Bedbugs are very flat, allowing them to hide in tiny holes. A crack wide enough to fit the edge of a piece of thin cardboard card can harbor bedbugs. The most common place to find bedbugs is the seams of a bed, crevices of the mattress, box spring, bed frame and headboard.
Bed bugs are also known as louse, mahogany flat, crimson rambler, heavy dragoon, and redcoat. A recent increase in bed bug infestation is likely due to increased resistance to pesticides used to eliminate bed bugs.
