What Does Baking Soda Do to Ants?
Baking soda kills ants and has been one of the remedies to infestations by the pesky little insects for a long time. You need to put baking soda in a container and place it near the point of infestation. Some homeowners simply prefer pouring the powder all around. That works too, but it is messy.
The most effective approach, however, is to mix the baking soda with a little sugar to draw in ants, who are attracted to the smell. Adding a little water to make a paste makes it even easier for the ants to eat grab/carry the mixture to their colonies.
How it works
Being a base, baking soda changes the pH of an ant’s body. When the powder comes into contact with the digestive enzymes of the ant, a large amount of carbon dioxide is produced. This gas dries out the ant’s body, killing it in a few minutes.
Why baking soda?
Sodium bicarbonate is harmless if touched or ingested by humans or pets, making it a safe remedy. It is also an easy solution because all you need is a box of the product and a little powdered sugar. A box of baking soda goes for as little as $1 in your local store.
