Does Windex kill insects (Let’s Find Out)

Having a problem with crawling insects in the house but don’t have any insecticide besides Windex?

So you’re wondering, does Windex kill insects?

Windex can kill some small insects like ants, bed bugs, spiders, etc. But it can not be an alternative to insecticides. If you want a more natural remedy you can try a mixture of different household ingredients like vinegar or bleach. But don’t use Windex as an insect-repellent alternative.

Can You Use Windex Like an Insecticide? 

No, Windex can not be used like an insecticide. It is a cleaning product that can kill small insects such as ants, bugs, spiders, and mosquitoes. But it doesn’t work against heavy infestations or big bugs.

Windex is made up of ingredients like ammonium hydroxide, isopropanolamine, water, etc. But these ingredients are in the bottle at a moderate amount suitable specifically for glass cleaning.

Insecticides, on the other hand, are specifically designed with active ingredients targeted to kill insects. They are formulated to work against heavy infestations.

So, you shouldn’t use Windex as an insecticide. However, a large amount of this spray can kill small insects. And it might make the big ones unconscious. So you can eventually kill them using a broom or other tools.  But this is a solution for more of an occasional insect problem.

Does Windex Kill Insects? 

As we discussed, Windex can kill small bugs but it is not enough for infestations. But which small bugs can it effectively kill? 

Well, here’s a detailed discussion on whether Windex can kill insects. But first, let’s take a look at the table for an overview:

Insects Name Does it Kill or Not?
Ants Instantly kill them
Flies Can knock them off the air; not fatal
Wasps Can slow them off; not fatal
Cockroaches Temporarily unconscious
Centipedes Bigger in size so harder to kill; but can make them unconscious
Springtails Can kill single springtails but not enough to kill an infestation
Gnats Can’t kill
Mosquito Can kill them
Spiders Can Kill
Bees Can kill
Bedbugs Can kill
Crickets Can repel some crickets away
Lizards Can stun it for a while but can’t kill
Rodents No Impact

Now let’s move on to a more detailed discussion on this:

Does Windex Kill Ants?

Yes, Windex can instantly kill ants when sprayed on directly. The ingredients of Windex are poisonous to ants. So it is able to take down ants within a few minutes of spraying. But it might not be enough to kill the biggest ant in the world.

It’s best to use all-purpose indoor insecticides for those cases. Another effective ant killer is Vinegar and peppermint oil.

Does Windex Kill Flies?

No, Windex can’t kill flies. A direct spray of Windex creates soapy films on the fly’s wings. This stops them from flying and knocking them off the air. You can then kill them with a fly swatter.

For an infestation problem, it’s best to use products like EcoVenger by EcoRaider All Purpose Insect Control. This product is designed to kill flying insects.

You can also try the fly traps. And if the problem is out of hand contact the local pest control for complete removal.

Does Windex Kill Wasps?

No, Windex can’t kill wasps. Spraying Windex on wasps will slow them down. As it takes over their senses and numbs their antenna and legs. You can then easily kill them off with a swatter.

Try the Ortho Home Defense Hornet & Wasp Killer to remove the wasps completely from your house. Other insects like yellow jackets and mud daubers can also be killed effectively with this spray.

Does Windex Kill Roaches?

No, Windex cannot kill roaches. The ammonia in the Windex temporarily makes the roaches unconscious. So it is best to squash and remove them right after spraying.

Harris Diatomaceous Earth Crawling Insect Killer can get rid of the cockroaches from every corner of your house. You just need to apply them into the cracks and crevices.

Does Windex Kill Centipedes?

No, centipedes cannot be killed with Windex. Centipedes have a hard exoskeleton making it hard for Windex to penetrate and break it down. As a result, centipedes may only be slowed down or unconscious for a couple of minutes.

To eliminate them completely try the Ortho Home Defense Insect Killer for Cracks & Crevices Spray Foam. This can kill centipedes on contact and get rid of crickets, ants, fleas, etc.

Does Windex Kill Springtails?

Yes, Windex can kill springtails. If you find one or two in kitchen cabinets you can use Windex to kill it. But infestations in the basement will require professional-grade Tempo SC Ultra For Insects to eliminate them.

Does Windex Kill Gnats?

No, Windex can’t kill gnats as effectively as a dedicated insecticide like Wondercide – Mosquito and Fly Aerosol Spray. Windex may stun it or make it unable to fly for a couple of minutes. You can get rid of it with a fly swatter then.

But for a more effective solution in the case of gnats use insecticide. However, do be careful while using it as these ready-to-use sprayers can stop working sometimes. And it is a hassle to get them fixed.

