Cockroaches are difficult and persistent household pests and are capable of reproducing quickly. In some cases, they can be resistant to control measures. How about vinegar for controlling them? This post explains the homemade cockroach killer with vinegar you can use to get rid of these critters.

A female German cockroach, for example, produces from 4 to 8 egg capsules during their lifetime. Each capsule contains up to 48 eggs — Pennsylvania State University.

The alarming aspect is that roaches can settle unnoticed in your home, and by the time you become aware of their presence, their population may have multiplied significantly.

If you see a roach scurrying across your kitchen counter, that can be a reason for worry. These insects can harbor bacteria that have the potential to cause illnesses like food poisoning, and they can even trigger allergies in certain individuals.

Due to their notorious reputation for unhygienic habits, many homeowners facing roach infestations turn to the internet in search of do-it-yourself remedies and quick fixes. Among the suggestions commonly found is the use of vinegar. But does vinegar get rid of roaches?

Will Vinegar Make Roaches Leave?

While white vinegar is often suggested as a natural solution for getting rid of roaches, it does not actually have the power to kill these critters. It primarily functions as a cleaning agent rather than an effective method for getting rid of roach infestations.

Nonetheless, it can serve as a deterrent for roaches and aid in eliminating germs in the kitchen when used for cleaning purposes.

Keeping your house, particularly your kitchen, can help to prevent cockroach infestations.

The average home typically provides all the essentials that these pests need to thrive, such as food, shelter, and moisture. Cockroaches are known to eat practically anything, including garbage and excrement, so the crumbs in your kitchen act as an easily accessible meal for them. Maintaining a clean kitchen reduces the likelihood of roaches being attracted to a food source and establishing an infestation.

Apart from cleaning your kitchen counters, you can prevent roaches from entering your home by ensuring that garbage is tightly sealed and regularly disposed of. Maintain clear drains and clean kitchen appliances like toasters, such can accumulate crumbs. In addition to these steps, make sure to store food in airtight containers. Refrain from leaving dirty dishes in the sink, and securely store pet food as well.

Homemade Cockroach Killer with Vinegar

Homemade Cockroach Killer with Vinegar

A vinegar spray may help repel roaches, but it is not very effective at eliminating a roach infestation. Below are some of the ways to make homemade cockroach killer with vinegar:

1. Make a Vinegar Spray

If you would like to use vinegar as a repellent, you can make a spray using the following steps:


  • White vinegar
  • Water
  • Spray bottle

How to get rid of cockroaches with vinegar spray:

  1. Mix equal parts white vinegar and water in a spray bottle.
  2. Shake well to combine.
  3. Spray this mixture along the baseboards of your home, in the backs of drawers, around the garbage can, under the sinks, and anywhere else you’ve seen roaches.

Roaches are attracted to food and water, so keep your home clean to keep them at bay.

For a more effective natural solution, you could use a mixture of boric acid, flour, and sugar to attract and kill roaches, or diatomaceous earth, which is a powder that damages their exoskeleton and kills them.

Note that these substances can be harmful or toxic to humans and pets if ingested or inhaled, so use caution and keep them out of reach of children and pets.

2. Clean with Vinegar Solution

A vinegar solution can be a part of your homemade cockroach killer with vinegar to dissuade roaches. Roaches dislike the smell of vinegar and such cleaning also helps in eliminating food residues, grease, or moisture that may attract roaches.

The vinegar solution assists in erasing the pheromone trails roaches use for navigation. Follow these steps to make a vinegar cleaning solution.

  • Prepare a cleaning solution by mixing equal parts of white vinegar and water in a spray bottle or a bucket.
  • Use this solution to wipe down countertops, kitchen appliances, bathroom fixtures, floors, and other surfaces that roaches are likely to traverse.
  • Regularly clean food crumbs, spills, and other potential roach attractions with this vinegar solution.
  • Remember to also clean hidden and hard-to-reach areas like behind the refrigerator, stove, and other appliances.

3. Vinegar-Based Roach Bait

Vinegar can also be used in homemade roach baits. This typically involves baking soda and sugar. The sugar works as an attractant, while the baking soda reacts with vinegar ingested by the roach, causing it to die. However, this method is not highly effective against a large infestation.

  • Mix equal parts of baking soda and sugar in a shallow dish or a small container.
  • Place this mixture in areas where you’ve noticed roach activity.
  • Keep a separate container of white vinegar nearby.
  • Once you observe roaches gathering in the baking soda-sugar mixture, pour in the vinegar.

Vinegar will react with the baking soda to create a gas, which can kill roaches. Note that this is a less effective method, and more suited to dealing with a small number of roaches.

4. Vinegar and Essential Oils Spray

Some essential oils, like peppermint and cypress, are said to repel roaches. You can mix a few drops of these oils with your vinegar-water solution to enhance its repellent properties. For these steps:

  • Prepare a mixture of equal parts of white vinegar and water in a spray bottle.
  • Shake the bottle well to ensure the mixture is thoroughly combined.
  • Spray this solution along areas where you’ve noticed roach activity such as baseboards, behind appliances, cracks and crevices, etc.

The vinegar scent should then repel the cockroaches.

Why You Have Cockroaches in Your House in the First Place

Even if your home is meticulously clean, it is still possible to encounter cockroaches, as certain species are not solely attracted to cleanliness.

Food is not the sole factor that draws them to your house; weather conditions also play a significant role. As temperatures begin to drop in the fall, roaches may venture indoors in search of warmth. They may seek shelter from heavy rain, as water threatens to drown them.

The presence of cracks and crevices in and around your home provides easy access points for roaches. If you have abundant vegetation or roach-friendly environments, such as wood piles, near your foundation, you are essentially paving a clear pathway for them to enter. The solution is usually to ensure that your foundation remains free of debris and utilize a sealant, such as caulk, to seal any cracks or openings in your home.

Seek Assistance from Your Local Roach Control Professional

When it comes to eradicating roaches, you want to enlist the services of a pest control professional. While DIY homemade cockroach killer with vinegar may appear affordable and convenient, they often prove to be relatively ineffective, resulting in potential long-term expenses.

Pest control professionals have the necessary training to effectively address roach infestations and can perform a comprehensive inspection of your home to assess the severity of the problem. Often, a visible roach is just the tip of the iceberg, indicating a more extensive infestation lurking unseen. Roaches frequently inhabit less accessible areas within residences, such as crawl spaces and behind walls. Pest control professionals can expertly locate and address infestations in these concealed spaces.

In addition, different cockroach species exhibit varying responses to treatment methods. But with a professional pest control company, you can accurately determine the specific roach species causing issues in your home and receive expert guidance on the most suitable treatment approach.
