Does Lysol Kill Roaches and Bugs?

Nature has designed bugs, including roaches and palmetto bugs, with an open circulatory system. This means that, unlike other creatures, they do not breathe through the mouth and lungs. Instead, they rely on respiratory openings on the surface of the body. These openings are called Spiracles.

Does Lysol Kill Roaches and Bugs? Yes! Lysol kills roaches and bugs by physically interfering with respiration. This is achieved by clogging the respiratory openings situated on the body and hence choking them to death.

Lysol is a disinfectant spray made of a solution that contains alcohol and other antiseptic chemicals. Due to low surface tension, Lysol has excellent penetrating and absorbing properties due to low surface tension, making it ideal for destroying eggs. So I am going to explain in detail does Lysol kill bugs?

Also, note that just like Lysol, other disinfectant sprays can also kill roaches. So can disinfectant spray kill bugs? Yes, a disinfectant spray will block the respiratory openings of roaches and bugs to choking them to death.

How does Lysol kill roaches and other bugs?

The market is flooded with insecticide sprays, and almost all of them contain a chemical neurotoxin that affects the nervous system of insects, including roaches. No doubt that insecticide sprays are pretty effective and quick in action, but they do have downsides. Impact on environment and aquatic life is notable, among others.

As discussed above, insects breathe through openings on their bodies, and physically blocking them will suffocate them to death. Lysol is intended for antisepsis due to the high percentage of alcohol. But it also contains a sticky substance called Benzalkonium Chloride, which makes it sticky.

Like any other sticky substance, if Lysol is sprayed on the roaches and bugs, it will either directly block the openings or cling the wings and legs to the body and block them. Hair spray will also kill a roach. You can check my article on does hairspray kills roaches here.

Quick Caution: It must be kept in mind that Lysol works when directly sprayed on the bug. It does not work like a typical insecticide spray.

How quickly can lysol kill roaches and bugs?

In most cases, humans can’t withstand hypoxia (lack of Oxygen) for more than 5 minutes. But you will be pretty amazed to know that bugs, including the cockroaches, can remain alive for up to 8 to 10 hours without Oxygen.

So how quickly can Lysol kill roaches? Once you spray Lysol onto the roach, it will immediately incapacitate the bug. It seems like the bug has died instantly, but Lysol actually takes between 6 to 12 hours to kill a bug or a cockroach.

Depending on personal preference, once you incapacitate the bug, you may squash it to make the job easy.

Do all type of lysol kill cockroaches?

Lysol is not the name of any chemical solution but is a registered trademark like Dettol. Just like Dettol is synonymous with a brownish-colored solution same is the case with Lysol.

Lysol comes in wipes, cloth disinfecting solutions, bleaches, and antiseptic sprays. So do all types of Lysol products kill cockroaches? No, you need to have antiseptic spray by Lysol. Other products will not work and will most likely fail to kill bugs.

It is interesting to know that Lysol has an excellent ability to destroy the eggs of roaches. This is due to the high concentration of alcohol. Learn more on how to get rid of roach eggs. So it’s now quite evident if does Lysol kill cockroaches or not.

Does Lysol kill beg bugs?

Lysol will kill bed bugs when applied directly to them. This is because it acts on the respiratory openings and physically clogs them; these openings are present in all insects, including bed bugs.

Although Lysol will kill bed bugs besides roaches, the killing time can vary depending upon the size. For example, a bug with a larger size will die soon than with a smaller body. This is because small-sized bugs, e.g., the German cockroaches, are better at surviving without Oxygen due to relatively less demand by the body.

Does Lysol kill ants?

Like other bugs and insects, ants also breathe Oxygen through spiracles located across its body. Lysol will block these tiny holes, and Lysol will kill ants if sprayed directly upon them. However, using Lysol to control ants is not an effective long-term solution. An easy way to get rid of ants is using an ant-killing bait on the ant’s path to and from nests.

Does Lysol kill spiders?

Spiders also breathe Oxygen through tiny openings in their body, so spraying Lysol directly on spiders will kill them, but since they are high up in the ceiling, it’s not an effective way to get rid of them. You may have to finish an entire bottle of Lysol to kill one spider. An easy way to kill spiders is with spider killer spray.

Is Lysol More Cost-Effective and better than insecticides to kill insects?

Insecticide sprays have revolutionized the way we exterminate bugs. They are readily available, cost-effective, quick, and powerful to kill bugs, including palmetto bugs. The insecticide sprays contain D-Allethrin and DEFENSA, two potent neurotoxins that act very quickly by interfering with nerve conduction.

Will Lysol Kill a Palmetto Bug

Apart from these benefits, the drawbacks to using insecticides spray include the damage to the atmosphere, aquatic life, and allergies to atopic people. On the other hand, Lysol spray is also effective at exterminating bugs but must directly be sprayed onto the bug and their eggs.

Given the above discussion, I conclude that Lysol is not better and cost-effective than an insecticide spray majority of the time. But if you do not have a readily available Insecticide spray, Lysol will do the job nicely.

You can also opt for natural palmetto bug repellants to keep these insects at bay.

Is it painful to kill roaches and bed bugs with hairspray?

Insects, including roaches and bed bugs, do not have emotions and are devoid of specialized pain receptors; therefore, they do not feel pain but sense irritation. This is built to protect them from environmental insults and dangers.

You may see a bug flapping wings and legs after they are sprayed with insecticide, but this is not due to pain but is the result of uncontrolled spasms elicited by the neurotoxin.

To make it brief, it may seem painful to kill a cockroach with Lysol, but they do not suffer any pain.
