Can You Fog Bats Out of Your Attic? A Comprehensive Guide
No, you cannot and should not fog bats out of your attic. Fogging is ineffective, inhumane, and often illegal, making professional bat exclusion the only responsible and effective solution.
Understanding the Ineffectiveness of Fogging
The question “Can you fog bats out of your attic?” often arises from a desire for a quick and easy solution to a bat infestation. Unfortunately, fogging is far from that. Bats are highly mobile and will simply move to another part of the attic or building to avoid the fog. They are adept at finding shelter in crevices and are not easily deterred by repellents, especially not for extended periods.
- Fogging agents, even those marketed as bat repellents, offer only temporary relief at best.
- Bats quickly become accustomed to the smell or taste and return to their roosting sites.
- Fogging can trap bats inside, leading to starvation and the potential spread of disease when they eventually die.
The Inhumanity of Fogging
Beyond its ineffectiveness, fogging is an incredibly cruel method for dealing with bats. Bats are essential to the ecosystem, providing valuable insect control. Eliminating them through inhumane means is both unethical and ecologically damaging.
- Fogging can harm or kill bats, especially young ones who are unable to fly and escape.
- Even if the fogging agent doesn’t directly kill them, it can stress them, making them more susceptible to disease and starvation.
- The lingering effects of the fogging agent can contaminate their roosting site, making it unsuitable for future generations.
Legality Issues Surrounding Fogging
In many states and provinces, fogging bats out of your attic is illegal. Bats are often protected under state and federal laws, and harming or killing them can result in significant fines and penalties. Even attempting to repel them during certain times of the year (like the birthing season) is often prohibited. Always check your local regulations before taking any action. This information is critical when asking yourself, “Can you fog bats out of your attic?“
- Most states have laws protecting bats due to their ecological importance.
- Disturbing bat colonies during maternity season is almost always illegal.
- Professionals are trained to follow ethical and legal guidelines for bat removal.
The Correct Approach: Bat Exclusion
The only truly effective and humane way to remove bats from your attic is through a process called bat exclusion. This involves identifying all entry points, sealing them off, and installing one-way devices (usually called bat excluders) that allow the bats to exit but prevent them from re-entering.
The Bat Exclusion Process:
- Inspection: A thorough inspection of the attic and surrounding area to identify all bat entry points.
- Sealing: Sealing all entry points except for a few key exits, using materials that bats cannot chew through (e.g., steel mesh, caulk).
- Excluder Installation: Installing one-way bat excluder devices over the remaining entry points. These devices allow bats to fly out at night but prevent them from flying back in.
- Monitoring: Monitoring the exclusion sites to ensure that all bats have left and that no new entry points have been created.
- Final Sealing: Once all bats are gone, sealing the remaining entry points permanently.
- Clean-up: Cleaning and disinfecting the attic to remove bat droppings (guano) and prevent the spread of disease.
Materials Commonly Used for Bat Exclusion:
- Steel Mesh: Used to cover large openings and prevent bats from chewing through.
- Caulk: Used to seal small cracks and crevices.
- Expanding Foam: Used to fill larger gaps.
- Bat Excluders: One-way devices that allow bats to exit but not re-enter.
Why Hire a Professional?
While DIY bat exclusion is possible, it’s highly recommended to hire a qualified wildlife removal specialist. Professionals have the knowledge, experience, and equipment necessary to safely and effectively remove bats from your attic without harming them or violating any laws.
- Experience: Professionals understand bat behavior and can identify all entry points.
- Equipment: Professionals have the specialized equipment needed to seal entry points and install excluders safely.
- Safety: Professionals are trained to handle bats safely and avoid exposure to diseases.
- Legality: Professionals are aware of local laws and regulations and can ensure that the exclusion is done legally.
Common Mistakes to Avoid
Attempting to fog bats out of your attic is only one of many common mistakes that homeowners make when dealing with bat infestations. Here are some other errors to avoid:
- Sealing bats inside: This is cruel and can lead to the death of the bats, creating a foul odor and potentially attracting other pests.
- Handling bats directly: Bats can carry rabies and other diseases, so never handle them without proper protective gear.
- Using poisons: Poisons are inhumane and can also pose a risk to other animals and humans.
- Ignoring the problem: Bat infestations can worsen over time, so it’s important to address them promptly.

Frequently Asked Questions
Will mothballs get rid of bats in my attic?
No, mothballs are generally ineffective at repelling bats and should not be used. While the strong odor might deter some bats temporarily, they will likely return once the smell dissipates. More importantly, mothballs are a hazardous material and can pose a health risk to humans and pets. The vapor is also carcinogenic.
How do I know if I have bats in my attic?
Common signs of a bat infestation include: Droppings (guano) on the attic floor or around the exterior of the house, stains around entry points, scratching or squeaking noises at night, and a musky odor emanating from the attic. If you notice these signs, it’s best to contact a professional for an inspection.
What diseases can bats carry?
Bats can carry a number of diseases, including rabies, histoplasmosis, and bat bugs (similar to bed bugs). While the risk of contracting rabies from a bat is low, it’s important to avoid direct contact with bats and to seek medical attention if you are bitten or scratched. Histoplasmosis is a respiratory infection caused by inhaling fungal spores found in bat droppings.
Is it safe to clean up bat droppings myself?
Cleaning up bat droppings can be hazardous due to the risk of histoplasmosis. It’s best to hire a professional with the proper equipment and training to clean and disinfect the attic. If you must clean it yourself, wear a respirator, gloves, and protective clothing. Wet down the droppings with water to reduce the risk of inhaling dust.
What is bat guano, and why is it a problem?
Bat guano is bat feces, and it can be a problem for several reasons. First, it can cause a foul odor. Second, it can harbor histoplasmosis spores. Third, it can attract other pests, such as insects. Finally, it can damage insulation and other building materials.
How much does bat exclusion cost?
The cost of bat exclusion can vary depending on the size and complexity of the infestation, the size of the building, and the location. Generally, you can expect to pay anywhere from several hundred to several thousand dollars. However, this is a worthwhile investment to ensure that the bats are removed safely and humanely and that they don’t return.
When is the best time of year to exclude bats?
The best time of year to exclude bats is typically in the spring or fall, when bats are not hibernating or raising their young. It’s crucial to avoid excluding bats during the maternity season (typically late spring and summer) to avoid trapping young bats inside. This question is critical for understanding, “Can you fog bats out of your attic?” (or, better, exclude them!).
What happens to the bats after they are excluded?
The bats will simply fly away to find a new roosting site. This is why it’s important to exclude them humanely and to avoid harming them in any way. They will find other natural habitats to reside in.
How can I prevent bats from returning to my attic?
Once the bats have been excluded, it’s important to seal all entry points to prevent them from returning. This includes sealing cracks and crevices, repairing damaged screens, and installing chimney caps.
Can I use ultrasonic devices to repel bats?
There is limited evidence to support the effectiveness of ultrasonic devices in repelling bats. While some studies have shown that these devices can deter bats in controlled environments, their effectiveness in real-world situations is questionable. It’s best to rely on proven methods such as bat exclusion.
What is a bat house, and should I install one?
A bat house is a man-made structure designed to provide bats with a safe and suitable roosting site. Installing a bat house can be a good way to attract bats to your property and provide them with an alternative roosting location after they have been excluded from your attic.
Can you fog bats out of your attic? – Seriously, don’t!
To reiterate, no, you cannot and should not fog bats out of your attic. It is an ineffective, inhumane, and often illegal method. The only responsible and effective solution is professional bat exclusion, ensuring the safe and legal removal of bats from your property.
