You will notice that if an ant visits any area that has food, others will follow. There is a scent they leave behind when they find food so that the rest can also get there. Here is how to use Windex to get rid of ants at home.

  • If you have hundreds of ants swarming in an area, simply spray Windex directly on them.
  • Spread Windex on the ant’s trail and just let it settle so that they do not use the path again.
  • After moping, you may randomly spray Windex directly on the floor.
  • Wipe it with a clean mop so that it is equally spread to keep away ants and other crawling insects at home.
  • You can also spray Windex directly on your fence where the ants like to crawl.
  • Spraying Windex will also help in keeping ants away because it will disrupt those pheromones that ants use to communicate.

This will leave no chances of other ants coming into your house. You can also use Windex as an ant barrier especially if you spot the place where they use to gain access into the house. Simply spray it directly on the entry point and the smell will definitely turn them away.

Why is Windex not the Best Choice? 

While Windex can effectively kill and deter ants, it’s not necessarily the best or most sustainable choice for ant control. Windex is primarily a cleaning product, not an insecticide.  

Prolonged use of Windex to kill ants can potentially lead to the development of resistance in ants. Also, it may not be effective against larger ant colonies or certain species of ants. 

What are the Best Alternative options to Windex?

Diatomaceous Earth

Diatomaceous Earth is a natural powder made from tiny fossilized aquatic organisms known as diatoms. It kills ants by causing them to dehydrate when they come into contact with it.

It’s a safe and natural alternative to Windex, making it a good choice for households with children or pets. 

TERRO Ant Killer

TERRO Ant Killer is a ready-to-use ant killer spray that kills ants and other pests on contact. It also continues to kill ants for up to six weeks after application. This makes it a good choice for larger ant infestations or as a preventative measure. 


Borax is a common ingredient in many homemade ant killer recipes. When mixed with a sweet attractant like sugar water, ants will carry the lethal mixture back to their colony, killing the ants that consume it. 


Is Using Windex Safe as an Ant Killer? 

Yes, Windex can safely be used to kill ants. However, it should be used with caution around children and pets, and it should not be sprayed on areas where food is prepared or consumed. 

Can Windex be used as a long-term solution for ant control?

No, Windex is not a long-term solution for ant control. It can kill individual ants and disrupt their scent trails, but it won’t eliminate an entire colony. 

Is Windex safe for indoor use to control ants?

Yes, Windex can be used indoors to control ants. However, it should be used in well-ventilated areas and kept out of reach from children and pets. 

Will ants come back after using Windex? 

While Windex can kill ants and disrupt their scent trails, it does not prevent them from coming back entirely. If the conditions that attracted the ants persist, such as food sources or shelter, ants may return. 

Can Windex be harmful to pets or humans? 

Windex should not pose a significant threat to pets or humans when used properly. However, it can be harmful if ingested, or if it comes into contact with the eyes. Always use Windex as directed by the manufacturer and store it in a safe place out of reach of children and pets.
