Lutikad

Lutikad, scientifically known as Cimicidae, are a small family of endoparasitic insects belonging to the order Hemiptera. They are commonly referred to as bed bugs. The most well-known species is Cimex lectularius, the common bed bug, which primarily feeds on human blood. Other species exist that parasitize bats, birds, and other warm-blooded animals.

These insects are typically reddish-brown in color, oval-shaped, and flattened dorsoventrally. Adult bed bugs are about 4-5 millimeters in length, roughly the size of an apple seed. They lack wings and are unable to fly, but they are capable of moving quickly across surfaces. Their life cycle includes five stages: egg, nymph (which molts five times), and adult. Nymphs resemble smaller adults and also feed on blood.

Bed bugs are primarily nocturnal, emerging from their hiding places to feed while humans are asleep. They are attracted to their hosts by heat and carbon dioxide. After feeding, they return to their sheltered locations, which are often in cracks and crevices near sleeping areas, such as mattresses, bed frames, headboards, and furniture. Bites from bed bugs can cause itchy red welts on the skin, though reactions vary among individuals. While they can be a nuisance and cause discomfort, bed bugs are not known to transmit diseases to humans.

Infestations are typically acquired through travel, bringing infested luggage or items into a home. They are notoriously difficult to eradicate, often requiring professional pest control measures involving insecticides and thorough cleaning.
