Don't tell the authorities, but I'm a cold-hearted killer…of ants. I refuse to tolerate anything with more than four legs living in my house, so each Summer I have a new group of invaders to deal with.
I hate to do so with chemicals, though, especially since I have small children. So I've searched out the best ways to eradicate sugar ants using household items.
Shoot to Kill
To kill an ant instantly, mix a solution of 1 tsp dish soap and 2 cups water in a spray bottle. Spray directly on the ants. They'll die quite quickly, and you can wipe up the "mess" with a paper towel. The soapy water kills the ants and cleans their trail. Two birds with one stone!
The Waiting Game
To get rid of ants for good, you have to get rid of the colony. This takes time. Sometimes a few weeks. But using the right bait will get the job done.
To tackle the colony, you'll need Borax, honey, and old prescription bottles. Mix 1 tsp honey with 2/3 tsp Borax per bottle and place them on their sides wherever the ants' trail is. They'll take this delectable "treat" back to their home and, after a couple weeks, bye bye colony. If the honey/Borax mixture is depleted before the ants are gone, simply make more and refill. Note: Borax should not be ingested by people, so use with caution around children.
Keep them Out
For some reason the little pests dislike calcium carbonate so to keep them out of your house, draw lines with chalk. You can do the same thing inside your home at entry points with flour or lemon juice. If they don't come in, you don't have to get rid of them!
