The Best Homemade Natural Ant Killer


antkiller For some reason, the ants this year have been especially bad in our kitchen and bedroom. I make sure all the food is put away and the counters are clean, but they still love to make their ant trails all over my house. It seems to get worse in the summer.  Annoying! We’ve been using Terro liquid ant killer, and it works really quickly, but I don’t want the chemicals in my house. I worry that Penny might get a hold of one of the traps and that wouldn’t be good. Obviously, we make sure they are out of her reach but you never know with a kid around!

My mother in law mentioned that she’s had really good luck with a homemade natural ant killer.  I decided to give it a try, and it works really well!  Here’s how you make it:


-1/2 cup of water
-2 Tablespoons of borax
-1 cup of white sugar

Mix 1/2 cup of water, 2 Tablespoons of borax (the same kind you use in your laundry detergent recipe!), and 1 cup of sugar.  Boil it in a pot for 4 minutes, stirring occasionally.  Allow the mixture to cool and thicken.  When the homemade ant killer is cool it’s ready to use.  We use small plastic containers to put it in.  Just set it on the counter or anywhere in the area that the ants are and let them go to town!  What’s really neat is that borax is actually an ingredient in the Terro liquid ant traps.

The ants love the mixture because it’s nice and sweet, and the borax is like a secret little potion that ends up killing them.  I think it’s very interesting how the ant killer works.  The ants eat the homemade natural ant killer and take it back to the queen for her to eat.  After she eats it she dies, and that should start the demise of the ant colony.

I feel much better about having sugar and borax traipsed around my house versus the chemicals in the Terro liquid ant killer.  There’s been controversy about whether or not borax is safe, but I look at it as a better option over using something that I’m not 100% sure what’s in it.  There are a few options if you’d like something a little easier than making up a liquid ant killer.  You can use cinnamon sticks or peeled garlic cloves near where the ants come in.  For some reason, they do not like either of those scents and it makes them not want to return.  White vinegar also has been rumored to keep ants away.  Just put some in a spray bottle and spray where the ants are coming it.  It should deter them from returning.

Personally we’ve had great success with the homemade ant killer liquid recipe above.  It only has a few ingredients, takes a few minutes to make, and really works!  Give it a try and let me know how well it works for you!

Do you have an ant problem?  Does it seem to be worse at certain parts of the year?
