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.

How Do I Use Brake Cleaner to Kill Wasps?

  • Flies
  • Wasps
  • Bees
  • Mosquitoes 
  • Ants

What Kills Wasps Instantly?

Do you want to kill wasp right away? Using brake cleaner might work well for you, but the majority of DIY recommendations involve using dish soap and water in a spray bottle.

All you have to do is:

  • mix 2 tablespoons of dish soap and fill the rest of the bottle with water.

What you are looking to do is clog the breathing pores of wasps with the dish soap while the water acts as a carrier. This will clog their breathing apertures and cause them to stop breathing.

Brake cleaner uses the same philosophy by applying the toxic chemicals included in each can to cover, fill and clog the pores of wasps in order for them to die immediately.

How is Brake Cleaner a Wasp Killer?

Brake cleaner clogs the pores of wasps and kills them immediately. It can also kill the scent that wasps leave behind in order to find their way back to their nests.

Brake cleaner has a direct stream and doesn’t spread out very wide, therefore you have to aim directly at the wasps in order to kill them.

Spraying it all over the sides of your exterior walls can cause discoloration or remove the paint all together

Where Should I Spray Brake Cleaner?

Do not spray brake cleaner anywhere inside your house or where circulation is poor. Brake cleaner is a ridiculously fast and effective method of killing wasps, but you must use it carefully.

  • Spray brake cleaner directly onto the bodies of wasps in order to kill them immediately.

Aim it directly on the wasps that you see because the spray that comes out of the can is direct. It will not spread out like many aerosol cans.

You can direct it at their nest as well but please cover your skin and do not leave your lungs exposed because the fumes are toxic. Wear a mask and gloves.

What Does WD-40 Do to 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.
