7. Diatomaceous Earth
Also known as DE, food-grade diatomaceous earth destroys ants. It’s the powdered fossilized remains of phytoplankton from the sea. Although the powdery pieces are microscopic, they are supremely sharp. When ants eat DE or walk over it, it punctures their exoskeleton. This leaves the insect prone to dry out and die. It won’t take long for your ant problem to disappear. You just have to place a thin layer of DE where ants congregate as well as at entry points to your house. Make sure to keep the DE dry for it to work, and choose food-grade DE because it’s non-toxic.
8. Vinegar
Vinegar is so versatile, we wrote an article listing 17 helpful ways you can use vinegar. Like chalk and soapy water, vinegar removes the ants’ scent trails and leaves them confused and lost. Pour a dollop of vinegar into a spray bottle full of water, shake and spray around your doors and windows. It won’t kill the buggers, but it will keep them from bugging you inside…at least for awhile. Avoid spraying natural stone surfaces like marble and granite.
