Can Disinfectant Spray Kill Bugs? [Yes, BUT…]

Nature has designed 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 Disinfectant Spray Kill Bugs?

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

Disinfectant Spray is a spray made of a solution that contains alcohol and other antiseptic chemicals.

Due to low surface tension, Disinfectant Spray 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 Disinfectant Spray kill bugs.

How does Disinfectant Spray kill 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 bugs.

No doubt that insecticide sprays are pretty effective and quick in action, but they do have downsides. The 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. Disinfectant Spray 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 Disinfectant Spray is sprayed on the 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 bug.

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

How quickly can Disinfectant Spray kill bugs?

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

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

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

Do all types of Disinfectant Spray kill bugs?

Almost all commercial sprays, including disinfectants, fragrances, etc., have a spirit as a solvent. Since the science is to stop the cockroach from breathing, they will penetrate the spiracles and kill the cockroach.

However, disinfectant wipes and stuff won’t kill bugs. However, antiseptic-type sprays are most effective in killing bugs.

It is interesting to know that disinfectant sprays have an excellent ability to destroy bug eggs. This is due to the high concentration of alcohol.

Is Disinfectant Spray More Effective Than bug Killers?

Insecticide sprays have revolutionized the way we exterminate bugs. They are readily available, cost-effective, quick, and mighty in killing 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 insecticide spray include damage to the atmosphere, aquatic life, and allergies to atopic people.

On the other hand, Disinfectant Spray 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 Disinfectant Spray is not better and more cost-effective than an insecticide spray. But if you do not have a readily available Insecticide spray, Disinfectant Spray will do the job nicely.

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

Is it painful to kill bugs with Disinfectant Spray?

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 bug with Disinfectant Spray, but they do not suffer any pain.
