Invasion of Ants & How to Exterminate Them Naturally

Ant Extermination Instructions

Dealing with the Ants Already in Your Home

Probably the most commonly used ingredient in house ant control is Borax. A 50/50 solution of Borax mixed with sugar placed in a small cap works, since most ants are drawn to sweet things. Jonathon Hatch writes on Get Rid of Things that the sweet-based ant baits work for getting rid of Sugar Ants (a.k.a. House Ants or Pavement Ants; those little brown ants that make mounds in the pavement), Pharaoh Ants (golden ants with voracious appetites), and Argentine Ants (long dark ants). If you live in the south where red fire ants swarm or have carpenter ants, unfortunately insecticides seem to be most effective.

Besides Borax, you could also sprinkle a baby powder firewall near the ants’ point of entry to make ants inside your home lose their scent trail, get lost, and eventually die.

Keeping Ants at Bay

To discourage ants from coming inside your house, the baby powder trick may work as well because ants won’t climb over the powder. There are other options that also involve scent or clever uses.

  • Put cucumber slices near cracks or entry points because ants apparently hate cucumbers.
  • Draw chalk lines around your doorways and windowsills—as with the baby powder, this may work because ants don’t like particles sticking to their feet.
  • Put bay leaves or sprinkle cayenne pepper where the ants are coming in; according to Planet Green, ants hate the scent of these.
  • Make a cleaning solution of vinegar, water, and about ten drops of tea tree oil and spray it around your counters/doorways/etc. Also similar to the baby powder trick, this makes ants lose their scent trails and stop coming around (hopefully).
  • Cornmeal: Place anywhere you see ants invading your home. The little worker ants will then eat the cornmeal and die because they can’t digest it. One kiss up worker ant will take it back to the Queen where she will ingest it. Then Bamm! The Queen is dead!
  • Smelly Stuff: Basil Leaves and Cinnamon: The smell of basil and cinnamon apparently makes the ants gag and they are said to run screaming from the house. Place fresh leaves and ground cinnamon wherever you see the ants. You could also try various other spices to see which ones will cause them to wrinkle up their little noses and run. (You will need a magnifying glass to see their wrinkled noses 😉

Regularly cleaning up in your kitchen, taking out the trash, and sealing door sills and window sills are also all good measures.

How to Get Rid of Ants in the Garden Naturally

Ants are one of those insects that most people just can’t stand. Although they do have their good points–and some do a lot of good for your garden–there are some species of ants which are dangerous, and these are the ones you don’t want to keep. Fire ants, in particular, can cause a good deal of pain with their toxic bites. Other species of ants, such as carpenter ants, can cause damage to structures, so you don’t want them hanging around either. Don’t worry, though–there are several natural ways to get rid of these pesky insects that may be living in your garden. Read on to learn how to get rid of ants in the garden naturally.

Things You’ll Need
  • Vinegar
  • Water
  • Black pepper


  • Try a vinegar spray. Mix three parts vinegar with one part warm water, and spray around the perimeter of the garden. If you know where the ant hill is, you can spray the mound directly.
  • Sprinkle freshly ground black pepper in your garden around your plants. Ants won’t cross it, and it doesn’t cause any harm to you plants.
  • Grind up some chalk, and sprinkle it around the garden. Ants will stay away. If they’re already in the garden, use the vinegar and water mixture spray, and once they’ve gone, use the chalk to keep them out.
  • Shake out a line of baby powder around the garden. For some reason, ants don’t seem to like the smell, and won’t go near any part of the garden that has a baby powder smell.
  • Find the ant hill, and pour corn meal on top of it. Ants will eat the corn meal, but they can’t digest it, so they will die. If you hate the idea of killing ants, put a jar of honey in a tree near your garden. The ants will relocate so they can be near the honey, and it will keep them–and you–happy all summer long.

Tips & Warnings

If you find you have ants coming into your home, use any of the above methods around the outside of your house.

Watch out for fire ants. They’re fairly hardy, and if you find them in your garden it may take several methods to finally get rid of them.

  1. Thank you.
    I really appreciate you doing the “ant killing” tips.
    I knew you would have the scoop.

  2. I used cinnamon in my baking cabinet last summer, and it seemed to work. I’ll definitely be doing it again this year! Thanks for all the great info!

    small brown ants are “farming” some kind of larvae in the house. I have seen this with mealy bugs on my outdoor shrubs and palms-but the ants are black and not “microscopic” like these brown ones. There are literally millions of them in and outside of my house. Cannot find the nest.
