How do bats get into my attic?
Six millimeters. Tiny, isn't it? And yet, that's enough space to let a bat in the attic. Although, it's common to have a bat in your attic, these spaces can be anywhere in your home. Here are some entry points that bats particularly appreciate.
The intersections between the roof and the soffits
The place where the roof and soffits meet allows easy access for a bat in your attic. Bats can take advantage of the space and sneak into the attic.
Electrical conduits are spaces that allow electrical wires and cables to enter a house to supply electricity. Bats can sneak into your house, especially if your house is not connected to an underground power grid.
The holes around the chimney and windows
A hole as small as 6 mm in diameter in size allows enough space to let a bat into the attic.
The different types of vents (roof vents, attic vents, dryer vents, wall vents, plumbing vents)
Vents are holes or openings made on the roof or walls to evacuate moisture and heat (attic, roof, dryer vents) or to ensure air circulation (wall vents, ventilation pipes for plumbing). If not adequately protected, these openings allow space for a bat in the attic. Bats can take advantage of them to sneak into the attic. Since bats are nocturnal animals, the best time to observe them is at nightfall, when they go out hunting, and at dawn, when they go back to sleep. A one-hour observation at either of these times is sufficient to determine the spot that allows bats in your attic.
