This is the first phase before the pest feels the effects.

Having paralyzed the spider, it begins to dehydrate it, thus leading to its eventual death. These all occur quickly, in a matter of minutes.

Therefore, the course of treatment shouldn't be particularly lengthy.

The cleaner's inclusion of ammonia (actually, ammonium hydroxide) helps to explain why Windex is so effective against spiders and other pests.

Other pests are subject to the same effect. However, you'll need to spray a sufficient amount of Windex on the target pest for this to be possible.

Spiders come in different species, sizes, and colors. No matter what kind of spider you are battling, one thing is for certain: no one should have access to your scope. Perhaps that's what drove you here.

Fortunately, there are countless techniques for getting rid of spiders, from artificial to organic ones. Knowing that you can get rid of spiders from your home using some common solutions will ease your mind.

Method 1: Use of Vacuum Cleaners

If you frequently travel, stay in places for a while, and leave your home unattended, you probably know how annoying spiders can be. It's difficult to keep them in check. To handle them, you must commit time and money.

And a vacuum cleaner is one of the things that will help you get your home back free of spiders! Yes, a vacuum cleaner doesn't just clean sawdust, debris, and pet hair! Additionally, it can remove spiders from your area.

And yes, using a vacuum cleaner does not require an engineering degree. In truth, it takes care of everything. It's up to you to find the ideal environment for the task; do that, and you'll have completed half the work.


  • Ensure that the Vacuum sac is empty and clean
  • Adjust the cleaner to the maximum setting
  • All you need to do is use the cleaner to suck up any spiders you see.

Method 2: Use of Vinegar

One of the most useful chemicals in our homes is vinegar. We use it to carry out a variety of housework tasks. Exterminating spiders in the event of an infestation is one more use to add to its lengthy list.

Vinegar combines well with water to make a chemical hazard that will leave your house redeemed of spiders, thanks to its strong acetic acid, which is hostile to spiders. In fact, vinegar won't just kill the bugs; it also acts as a repellant to others – and that wins your future battle before it begins.

However, you must take care not to use excessive amounts of water. A lot of water in the mixture will affect its potency by diluting the acid.


  • Mix equal parts of vinegar and water
  • Pour the mixture into a spraying bottle
  • Spray the mixture onto a spiderweb or a crawling spider.

Method 3: Use of Insecticides and Pesticides

To kill and get rid of pests, we spray insecticides and aerosol treatments under and around furniture, in cracks along sideboards, and in crevices around sideboards. These pesticides build a barrier that repels spiders and kills them. That said, this may be an excellent way to get rid of significant spider infestations.

The various chemical components found in pesticides make insects and spiders uncomfortable. A spider will suffocate and perish if a pesticide is sprayed directly on it. But spiders aren't really that stupid. They are sensitive to their environment, and they wouldn't just walk through where you have already sprayed.

So, the best way is to locate them and spray directly to eliminate them. This method will go a long way to deter other insects and bugs away from your home.

However, do not forget that many insecticides and pesticides include chemicals or poisons that pose significant harm to you, your children, and your pets, so use them with caution and follow all label warnings.

Method 4: Squish the Spider

The first thing that comes to mind when you see a spider is to squash it. For most of us, locating the nearest shoe becomes the next move whenever we see a spider. And yes, it's reliable, user-friendly, and delivers instant results.

Using a tissue, you can also squeeze one. But once more, not everyone has the courage to even look at a spider, let alone touch one; this is something for the brave.

But take caution, as spiders can be aggressive and even bite you. Spider bites effects may be short-lived – but that is not always the case. Life-threatening venom can be found in the black widow and recluse. So, if you choose this method, take care to avoid coming into direct contact with the spider through your skin.

How Long Does Windex Take to Kill Spiders?

A spider exposed to Windex technically takes 1 to 15 minutes to pass away. You see, in order for death to occur, spiders must first absorb sufficient amounts of ammonium hydroxide and sodium dodecylbenzene sulfonate.

One minute is a near-instantaneous time frame in which death can occur. But that isn't always the case. Sometimes the process can drag and can take up to 15 minutes.

What then is the reason for this noticeable difference?

Well, there are two determining factors here;

  • The content level of these two killer ingredients in Windex
  • The age of the spider

Regarding the concentration, the more ammonium hydroxide there is in Windex, the quicker death is likely to happen. This rule also holds true for sodium dodecylbenzene sulfonate.

About the age, baby spiders get the short end of the stick with exposure to Windex. As you can see, adult spiders are more resistant to chemicals than their younger counterparts. It will therefore take longer for them to die from the deadly components in Windex.

Is Windex Good for Killing Bugs and Insects?

Yes, Windex is effective at killing insects and bugs. You see, as we have mentioned, Windex contains a wide range of chemicals. Injurious to both bugs and insects, these chemicals are persistent.

However, Windex is a window and glass cleaner. Though it can eliminate bugs and insects, you should not use it primarily for this purpose. So, in your bid to eliminate bugs and insects in your home, look for commercial insecticides and pesticides as they are manufactured specifically for that reason.

Is Windex Harmful to Pets?

While it can be harmful to pets, Windex is more often fairly safe for your furry friends. The danger part comes in the ammonia and glycol ethers it contains.

Compared to other household cleaners, Windex poses less danger to pets. But that doesn't mean it isn't harmful. It is because it has some traces of ammonia and glycol ethers, which we all know to be unsafe for pets.

When inhaled or ingested, ammonia can affect growthfertility, and respiratory health in pets. And even though it's unlikely that the ammonia concentration in Windex will result in any of these, it's always a good idea to be cautious when it comes to your pet's health.

On the other hand, glycol ethers can have similar effects to those of ammonia. For example, it may lead to pet infertility. Other side effects of this compound include birth defects, retard development, early embryonic death, to mention but a few.

Therefore, even though Windex won't harm your pet or have any other obvious effects on it, you should always treat it like any other toxic household chemical.

Option 1: Frequent Cleaning of the House

The comfort of your home requires more than simple cleaning. No, cleaning your house also has other advantages, one of which is preventing spiders from entering.

Spiders aren't dumb! Whenever they see a cobweb in your space, they know that the place is sustainable for them.
