How To Make Homemade Natural Method to Kill Ants in the House

1 tsp. dishwashing soap (not detergent)
1 tsp. cooking oil (we used virgin olive)
1 qt. water

Mix in a spray bottle. Spray on any soft-bodied insect that invades your house or garden: ants, earwigs, aphids, whiteflies, mealy bugs, etc.

Also spray a barricade line where ants might be entering your house. The only drawback is that it doesn’t work once it’s dried, so if you really want prevention, you have to spray often throughout the day or use other strategies below. This is a good first wave of terror on the bug world, though.
