Have you noticed spiders in and around your home? Although spiders technically can be beneficial to your home as they will eat other insects, it still doesn’t mean you should resort to simply living with spiders. In this guide we’ll be breaking down does lysol kill spiders and if we’d actually recommend it as a spider control method or if you should stick with more traditional pest management solutions. So let’s get started!

Does Lysol Kill Spiders?

Yes, lysol does kill spiders! Spiders have an open respiratory system which means they breathe out of holes along their skin referred to as spiracles. If these spiracles are clogged and blocked with a substance such as Lysol, the spiders won’t be able to breath and they will die. This is exactly what Lysol does to spiders, it blocks their ability to breathe and soon they will die from asphyxiation.

The biggest downside to using Lysol to kill spiders is that it only kills spiders if a heafty amount of Lysol is sprayed directly on the spider. Since the Lysol needs to block the spider’s spiracles, the spider needs to be dosed in Lysol.

Traditional spider control treatments don’t rely on asphixiation, and rely on insecticides to kill the spiders which means they can kill near instantly, as well as have lasting killing power if additional spiders walk through the area.

So if you have a severe spider infestation, I would recommend a traditional spider treatment such as the one below, rather than using Lysol for spiders.

How Does Lysol Kill Spiders?

Traditional insecticides generally use a neurotoxin that kills the spider from the inside out. The benefit of this is that the spiders simply have to walk through the area of treatment, and they can and will be killed by the treatment. The downside of this is that it’s slightly more dangerous to humans and pets, similar to using bleach to kill spiders.

Lysol kills spiders differently and it actually suffocates the spiders. As mentioned above, spiders breath out of their skin referred to as spiracles. Lysol is effective in covering and blocking these spiracles because Lysol has an ingredient in it called Benzalkonium Chloride which is a sticky and viscous material that can completely cover a spiders spiracles and not allow any oxygen into the spider. Thus, killing it via asphyxiation.

That being said, in order for this to work, the Lysol has to be sprayed directly on the spider to fully coat the spiracles, and suffocate the spider in the process.

How Long Does It Take For Lysol To Kill A Spider?

Because Lysol relies on fully suffocating the spider, it doesn’t kill spiders instantly. You’d probably expect spiders to suffocate in only a few minutes, but amazingly spiders can live for hours without breathing.

This means it can take anywhere from 2-8 hours to fully kill a spider using Lysol because that’s how long it can take for them to suffocate.

As you might have noticed, this isn’t the most efficient spider treatment available, but if you only have one or two spiders then it will get the job done. In my personal experience, you’re better off using a more traditional spider treatment.

That being said, you can slightly deter spiders because of the smell of Lysol.

What Should You Use To Kill Spiders Instead of Lysol?

As mentioned above, yes Lysol does kill spiders, but it really isn’t the most effective way to kill spiders. Killing spiders with Lysol involves you directly spraying the spider with Lysol and it can take hours for the Lysol to actually kill the spider.
