Does windex kill spiders and their eggs? – read on to find out

Dave Campbell

If there is an insect many people dread then it is the spider. Sorry, it is not an insect but it belongs to a class referred to as arachnoids. I am sure if you did some basic Biology I do not lose you right at the introduction. A spider is creepy with its 8 legs and some dull color
telling you to stay away. The worst of it is to find yourself in a room alone and that black-brown furry arachnoid is crawling towards you. It is quite freaking, right? It is not only you who feels that way about spiders; there are many who would take a run for their lives on seeing this creature regardless of its small size.

Well, if you have had an encounter with spiders you would be out looking for ways to kill them. There are many ways to kill a spider just like it is with the proverbial rat. However, I know you might have asked yourself this question: can Windex spray get rid of spiders? If you have then you came to the right place.

Windex, which has the chemical name sodium dodecylbenzene sulfonate, is one of the top pesticides that will kill spiders and get the creepy creature out of your way. It is a surfactant, in other words, one of the common ingredients of bath products. Windex, being a toxic pesticide like bleach will kill a spider will kill a spider within a few seconds of use. In addition, Windex kills a score of other insects such as bed bugs, just in case you are facing some other intruders into your home.

How to use glass cleaner as a repellant

Now that you know Windex glass cleaner is the perfect spider killer, you would also want to know how to use it. It is pretty straightforward to use Windex. You only need to get close enough to the spider and spray Windex on it. If spiders really send shivers down your spine, you may
want to find a safe distance as you spray.

Make sure you spray adequately on the spider and it will be dead in a short while (or should I say the threat is neutralized?). That is all it takes to kill a spider with this versatile pesticide. Once the spider is dead you should pick it up and safely dump it in your trash bin. It is that simple and you can go on with your business just like nothing happened.

Benefits of using this household spray

Of all the insecticides out there, why should you go for Windex? Personally, I have used it and will tell you why I keep using it not only on spiders but a plethora of other insects.

  • Very easy to use. There is nothing complex about using this spray. You just do it like you would with your body spray. It does not need any prior experience to use.
  • Very effective. Windex gets the job done. It will kill spiders within a few seconds of use.
  • It kills a score of other insects. Windex is your ultimate insect and other related creatures’ killer. If you have it, you can use it on other insects that may show up in your home.
  • It is a “green” pesticide. Since you will be using it in your home, you need to be sure it is not a health hazard. Windex is branded as an eco-friendly pesticide thus causes no harm to you or anyone else in your home.

Final thoughts

I hope now you have a solution to spiders that keep showing up in your house. It is time you teach these freaking arachnoids a lesson by sentencing them to death on sight. Always have Windex by your side and the spider problem will be the least of your worries.

However, if you keep seeing spiders in your rooms then you have a bigger problem than what Windex can handle. Maybe you have a
basement spider infestation and nest of spiders or there are some holes letting these creatures into your living or office space. Seeking the services of a terminator would go a long way to ensure that the problem is solved once and for all.
