Bed bugs are small, parasitic insects that feed on the blood of humans and animals. They are nocturnal and tend to hide in mattresses, furniture, cracks, and crevices during the day. Although not known to transmit diseases, their bites can cause discomfort, allergic reactions, and psychological stress.

Cycle
Bed bugs undergo incomplete metamorphosis, with the following stages:
1. Egg – Small, white, sticky eggs laid in hidden areas.
2. Nymph – Passes through 5 instars (stages), feeding on blood at each stage.
3. Adult – Oval, reddish-brown, and 5-7 mm long. Can live several months and lay hundreds of eggs in a lifetime.
Each stage requires a blood meal to molt. Under optimal conditions, the life cycle from egg to adult takes about 5-6 weeks.
