Bed Bug

Primarily indoor environments, hiding in mattress seams, bed frames, and furniture crevices

Obligate blood-feeders, primarily targeting humans but also other warm-blooded animals

Nocturnal insects that emerge from hiding spots at night to feed. They undergo incomplete metamorphosis (egg, nymph, adult phases) and can survive months without a meal.

Highly problematic domestic pests; bites cause itching, allergic reactions, and sleep deprivation. They do not transmit diseases but infestations cause significant psychological and economic stress.
