how to get rid of ants

We have these little tiny light brown ants that don't want to go away. Though they seem sort of controlled by using Terro.

Here's another formula I might try from Kokua Line.

Question: Is there any low price homemade recipe to put on the kitchen counter to get rid of or kill those pesky black ants found in my sink, counter or trash can?

Answer: Bernarr Kumashiro, insect taxonomist at the state Department of Agriculture, suggests a boric acid mixture that he says works well for most ant species.

A general formula calls for one cup water, 1/3 cup sugar and one teaspoon boric acid powder. Mix well, then put a few drops into small containers, such as something the size of a film canister cover, and place along the ant trail.

Kumashiro warned to keep this away from children and pets.

"If ants do not readily take to the bait, use a toothpick, dab into the mixture, and make a small trail of droplets leading to the container," he said. Refill when the mixture hardens.

"Keep in mind that this is a relatively slow-acting ant poison, and that the worker ants must be allowed to lap it up and take it back to the nest to feed the rest of the colony," he said.

Within a few days, Kumashiro said, "the whole colony will be killed and you should see no ants."

For a few ant species, this concoction won't work. If so, Kumashiro suggests putting a few drops of liquid dishwashing detergent in water in a spray bottle, then spray ants as you see them. This will also get rid of ants, "but new ants will re-appear from the same nest, and this process must be repeated several times," he said.
