Bats inside a house with stable access to a local source of food and water will live their full life expectancy. If you see a bat in your closet or living room, it probably got there by accident. Bats can find openings in the attic that they think lead outside, only to find themselves lost in their room and unable to find their way back. Unfortunately, seeing a single bat generally means that there are likely to be many more hidden in the attic.
Bats are social animals and hundreds of bats can live in a single colony. Your penthouse may not be used to house such a large colony, but it's not unusual to find a dozen or more in a single house in North America. If you haven't seen the plague with your own eyes, here's more information on how to tell if the animal in the attic is a bat or something else. Penthouses offer better shelter than anywhere else, so if a bat can get inside, it's likely they'll start sleeping there.
If the chimney has cracks or holes that lead to the attic, bats can use it as a path to enter your home with ease. Other diseases, such as the rabies transmitted by bats, may remain alive temporarily after the death of their host. If you want to get rid of bats on your own without the help of professionals, there are a few things to consider. Because bats are capable of transmitting rabies, many people wonder if seeing a bat outside during the day is an indication that they are angry.
In many cases, bats may not leave home as quickly as you'd like, or your efforts to get rid of them may not work. You'll see bat droppings build up under beams and other places where bats sleep, often in a straight line. The coat of a large brown bat ranges from light brown to dark brown, with black on its snout, ears and wings. According to the Agricultural Experiment Station in Rutgers, New Jersey, bats are incredibly misunderstood.
Unless you've experienced bat nesting in your home, it's probably something that isn't in the foreground of your mind. However, there are other bat species that have a more varied diet, since they survive on nectar, fruit and pollen. However, many different bat species have different needs, and some hibernate or migrate during specific times of the year. Finally, having bats on your property may be worse for you than insect pests, since bats harbor diseases such as rabies and histoplasmosis, and their guano can cause allergy problems.
These places where moisture can build up also provide insect pests with a place to reproduce and also provide food for bats.
