Which of the following pests is known for its biting behavior?

The identification of fleas as pests known for their biting behavior is accurate. Fleas are small, agile insects that are primarily parasitic and feed on the blood of mammals and birds. Their biting behavior is characterized by their strong mouthparts, which are adapted for piercing skin and consuming blood. These bites can result in irritation, allergic reactions, and can transmit diseases in some cases.

In contrast, while bees can sting and cause pain, they do not bite in the same manner that fleas do. Houseflies, on the other hand, primarily feed on liquid substances and do not bite. Ants have mandibles that can bite, but their primary behavior is to scavenge, and not all species are known for biting as a predatory or parasitic method as fleas are. Therefore, the behavior and feeding habits of fleas distinctly fit the description of pests known for biting.
