One of the most common and earliest signs of a bed bug infestation is the appearance of red, itchy bites on the skin. These bites often occur in a line or cluster and can be found on any exposed skin, such as the arms, legs, neck, or face. The bites are usually small, raised bumps and may be surrounded by a red or pink rash. If you wake up with unexplained bites on your body, it could be a sign of bed bugs on your mattress.Red, itchy bites on the skin
Bed bugs feed on blood and when they bite, they leave behind small drops of blood. This can often be seen on your sheets, pillowcases, or mattress as small, red stains. These blood stains may be more noticeable if you move around in your sleep or if the bed bugs have been disturbed. If you start to notice these small blood stains on your bedding, it could be a sign of a bed bug infestation.Small blood stains on sheets or mattress
Another sign of a bed bug infestation is the presence of dark spots or smears on your mattress or bedding. These are often the bed bug's fecal matter and may appear as small, dark spots or streaks. These spots may be found on your sheets, pillowcases, or mattress and can be a good indicator of where the bed bugs are hiding. If you notice these dark spots on your bedding, it's important to take action and inspect for bed bugs.Dark spots or smears on mattress or bedding

If the infestation is severe, you may be able to see the bed bugs themselves on your mattress or bedding. Adult bed bugs are small, about the size of an apple seed, and are reddish-brown in color. They may also appear flat and oval-shaped.
