Is it safe to use brake cleaner as a form of insecticide? What is the best way to kill wasps with items that you have lying around the house?

In this article, we will discuss these subjects to find out will brake cleaner kill wasps?

Will Brake Cleaner Kill Wasps?

Yes. Break cleaner is surprisingly effective against killing wasps and many other insects. You can use brake cleaner because it is filled with toxic chemicals that are not intended for direct contact with our skin or the exoskeletons of insects.

If a wasp’s makes direct contact with brake cleaner, the toxic ingredients will quickly permeate through their pores and cause them to die instantly. Unfortunately, brake cleaner is dangerous to use and will irritate your skin on contact.

Do not inhale it, wear a mask and gloves and make sure that you are making direct contact with the wasps in order to kill them effectively with brake cleaner.

What Are The Risks Of Using Brake Cleaner to Kill Wasps?

Using brake cleaner to kill wasps is not a recommended or safe method. Brake cleaner is a highly flammable and toxic chemical that is specifically designed for cleaning automotive brake systems. It contains hazardous chemicals that can be harmful to humans, animals, and the environment.

Attempting to use brake cleaner as a pesticide or wasp killer can pose several risks, including:

  • Health Hazards: Brake cleaner contains toxic chemicals that can cause skin and respiratory irritation, dizziness, nausea, and other health problems when inhaled or absorbed through the skin.
  • Flammability: Brake cleaner is highly flammable and can easily catch fire. Using it near an open flame or ignition source can lead to accidents and fires.
  • Environmental Impact: Spraying brake cleaner outdoors can contaminate the environment, harming plants, animals, and aquatic life.
  • Legal Consequences: Using chemicals in a manner inconsistent with their intended purpose may violate local regulations and laws.

If you have a wasp problem, it’s safer and more effective to use proper pest control methods and products designed for dealing with stinging insects. Here are some safer alternatives:

  • Commercial Wasp Spray: Use commercially available wasp sprays specifically designed for killing wasps and hornets. Follow the product’s instructions carefully.
  • Professional Pest Control: If you have a severe infestation or if the nest is hard to reach, consider contacting a professional pest control service. They have the expertise and equipment to handle the situation safely.
  • Prevention: Take preventive measures such as sealing entry points, keeping food sources sealed, and maintaining cleanliness to discourage wasps from nesting near your home.

Does WD-40 Kill Wasps?

WD-40 works like many other commercial products that exterminators use to kill wasps. It is essentially a mixed bag of chemicals applied in a can that can be sprayed directly on the nest or the wasps in question.

What will happen is, their mucous membranes, pores and breathing apertures will effectively be clogged and they will die right away.

WD-40 with the only spray can near me when I decided to try it out in my garage. There was a wasp on its own flying near the hood of my car that was parked in the garage.

I picked up a can of WD-40 and sprayed it directly at the wasp. It was dead in its tracks within a matter of seconds.

Will Brake Cleaner Kill Bugs?

Yes. Brake cleaner works as effectively as many other types of bug sprays to kill a whole range of insects including wasps, bees and spiders and more.

It will poison the breathing pores of bugs by entering their exoskeletons and clogging them. It will also evaporate quickly from the surfaces and expel into the air making it dangerous for you to inhale as well.

Always be safe when using brake cleaner to kill bugs. They are more dangerous than insecticides for us to inhale. Every time I use brake cleaner, I wear a mask, but when I use bug spray I tend to just look away and spray willingly.

Remember that bug spray aerosol spreads out the liquid inside it while brake cleaner spray is more direct.


Remember that brake cleaner can also remove paint and discolor the finishes around the exterior of your home. You cannot inhale or get this product into your eyes.

Spray downwind and keep the stream directly at the wasps because it does not spread out the way other insecticides do in aerosol cans.

Foaming sprays and regular insecticides work well to kill wasps, but break cleaners are fantastic at clogging their pores and killing them immediately.
