Baking soda and vinegar: Sprinkle some baking soda over the ant colony and spray white vinegar on top of it. It forms soda foam and kills off the colony.
Baking soda only kills ants when they ingest it – will quickly kill them within a few minutes if they do consume it. The tricky part is that ants instinctually know to stay away from baking soda, so it's difficult to put it somewhere where they will ingest if they are already in your house.
Baking soda is one of the most effective way to take out an ant infestation. And, it is always a good idea to target the whole colony at once if you want to stop the outbreak in its tracks.
Use this white vinegar solution to spray all entry points of your home, try to spry all windows, doors, baseboards and the common paths that ants would travel within your home. Give about an hour for this solution to take effect, then after a few hours the ants should be dead.
Will Vinegar Kill Ants? The bad news is that vinegar doesn't really kill ants the same way insecticides or pesticides do. The chemical composition of vinegar isn't enough to poison ants. Homeowners can try drowning the ants in vinegar, but doing this with water only achieves the same effect.
Always remember that Vinegar is not a permanent solution to remove an ant infestation. It is reasonable to spread the solution thrice a week over the affected areas to remove ants slowly.
The most effective way of getting rid of ants permanently is to call a professional pest controller. They can eliminate an infestation as well as put measures in place to ensure you're never faced with one again.
The sugar attracts the ants, and the baking soda is what kills them: It reacts with the acid in their digestive system, and they explode. Place the mixture in strategic locations and wait for the baking soda to do its thing.
Peppermint is a natural insect repellant. You can plant mint around your home or use the essential oil of peppermint as a natural remedy for control of ants. Ants hate the smell, and your home will smell minty fresh! Plant mint around entryways and the perimeter of your home.
Baking soda by itself can already be appealing to ants, but one thing you can do to make it even more attractive to the ant colony is by mixing it with a sugar mixture.
Salt-boil salt and water into a mixture and once cooled, pour into a spray bottle and spray nooks and corners. Oranges-half fresh orange juice and half water sprayed around your home will keep the pests out and keep your home smelling nicely. Essential Oils-used like lemon or orange juices.
Case in point: the popular “tip” that Windex is a bug-killer—the truth is that while Windex can technically kill small insects like ants, it's not a suitable swap for tested insecticides, says Dr. Angela Tucker, manager of technical services for Terminix.
Natural deterrents.
Salt, baby powder, lemon juice, chalk, vinegar, bay leaves, cinnamon, or peppermint oil are a few items that you have around your home that will stop ants from coming inside. Lay these out in areas where you see ants, and they'll stop using that area as an entrance into your house.
While many people believe that salt is an effective way to get rid of ants, the truth is that salt may only temporarily repel certain species ants, rather than kill them. Ants live in a colony often consisting of thousands of ants.
Mix Borax with equal parts water and sugar to make a syrup, and leave it in the corners where you've noticed ants. This method will work to kill the entire colony in roughly 24 to 48 hours, as the worker ants will bring the liquid back to the nest.
Borax. Borax, a mineral used in many cleaning products, is lethal to ants, interfering with their digestive system. Create a syrupy paste with borax, confectioner's sugar and water. Put the mixture inside shallow containers with narrow, ant-sized openings and place them near ant mounds or wherever you see ants.
To use vinegar as a homemade ant spray, simply fill a spray bottle with a 50/50 solution of vinegar and water. Spray the solution directly on the ants and then wipe the area clean with a damp paper towel.
Mix 1/2 C sugar, 1 1/2 Tbsp Borax, and 1.5 C warm water. Soak some cotton balls in the mixture, and put them out near the mess of ants. The sugar attracts the ants, and they'll take the Borax with it back to their home. Eating the Borax kills the ants!
Erase The Ant Scent Trails
Simply sweeping and mopping your floors won't help to eliminate the scent trail that ants leave behind. Instead, mix up vinegar and water and spray areas where ants have been. Another recommendation is to use an Ammonia based cleaner to clean up the pheromone trail.
Mix one part water and one part apple cider vinegar in a spray bottle. Spray along the ant trails where you typically see the ants march in lines. Do this after you notice ants come into your home in large numbers. They follow the scent from ants that have gone before them.
That said, when combined with things like boiling water, vinegar, or baking soda, salt can be highly effective at getting rid of ants without having to rely on chemicals. Plus, it's something you likely have plenty of around the house - and it's super cheap!
