Bedbugs are small, reddish-brown, wingless insects that feed on human blood, typically while people sleep. They hide in mattresses, bedding, furniture, baseboards, electrical outlets, and even behind wallpaper, making them hard to detect. Bedbug bites often appear as red, itchy welts in a line or cluster and can lead to allergic reactions, secondary skin infections from scratching, and psychological stress due to sleep disruption. These pests reproduce quickly, and their eggs are resistant to many over-the-counter treatments, making professional pest control essential for complete eradication.
