Bats have long been known to be beneficial because they eat insects. However, they can become a pest when they move into attics, barns and soffit areas of our homes. This article will detail different problems bats create when they roost in or on our buildings and then we will explain the methods of control available to stop these problems.
There are many species of bats throughout the world. In fact, bats comprise the largest segment of mammals in the world. It is estimated that over 25% of the worlds mammals are bats. As man infringes upon their natural habitats, bats get displaced and sometimes move into our homes and other buildings.
The most common entry point for bats in the home is through the gable or attic vents which can be found on most houses. This vent allows hot air to exit the attic and most attics have these vents on either side of the home. Initially, bats will hang from the screening which is behind the louvers.
The screening provides a secure hanging place and the louvers offer shelter. Over time, the screening will break down and bats will quickly move inside where roost sights abound. Once inside, the bats will hang from the rafters and ceiling boards. Their droppings will begin to accumulate posing a health hazard and making a mess. These droppings have been found to contain many contaminants and should not be allowed to accumulate in the home. Bat guano and urine has a strong pungent odor as well and will creep into the living area in a short period of time. Many times their droppings and urine fall into a remote wall space and can remain undetected. Other times it quickly stains ceilings in living areas giving the residents tell tale evidence that something needs to be done.
