The answer to 'why is my bed bug bites' is that you likely have a bed bug infestation in your home. Bed bugs are small insects that feed on human blood, and their bites can cause itchy, red welts on your skin. Common signs of a bed bug problem include finding the bugs themselves, seeing blood spots on your sheets, and experiencing unexplained bites, especially around your neck, arms, and other exposed areas.
Bed bugs can be difficult to get rid of, as they hide in cracks and crevices and can spread quickly. If you suspect a bed bug problem, it's best to call a professional pest control technician who can properly identify the issue and recommend the right treatment. DIY methods like using over-the-counter sprays may not be effective and could even make the problem worse.
