bite marks
Bed bugs are known to eat blood rather than dead skin, which is why bite marks are one of the most obvious symptoms of a bed bug infestation.
While small bite marks can often be confused with this common critter, there is a specific pattern to look out for.
Small red dots on your body could be from almost any bug lurking in your room at night, but a number of bites are most likely from a bed bug.
As stated by the NHS, this is the easiest way to tell if you are in fact sharing your bed with these unsavory creatures.
