Bats become a nuisance when they roost in large numbers in human dwellings. The rapid accumulation of guano (bat droppings) is unsanitary, and serves as a fertile breeding ground for a fungal disease called Histoplasmosis, which is transferable to humans who breathe in the fungal spores.
Does one bat in the house mean more? One random bat in the house doesn't always mean anything. Most of the people that call us have had at least two or three instances of bats in the house over the last few years though. Multiple bats in your house is a very strong indication of an infestation. Most bat colonies found in houses are maternal colonies.
How do you find a bat hiding in your house? Bats will most likely land somewhere they can hang—behind curtains or upholstered furniture, on hanging clothes, or in house plants. Carefully place a plastic tub or similar container over them. Gently work a piece of cardboard or stiff paper under the container, trapping the bat inside. Humane Society

Not all wildlife removal companies are the same. Some have experience with bat removal projects, and are familiar with the proper methods for bat exclusion. But others use incorrect techniques, such as bat traps, summer exclusions, or worse, fumigants.
Do bats eat when they hibernate? Hibernate or Migrate. Bats use a lot of energy flying around and must consume a lot of food, such as insects, to fuel their daily activities. When cold weather drives insects away, bats must choose to hunker down and hibernate or migrate to warmer areas with more abundant food supply. National Park Service
