What is a one-sentence summary of the following article?
Vinegar is such a strong smell that ants will often avoid it. Put some in a spray bottle to use around your kitchen. It's perfectly safe. Just clean your counters first. Then, spray them down lightly with vinegar. Let it dry. The smell will soon dissipate.  In fact, spraying vinegar directly on ants may kill them.  Reapply if you see more ants. Diatomaceous earth has been used as a natural deterrent for ants for years. It's non-toxic, so it's safe to use around kids and pets. However, make sure you get the food-safe variety, not the kind used to filter pools. Then just sprinkle it around where you've been seeing ants. One way to help reduce the number of ants is to use very hot water. The boiling water won't destroy the whole colony, but it will kill about two-thirds of it. Try about 3 gallons (11 L) of boiling water for each large anthill you see. Be very careful with this method. You can be burned both by the water and the steam. An old-fashioned deterrent is bay leaves. You can find bay leaves on the spice aisle, and they are usually still whole (though you can buy ground, too). Spread them out on places where you see ants, and often, the ants will not go in that area.
Try white vinegar. Sprinkle diatomaceous earth. Pour boiling water on mounds outside. Spread out bay leaves.
