Bed Bug

Bed bugs are small, flat, wingless insects that feed on blood, usually at night while people sleep. They hide in mattress seams, furniture and cracks, which makes them notoriously hard to spot and remove. Like grasshoppers, they grow through simple metamorphosis, molting through several nymph stages and needing a blood meal before each one. Our guide to the bed bug life cycle walks through every stage of development, from tiny egg to adult.
