(as per Ed Lawrence)
- 2 cups boiling water
- 6 Tablespoons sugar
- 1 teaspoon boric acid
Dissolve the sugar in the boiling water. Add the boric acid and stir until dissolved.
Take any pint-sized plastic container and cut small holes into the sides at the bottom to allow ants access to crawl inside. Dip cotton balls into the solution, and place inside the container. Seal the container with the lid, and place the container on a pathway that the ants are using.
The ants will eat the solution, and take it back to the other ants in the nest, where it will “build up” and eventually destroy the nest. The solution can be refrigerated and stored for a couple of weeks if it is carefully labelled.
