What does it mean when you find a lot of bird poop in your house?

Finding a lot of bird poop in your house typically indicates that birds are nesting or roosting nearby, possibly in your attic, eaves, or even inside if Windows or doors are left open. This situation can signal a potential pest issue that may require removal of the birds and cleaning of the droppings, as they can pose health risks and damage property. It may also suggest a need to secure entry points to prevent future infestations. Regularly cleaning and monitoring for signs of birds can help mitigate these issues.
