How do bats get into my attic?
Six millimeter. Tiny, isn't it? And yet, that's enough space for some bat species to get into your home. These spaces can be anywhere on 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 can be a good place for bats to enter, as they can take advantage of the space created to 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 is enough for some bat species to sneak into a house.
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 these openings are not adequately protected, bats can take advantage of them to sneak into a house. 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 where bats enter and leave your home.
