Homemade Remedy for Ants Inside

I just read in Woman's World to spread salt around the area.

Ants also won't cross a line of salt. For anthills outside, a relatively safe method is to pour large amounts of boiling water on the hill.

Sprinkle baby powder along baseboards and across door entrances. They will not cross over. I stopped them from coming into the kitchen by sprinkling a bit of powder across the doorway into the kitchen.
