Bed bugs (Climex lectularius) have been around since ancient times. The current resurgence is suspected to be due to increased traveling, population growth, restrictions on certain control products and lack of awareness.
Today, it is estimated that one out of five Americans has had a bed bug infestation in their home or knows someone who has encountered bed bugs at home or in a hotel.
Adult bed bugs are small, oval and resemble ticks in size and shape. Adult bed bugs and older nymphs are usually ¼ inch long; while newly-hatched immature bed bugs are clear and very tiny, ranging from 1.3 to 4-5mm.
Unfed bed bugs are flat, oval and brown. Fed bed bugs become swollen with blood, elongated and reddish brown.
