Bats are tiny winged mammals with the ability to squeeze through very tiny spaces. These animals are in perpetual search of the perfect roosting places which should be close enough to food and water and at the same time warm and dark and away from loud noises.
Houses with barrel tile roofs have a higher probability of becoming homes for bats because the ridges of this roof provide a good hiding spot for bats. And if there is a small tear or opening in the tar-paper beneath the tiles, these small mammals can squeeze through them and get into your roof and find their way to your attic.
A bat colony in a home can be a great source of stress for the occupants, these animals may seem harmless, but they bring with them a number of diseases that stay hidden in their droppings; called guano. Bat infestations also attract other animals and insects such as rodents and bat bugs. Therefore, any sign that you have bats living in your home shouldn’t be overlooked because the longer they stay, the harder it becomes to evict them.
Evicting bats from a building involves a few steps which are to be done very carefully and as thoroughly as possible. Although this is a job that is best left to the professionals, anyone with good climbing skills, the ability to squeeze into certain small spaces, and can be very observant will successfully get rid of bats following the right steps and procedures.
The ridges on barrel tile roofs are unquestionably very beautiful, but this is also what makes evicting bats from this type of roof very difficult. Each ridge has a small space where bats can hide and even the smallest tear in the tar-paper beneath will be an entrance point through which these tiny animals can get into your house and establish themselves.
Some bat species are very tiny and can squeeze themselves through holes that are as small as 0.5 inches wide. A thorough examination of the roof will require that you carefully examine every ridge for signs of bat movement.
Look for small tears and greasy stains which is an indication that bats have been there. Then proceed to meticulously seal any holes you find with a good sealant, but leave one or two holes unsealed. This can be a tremendously difficult job for one person because every single ridge has to be carefully inspected, it’s a job best left to the experts.
The best way to safely evict bats, which is also the legal and most humane method, is to perform a live bat exclusion using an exclusion device. A one-way exclusion device will ensure the animals safely leave the house but will be unable to find their way back in. Now, you will have to carefully install a one-way valve in the hole(s) you left unsealed.
The idea is to provide the bats a safe passage out of the building while giving them no entry back into the building. A one-way valve is something that requires very careful handling because if installed incorrectly a bat may get trapped in it and prevent other bats from leaving through the hole, making the operation ineffective.
When you are sure that all the bats have left the building via the one-way exclusion device you installed, now it’s time to move to uninstall the device and carefully seal up the hole(s). It can take a few days and nights for the bats to leave completely, and ensure you actually go in to see for yourself that no bats are left in the building before proceeding to completely seal the building.
If you notice that the bats are roosting beneath the ridges and not actually in the building, then you will have to wait for them to leave before you can move in to seal the ridges. The bats will most likely get in during the winter season when the weather becomes unfavorable. This may require that you invite bat control experts to your home for thorough removal of any bat remains.
You should know that bats carry a number of diseases that can affect humans and even when they are gone, their droppings (guano) contain a fungus that causes a potentially fatal respiratory disease — Histoplasmosis — in humans. To ensure your safety and that of your entire household, call bat removal experts.
