Mix 1/4 powdered sugar to 3/4 baking soda, mix well. Only use powdered (finely granulated) sugar, otherwise the baking soda will not mix in properly, and the ants will get away with just the sugar.
If you are encountering an ant infestation indoors, sprinkle the mixture along windowsills, near doorsteps, or wherever you see high traffic. This method is not instant, which is a good thing, because ants wil lhave the time to carry the baking-soda mixture back to the nest and feed the queen. In a few days your ant problem should be gone.
How does it work?
Much like the old baking soda and vinegar mixture used for homemade volcanos or rockets, this effective pesticide functions the same way. When the baking soda interacts with the formic acid inside the ant's body, it creates carbon dioxde as a by-product gas. Ants' bodies cannot process gas, so they literally eplode.
In other words, NaHCO3 + HCO2H = HCO2Na + H2O + CO2 (KABOOM)!
Perhaps not so dramatic, in reality the gas will just accumulate slowly until the insect collapses, you won't hear a thing.
