Why do bats enter houses?

Female bats like dark, warm places, especially to give birth to their young. The attics of our houses are therefore places that seem quite suitable for this purpose. In addition, females are endowed with a strong homing instinct, which means that a colony persists in returning to nest in the same place over the years.


How do bats get into houses?

Bats have many favourite entry points. This may be the cornice on the roof or cracks or fissures on and around the roof. The other possibility is through the different types of vents (roof, attic, wall, plumbing). Vents are holes or openings made on the roof or walls to evacuate moisture and heat (attic or roof vents) or to ensure air circulation (wall vents, ventilation pipes for plumbing).

Some bat species are so small that an opening of 6 mm in diameter is sufficient for them to enter.

Are bats dangerous?

In general, no. In fact, bats are very useful, as they rid us of many insect pests, such as mosquitoes. A bat can catch nearly 600 mosquitoes in an hour!

However, bats are also vectors of disease, such as rabies and histoplasmosis. If you are bitten or scratched by a bat, see a doctor immediately for a rabies vaccine. Histoplasmosis is a disease that is transmitted by breathing bat dung dust.

If you find a bat in a room, consult your doctor even if no bite or scratch is visible. Some bats' teeth are so thin that a bite could easily go unnoticed.

Given these health risks, professional help is strongly recommended. A bat has entered your home and you wonder how to get rid of it? Contact us today!
