Does vinegar kill Cockroaches?

Thankfully, our home contains a number of products, including baking soda and bleach, that are known to kill roaches somewhat. However, these products are not ideal for a quick and effective solution against an infestation. Similarly, we may think does vinegar kill roaches?

Vinegar alone does not kill but can repel roaches slightly. However, when mixed with soap or shampoo, vinegar can kill roaches. This is because when shampoo is added to vinegar, it lowers its surface tension and allows the solution to coagulate the respiratory openings of the roach.

Unlike humans, insects, including roaches, respire through the respiratory openings called spiracles located on each body segment. The spiracles do not allow a liquid with higher surface tension to enter them. This prevents the vinegar from entering into spiracles to kill roaches effectively.

Vinegar alone does not kill roaches

A distilled vinegar has a pH of around 2.5, making it strong enough to clean surfaces. White vinegar is the diluted form that we usually keep in our kitchens.

The strong smell keeps the roaches away until vinegar loses its smell. However, vinegar is not a strong acid; it does not kill roaches on contact unless it reaches the respiratory opening.

Therefore, vinegar alone is not effective at killing roaches. It’s better to use roach baits like combat roach trappers. Cockroach chalk is also a type of bait used to kill roaches.

Can vinegar drive away cockroaches?

Cockroaches have a strong sense of smell to attract each other into mating (Reference). This feature comes in handy for repelling roaches. Several natural roach repellents can very effectively keep roaches at bay.

Thanks to the acetic acid, vinegar has a strong, pungent odor. This strong, pungent odor is known to drive away roaches effectively. However, it has two drawbacks,

  1. The smell will also drive you crazy and can give you sneeze
  2. The smell fades away once the vinegar dries

Therefore, I do not recommend vinegar for repelling roaches.

How to kill roaches with vinegar?

It’s midnight, and you can’t sleep with a cockroach in your room thinking about how to kill this moth** fuc*** with no insecticide sprays and traps at hand. Then you immediately think of vinegar sitting in your kitchen, lets try this. But to your surprise, it didn’t work.

Vinegar does not kill roaches alone. So let me tell you a hack about killing roaches with vinegar.

Step 1: Take one cup of white vinegar

The stronger the vinegar, the quickly it kills the roaches. Therefore, if available, use distilled vinegar. However, you can use any type of vinegar available on hand. Take the amount of vinegar needed, at least one cup.

Step 2: Pour down it into a spray Bottle

The spray bottle will help you reach the solution to your target. However, if you do not have a spray bottle, you can splash the solution.

Step 3: Add a few drops of shampoo

The next step is to add a few drops of shampoo. For example, one cup of vinegar needs ten drops of shampoo. Again, mix well before using it.

Step 4: Spray it directly on the roaches

Vinegar with added shampoo will only kill roaches if you directly apply it over the roaches. Do not expect it to work like insecticide spray.

Step 5: Wait for the results

The cockroach can live without oxygen for a few hours. Therefore you have to wait patiently before seeing the results.


The market is flooded with efficient and economic roach-killing products. Unfortunately, vinegar is smelly, difficult to use, and not entirely effective at killing roaches if used alone. However, in case of emergency, you can use vinegar mixed with shampoo or soap to kill roaches when you don’t have anything at hand.
