How many eggs can a flea lay in its lifetime?

A female flea can lay around 2,000 eggs throughout her lifetime, making this the correct answer. Fleas reproduce rapidly, which is a significant factor in their population growth. The eggs are typically laid in the environment where the flea resides, often in the host's bedding or in carpet fibers, making it important for pest control efforts to focus on both adult fleas and their eggs to effectively manage an infestation. Understanding the reproductive capacity of fleas is crucial for anticipating the extent of an infestation and implementing proper control measures.
