Why Use Pesticides that Harm.

There are ways to repel your ants naturally.

Home Remedy to Kill Ants

You can make natural ant repellent and get rid of sugar ants and black ants without toxic chemicals that can hurt your pets or kids. A mixture of borax, sugar and flour kills both roaches and ants. The flour and sugar attract the insects, and the borax kills them. Cocoa powder is an effective substitute for the sugar.
Borax mixtures are also effective against silverfish. The boric acid content in borax damages the insects’ outer skeletons, causing them to dehydrate. More expensive commercial insecticides also use boric acid. Water lowers borax’s effectiveness, making it only suitable for dry locations.
While borax is less toxic than other insecticides, it is still mildly toxic. Users must ensure that children and pets do not have access to borax-based insect bait.

One of the benefits of diatomaceous earth for ant control is that the insects it helps to control have no way to build up a resistance to the diatomaceous earth, like with many of the chemical control insecticides
