People have shown interest in how to kill ants organically but organic is a very complicated term which has been overused and misused. In order for something to be considered organic, the compound needs to meet strict guidelines concerning its makeup.
An organic compound consists of a specific number of carbon, hydrogen and oxygen atoms. This is too technical and what you are probably looking for is a more safe and natural way to kill ants.
One of the most natural ways to kill ants is with something called Diatomaceous earth. Diatomaceous earth is naturally occurring and made up of the fossilized remains of hard shelled algae. This makes it a very abrasive.
Diatomaceous earth can be put down where you find ants living. When the ants walk through the substance which can be broken down into a fine, white powder, it will scratch and cut the outside of the ant’s shell. This will cause the ant to either dehydrate or will leave it susceptible to attack by parasites.
When handling Diatomaceous earth you have to be careful not to breathe it in as there is no way to remove it from your lungs. You do not want to use this inside, and when outside, you should work with a mask covering your nose and mouth.
Boric Acid is another very safe alternative for killing ants for it has half the toxicity as table salt yet is very effective. If you choose Boric Acid to get rid of your ant problem you will want to use it for house ants as opposed to the kind you find outside. Outside, Boric Acid can get wet and quickly dissolve.
For an effective, more natural approach to killing ants you find in your yard consider using a Pyrethrum spry. Pyrethrum is made from crushed Chrysanthemums and therefore, very safe and outside it can be effective for up to two weeks.
Pyrethrum will kill a broad spectrum of bugs in your yard with only one application but the downside is that it will also kill the more beneficial insects.
