Which pest is described as small, reddish brown, wingless, oval, and flat?

The correct identification of the pest as small, reddish-brown, wingless, oval, and flat leads to bedbugs. Bedbugs are known for their distinct shape and color, which allows them to hide easily in small crevices and seams of furniture, bedding, and other household materials. Their flat bodies enable them to fit into tight spaces, which is a characteristic that aids in their concealment from potential threats.

Understanding the physical attributes of bedbugs is crucial in pest management. The reddish-brown coloration arises from their blood-feeding habits, as they take on a darker hue after feeding. Recognizing their appearance can help in effectively diagnosing an infestation and implementing appropriate control measures to eliminate them.

The other options provided do not possess the same defining characteristics. Fleas are typically more elongated and have strong jumping abilities, making them quite different from bedbugs. Ants have a segmented body and are more varied in size and color, while mites often are much smaller, and their appearance can vary widely depending on the species. Thus, knowing the unique traits of bedbugs is essential for accurate identification and treatment in pest control.
