There are many different ways to treat for bed bugs below are some of the treatment options that are available to you.

Chemical Insecticide Treatments

The use of chemical insecticides is the most prevalent method of bed bug control worldwide. Depending on where you live in the world, the choices of insecticides vary.  These products, many of which developed in the late 70’s & 80’s, work by opening sodium ion channels in neurons at the insect’s nerve axon causing them to fire spontaneously ultimately leading to spasms and expiration. These products, when used properly, generally have had good safety records.Some of the other available insecticides include mitochondrial poisons such as chlorfenapyr, and desiccant dusts such as silica or limestone which dehydrate the insect. Insecticide treatments are tedious, labor-intense, and often-times repetitious. They’re costly and involve a lot of preparation prior to and after the application is made. Success heavily weighs on the diligence of the pest control service technician. This work involves heavy lifting and an acute attention to detail. Round the Clock  techs must also be able to effectively communicate with customers, explaining every aspect of preparation and post-treatment actions required.
Readily available; effective if properly treated; affordable for most.
Resistance problems with some insecticides; heavily dependant on the applicators diligence; insecticides objectionable to some; high treatment failures especially in homes with lots of clutter.

Steam Treatments

Steam is a viable option for some situations. Direct contact with an appropriate steamer will kill bed bugs and eggs. This is tedious work, but if done methodically it can be an effective method of control. Hospitals and nursing homes, where rooms are institutional (and much less complicated than an apartment for example) may have greater success using this method.
Non-chemical; anyone can do it if diligent; effective as long as direct contact is made to the bug or egg.
Because steam must make direct contact with the bug or egg, there’s a high probability that some will be missed, if direct contact isn’t made.

Fumigation Treatments

Some people confuse aerosol “bombs” with fumigation, they are not the same. True fumigation is serious work that involves a tremendous amount of human and financial resources. In the most general sense, fumigation is the introduction of gases to confined spaces that permeates all contents to achieve a 100% kill of all living creatures inside.
Generally considered 100% effective.
Has no residual to prevent future infestations.

Thermal Remediation (Heat Treatments)

Thermal remediation involves introducing a high temperature (heat) to an area for a prolonged period of time to reach a thermal “death” point. Generally heat treatment professionals strive for a temperature of 120-140F for a prolonged period of time to kill bed bugs and their eggs. It’s not enough to simply raise the temperature, the air must be moved to achieve uniform saturation of the area. It may take many hours, sometimes in excess of 24 hours to uniformly saturate the treatment area.
Very little preparation required.
Expensive, a risk of premature aging of some building materials; risk of fire sprinkler activation; can be challenging in multi-family housing properties.

Cryonite® (aka Rapid Freeze) Treatments

Cryonite is a system that utilizes carbon dioxide to produce a rapidly deployed “snow” delivered through a patented Cryonite gun. As with steam, a direct contact with the bug or egg is required to assure effectiveness.
Snow penetrates some crevices easily; low cost materials may make it affordable to some in certain areas.
Direct contact with snow is required.
