How long can a bat live inside a house? 6 months. Generally, they enter the living quarters through unfinished basements, loose attic hatches, or through unlined cold air returns. It is a rare bat that simply flies through the front door as a random occurrence. Depending on the time of year and the climate, bats can live over 6 months without food and water.
Bats are usually able to exist near human homes without making their presence known. However, with decreasing amounts of habitat available for bats (e.g., trees being cleared), bats may find their way into man-made structures. Bats use existing openings (cracks as small as 1 ΒΌ inch by 3/8 of an inch) to enter buildings or to roost in attics.

Do vampire bats really exist? Yes, but not in most of the United States. Of the three species of vampire bats in North America, only a single specimen has been recorded for the United States in extreme southwest Texas. Vampire bats do not suck blood--they make a small incision with their sharp front teeth and lap up the blood with their tongue.
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
