Which statement about bats can be a nuisance?

• A. They pose no nuisance and never cause disturbances
• B. They are always beneficial and never a health risk
• C. They never roost inside buildings
• D. They can be a nuisance, creating loud noises

Answer: (D)

Bats can be a nuisance when they roost in or near living spaces and when they fly around at night. Their presence in attics, under eaves, or other sheltered spots can produce audible rustling, squeaks, and fluttering sounds, especially from large colonies. Even though they’re beneficial for insect control, that nuisance aspect comes from the noise and from issues that can accompany roosting, like odor or droppings (guano) that may require cleanup and pose health considerations. So the statement that they can be a nuisance, creating loud noises, reflects a realistic and common impact of bats in built environments. The other ideas—being never a nuisance, being always beneficial and free of health risk, or never roosting inside buildings—don’t fit because bats can and do cause disturbances, can roost inside structures, and can carry health concerns even though they’re also beneficial to ecosystems.
