The most noticeable sign of a bed bug problem may be found on your skin. Bed bug bites are typically small and red, and can be itchy. The bite might also become inflamed. However, not all people react to bed bug bites by experiencing a red spot or itchy area. Some people show no signs of bed bug bites and have no physical reaction at all, so many times people aren't even aware they have a problem. That's why it's important for people everywhere to inspect for bed bugs regularly.
One hallmark of a bed bug problem is waking up with a very distinctive bite pattern on your skin. According to the NHS, bed bug bites often occur in a line. This means that you might be able to differentiate them from the bites of fleas or mosquitoes, which don't normally appear in such a formation.
If you detect an unfamiliar and musty odor in your home, it could be a sign of a bed bug infestation. An unpleasant, musty scent in your bedroom could signal the presence of the pesky critters. This is because bed bugs release pheromones that can be quite strong when large amounts of the insects are present.
If you find dark spots on your mattress or bed sheets, the stomach-turning reason could be bed bugs. Bed bugs frequently leave fecal stains on bedding or wherever they have gathered in large numbers, according to WebMD. These spots often smear when touched and can have an unpleasant odor.
Bed bug shells appear as white, husk-like specks, according to the NHS. They can sometimes be mottled and are produced when the bugs shed their skin as they grow. Though you might find these shells in your mattress or along your headboard, it's also possible to uncover them between your sofa cushions or under furniture. The insects also tend to prefer fabric or wood over plastic or metal.
