Adult bed bugs are about the size of an apple seed and can be gray or brown but turn red after a blood meal. They can survive up to a year without feeding. Females lay 200-500 eggs in a lifetime, which are cream-colored like small grains of rice.
Identifying bed bugs includes looking for specific features. Nymphs, or juvenile bed bugs, are smaller and pale, becoming brown as they mature. Bed bugs possess six legs, short antennae, and lack wings, making them adept at crawling but not flying. They are nocturnal, primarily feeding on human blood at night, which may leave itchy, red welts on the skin.
Preventing bed bug infestations involves vigilance and cleanliness. Regularly inspect mattresses, bed frames, and furniture for signs of bed bugs. Vacuum frequently and wash bed linens in hot water. Using protective mattress covers can help as well. When traveling, inspect hotel rooms thoroughly and avoid placing luggage on beds or floors.
Understanding bed bug characteristics is vital for effective prevention. In the next part, we delve into effective treatment methods and how to detect an infestation early, ensuring your home remains bed bug-free.
