If you find one bat in your house there is a good chance that you have more.
Do i have bats in my attic.
Seeing swarms of bats continually hovering around your home every evening is one of the colossal signs bats live in your attic.
They can enter a house through a hole as small as 5 8 inch often near chimney flashing and under eaves.
Colonies of bats prefer quiet cave like spaces to roost reproduce and raise their young.
They sometimes travel through walls or pipes looking for spaces to live.
Home owners with bats in their attics tend to see anywhere from 1 or 2 bats flying back and forth to swarms of them flying in and out of their attic all night long.
Some bats will follow the warm air and crawl inside the vent often making it all the way to the attic.
If it gets colder than that the bats in the attic will migrate out allowing you to seal up cracks and other entry points once they leave for the season.
Bats will hibernate in the winter if the temperature stays at around 35 to 40 f.
If you live in an area with mild temperatures throughout the year the bats will stay year round.
Signs of bats in the attic.
Bats can also get into attics through damaged roofs.
Rotten shingles gaps in the framing or space between the eaves and the walls can lead to bats finding their way inside.
They don t like the cold and your attic is nice and warm.
They re nocturnal so they live their lives in darkness making your attic a prime piece of real estate for bats.
Again a gap can be quite small and bats will still fit through it.
