1. Gather ½ cup each of baking soda, powdered sugar, and rice flour (rice flour creates a fine texture similar to the white bowl visuals often shared online).
  2. Mix thoroughly in a clean bowl until evenly combined—no lumps.
  3. Spoon small amounts into shallow lids, bottle caps, or disposable dishes.
  4. Position near walls, behind appliances, under sinks, or along known travel paths—but out of reach of children, pets, and non-target wildlife.
  5. Check daily, replace mixture as needed, and wipe away any debris to maintain hygiene.

Additional Natural Support Methods

  • Place cotton balls soaked in peppermint essential oil (diluted) in corners—many studies indicate strong repellent effects on both rodents and roaches.
  • Scatter whole bay leaves in cabinets; roaches reportedly dislike the scent.
  • Use food-grade diatomaceous earth along baseboards as a drying barrier.
  • Seal cracks with caulk and store all food in airtight containers.
