Imagine you are tucked into bed, ready for a restful night’s sleep when suddenly you hear the eerie high-pitched squeaking and flapping of wings – an uninvited guest has made your home theirs. Yes, we’re talking about bats! While they might be fascinating creatures of the night, finding them in your house can be a bit disconcerting, to say the least. Welcome to our comprehensive guide on dealing with bats in your home. We’ll arm you with effective strategies to handle these unexpected nocturnal visitors, ensuring both their safety and yours. From understanding why they choose to roost in human dwellings to humane removal techniques, we’ve got you covered. So, brace yourself as we take a deep dive into the world of bats, turning your fright into knowledge and your anxiety into action.

Understanding Bat Behavior

Bats are intriguing creatures that lead a nocturnal lifestyle, meaning they are most active at night. They have excellent navigational skills which they owe to their exceptional hearing and ability to echolocate. Echolocation allows them to determine their surroundings and locate their prey in the dark. This is why you’ll often hear the high-pitched squeak that is characteristic of bats when they are around. Their diet primarily consists of insects, which they hunt in the dark.

Despite their somewhat fearsome reputation, bats are generally not aggressive creatures. They are more likely to be scared of humans than the other way around. However, when cornered or feeling threatened, they may bite in self-defense. This is why it’s important to understand their behavior and handle them correctly when they venture into your home.

What attracts bats to your home? Bats look for warm, safe places to roost and your attic or chimney provides just such a haven. They prefer dark, quiet, and secluded places where they can rest during the day without being disturbed. The gaps and openings around your house, such as vents, loose tiles, and cracks, are potential entry points for these uninvited guests.

Dangers of Bats in Your Home

Having bats in your home is not just a nuisance, but also a potential health risk. Bats are known to carry diseases, notably rabies, which can be fatal to humans if not treated promptly. Bat droppings, also known as guano, can harbor a fungus that causes Histoplasmosis, a lung disease. Thus, it’s essential to handle bat infestations promptly and appropriately to minimize these risks.

Additionally, the accumulation of bat guano can lead to structural damage in your house. The droppings can corrode wood and metal, and the strong odor can permeate your home, creating an unpleasant living environment. Furthermore, a large colony of bats can create a lot of noise, especially when they are active during the night, causing sleep disturbances.

Bats are protected species in many regions, and it’s illegal to kill or harm them. Therefore, it’s crucial to approach bat removal in a way that safeguards both the bats and the inhabitants of the house.

Signs of Bat Infestation

Identifying a bat infestation early can prevent potential health risks and structural damage to your home. Look out for these signs: Irregular noises, especially at night, such as squeaking or scratching sounds, could indicate the presence of bats. These sounds are often heard from the attic, walls, or chimney.

Another tell-tale sign of a bat infestation is the presence of bat guano. Bat droppings are small, about the size of a grain of rice, and usually piled up underneath the area where they roost. They may also leave traces of guano around the entry points to your house.

You might also notice dark, greasy marks around small holes or cracks in your house. These are the oils from the bat’s fur, left behind as they squeeze through these openings. If you see bats flying around your property at dusk, this could also be an indication that they are roosting in your home.

Steps to Take When You Discover Bats in Your Home

Upon discovering bats in your home, it’s essential not to panic. Remember, bats are more afraid of you than you are of them. The first thing you should do is isolate the area where the bats are, if possible, and keep children and pets away.

Avoid handling bats with bare hands as they could bite or scratch in self-defense. If a bat is flying around in your living space, try opening windows or doors to give it a way out. Turn off the lights and reduce noise to make the environment less stressful for the bat.

If the bat does not leave on its own, you may need to capture it carefully using a thick towel or wearing protective gloves. Once captured, release it outside, away from your home. If you suspect that the bat has bitten or scratched anyone in your household, capture it without touching it (using a container) and call your local health department for advice, as it may need to be tested for rabies.

Bat Removal Techniques

The best way to rid your home of bats is through a process known as exclusion. This involves identifying the bats’ entry and exit points and installing one-way devices that allow the bats to leave but not re-enter. The timing for this is crucial, as you want to avoid separating mother bats from their pups. The exclusion process should not be done during the bats’ breeding season.

Sealing off all potential entry points, except the main ones where the exclusion devices are installed, is vital. This prevents the bats from finding another way in. After all the bats have been excluded, the remaining entry points should be sealed.

Exclusion is a process that requires precision and a good understanding of bat behavior. Improper exclusion can lead to bats being trapped inside the house, which is not only inhumane but can also lead to more damage as the trapped bats try to find another way out.

Professional Bat Removal Services

While it’s possible to perform bat exclusion yourself, it’s often best to hire professional bat removal services. Professionals have the training and equipment to handle bat infestations safely and humanely. They can also thoroughly clean and decontaminate the affected area, removing guano and sterilizing the space to eliminate any health risks.

Professional bat removal services are also aware of the legalities surrounding bat removal. Different regions have different laws protecting bats, and professionals can ensure that the removal process is compliant with these laws.

It’s important to choose a reputable bat removal service that practices humane removal methods. Avoid companies that advocate for lethal methods or the use of repellents, as these are not only inhumane but often ineffective and potentially harmful to both the bats and the environment.

Preventing Future Bat Infestations

Once you’ve dealt with a bat infestation, taking steps to prevent future infestations is crucial. This involves sealing all potential entry points, including cracks, gaps, and holes in the walls, roof, and foundation of your house. Regular inspections can help identify any new potential entry points.

Maintaining your home also plays a role in bat prevention. Loose tiles, broken windows, or a deteriorating roof can create openings for bats. Keeping your home in good repair can prevent this.

Installing bat houses in your yard can provide an alternative roosting spot for the bats, diverting them from your home. Bat houses are specially designed structures that mimic the conditions that bats look for when choosing a roosting spot.

The Role of Bats in the Ecosystem

While bats can be a nuisance when they roost in our homes, they play a crucial role in the ecosystem. Bats are excellent pest controllers, consuming large quantities of insects every night. Some species also pollinate plants and spread seeds, contributing to biodiversity.

Bats are an integral part of our ecosystem, and their decline can have far-reaching effects. Therefore, it’s essential to handle bat removal in a way that protects these fascinating creatures. While it’s crucial to ensure our homes are safe and bat-free, we must also respect bats and the vital role they play in our environment.


Dealing with bats in your home can be a daunting task. However, with the right knowledge and approach, it’s possible to handle these uninvited guests in a way that ensures both your safety and theirs. It’s important to remember that bats are generally not harmful unless threatened. If handled properly, they can coexist with us without posing a threat.

The key is to understand their behavior, recognize the signs of infestation, and take appropriate action. Whether you choose to tackle the problem yourself or hire wildlife professionals, the goal should be the same – humane, effective removal and prevention of future infestations. With a bit of effort, you can ensure your home remains a bat-free zone while still appreciating these intriguing creatures of the night from a distance.