Does Windex Kill Spiders?

Yes, Windex can kill spiders. Small spiders can easily be destroyed by spraying a small amount of Windex on them. You can also try the Exterminator’s Choice – Spider and Web Defense Spray for better results.

Does Windex Kill Mosquitoes?

Yes, Windex can kill mosquitoes. The ammonium hydroxide in Windex is effective enough to get rid of mosquitoes. But for a permanent solution seek help from professionals and keep areas around the house clean and dry.

Does Windex Kill Bugs?

Yes, small bugs like stink bugs can be killed with the help of Windex. The ingredients in Windex are toxic enough for bugs to get rid of them completely.

Does Windex Kill Bees?

Yes, small insects like bees can be killed by Windex. You can easily kill them off with a few whiffs of Windex. You can directly spray onto the source repeatedly. Your house will be free of bees within a couple of days.

Does Windex Kill Bed Bugs?

Yes, you can easily kill bed bugs with a couple of sprays of Windex. Ingredients in Windex are toxic enough for these small bugs and get rid of them.

Does Windex Kill Crickets?

Yes, Windex can kill crickets. But this can only work if there are only a few crickets in the house. In order to eradicate the whole population you need Ecologic Ants & Roach Killer.

Otherwise, it might come back soon. You can also try various baits and granules to control crickets.

Does Windex Kill Lizards?

No, you can’t kill a lizard with Windex. But at the very least it can stun the lizard for a couple of minutes. This you can take advantage of and kill it with the help of some garden tools.

For a lizard repellent try using the Exterminators Choice Lizard Defense Spray. But remember lizards are beneficial for the ecosystem, so only use the spray in case of infestation.

Does Windex Kill Rodents?

No, Windex can’t kill any rodent. Glass cleaners such as Windex are not strong enough to kill rodents. You should try using mice baits or Motomco Bromethalin Meal Bait to get rid of rodents.

What’s the Alternative for Killing Insects?

As we discussed above, Windex can effectively kill some small insects. But for proper pest control, it’s best to follow the tested insecticides and recommended home remedies.

However, for a more natural solution to insect problems follow the home remedies below-

Option 2: Home Remedies

Here are a few effective home remedies you can use to kill insects:

Coffee Grounds

A few sprinkles of coffee grounds around your house perimeter will keep ants and crawling insects away. The strong smell of coffee grounds is repulsive to insects and helps to keep them away.

Vinegar and Peppermint Oil

In order to repel ants, make a mixture of 1/4 cup of white vinegar, 10 drops of peppermint or eucalyptus oil, and 2 cups of water in a spray bottle. Spray this mixture around the area infested by ants.

Vinegar’s acidic nature kills insects by breaking down their exoskeletons. The strong smell of peppermint oil on the other hand is repulsive to many bugs as well.

Garlic-mint insect spray

For outdoor pest control, this homemade spray is perfect. In a bowl take 1 tablespoon of mineral oil,1 teaspoon of cayenne pepper,1 clove of minced garlic, a handful of mint leaves,  2 cups of water, and 1 tablespoon of dish soap.

Stir the ingredients thoroughly. Then place the mixture on the stove. Let it simmer until it reaches a boiling point. Afterward, keep the mixture in a cool place and let it sit overnight. You can spray it around your yard the next day.

Garlic contains sulfur compounds that are harmful to insects while mint contains natural insecticide menthol. When combined together these ingredients create an insecticide that can kill and repel insects. Such as mosquitoes, ants, and other crawling bugs.

Neem Oil & Soapy Water

You can kill and stun cockroaches by spraying soapy water directly on them. And a mixture of a few drops of neem oil with water can repel insects as well. You need to spray the mixture in the corners of your kitchen to repel insects

Azadirachtin, the most active component in neem oil, reduces insect feeding and acts as a repellent. It also interferes with insect hormone systems, stopping growth, egg laying, and other life cycle behaviors

Soapy water on the other hand melts away cockroaches’ protective outer coating and blocks their spiracles. This makes it harder to breathe and eventually leads to cockroaches being dead.

Bleach

To create a solution that effectively kills insects, mix one part bleach with ten parts water. Bleach contains oxidizing agents like sodium hypochlorite, highly effective in killing crawling insects like ants and cockroaches.

It breaks down their exoskeletons and dehydrates them enough to kill them eventually.

On the whole, Windex can kill small insects, but not an alternative for insecticides.  But with the remedies and suggested insecticides, getting rid of insects won’t be a hassle for you.
