Bed bugs have a fast and large reproduction nature. On an average, they can reproduce within 200 to 250 eggs at one time, and hatch during an interval between 6 to 10 days. Bed bugs largely live between 4 months to 6 months, and a 1-time treatment is not sufficient to cover the Bed Bug life stages. A 3 times treatment integrated with steam treatment and follow ups across 1.5 to 2 months is usually recommended. Read more here on 6 Questions to Get the Best Treatment for Bed Bugs.
You can make a natural bed bug bite treatment by putting 1 cup distilled water in a spray bottle and adding 10-15 drops tea tree oil. Shake well and spray on areas of skin that have clusters of bed bug bites. Or, you could spray the remedy on a cotton pad and apply to the itchy bumps on your skin. You can also dilutes tea tree oil with a carrier oil, such as coconut oil or sweet almond oil (a few drops of tea tree per one tablespoon of carrier oil).
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. 
The decline of bed bug populations in the 20th century is often credited to potent pesticides that had not previously been widely available. Other contributing factors that are less frequently mentioned in news reports are increased public awareness and slum clearance programs that combined pesticide use with steam disinfection, relocation of slum dwellers to new housing, and in some cases also follow-up inspections for several months after relocated tenants moved into their new housing.
Some firms want beds stripped and furniture moved before they arrive, while other firms prefer to inspect first and perform these tasks themselves. Clutter and belongings on floors (especially beneath beds) must be removed since they impede treatment and afford additional places for bugs to hide. Bedding and garments normally will need to be laundered and/or hot dried (120°F minimum) since they cannot be treated with insecticides. An effective and efficient alternative to laundering is to simply place bedding, clothing, toys, shoes, backpacks, etc., in a clothes dryer set at medium-to-high heat for 10 to 20 minutes. This can be done in lieu of washing and will kill all bed bug life stages.
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.
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.

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.
