      Noticing ants moving across your kitchen counter or around the food can be annoying. Most of us  look for something handy to stop them immediately. Windex is often considered an option for getting rid of ants because it is readily available in most homes as a cleaner. Windex is a common household product; it can be considered a quick-fix solution. In this article, we'll find out whether Windex is an effective option for getting rid of ants and how to use it.

      Is Windex an Effective Ant Killer?

      Windex can be a temporary solution because until the queen is killed, the colony can’t be wiped out. As a result, the ants can eventually return. But Windex can be used as a quick ant control solution. If you spot a bunch of ants in your home, you can spray Windex to kill them instantly. After spraying Windex, wipe out the surface to remove pheromone trails of the ants, so that other ants don’t follow the trail. It is recommended not to squish ants because crushing them releases a chemical called oleic acid, which attracts more ants to the spot. Instead of solving the problems, this can make the infestation worse.

      How Windex Works on Ants?

      Ants breathe through tiny holes on their bodies called spiracles. When Windex is sprayed on them, the spiracles get blocked, and they suffocate. The ammonium in Windex also works like a quick ant killer. Wipe the area where Windex is sprayed to remove the pheromone(oleic acid) trails left behind by ants. These trails act like their road-map, so cleaning them disrupts the path for other ants.

      Windex can help remove the ants you can see, but it won't completely resolve the infestation until the queen is killed, as the colony will continue to exist if the queen is alive.

      How to Use Windex Safely in Homes?

      One advantage of Windex is that, although it is not completely non-toxic, it is less harsh than many indoor insect sprays. But be careful when using Windex to kill ants, because it wasn't originally designed as a pest killer.

      Threats to Pets and Children

      Windex contains ammonia that can be harmful if a pet or child accidentally swallows it. If it gets ingested, it may upset their stomach and cause discomfort. If it comes into contact with skin or eyes, it can cause burning and mild irritation. So, if you are using Windex at home with kids or pets, be careful. Keep the bottle out of the reach of kids and pets, and avoid spraying it anywhere they can directly touch.

      Household Solutions to Control Ants

      Professional pest control is the effective and most reliable way to remove ants, but you can try a few easy DIY methods:

      Baking Soda and Sugar

      The mixture of baking soda and sugar can act as a bait. The sugar attracts ants, and baking soda kills them.

      Sprinkle food-grade diatomaceous earth around places, especially around the entryway. This natural powder damages the ants' exoskeleton, causing dehydration.

      Cornmeal

      Cornmeal doesn't kill ants immediately, but it acts as a slow-working bait. Ants can't digest cornmeal, so when they eat it, it swells inside  eventually "leading” to their death.

      Vinegar

      Adding water and vinegar in equal quantities can serve as an ant repellent due to its strong scent.

      Borax

      Borax or Boric acid, when mixed with sugar, can act as bait because it disrupts ants' digestive systems if ingested.

      Strong smells can disrupt ants' scent trails. Items such as coffee grounds, peppermint oil, and lemon juice emit odours that confuse ants. Since ants depend on scent trails to move around, breaking these trails makes it harder for them to enter your home.

      Conclusion

      Windex can help you get rid of ants, but it is not a permanent solution. Windex works quickly, but only on the ants you can see, not on those hiding in the colony. Use safer home remedies or call a professional pest control for long-term relief from ants.  Use it carefully, especially around children and pets. Additionally, keep your home clean to prevent ants from returning.
