Will Brake Cleaner Kill Spiders?

Brake cleaner can kill spiders. However, it is not an effective long-term solution and can be harmful to humans and the environment.

Brake cleaner is a popular choice for killing spiders because it is a powerful solvent that can dissolve the spider’s exoskeleton and cause it to die. However, this method is not recommended as a long-term solution because spiders can easily return to the same area. Furthermore, brake cleaner contains harmful chemicals that can be dangerous to humans and the environment if not used properly. It is important to use alternative methods for spider control such as vacuuming, sealing entry points, and using natural repellents. Overall, it is best to avoid using brake cleaner as a spider killer.

What Is Brake Cleaner?

Brake cleaner is a solvent that is used to dissolve contaminants and debris from various surfaces, including brake components. It is usually made up of acetone, toluene, and methanol, and can work wonders in removing oil, grease, and grime from different surfaces.

Brake cleaner is commonly used in automotive repair shops and factories for cleaning brake parts, engine parts, and other machine parts. However, when using brake cleaner, there are some safety measures that should be taken to prevent injury and damage to the environment.

One should avoid using it near an open flame, in an enclosed space, or without adequate ventilation. Brake cleaner is a versatile solvent that can be effective in removing spider webs and killing spiders, but it should be used cautiously.

Why Do People Suggest Using Brake Cleaner To Kill Spiders?

Brake cleaner is a popular solution for killing spiders. The theory behind this method is that the chemicals in brake cleaner are toxic enough to kill spiders on contact. While it may be effective in killing spiders, it doesn’t repel or prevent spiders from returning.

Additionally, brake cleaner can be harmful to humans and pets if not used carefully. It’s important to note that brake cleaner should only be used as a last resort and in well-ventilated areas. Using safer spider control methods such as vacuuming or placing citronella plants around your home may be a better long-term solution.

Always practice caution and read instructions before using any chemical products in your home.

What Are The Potential Risks Associated With Using Brake Cleaner To Kill Spiders?

Using brake cleaner to kill spiders can have potential health risks to both humans and pets. Inhalation of the chemicals present in the cleaner can cause respiratory problems and irritation to the eyes and skin. Pets can also suffer from similar effects if exposed to the chemicals.

Moreover, using brake cleaner can also have environmental risks. Disposing of the canisters can potentially pollute the environment, causing harm to plants and animals. It is advisable to use eco-friendly spider repellents, which are safe for humans and pets. It is important to always read the label carefully and follow the instructions to minimize any potential risks associated with using brake cleaner.

What Are Some Alternative Spider Control Methods?

Brake cleaner can work on spiders, but it’s not a recommended spider control method. Natural remedies might prove more helpful. For example, essential oil sprays made with peppermint, lavender, and tea tree oil can be an effective repellent. Chemical sprays that contain bifenthrin or permethrin can also be an option.

Prevention measures like minimizing clutter, vacuuming regularly and sealing cracks and crevices can significantly reduce spider infestations. While brake cleaner may kill spiders, there are more natural and reliable ways to control spider populations that are worth considering. These remedies are much safer for people and environmentally friendly too.


After researching and analyzing the ingredients of brake cleaners, it is safe to say that they can be effective in killing spiders. However, caution must always be exercised when using any form of pesticide or insecticide. Brake cleaners may contain harmful chemicals that can be risky for human health and the environment.

It is advisable to read and follow the instructions carefully before using brake cleaners. Furthermore, it is essential to remember that brake cleaners are designed to clean and degrease, not for eliminating spiders. Therefore, it is always best to consult with pest control professionals for a safe and effective solution to spider infestations.

While brake cleaners may effectively kill spiders, they should be used with caution and preferably as a last resort after exploring other available options.
