Does Lysol Kill Roaches

Last Updated:

As a homeowner, the unwelcoming sight of roaches scurrying around your living spaces can be distressing and unsanitary. You might wonder if regular household cleaning products like Lysol spray have what it takes to eliminate these pesky pests.

In this blog post, we’ll delve into whether Lysol is effective against roaches, how it works, and explores alternative solutions for dealing with a roach infestation.

Key Takeaways

Lysol isn’t specifically made for killing roaches, but it can and will kill individual roaches.
Lysol works to kill roaches by penetrating their respiratory system and ultimately suffocating them.
Lysol isn’t as potent as pesticides, but can work well on a very small scale.

Does Lysol Kill Roaches?

Lysol’s effectiveness in combatting roach infestations may come as a surprise to many homeowners. Typically used as a disinfectant, Lysol is formulated to kill viruses and bacteria but can also be employed in the battle against these unwelcomed pests.

It can be sprayed onto these resilient critters or their hiding spots, such as under kitchen sinks and other dark places where cockroaches congregate. Lysol penetrates their respiratory systems through openings called spiracles. This causes blockage within their airways, ultimately leading to suffocation.

As expected, Lysol is not explicitly designed for pest control and is less potent than specialized pesticides or bait stations. However, targeting the nervous systems of various pests like cockroaches, using Lysol spray can still provide some level of relief from small-scale roach infestations if applied correctly.

By completely dousing a cockroach in Lysol, a cockroach will usually die within 5 minutes, but will likely be much faster. It’s possible for a roach to live up to several hours after being sprayed by Lysol, but these are definitely the outliers.

Roach-Killing Alternatives

In this section, we’ll explore Lysol alternatives and uncover various effective solutions to combat roach infestations. We’ll shed light upon other methods, such as deodorizing sprays, diatomaceous Earth, and pesticides, to help you eradicate these pests from your home.

Antibacterial And Deodorizing Sprays

Antibacterial and deodorizing sprays are commonly used in households to keep them clean and smell fresh. In addition, these types of sprays may also help control cockroach infestations.

Spraying an antibacterial or deodorizing spray can kill roaches by suffocating them.

It’s important to note that while this method can be effective in killing individual roaches, it is not typically the most efficient way to control a widespread infestation.

When using an antibacterial or deodorizing spray as part of your pest control plan, it’s essential to follow label instructions carefully.

It’s important to keep the area well ventilated particularly in smaller spaces such as bathrooms, RVs, or closets. Many of these products contain harmful chemicals that could be dangerous if ingested or breathed in over extended periods.

Pesticides are chemicals that kill or control pests, including roaches. However, using them cautiously and following instructions carefully is essential to avoid potential harm to humans, pets, or other insects.

Some pesticides may contain harmful ingredients such as organophosphates that can affect the nervous system of both humans and animals.

When using pesticides for roach control, ensure they are safe for indoor use and do not adversely affect aquatic life if accidentally washed down drains.

Although pesticides can help control roach infestations, they should be part of a comprehensive pest control strategy that includes good hygiene practices and regular cleaning routines.

In conclusion, pesticides can be helpful when dealing with a severe outbreak of cockroaches, but care must be taken before using them inside your home.

Diatomaceous Earth

Diatomaceous earth is a natural compound that can kill various insects, including cockroaches. It may sound strange, but the diatomaceous earth works by destroying the exoskeleton of bugs, which leads to their eventual death. However, this white powder is non-toxic and safe for humans and pets. It is also easy to use.

Although diatomaceous earth can help control a roach infestation effectively, it’s not an overnight solution. The process takes time because it relies on dehydration caused by the destruction of the exoskeletons over several days or weeks before roaches eventually suffocate.

It’s worth noting that while diatomaceous earth won’t harm animals or people when used correctly and in small amounts, it could be harmful if ingested or inhaled in significant quantities by pets or children.

When To Call Professional Pest Control Services

If you are dealing with a severe roach infestation, it may be time to call the professionals. Professional pest control services have access to specialized techniques and equipment that can effectively remove all traces of these pests from your home or business.

One significant advantage of professional pest control services is their ability to identify the type of roaches infesting your property and how they enter and exit the area.

It’s also important to note that cockroaches reproduce rapidly – so even if you think you’ve successfully treated one area of your space, there may be more hiding out elsewhere.

That’s why you should always contact a professional. A professional pest control service will conduct a thorough inspection and provide ongoing treatment until the problem is resolved.


Now let’s discuss some frequently asked questions about making your home free of cockroaches.

What Cleaning Products Kill Roaches?

Many cleaning products can effectively kill roaches. Lysol spray is one such product, as it contains benzalkonium chloride and alcohol, which suffocate pests by clogging their respiratory openings.

Bleach is another option that works well to eradicate these unwanted visitors. However, it’s important to note that using cleaning products alone may not eliminate a cockroach infestation.

Combining cleaning with other methods is crucial, like placing bait stations or calling in professional pest control services for a long-term solution.

How Long Does It Take for Lysol to Kill a Cockroach?

Heavily spraying a cockroach thoroughly with Lysol typically results in its death within about 5 minutes, although the process may occur even more rapidly.

While there are instances where a cockroach can manage to survive for several hours after exposure to Lysol, they are the outliers.

How Do I Disinfect My House From Cockroaches?

To effectively disinfect your house from cockroaches, thoroughly clean all surfaces and areas in the infested area. Use bleach and water to clean up any remaining droppings or dead roaches. Next, you can use an antibacterial spray like Lysol to kill any remaining roaches or their eggs on surfaces.

After disinfecting, prevent future infestations, such as sealing cracks and openings where roaches may enter, placing bait stations around the home, and keeping food stored in airtight containers.

Remember that while Lysol can be effective for killing cockroaches, other alternatives, such as pesticides and diatomaceous Earth, may also work well, depending on the severity of the infestation.

Does Mopping With Pine-Sol Kill Roaches?

Using Pine-Sol to mop floors and wipe down surfaces in the kitchen can be an effective way to keep roaches at bay. While Pine-Sol doesn’t kill roaches directly, its strong scent repels them due to their sensitive nervous systems and spiracles (back openings through which they breathe).

Additionally, Pine-Sol is registered with the EPA as a disinfectant when used at full strength, so cleaning with it can help eliminate any food or water sources that may attract roaches in the first place.

Final Thoughts

In conclusion, Lysol can kill roaches by suffocating them through their spiracles. However, there are more effective methods for dealing with an infestation. Other alternatives, such as pesticides and natural compounds like diatomaceous earth, are more efficient in getting rid of these pests.

Disinfectant sprays like Lysol may help kill roaches that come into contact with it, but they should not be relied on as a primary solution to the problem.
