carrying pathogens and this possibility has been investigated.[5][3] The bite itself may be painful thus resulting in poor sleep and worse work performance.[5]
Bed bugs will also succumb to cold temperatures below 32°F, but the freezing temperatures must be maintained for a longer period (e.g., one to two weeks). Consequently, heating tends to be a better option throughout much of the country. Efforts to rid entire dwellings of bed bugs by raising or lowering the thermostat will be unsuccessful, although pest control firms are able to achieve lethal temperatures with supplemental heaters (see the subsequent section entitled "Heat Treatments" for more details). 
However, always remember that these simply treat the problem and do not get down to the root cause. You will still need to take steps to get rid of them! Here are a couple home remedies to get rid of bed bugs that have been extremely helpful to the community. I encourage you to take a look at that article if you are serious about removing them properly.

It was stated in 2012 that no truly effective insecticides were available.[6] Insecticides that have historically been found effective include pyrethroids, dichlorvos, and malathion.[4] Resistance to pesticides has increased significantly over time, and harm to health from their use is of concern.[3] The carbamate insecticide propoxur is highly toxic to bed bugs, but it has potential toxicity to children exposed to it, and the US Environmental Protection Agency has been reluctant to approve it for indoor use.[33] Boric acid, occasionally applied as a safe indoor insecticide, is not effective against bed bugs[34] because they do not groom.[35]

Bed bug bites do not typically require treatment. It is best to clean the bite site(s) with soap and water and avoid scratching so as to prevent secondary infection. Progressive swelling, warmth, tenderness and sometimes (albeit rarely) fever may be signs of secondary infection, which should be managed with antibiotics as appropriate. Much more common are complaints of itching. For how to treat bed bug bites that cause severe itching, topical steroid creams or oral antihistamines may offer relief from itching and thus decrease the risk of infecting the bite site.
One bed bug will usually take more than one bite. Once a bed bug inserts its mouthparts and finds a suitable blood vessel, it will begin feeding. However, finding the right blood vessel may take more than one injection into the skin. In addition, bed bugs are very sensitive to movement by the host they are feeding on. Therefore, if a sleeping person moves, a feeding bed bug will probably withdraw its mouthparts and begin its search for a blood meal on another part of the body. It’s important to remember that the number of bites a person receives is not indicative of the number of bed bugs that feed on that person.
