Vinegar isn’t powerful enough to kill roaches when it is sprayed on them, so it’s better to kill roaches with a fly swatter or a pesticide spray. To eliminate a roach infestation, contact a professional exterminator or use a combination of insect growth regulator (IGR), roach spray, roach foggers, and diatomaceous earth to kill these pests yourself.

Why Doesn’t Vinegar Kill Roaches?
Vinegar is not a strong enough acid to kill roaches on contact. It also does not clog their respiratory system and cause the roaches to suffocate. So, a roach sprayed with vinegar may react by running away, but it won’t be killed.
- Vinegar does not contain strong acids or chemicals that kill roaches instantly.
- Mixing vinegar with soap or other compounds does not create a homemade roach killer.
- Roach infestations require strong measures to kill roaches and prevent them from reproducing.
Some claim that a mixture of white vinegar and dish soap in a spray bottle will kill roaches, but this is also ineffective. Roaches are extremely hardy insects. Although you can use vinegar to kill silverfish and other fragile insects, you need to use something far more powerful to destroy a roach invasion.
Does Vinegar Kill Roach Eggs?
Roach eggs will survive, even if they are soaked in vinegar. So, it’s best to use vinegar as a home cleaning product instead of a roach killer. Roach eggs sprayed with vinegar will still hatch in almost every case.
- Vinegar is ineffective at killing roach eggs.
- Roach eggs are often hidden inside walls, so it can be hard to find them anyway.
- This Insect Growth Regulator (IGR) prevents roaches from laying eggs in your home.
In addition to surviving vinegar sprays, roach eggs can be very hard to find. Roaches tend to lay their eggs in hidden places—such as inside walls—so you’ll have a very hard time finding roach eggs to spray them all. That’s why systemic roach killers are the best choice for ridding your home of roach infestation.
Does Vinegar Make Roaches Go Away?
Vinegar does not act as a roach repellent. Roaches are so drawn to the scent of food or dirty dishes that they won’t let anything stand in their way. Spraying surfaces with vinegar won’t stop roaches from scurrying across them. So, even if you douse your home with vinegar, the roaches won’t flee.
- Vinegar will not cause roaches to avoid an area or leave your home.
- Roaches will ignore vinegar if there is a food source nearby.
- Vinegar can be used to clean surfaces and kill salmonella bacteria carried by roaches.
The good news is that using vinegar to clean your countertops and other non-porous surfaces can kill the salmonella bacteria carried by roaches. So, even though vinegar won’t keep roaches away, it can be useful to prevent you from suffering a roach-caused illness.
What Kills Cockroaches Instantly?
In order to kill roaches right away, use a commercial roach-killing spray. These sprays contain pesticides, but they are truly the best way to kill roaches in seconds. Spray the roach with a roach killer spray and wait for it to die. Then, dispose of the roach and thoroughly clean the surface where the roach was sprayed. If you prefer not to use pesticides, use a fly swatter, shoe, or another object to smash the roach to kill it. This is far more effective than using vinegar.
- This pesticide spray kills roaches on contact.
- You can kill roaches instantly with a fly swatter or similar tool.
- A licensed exterminator will be able to use the most powerful methods for killing roaches in your home.
- You can use this roach fogger in your home, but you must turn off the electricity to your home and leave the premises for several hours.
If your home is infested with roaches, consider contacting a professional exterminator. They can use powerful methods not available to you. However, you can use a roach fogger (also known as a roach bomb) in your home to kill roaches. Just make sure to follow extreme safety precautions when using a roach fogger. This includes turning off the power to your home and vacating the entire home for several hours.
What is the Best Homemade Roach Killer?
The safest and best roach killer to use in your home is food-grade diatomaceous earth. This substance is all-natural and made from the fossils of tiny organisms. It contains no pesticides and is safe for use around humans, pets, and food. To kill roaches, dust countertops, cabinet shelves, and the areas along baseboards with diatomaceous earth. Within 24–48 hours, roaches will begin to die.
- This food-grade diatomaceous earth is the best choice for killing roaches without pesticides.
- Dust diatomaceous earth in your kitchen and along baseboards.
- Diatomaceous earth contains no pesticides, so it’s safe for use throughout your home.
- The tiny particles of diatomaceous earth dehydrate and kill roaches as they walk through the powder.
- Diatomaceous earth will begin killing roaches within 24–48 hours after you spread it in your home.
Diatomaceous earth works by cutting and scraping the exoskeleton of roaches and other insects. Then, it dehydrates and kills them. Whatever other methods you’re using to kill roaches, it’s worth dusting diatomaceous earth throughout your house. You’ll kill more roaches and won’t be introducing any more chemicals to your home. Other home remedies, such as boric acid, can be harmful to humans and pets, and may take weeks to start killing roaches.
Is Vinegar Good For Killing Roaches?
If you are thinking of using vinegar to kill roaches, keep these facts in mind:
- Vinegar spray will not kill roaches.
- Roach eggs are not harmed by vinegar.
- Vinegar will not repel roaches.
- Pesticide sprays and fly swatters are far more effective for killing roaches instantly.
- Use Insect Growth Regulator (IGR) to stop roaches from laying eggs, or contact a professional exterminator to end your roach infestation.
- Diatomaceous earth powder is an effective home remedy for killing roaches, but it requires the roaches to walk through the powder before it begins killing them.
Since using vinegar won’t result in dead roaches, don’t waste your time with the substance. Commercial roach traps, baits, and gels are much more effective. Roaches of all kinds are extremely tough. Although some insects can be harmed by vinegar, roaches will easily survive vinegar exposure.
