Baking soda and powdered sugar: Spreading baking soda with powdered sugar mixture with equal parts may disrupt the digestive systems of ants and kill them. Vinegar: Wiping ants with a solution of equal parts of vinegar and water or only vinegar may work the best.
Use citrus, like lemons, oranges, or grapefruit and harnesses the power of d-limonene — the acidic oil found in the peels. This oil is toxic to ants (so it will kill them on contact) and it messes up their trail, so live ones won't be able to find the food source.
Straight white vinegar makes a great ant spray. You can saturate ant trails to kill on contact, or spray counters and other areas and either wipe up after a few minutes or allow the treatment to dry in place.
Ants hate the smell of strong citrus fruits. Save your orange, lemon and grapefruit peels and scatter them around entry points. It's a natural way to deter ants without harming them.
Spray Tea Tree Oil
Like peppermint essential oil, ants can't stand the smell of tea tree oil and try to avoid it at all costs. Use the same peppermint oil spray bottle method or soak cotton balls in tea tree oil and place them at every entry point.
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.
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!
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.
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.
White vinegar and water: Take a spray bottle and fill it with a solution of equal parts of vinegar and water. Spray the solution on the ants and their entry points. A mixture of dish soap and water: Make a mixture of dish soap or dishwashing liquid, put in a spray bottle and shake it well. Spray it on the ants.
A sudden ant infestation in your kitchen means there is a food source somewhere. The food can be honey, sugar, syrup, meat, fats, breadcrumbs, etc. Once the ants determine these food sources, they form long trails to connect their colonies to the food source.
There is also a chance that you can contract salmonella from eating food that ants have come in contact with. By crawling across your food, they can spread salmonella for you to ingest. The best way to avoid these situations is to engage in proactive ant prevention measures and professional ant control services.
#4 Using vinegar to kill ants
Unfortunately, it doesn't work. Vinegar does not kill ants in the traditional sense: you spray it, and the ant dies. The only way this remedy is effective is if the ant drowns in vinegar (though water accomplishes the same thing).
Try pouring a line of cream of tartar, red chili powder, paprika, or dried peppermint at the place where you think ants might be entering the house; they won't cross it.
Ants-Be-Gone Spray: Mix equal amounts of white vinegar and lemon juice in a spray bottle, and gently shake. Spray around windows and door frames to stop ants from entering. Spray ants spotted in the home to eradicate them.
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.
You can eliminate the pheromone scent that forms ant trails by spraying a mixture of water and vinegar onto it. Mix equal parts white vinegar and water in a spray bottle, spray down the ant trail and wipe up with a paper towel. The scent of vinegar also acts as an ant deterrent, but will only last for four to 48 hours.
Mix one part powdered sugar with one part baking powder, and leave the mixture in corners of your kitchen where ants are located. The ants will be drawn to the sweetness of the sugar, but it's the baking soda that will kill them when ingested.
Try combining three parts powdered sugar with one part boric acid. The sugar will lure the ants in and the boric acid will kill them, Pereira says. Liquid is better—adult ants prefer to drink their food—so water this stuff down a little. “I recommend this to a lot of people,” Pereira says.
Most species of ants, including carpenter ants, dislike the strong scent of vinegar, which is why mixing it with water is enough to repel them. It's important to note that while the vinegar messes with the scent trail and prevents them from returning, the solution isn't enough to kill them.
