Bats are fascinating and important creatures that play a vital role in Australia’s ecosystem. However, for some people, having bats roosting in their homes or gardens can be a problem. Bats can cause damage to property and pose health risks to humans, especially if they carry diseases such as Australian bat lyssavirus. Therefore, it’s important to find ways to deter bats from roosting in undesirable areas.

There are several bat deterrent solutions that are commonly used in Australia. Here are some of the most effective ones:


Bat boxes are specially designed structures that provide a safe and comfortable roosting place for bats. By installing bat boxes in your garden or on your property, you can provide an alternative roosting place for bats, which can help to deter them from roosting in undesirable areas.

Bat boxes should be installed in a location that is sheltered from the elements and provides easy access for bats. They should also be placed high enough to avoid predators but low enough to allow bats to easily enter and exit the box. Bat boxes should be regularly inspected to ensure they are clean and free from parasites.


Bird netting is a common bat deterrent used across Australia. This prevents bats from roosting in specific areas, and can be used to cover trees, buildings, or other areas where bats are roosting. The netting is made from a lightweight material that is easy to install and remove.

Bird netting works by creating a physical barrier that prevents bats from accessing their roosting sites. It’s important to ensure that the netting is securely fastened and that there are no gaps or holes that bats can squeeze through.


Bats are highly sensitive to sound, and certain noises can be used to deter them from roosting in specific areas. There are several noise deterrents that can be used, including ultrasonic devices, loudspeakers, and radios.

Ultrasonic devices emit high-frequency sounds that are unpleasant for bats, while loudspeakers and radios can be used to play loud noises that are also unpleasant for bats. These noises can be used to disrupt bat activity and encourage them to move to a new roosting site.


Bats are nocturnal creatures and are sensitive to light. By installing bright lights in areas where bats are roosting, you can make the area less attractive to them. Bats prefer dark, quiet areas, so by illuminating the area, you can create an environment that is less appealing to them.

It’s important to ensure that the lighting is not too bright and does not disturb other wildlife or cause light pollution. Motion-activated lighting is an effective bat deterrent tactic used across Australia, preferred as it doesn’t cause unnecessary disturbance.


Bats are attracted to areas where there is a good supply of food, such as fruit trees or gardens. By removing food sources, you can make the area less attractive to bats. This can be achieved by removing fruit trees or covering them with netting to prevent bats from accessing the fruit. In conclusion, there are several effective bat deterrent solutions that can be used in Australia. By using a combination of these methods, you can create an environment that is less appealing to bats and encourage them to roost in alternative locations. It’s important to remember that bats are protected in Australia, and it’s illegal to harm or kill them. Therefore, it’s important to use humane and non-lethal methods to deter bats from roosting in undesirable areas.
