Does Lysol Kill Spiders? [Yes, BUT…]

Nature has designed Spiders 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 Spiders?

Yes! Lysol kills Spiders by physically interfering with respiration. This is achieved by clogging the respiratory openings on the body and choking them to death.

Lysol is a 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 Spiders.

How does Lysol kill Spiders?

The market is flooded with insecticide sprays, and almost all of them contain a chemical neurotoxin that affects the nervous system of insects, including Spiders.

No doubt that insecticide sprays are pretty effective and quick in action, but they do have downsides. Impact on the environment and aquatic life is notable, among others.

As discussed above, insects breathe through openings in 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 Spiders, it will either directly block the openings or cling the legs to the body and block them. Hair spray will also kill a Spider.

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

How quickly can Lysol kill Spiders?

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

So how quickly can Lysol kill Spiders? Once you spray Lysol onto the Spider, it will immediately incapacitate it. It seems like the Spider has died instantly, but Lysol takes 6 to 12 hours to kill a Spider.

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

Do all types of Lysol kill Spiders?

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, the same is valid with Lysol.

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

It is interesting to know that Lysol has an excellent ability to destroy the eggs of Spiders. This is due to the high concentration of alcohol. So it’s now quite evident if Lysol kills Spiders or not.

Is Lysol More Effective Than Spider Killers?

Insecticide sprays have revolutionized the way we exterminate Spiders. They are readily available, cost-effective, quick, and mighty in killing Spiders.

The insecticide sprays contain D-Allethrin and DEFENSA, two potent neurotoxins that act very quickly by interfering with nerve conduction.

Apart from these benefits, the drawbacks to using insecticide 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 Spiders but must directly be sprayed onto the Spider and their eggs.

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

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

Is it painful to kill Spiders with Lysol?

Spiders 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 spiders flapping 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 Spider with Lysol, but they do not suffer any pain.
