signs of bed bugs
Red stains on bedding or mattress.
It's possible to kill bed bugs while they are feeding or just after when you move around or roll over in bed. The red stains are left on your bedding or mattress when bed bugs are crushed. This is easy to see if you have light colored bedding but is still possible to see even on darker bedding.
Bed bug feces on bedding or mattress.
Bed bugs will leave a blackish looking trail of fecal specks on your mattress or bedding. Bed bug feces is pretty much just dried blood. In fact, if you wet it very carefully with a small amount of water, it may turn red again and look like blood.
You'll often find feces in mattress seams and other cracks and crevices. Bed bugs are small and flat and often remain hiding in such places. Also check seams in pillows, furniture cushions, floor moldings and baseboards for both bed bugs and bed bug feces.
Bed bug exoskeletons (or eggs) in bedding, on mattress,couches or common areas.
Exoskeletons are the hard shell of a bed bug. This shell protects the bed bug and provides the structure for its muscles and organs. When the bed bug grows, it does so through a process called molting.
During the process of molting, the outer layer of the bed bug's exoskeleton (called the cuticle) cracks and is sloughed off. This allows the bed bug to expand. A new shell will harden and the bed bug will be at a new size. They leave the exoskeletons behind. When you see them, it is an indication that bed bugs are there.
Check in the same places you would for bed bug feces: seams of pillows and cushions, folds in bedding, baseboards, etc.
An unusual, sweet aroma.
It is said that when you crush bed bugs or have a heavy bed bug infestation, you can smell a sickly sweet aroma.
Take all of it with a grain of salt. If you don't have much of an infestation, chances are you might not smell anything. But if you are in your home and notice a new smell that seems out of place, it might be something to keep in mind.
It is common for people to mistakenly attribute the marks to something besides bed bugs. People going to the doctor with bed bug bite marks are sometimes told the marks are scabies or allergic rashes. Often these people are prescribed steroids or antihistamines. This is why it's important to not only pay attention to the timing of the symptoms.

Bed Bug Bite Symptoms and Misdiagnosis
Bed bugs tend to leave bite marks in a straight line or trail. Often appear in a series of 3 or 4 bites. Bed bug bites often resemble mosquito and flea bites.
The body's reaction to a bed bug bite will vary from person to person. For most people, the reaction is limited to localized itching and swelling at the site of the bite. If the itching sensation is intense and you scratch the bites, there is a chance you could open the skin which exposes you to risk of infection. Some people however have an allergic reaction and require medical treatment.
