Roaches are common household pests, and finding an effective way to keep them away is crucial for maintaining a clean and healthy living space.

One such solution is using Lysol, a popular disinfectant and cleaning product, to repel these unwelcome insects. The main question that arises is whether Lysol can effectively keep roaches away or kill them.

While Lysol is not designed as an insecticide, its use may keep away some roaches, but it is essential to consider other methods for more permanent solutions.

Can Lysol kill roaches is what we will explore today.

Lysol’s Effect on Roaches

Is it Effective?

The combination of alcohol and benzalkonium chloride present in Lysol might kill a few roaches if you spray it directly on them. When these ingredients stick to the roaches’ bodies, they can cause their death.

However, it’s important to note that while Lysol can kill roaches when sprayed directly onto them, it cannot be relied upon as a standalone treatment method for a roach infestation.

Basically, it will not get rid of your cockroach problem.

Long-Term Prevention

As a disinfectant, Lysol can help to clean and sanitize surfaces in your home, which may indirectly prevent the attraction of roaches.

Regular cleaning and disinfecting can help remove potential food sources and hiding spots for these pests, making your home a less attractive environment for them.

However, relying solely on Lysol for long-term roach prevention is just not going to work at all.

It is crucial to integrate other pest control methods. You will also need to seal entry points, fix water leaks, and use other insecticides or baits, to have a comprehensive approach to keeping roaches at bay.

Lysol Properties

Active Ingredients

Lysol contains several active ingredients that contribute to its effectiveness against some pests, including roaches.

The main active ingredient in Lysol that can kill roaches is phenol, which causes neurological damage to the pest, eventually leading to its death. Other ingredients in Lysol include water, ethanol, and fragrance.

Roaches and Their Habitat

Roaches are resilient pests that can adapt to a wide range of environments. To effectively combat these insects with Lysol or other means, it’s essential to understand their habitat and the conditions they prefer.

Common Species

There are numerous species of roaches, but a few are more commonly found in homes and urban settings. These include:

Each species may have slightly different habitat preferences, but they generally thrive in warm, moist areas with access to food sources.

Preferred Living Conditions

Roaches prefer environments with the following conditions:

  1. Warm temperatures: Cockroaches are cold-blooded and rely on warm temperatures for survival.
  2. Moisture: They need moisture to survive and are often found in damp areas such as kitchens, bathrooms, and basements.
  3. Food sources: Roaches eat almost anything, from crumbs to cardboard, making most human habitats ideal for them.
  4. Shelter: They seek shelter in small cracks, crevices, and other tight spaces to evade predators and hide from the light.

Understanding the habitat preferences of roaches can aid in creating targeted strategies to deter them from settling in your home or property.

Alternative Roach Control Methods

Chemical Treatments

Aside from using Lysol, there are several chemical treatments available for controlling roaches. One of the most popular options is using insecticides in the form of baits, sprays, or powders.

Roach baits are often used indoors, as they attract and poison roaches with minimal risk to humans and pets. An example of a reliable roach bait is gel bait, which can be applied in small amounts near roach activity areas.

I use the gel all the time for my rental properties because it works to kill roaches. I also use IGR which regulates their growth and stops them from reproducing.

Sprays like residual insecticides can be applied in cracks, crevices, and other areas where roaches hide. Always ensure to follow the label instructions when using chemical treatments to prevent any harm to yourself, family members, or pets.

Natural Remedies

For those seeking an eco-friendlier approach to roach control, natural remedies can offer a possible alternative.

A popular natural remedy is diatomaceous earth, a natural powder that damages the exoskeleton of roaches, ultimately causing them to dehydrate and die. This can be sprinkled around the areas where roaches are frequently seen.

I have used this before but can’t really tell you if it worked or not because I have always had to use insecticide, gel, and IGR to kill them all.

Another natural option for controlling roaches is using a mixture of equal parts baking soda and sugar.

The sugar attracts the roaches, while the baking soda reacts with their acidic digestive systems, eventually killing them. Simply place the mixture in small containers or on jar lids and distribute it in areas where roach activity has been noticed.

Baking soda is a natural way to maybe kill a few roaches, but you will not get rid of them all using it.


As we’ve discussed throughout the article, Lysol does have the ability to kill roaches, primarily by interfering with their respiration. However, relying solely on Lysol as a method of keeping roaches away might or killing them is just not going to work.

While it may kill some cockroaches, it is essential to address the reason for the roach infestation, such as food sources, moisture, and access points in the home.

A combination of proper sanitation, exclusion measures, and professional pest control services can offer a more permanent solution for keeping these pests at bay.

Remember, Lysol is designed as a disinfectant and not as a pesticide. It is always advisable to use products specifically designed for pest control to achieve the best results.
