Does Listerine kill roaches? Yes, it will. Even better you can use Listerine (or other mouthwash) with a bit of washing up liquid that will aid in repelling cockroaches away.
To do this, mix equally water and Listerine and then add a couple of drops of washing up liquid. Next, give it a good shake in the spray bottle and either spray around your home or directly at the roaches.
Can Listerine in Hair Spray Kill Roaches?
Yes, it does and surprisingly fast too. To use, simply put it in a spray bottle and spray it around picnic chairs and tables or around your home to keep bugs and mosquitoes away.
The spray is sticky and once it lands on flying insects, it makes their wings unusable and seals the breathing orifices to suffocate the insects.
Because it is a water-soluble, you can wipe it with ease by using a damp cloth and leave no stain on wallpaper or curtains. I’ve used it on ants, cockroaches, ants, wasps, etc. I simply chase these critters to a window and spray them on the glass pane, then cleanup with a wet paper towel.
Warning: Bear in mind that hair spray is flammable and should never be applied in an area with an open flame.
