Bed bugs, small insects with flat, oval bodies that are reddish-brown in color, are notorious for infesting homes and feeding on human blood. They typically hide in cracks and crevices, making them difficult to detect. Common infestation sites include mattresses, bed frames, headboards, upholstered furniture, baseboards, and even behind wallpaper or electrical outlets. Bed bugs are often transported through luggage, clothing, or secondhand furniture, leading to new infestations in previously unaffected areas. Their ability to reproduce quickly means that prompt action is essential to prevent a small problem from becoming a larger one. Treating only visible bugs will not suffice; it's important to address all potential hiding spots and any eggs present to fully eliminate the infestation.
